(3) bed of material on the fire grate 4 with from the air catalytic combustion of fire grate upper surface 15 and side vents 16, under the promotion of auger conveyor 11, the bed of material slowly moves also after-flame gradually equably on fire grate, the lime-ash that burning generates is pushed to fire grate 4 front ends gradually, drops into automatically in the ash bucket 6 of 2 belows, combustion chamber;
(4) flue gas of burning generation is walked around the smoke deflector 14 outflow combustion chambers 2 on 2 tops, combustion chamber, at first through the fuel in the flue gas interlayer 13 heating pyrolysis chambers 8, and then passes exhaust gases passes 9 and discharges combustion furnace 1.
Before whole burner is started working, also need earlier combustion furnace ignition, concrete grammar is as follows, pulls out ash bucket 6, opens fire door 5, place a small amount of biomass molding fuel and combustibles on the fire grate 4 and light, close fire door 5 subsequently rapidly, and push ash bucket 6, under the effect of combustion air little negative pressure in combustion chamber 2, be inhaled into along air channel 10 in the air compartment 17 of fire grate 4, pass fire grate upper surface 15 and sidewall air supply hole 16 and enter in the combustion chamber 2 combustion-supporting.
In the above-mentioned combustion process, biomass molding fuel is stored in the hopper 7, along with the mobile of fuel progresses in the pyrolysis chamber 8, is subjected to the heat heating from flue gas in combustion chamber 2 and the flue gas interlayer 13, pyrolysis under 300-800 ℃ low temperature and oxygen free condition generates volatile matter and semicoke gradually; Utilization is positioned at the auger conveyor 11 of 8 bottoms, pyrolysis chamber, and the semicoke of generation is pushed in the fire grate 4 according to given pace, contacts with air that the side is sent into fire grate 4 bottoms to take fire; Enter the semicoke layer and the burning common of passing in the combustion chamber 2 on the fire grate 4 under the effect of volatile matter little negative pressure in combustion chamber 2 with it, after-flame gradually when semicoke slowly moves on fire grate 4, the lime-ash of generation slowly is moved to fire grate 4 front ends and falls into ash bucket 6 along with the motion of semicoke layer on fire grate 4; Be introduced in the flue gas interlayer 13 after the flue gas that burning produces is walked around smoke deflector 14, utilize its waste heat heat hot to separate fuel in the chamber 8, discharge along exhaust gases passes 9 subsequently.
Can regulate the burning load of burner by the rotating speed of adjustable screw conveyer 11.When the rotating speed of auger conveyor 11 reduces, fuel and the semicoke translational speed in pyrolysis chamber 8 and on the fire grate 4 slows down, the combustible that enters in unit interval in combustion chamber 2 and the fire grate 4 reduces, flue-gas temperature in the combustion chamber 2 in temperature and the flue gas interlayer 13 reduces, cause pyrolysis chamber's 8 interior temperature also to reduce, the pyrolysis rate of biomass molding fuel slows down, and the speed that generates volatile matter and semicoke reduces, thereby realizes low load combustion; When increasing the rotating speed of auger conveyor 11, burning load increases.
In the combustion process, biomass molding fuel is low temperature Non-oxygen pyrolytic in pyrolysis chamber 8 at first, after volatile matter is slowly separated out, entering combustion chamber 2 burns jointly with semicoke, volatile matter and the semicoke contradiction aspect burning velocity is not outstanding, improve the matching between volatile combustion and the coal-char combustion, be convenient to solve the air-supply problem of biomass molding fuel burning, improved efficiency of combustion; After volatile matter enters combustion chamber 2, the part volatile matter burns jointly with semicoke in the semicoke layer, the high heating value that volatile combustion discharges helps improving the burn-off rate of semicoke, reduce the phosphorus content in the lime-ash, and because fully the contacting of volatile matter and semicoke layer, the time of staying of flue gas in scorching hot semicoke layer increases, and reduced the content of imperfect combustion material in the flue gas, reduced the jet-black discharging in the combustion process.In addition, part volatile matter and semicoke burn jointly, have improved the contact probability of flue gas and semicoke layer, the NO in the flue gas
xCan effectively be reduced into N by semicoke
2Thereby, reduce the NO that burning produces
