Combustor for gasification combustion of biomass formed particles

Abstract

The invention discloses a combustor for gasification combustion of biomass formed particles. The combustor comprises a furnace body, a furnace head, a furnace pipe, an ash collecting box and a support, and is characterized in that the combustor further comprises a mobile ash discharging plate, a hopper, a screw feeder and a blower fan, wherein the furnace pipe is of the shape of a truncated rhombus, an upper through hole is of a fire outlet hole, a lower through hole is of an ash discharge hole, the whole furnace pipe is arranged at the middle of the furnace body and forms a closed wind box with the furnace body, the blower fan is communicated with the wind box through a ventilation pipe, a plurality of wind holes are uniformly formed on the furnace pipe, the top surface of the furnace body is of the shape of a cauldron, the furnace body and the furnace head form a feeding cavity, the screw feeder is connected with the hopper and connected with the feeding cavity on the side wall between the top surface of the furnace body and the furnace head through a material conveying pipe, an ignition hole is formed on the feeding cavity, a fire through hole is formed at the center of a bottom plate of the furnace head, the rotating ash discharging plate is arranged on the ash discharge hole on the bottom surface of the furnace pipe, and a smoke exhaust port is arranged on the side wall of the furnace head. The combustor takes biomass as fuel, fuel sources are abundant, and environmental pollution is avoided; and furthermore, the combustor has the advantages of reasonable structure, fast ignition, full combustion, high calorific value and great convenience in operation, and is particularly suitable for boilers, tobacco curing furnaces and other drying equipment.

Description

technical field [0001] The invention relates to a burner, in particular to a burner for gasification and combustion of biomass shaped particles, which is especially suitable for use as burners in boilers, flue-cured tobacco furnaces and various drying equipment. Background technique [0002] At present, the burners of small and medium-sized boilers, flue-cured tobacco furnaces and various drying equipment in many places in my country still use coal as fuel. Although coal-fired has the advantages of high calorific value and convenient use, it consumes a lot of energy Petrochemical resources, but also cause serious pollution to people's living environment, endangering people's health. For this reason, many places have restricted the use of coal combustion, or even forbid coal combustion, hoping to replace coal combustion with other fuels. As everyone knows, biomass such as firewood, straw, hay, leaves and wood processing waste is a plant-based fuel with a wide range of sources...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that biomass fuel is difficult to be used in boilers, tobacco flue-cured ovens and other drying equipment heaters, and to provide a kind of biomass fuel, which has sufficient combustion, high calorific value, and little pollution.
