The main points of the fuel gas burner natural gas, liquefied petroleum gas, city gas and other combustible gases, industrial gas burners are widely used, with the view of how to improve the combustion efficiency of biomass heating boiler?
How to improve the combustion efficiency of raw material heating boiler?
Fuel biomass boiler biomass particles, biomass particles relative to other more environmentally friendly fuels, so with a lot of people, so how to improve the combustion efficiency of biomass heating boiler? How to improve the combustion efficiency of raw material heating boiler? 1, sufficient oxygen: if the excess air ratio is too small, i.e., the amount of air supply, increases the solid heat loss and incomplete combustion incomplete combustion of combustible gas heat losses, so reducing the efficiency of combustion; if the excess air ratio is too large, It will reduce the furnace temperature, incomplete combustion to increase heat loss. Optimal excess air ratio so that q2 q3 q4 sum of the minimum value. 2, the use of scaling, cleaning techniques: By using biomass heating boiler scale remover and an electronic scale, a water-steam cycle optimization system, reasonable control blowdown rate of the boiler, thereby reducing the scale, to improve the thermal efficiency of the boiler. Area, good fullness flame on the grate of the flame front position 3, to maintain biomass heating boiler fuel reasonable, flame front should be at the high end and middle grate grate between. When the combustion of the biomass particles, fission first rapid, direct combustion of a portion of another portion of the generated combustible gas (combustible smoke) require secondary oxygenating the secondary combustion, such as lack of oxygen supply is insufficient combustion smoke tube will emit a lot of smoke. causing environmental standards; when the original coal-fired boilers are not designed so that the secondary oxygen to cause a lot of smoke discharge spout will smoke .1, biological particulate combustion, after the second oxygenating the biomass particles generated when the combustor combustible gas (combustible black smoke) after the second post-combustion oxygen to make full use of heat energy to solve the biomass boiler smokestack often, black smoke environmental non-compliance issues. 2, after the second air flow control oxygenating orientation, and sufficiently thermally utilized. Liftoff more significantly thermal efficiency of the boiler.
