(5) specific embodiment:

Referring to Fig. 1-Fig. 5, the utility model comprises combustion chamber and step-like fire grate 1, its key technology is that the combustion chamber is divided into reative cell 12 and reduction chamber 11, fire grate 1 is made of the empty stomach V-type groove that links to each other between grid section up and down on an empty stomach and the grid section, the abdominal cavity of grid section and V-type groove connects and forms fluid passage 2, be cast with catalyst 13 in the V-type groove, the junction between the V-type groove is provided with hole seam 9.Storage tank 15 and steam fort 14 are installed in the furnace wall, storage tank 15 connects water level control box 16, adjustment case 17 successively by pipeline, storage tank 15 is installed in the top in the furnace wall, water level control box 16, adjust case 17 and steam fort 14 be installed in fire grate in the furnace wall below.The case 17 of adjusting is communicated with fluid passage 2 by pipeline, and fluid passage 2 is connected with steam fort 14 by pipeline, is connected with isocon 3 on the steam fort 14 and is positioned at reative cell 12 and reduction chamber 11, has eyelet on the isocon 3.Outside the furnace wall, install successively and be connected with air compressor 5, filter 6, magnetic valve 7, cylinder valve 8 and movable push 4, on magnetic valve 7, be provided with time controller 10.

Scale remover, sulphur-fixing agent, co-catalyst oxygenation are housed in the water level control box 16 increase hydrogen agent etc. and constitute the complexing agent agitator tank, form system's catalytic combustion system.Provide source of the gas to be used as power by air compressor 5 during work, air enters filter 6 through pipeline and filters, enter cylinder valve 8 through magnetic valve 7 controls, send instruction control cylinder valve 8 by time controller 10 to magnetic valve 7 and promote movable push 4 round operations on time, coal is advanced in the burner hearth.Air compressor 5 is regularly inflation operation intermittently, power consumption 1.5kw/h, and every day, the power consumption less than was 13 yuan.With this covering device coal is advanced in the furnace chamber, the automaticity height alleviates labor strength, saves cost of labor.

Reative cell 12 is that the growth section of chamber 11 is promptly now reduced in former combustion chamber.According to the coal burning process is exactly chemical reaction process mechanism, finish drying, destructive distillation and abundant oxidizing fire before in reative cell 12, having enough room and times to guarantee coal combustion, make the pollutant flue dust that the chain rupture dehydrogenation reaction is separated out when low temperature, 11 is burned most through the high temperature reduction chamber, stitch jet vapor by isocon 3 to the hole simultaneously, capture floating dust so enter fire grate, avoided the discharging of pollutant with this through the hole seam.

Water circulation cooling during coal burning in the fluid passage 2 is staged fire grate device on an empty stomach, makes its effective cooling, and the protection burner increases the service life.The steam that the heat absorption of water circulation simultaneously produces is in pipeline enters steam fort 14, and the eyelet ejection of the steam in the steam fort 14 on isocon 3 with the carbon dioxide reaction of red heat, increases the effective rate of utilization of new forms of energy with this, newly-increased again energy saving way in energy-conservation.

Catalyst 13 is through high-temp glue cohesion disposal molding, the composite catalyst validity response that is heated, and under the catalysis effect of mass transmitting, the free carbon (black smoke) that is about to generate is decomposed into CH when destructive distillation ₄, CO gas closes after-burning with oxidation in the lump and burnouts, the thermal energy conduction of generation, convection current, radiation give heated products or heat up water utilize, with this with CO, CH ₄Turn harm into good with free carbon, thereby be converted into heat energy and energy savings, resource.

Hole seam 9 is automatic oxygen uptake and composite vapor under suction function, is penetrated in the hydrocarbon side chain in coal seam through the slit, with foreign material generation exchange reaction intrinsic in the charcoal, as the H in oxygen and the water ₂Generate ammonia with the nitrogen oxide combination reaction, simultaneously and calcium oxide, magnesia, aluminium oxide and iron sulfide, under catalyst action, produce synergy, have complementary advantages, be used as building materials in the charcoal lime-ash and make innoxious use thereby oxysulfide is fixed in.And nitrogen oxide has been converted into N ₂, CO ₂And H ₂O makes environment exempt from murder by poisoning!
