Description

technical field

[0001] The invention relates to a boiler, in particular to a jacketless boiler with a biomass furnace. Background technique

[0002] After PM2.5 is included in the national standard, the problem of urban ambient air quality is facing severe challenges, especially the burning of fossil fuels pollutes the environment, which is not conducive to energy conservation and environmental protection. Utilization, most of the furnaces of existing biomass boilers are equipped with water jackets, which reduces the combustion temperature of the furnace, and insufficient combustion leads to a decrease in thermal efficiency and increases the emission of smoke and dust. The fuel deposits on the heating surface of the furnace during combustion, and the deposition will gradually thicken with the prolongation of the production time, which will gradually reduce the heat exchange sequence, and in severe cases, it will cause damage to the heat exchange tube, water leakage, and inte...
