An air-cooled biomass burner

Abstract

The invention discloses an air-cooled biomass burning machine, which comprises an inner tank, an outer shell, an air supply device and a biomass feeding device. The inner liner is located in the outershell, and there is a gap between the inner liner and the outer shell; the inner liner is provided with a grate, a fire nozzle, and a fire nozzle leading to the outer shell, and the fire nozzle is located above the grate; The air outlet of the air supply device opens into the gap between the inner liner and the outer shell, and after being discharged from the gap, the air outlet opens into the inner liner from below the grate, the biomass feeding device is located above the grate, and the flame generated by biomass combustion on the grate is sprayed out from the fire outlet by the wind power.The invention has the advantages that: air from the air supply device passes through the gap between the liner and the housing, The heat dissipation of the combustor is good, and the air after heat dissipation enters the interior of the inner liner through the grate from below the grate, so that the heat of the hot air after heat dissipation can be reused in the combustor, thereby saving energy and providing oxygen for the combustion of biomass to ensure the full combustion of the biomass.

Description

Technical field [0001] The invention relates to the field of combustors, in particular to an air-cooled biomass combustor. Background technique [0002] With the tension of power shortages, oil shortages, rising electricity prices, and rising oil prices, as well as increasing environmental pollution problems, various industries have begun to gradually increase their awareness of the use of renewable energy. Among them, the use of biomass energy is currently the most practical A feasible solution. Biomass is a substance that exists on the earth. It includes all animals, plants and microorganisms, as well as many organic substances derived, excreted and metabolized from these living substances. All kinds of biomass have certain energy. Using biomass as a carrier, the energy produced by biomass is biomass energy. Biomass energy is a form of energy stored in organisms in the form of chemical energy from solar energy, directly or indirectly derived from photosynthesis of plants. T...
