Definitions
- the invention relates to a method for gasifying fuel in the fuel channel of a gasifying generator, the fuel channel having a combustion area for fuel combustion and one or more oxidation pipes for supplying oxidation gas to the combustion area.
- the invention also relates to a gasifying generator used in the method.
- the fuel is generally supplied to the upper part of the gasifying generator, from which it flows by means of gravity through the pyrolysis, combustion and reduction areas.
- the heat required for gasification is obtained by burning fuel, whereby a pyrolysis area is formed between the combustion area and the fuel, in which the volatile materials are separated from the fuel. These volatile materials form the product gas of the gasifying generator together with the gases generated in the reduction area.
- the prior art gasifying generators are divided into cocurrent gasifiers and counter- current gasifiers according to the oxidation gas supply method.
- cocurrent gasifi- ers the oxidation gas is fed directly to the combustion area.
- countercurrent gasifiers the oxidation gas is conducted upwards from below, in the direction opposite to the fuel flow. In this method, the pyrolysis products end up in the product gas almost as such, i.e. the tars do not decompose.
- An essential property of the product gas created in the gasifying generator with regard to its use is its purity.
- tar generated in the gasification is a problematic ingredient of the product gas because of the emissions caused by it, limitations of use and the problems caused to the equipment.
- Tar compounds decompose in temperatures exceeding 850°C.
- Another essential impurity that arises in gasification is the nitrogen oxides that are generated in temperatures exceeding 1000 0 C. For these reasons, temperature control especially in the combustion zone after the pyrolysis phase is important in gasification.
- Patent publication GB 456111 A describes a gasifying generator, in which oxidation gas is fed by oxidation pipes into the fuel channel.
- the oxidation pipes are movable inside the fuel channel. This adjustment possibility has been made for enabling the adaptation of the gasifying generator for different fuels.
- the location of the oxidation pipes is not changed during the combustion event.
- An attempt is i made to control the combustion event by adjusting the amount of oxidation gas getting into the oxidation pipes.
- the advantage achieved by the possibility of moving the pipes is that the oxidation pipes can be installed at different heights in the fuel channel. Adjusting the temperature of the combustion event is cumbersome with the method described in the specification.
- oxidation pipes coming from above cause additional friction in the fuel flow, and the oxidation gas may form flow channels in the vicinity of the surface of the oxidation pipe.
- the gasifying generator used in the method according to the invention there is a body, a fuel channel for fuel feed and the gasification processes, and one or more oxidation pipes for feeding the oxidation gas to the fuel channel.
- the invention is characterized in that the oxidation gas discharge ends of the oxidation pipes are movable within the fuel channel in such a way that the point of oxidation can be moved in the gasification process.
- the temperature of the combustion area is controlled by moving the oxidation pipes against the fuel stream or in the direction of the fuel stream.
- the oxidation pipes can be moved either separately or in groups.
- the number of oxidation pipes can be selected according to the size of the gasifying generator and the desired control accuracy of the combustion process.
- Each oxidation pipe can have its own combustion area, but they have a common fuel feed and lower combustion area.
- the fuel channel of the gasifying generator can have a narrowing or other structural solution, which restrains the free flow of the fuel.
- the combustion area is generally located at this narrowing.
- the temperature of the combustion area is measured by a thermometer.
- the thermometer is preferably connected to the first actuator, which controls the oxidation pipes and especially their oxidation gas dis- charge ends within the fuel channel.
- the first actuator adjusts the location of the oxidation pipes on the basis of readings obtained from the thermometer according to predetermined instructions.
- This first actuator may be computer-controllable, automated in some other way or manually controllable. In the method, the temperature is given a desired set value, which is given to the first actuator or some device controlling it.
- the first actuator moves the oxidation gas discharge end of the oxidation pipes in the direction of the pyrolysis area, whereby the combustion area receives less oxidation gas, combustion slows down in the combustion area, and the temperature thus falls.
- the oxidation gas discharge end of the oxidation pipes is moved towards the combustion process, whereby the combustion in the combustion area accelerates and the temperature rises. It has been found experimentally that the best results with regard to the gasification processes and the product gas are obtained when a temperature exceeding 850 0 C is chosen as the set value of the temperature.
- the cross-sectional area of the fuel channel can be changed by one or more movable adjuster(s) for adjusting the fuel flow and for determining the size of the combustion area.
- These adjusters are in compliance with the prior art as such.
- One possible way of implementing the adjusters is to place in the fuel channel two heat-resistant plates perpendicular to the main axis of the fuel channel, which move towards each other from the opposite sides of the fuel channel and thus reduce the cross-sectional area of the narrowing. In order to increase the cross- sectional area of the fuel channel, the plates are moved away from each other.
- thermometer measuring the temperature of the combustion area is connected to the second actuator, which changes the position of the movable actuators that adjust the cross-sectional area of the fuel channel. Then the second actuator con- trols the position of the adjusters on the basis of readings obtained from the thermometer in accordance with predetermined instructions.
