Definitions
- the invention relates to a method and a device for the production of fuel gas from carbonaceous Products, especially those suitably conditioned or processed waste and residues.
- DE-OS 33 12 863 is a method for burning of combustible material in the combustible exhaust gases of a combustion chamber be fed, known.
- DE-PS 34 09 292 and DE-PS 37 05 406 are Gas generator in a unit with a combustion chamber as a so-called Gasification boiler known. These consist of one arranged above a movable grate Filling shaft, one at the filling shaft above the Grate subsequent reaction space, one below the Grate arranged combustion chamber and one inside the Combustion chamber provided flame tube.
- DE-PS 926 978 specifies a gas generator in which the Gasification of the fuel in a cross-flow of the gasification agent he follows.
- the front wall of the gasification duct is designed as an inclined grate, the superimposed, individually switchable wind chambers are upstream. This can be switched off wind chambers optionally, the combustion agent according to need Air or air and steam are fed, causing the combustion process can be influenced.
- the invention has for its object a method and to create a device with which one high energy efficiency the purity of the in one Gasification apparatus generated gas and thus its Usability is expanded.
- a largely full utilization of the used in the Waste or residual carbon one optimal usability of the fuel gas generated and a minimization of the pollutant discharge by which combustion exhaust gases escaping heat become.
- the invention solves the problem for the method with the characterizing means of claim 1 and for Device with the characterizing means of the claim 2.
- Advantageous embodiments of the device Claim 2 are characterized in the subclaims 3 and 4.
- the suitably conditioned or prepared Waste or residues are called solids with air or an air or oxygen-containing gas mixture as Gasifying agent gasified in a gasifying apparatus.
- the substance to be gasified and the gasifying agent in the Mixed flow led by the solid to be gasified passes through the gasification furnace from top to bottom and that Gasifying agents both from above and from below and sideways, at least sideways and on one of the others mentioned places, the solid bed is fed and the extraction of the fuel gas preferably at the lateral supply of the gasification agent opposite Side is done.
- the regulation of the gasification process in the gasification apparatus takes place according to the invention by recording the temperature profile about the height of the gasification apparatus. Doing so the vertical position of the main gasification zone, accordingly the maximum temperature zone, via the movement of the sliding grate and thus the speed of the ash discharge regulated.
- different optimal gasification temperature is about Size and composition of the gasification gas flow and the performance of the gasification furnace across the width of the Gasification agent supply through one above the other Feed points regulated.
- the fuel gas generated can be completely or partially without further processing one under the gasifier in Unit arranged combustion chamber known per se Type supplied and the resulting combustion gases be used thermally.
- the residual heat is by means of a Heat recovery boiler used thermally. After heat removal the combustion exhaust gas is subjected to flue gas cleaning, which preferably contains an activated coke filter, and then gets into the via a chimney The atmosphere.
- the device for the production of fuel gas by gasification carbon-containing products, especially suitable ones Way conditioned and prepared waste and Residues, with air or with air or oxygen Gas mixture as a gasifying agent in one Gasification apparatus, preferably in a unit with one Combustion chamber, is characterized in that the gasifier equipped with a sloping grate is, which is preferably designed as a step grate, the enables the supply of the gasification agent and over a suitable mechanism in a pushing movement is.
- the device the gasifier, surrounded by a two-layer insulation-cooling system, its layers through a perforated partition are separated, the outer insulating layer one or several openings for the cooling air inlet and the inner cooling layer one or more openings for the Have cooling air discharge.
- the cold cooling gas flow usually the gasifying agent
- the outer wall of the insulated cooling system cools, then the flowed through perforated partition and thus in the Follow also on the inner mantle of the gasifier is blown. This leads to intensive cooling the inner shell of the gasifier simultaneous advantageous preheating of the gasification agent.
- the gasifier has a sloping grate 1 equipped, with part of the gasification agent to the gasifying substance is fed through this grate 1 and mainly does the job in the insert bag fully implement any carbon still present.
- Another portion of gasification agent is the gasification furnace fed above the solid bed and has mainly the task of smoldering products of the gasified Flush substance into the gasification zone and thus the complete gasification.
- the bulk of the Gasification agent is laterally over the gasification apparatus a feeder 2 supplied. By varying the width of the Lateral gas supply can be the dimension the gasification zone and thus the gasification performance become.
- the inclined grate 1 is a stepped grate or otherwise than deviating from a flat shape trained and movably mounted as a sliding grate.
- a suitable drive 4 By the thrust movement via a suitable drive 4 is the Ash is discharged through a discharge opening 5 and arrives into the ash collecting area 6.
- the fuel gas is largely removed from the fuel gas and ash free of carbon-containing and mineral suspended particles.
- Another feature of the invention is the insulated cooling system around the gasifier.
- the cooling air arrives first in an outer insulating layer 7 and from there through the perforated partition 8 into an inner cooling layer 9, where the actual cooling of the gasification furnace jacket 12 takes place.
- the preheated air leaves it Insulating cooling system with a 10 outlet and is called Gasification agent or combustion air used.
- the regulation of the gasification process in the gasification apparatus takes place, as already described, by inclusion of the Temperature profile over the height of the gasifier.
- the location of the main gasification zone becomes corresponding the maximum temperature zone, via the movement of the grate 1 and thus regulated by the ash discharge.
- different optimal Gasification temperature is about size and composition of the gasification medium flow and the performance of the gasification apparatus accordingly across the width of the gasification zone the width of the gasifier feed several feeders 2 arranged one above the other are regulated.
- the fuel gas generated can be completely or partially without further processing one under the gasifier in Unit arranged combustion chamber 11 known per se Type supplied and the resulting combustion gases be used thermally.
- the residual heat is by means of a Heat recovery boiler used thermally. After heat removal the combustion exhaust gas is subjected to flue gas cleaning, preferably using an activated coke filter, and then enters via a chimney the atmosphere.
