Abstract
Disclosed is a gas distribution and combustion technology of gas-fired equipment. In a proper period, under the condition of guaranteeing the effect that the size concentration and combustion state of gaseous fuel in the gas-fired equipment are relatively stable, gaseous methyl alcohol is added to form mixed type alcohol-alkane gas fuel with methane as the main component. The method is used for actively adjusting the calorific value of natural gas, lowering the cost, saving energy and reducing emission. The gas distribution and combustion technology is used for the gas-fired equipment in a power plant and an industrial gas-fired boiler.
Description
Technical field natural gas power
The gas fuel in background technology clean type power plant belongs to the environmentally friendly fuel of golf calorific value, but its price unit caloric value high, benchmark concentration can not regulate, and consumption is big, causes that many Natural Gas Power Plants are in the state of heavy losses all the year round.
Because price and the performance thereof of gas raw material all lack the former of active adjustment means and thus result in the phenomenon that similar power plant occurs universality to lose, become " clean electric power generation " pattern and promote one of main cause of being obstructed in the whole nation, have influence on technological progress and the follow-up developments of power industry.
How in the suitable period, ensureing in gas-fired equipment under fuel gas volumetric concentration and the metastable premise of fired state by acceptable mode and cost, the caloric value of active adjustment fuel gas?
Prior art there is no effective solution.
It is that one is not volatile that prior art [natural gas synergist] (has another name called natural gas catalysis Synergistic additives, rare earth fuel gain agent), meet fiery nonflammable material, itself is not fuel, does not possess the feature of replaceable natural gas.
After natural gas synergist potentiation, combustion of natural gas temperature reaches 3300 degrees Celsius, can be used for metal solder, but is unsuitable for boiler and uses.
The cost of material of natural gas synergist and use cost are high, so far except for metal solder, there are no the report using this additive in gas-fired equipment, Industrial Boiler or civil boiler.
Summary of the invention
The solution of the present invention is: gas fired-boiler uses simple natural gas (its composition is mainly methane) and changes into the gaseous mixture using methane with methanol. That is, gaseous methanol is moderately introduced natural gas, to the application of natural gas being played the effect that can modulate.
The technology path of this programme is, with reference to gas-fired equipment or the boiler technology requirement to fuel gas, by carbinol-modified and mix natural gas after gasification, become the adjustable gaseous mixture based on natural gas of combustibility, thereafter purified, homogenizing, current stabilization, inputs gas-fired equipment.
Advantage and effect:
Good economy performance. The physico-chemical property of gaseous methanol and natural gas (methane) similar compatibility, intermiscibility is good, safe ready, and the burning earthquake intensity that this technology is displacer gas and adjustment fuel at low cost creates possibility.
Burning is optimized. The burning of natural gas belongs to high-temp combustion, and under hot conditions, in natural gas, contained some becomes branch that dissociation reaction occurs. It is all the endothermic reaction in view of dissociation reaction, it is meant that the completeness of burning is lowered, and this is undesirable. And mix burn methanol Flame of Natural Gas length long, temperature is relatively low, and its burning earthquake intensity adjustable at random, occur dissociation reaction probability decline, fuel combustion is obtained by reacting optimization, fuel and heat and is utilized more fully.
Nitrogen oxides reduces. Nitrogen oxides only just has the possibility of generation under the high temperature conditions; Natural gas mixes burning gaseous methanol can reduce the surface temperature of flame, thus weakening the condition of NO_x formation, reduces environmental pollution.
It is easy to regulate. The volumetric concentration of gaseous fuel is to ensure the essential condition that gas fired-boiler surely burns. Under ensureing the metastable premise of combustion gas volumetric concentration, by the gradual change of natural gas Yu gaseous methanol mixing ratio, it is possible to random regulating gas equipment or the steady of boiler burn temperature and some parameter.
Compound additive containing components such as antistatic additive, anticorrosive metal agent, rheological agents is added in methanol by embodiment 1, completes the modified of liquid methanol. Need the used time, modified liquid methanol is gasified, mix use in natural gas by calculating consumption.
The use of embodiment 2 compound additive: need smoothly with gas flow rate according to different tube diameters, unlike material, different pressures and guarantee flow rate of liquid, the increase and decrease of agent component or quantity can be added.
The method of embodiment 3 materials safety gasification: use the various thermals source of solid-state, liquid, gaseous state, including boiler afterheat, end steam, flue gas etc., the standby methanol of modified liquid is heated to gasification in heat exchanger, and the explosion-proof air accumulator that gaseous methanol then inputs constant temperature stores.
The pipeline conveying of embodiment 4 gaseous methanol thermal isolation and heat storage, it is to avoid condensation and liquefaction occur in course of conveying.
Embodiment 5 gaseous methanol and the mode of Gas Exploitation pipe-line blending, be pressed into natural gas line with pump by the gaseous methanol from air accumulator, by the power in pipeline and potential energy, make two kinds of gaseous materials mix and homogenizing mutually with diffusion process in flowing.
Embodiment 6 gaseous methanol and natural gas also can adopt the mode of premixing, namely in the outer ad hoc premixed device of gas distributing system, in advance gaseous methanol is mixed with natural gas also homogenizing it.