- the cross-sectional area is reduced, the amount of materials evaporated in the pyrolysis area is reduced and more carbon is burnt in the combustion area, in which case the tem- perature rises.
- the cross-sectional area is increased, the temperature of the combustion area can be reduced, because the pyrolysis phase accelerates and more material to be heated gets to the combustion area.
- This second actuator may be computer- controllable, automated in some other way or manually controllable. Adjusting the cross-sectional area thus also changes the size of the combustion area. This can be used for adjusting the power of the gasifying generator and for compensating for the properties of the fuel.
- the combustion process of the gasifying generator can be controlled and its temperature caused to remain within the desired limits.
- the invention also relates to equipment for applying the above described method.
- the equipment comprises a gasifying generator with a body, a fuel channel for fuel feed and the gasification processes, and one or more oxidation pipes, by which oxidation gas is fed to the combustion area.
- the equipment is characterized in that the oxidation pipes are movable within the fuel channel for feeding the oxidation gas to the desired point in the fuel channel.
- the oxidation pipes are arranged to be adjusted separately or in one or more groups.
- thermometer for measuring the temperature of the combustion area.
- the thermometer is preferably connected to the first actuator, which has been programmed to adjust the location of the oxidation gas discharge end of the oxidation pipes within the fuel channel in accordance with the measurement results obtained from the thermometer.
- the gasifying generator has an oxidation pipe essentially parallel with the longitudinal axis of the fuel channel, to which the oxidation gas has been directed and from the discharge end of which the oxidation gas flows out to the desired area.
- the fuel channel is preferably vertical.
- the pipe moving mechanism is a solution suitable for the purpose, which may be, for example, a hydraulic or motorized solution. The movement of the end of the pipe takes place between the pyrolysis and the combustion areas. The flow of the gas is accomplished ei- ther by over- or underpressure.
- the discharge end of the oxidation pipe has been formed in such a way that the oxidizer gas coming from it remains in the desired place and does not disturb the movements of the fuel flow.
- this has been done by adding to the discharge end of the oxidation pipe an oxidizer gas controller, which guides the gas to the near environment of the oxidation pipe to an area in which the oxidizer gas is wanted to have an effect.
- the pipe can be closed and have holes made in it, which direct the discharge of the oxidizer gas in the desired direction.
- the oxidation pipes can have ro- tatable discharge ends for guiding the oxidizer gas.
- the place of oxidation can be controlled in many different ways.
- the pipe or pipes may come from the sides of the body of the gasifying generator, for example, and can be directed therefrom to the desired point, or the pipes are otherwise entirely outside the body, but their discharge ends coming to the fuel channel have been shaped in a way that their movements can be used to guide the oxidation gas jets in the fuel channel.
- a lower combustion area in the lower part of the gasifying generator in which the carbonized resi- due formed in the gasification processes is burnt up.
- Oxidizer gas is led to this lower combustion area by its own, separate feed connection.
- This lower combustion causes the reduction area to flow downwards, and the ash created in the actual combustion area cannot thus block the fuel channel. This also reduces the amount of ash created.
- the product gas of the gasifying generator according to the invention can be led out from the gasifier for the desired purpose.
- the gas created can also be combusted in the gasifier itself after the reduction area, in which case the gasifying generator according to the invention can be used for heat production, for example.
- the materials of the parts used in the gasifying generator described are preferably metallic, ceramic or other materials that withstand high temperatures.
- the invention has the advantage that it improves the purity and quality of the product gas. It has been found in analyses that the composition of the product gas obtained by the method according to the invention is, on the average, 21 % CO, 15% H 2 , 11% CO 2 , 2% CH 4 , while the rest is mainly nitrogen, which is a relatively good result.
- the purity of the product gas enables its use in a versatile manner. In addition, it simplifies and makes the costs of manufacture and use of the equipment lower than earlier.
- the purification process of the product gas is also substantially simplified.
- the invention has the advantage that the temperatures are accurately controlled, and thus the gasification reactions also remain under control and do not produce undesired ingredients, such as tar compounds, which could harm the processes and the operation of the gasifying generator by accruing onto the inner surface of the fuel channel, for example.
- the invention has the advantage that the fuel will thus be used as efficiently as possible, and the process becomes more economical than the earlier solutions.
- Fig. 1 shows a cross-section of a preferred embodiment of a gasifying generator according to the invention.
- Fig. 1 shows an example of a gasifying generator according to the invention, used in a vertical position, in cross-section.
- the gasifying generator has a cylindrical body 1 , inside which there is a fuel channel 2, which mostly follows the shapes of the body.
- a fuel channel 2 In the upper part of the fuel channel there is fuel feed equipment 3.
- the feed equipment 3 is closed by an airtight cover 25, which is only opened when fuel is added.
- the fuel channel 2 can be divided into the following areas: the area of uncombusted fuel 4, pyrolysis area 5, combustion area 6, reduction area 7 and the lower combustion area 8.
- the area 4 of uncombusted fuel is uppermost and the lower combustion area 8 is the lowest.
