Problems solved by technology

[0003] The existing biomass fuel steam generators are not fully utilized in the utilization of biomass fuel. They only use the heat generated during the combustion of biomass fuel, and do not utilize the heat of the flue gas generated during combustion. a lot of waste
On the one hand, the large amount of heat contained in the flue gas generated during the combustion of biomass fuels has not been utilized; on the other hand, the combustion of biomass fuels is insufficient, the heat in the furnace cavity is lost too quickly, the energy utilization rate is low, and the generation of resources is exhausted. waste

Abstract

The invention discloses a biomass combusting steam generator high in utilization rate. The biomass combusting steam generator comprises a combusting device, a steam generator, a smoke residual heat steam generator and a gas collecting tank. By combining the steam generator and the smoke residual heat steam generator, a combined steam generator is formed; by means of the smoke residual heat steam generator, smoke residual heat is utilized, and the energy utilization rate is greatly increased; by means of the smoke residual heat steam generator, a steam water pipe is directly heated by the smokeresidual heat to generate steam, and the steam is sent into the gas collecting tank.

Description

technical field [0001] The invention relates to a steam generator with high utilization rate of burning biomass. Background technique [0002] The steam generator is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. The biomass fuel steam generator uses agricultural and forestry waste as raw material to solve the problem caused by the burning of straw and other waste in the agricultural production process. Air pollution problem; instead of non-renewable resources to provide power for industry and life, reducing the loss of non-renewable resources. [0003] The existing biomass fuel steam generators are not fully utilized in the utilization of biomass fuel. They only use the heat generated during the combustion of biomass fuel, and do not utilize the heat of the flue gas generated during combustion. A lot of waste. On the one hand, the large amount of heat contained in the flue gas generated during the combu...
