Boiler for the combustion of solid fuels in a fluidized bed with a burner for liquid fuel combustion

摘要

The invention relates to the field of power.;The boiler consists of a mechanical device in the form of flue narrow, mobile, inclined to the horizontal grate realizing combustion technology in high temperature fluidized bed, heating surfaces feeder fuel ejector. solid fuel infeed is performed in a mechanical feeder booster plate and further into the furnace. The beam is made gastight convective screen providing gases turn in a vertical plane. Applying the two-stage air supply. Primary air is guided under the grate, and a secondary nadsloevoe space. With air ejector entrainment carried back to the furnace for reburning. The combustion chamber is installed along the grating additional heating surface, the cooling plate included in boiler circuit. cooling panel made of a number of tubes, placed above each other closely, and has a U-shaped plan layout. In the upper display device installed flue burner for the combustion of liquid fuel. Feeding liquid fuel into the burner is carried out by the fuel.