- oxidation pipe 10 Inside the fuel channel there is an oxidation pipe 10, in the first upward pointed end of which there is a discharge end 11 , from which the oxidizer gas is directed to the combustion area 6.
- the oxidation pipe 10 runs in the fuel channel 2 in the direction of its longitudinal axis.
- One end of the oxidation pipe extends through the bottom of the fuel channel to the chamber 13 in the lower part of the body.
- the oxidation gas transport system belonging to the gasifying generator also comprises oxidation gas transport piping 12 running around the fuel channel 2, the first end of which opens outside the body 1 and the second end of which leads to a chamber 13 in the lower part of the body.
- the oxidation gas is pumped through the transport piping to the chamber, in which overpressure is formed.
- the second end of the oxidation pipe 10 extending to the chamber 13 has been connected to the first actuator 14, by which the oxidation pipe can be moved in the up and down directions within the fuel chamber.
- the oxidation pipe 10 is surrounded at its lower part by a casing pipe 9 fixedly installed to the body 1 , which penetrates through the bottom of the body 1 of the gasifying generator, and the upward pointed aperture of which has been sealed so that when the oxidation pipe 10 is moving, no oxidation gas gets to the fuel channel from the overpressurized oxidation gas chamber 13.
- the lower combustion area 8 in the lower part of the fuel channel 2 gets its oxidation gas along the oxidizer pipe 15.
- the ash and other material accumulated on the bottom of the fuel channel 2 are removed by an ash removal system 16, which leads the ash to the container 17. This technique is known as such.
- the fuel channel 2 has a narrowing 18, which has been implemented by shaping the fuel channel at this point to the shape of a narrowing and opening funnel.
- a thermometer 20 At the point of the narrowing in the fuel channel there is a thermometer 20 and movable adjustors 19 for changing the cross-sectional area of the fuel channel.
- the movable adjustors 19 that change the cross-sectional area of the fuel channel are controlled by the second actuator 21.
- thermometer 20 and the first and the second actuators 14 and 21 of the cross-sectional area control means are connected to a control unit 22, which controls their operation.
- This control unit is preferably a computer.
- the product gas created in the fuel channel 2 is led out from the gasifying generator to the product gas outlet pipe 23.
- the processing of the product gas in the generator and the method for bringing it outside the body depend on the purpose of use of the product gas and the generator.
- the gasification process takes place in the following manner: Inside the body 1 of the gasifying generator there is a fuel channel 2, in which the gasification processes take place.
- the fuel is fed to the upper part of the fuel channel 2 by fuel feed equipment 3.
- the fuel flows by means of gravity to the pyrolysis area 5 heated by the combustion area 6, where volatile materials are separated from the fuel.
- the fuel flows further to the combustion area 6, in which it participates in the combustion reaction, which is maintained by the oxidation gas coming from the discharge end 11 of the oxidation pipe 10.
- the combustion gases, carbonized residue and ash created in the combustion area 6 are moved to the reduction area 7, where the combustion gases are reduced.
- the carbonized residue created in the reactions mentioned above is burnt up in the lower combustion area 8, to which oxidation gas is led from the pipe 15.
- the combustion waste created can be removed by ash removal equipment 16, which leads the waste to the container 17.
- the product gas generated in the process exits from the gasifying generator along the discharge pipe 23.
- the temperature of the combustion area 6 is measured by a thermometer 20.
- the measurement results given by the thermometer are read by the control unit 22. If the measured temperature is higher than the temperature set value given to the control unit 22, the first actuator 14 raises the oxidising pipe 10. Then the discharge end 11 of the oxidation pipe moves towards the pyrolysis area 5, whereby the amount of oxidation gas in the combustion area 6 is reduced, the combustion process slows down and the temperature falls.
- control unit 22 can also be used to control second actuator 21 , which, when it is desired to lower the temperature measured by the thermometer 20, increases the cross-sectional area of the fuel channel 2 by adjustors, whereby the pyrolysis reactions accelerate and more material to be heated comes to the combustion area, and thus the temperature of the combustion area falls.
- second actuator 21 when it is found by the control unit 22 that the temperature of the combustion area 6 measured by the thermometer 20 is too low compared to the set value, the oxidation pipe 10 is lowered by the first actuator 14. Then the dis- charge end 11 of the oxidation pipe directs more oxidation gas to the combustion area 6, causing the combustion process to accelerate and the temperature to rise.
- the pyrolysis reaction is attenuated and thus more carbon, which can participate in the combustion, comes to the combustion area 6.
- the combustion reaction is intensified.
- the temperature of the combustion area 6 can be made to stay within the desired limits.
- the adjustment of the temperature of the combustion process is mainly accomplished by moving the oxidation pipes 10.
- the system according to the invention can also be implemented in ways that differ from those described above.
- the entire gasifying generator can be in some other than vertical position in the system.
- some adjustments can be implemented manually or automatically according to predetermined programming. Only one oxidation pipe is shown in the preferred embodiment of the gasifying generator in Fig. 1. There can naturally be more than one oxidation pipe, and they can be moved either each one separately or in groups.
