Title The calculation and design of powder burner

Abstract With the increasing of energy consumption in nowadays, the traditional non-renewable resources is in restrictions. Biomass energy is gradually taken seriously of its wide range of sources, cleaner-burning, renewable, etc. This paper analyzes the characteristics and development status of biomass energy, and biomass powder in the use of heavy metal waste treatment; calculates the temperature in adiabatic theory of the different fuels; analysis exit temperature of full coverage furnace of the refractory layer; calculates the adiabatic combustion temperature of the fuel and furnace outlet temperature of incomplete combustion; Considers the calculation of temperature with the additional ash; analysis the theoretical combustion temperature of incomplete combustion when the excess air factor is less than 1,and the number calculation of the special ratio of excess air; Creates and analyzes a one-dimensional temperature model of flame stroke for typical fuels . Keywords: Biomass; Combustion temperature; Incomplete combustion; Additional ash ;The ratio of Excess air
