Biomass gasifying furnace

Abstract

A biomass gasifying furnace is characterized in that the main body of the biomass gasifying furnace is a cylindrical gasifying furnace cylinder body, and a residue removal machine and an ash hoist are respectively arranged above and below a gasifying furnace baseboard. The gasifying furnace cylinder body is divided into an external cylinder body and an internal cylinder body, the wall of the external cylinder body and a downward extension wall jacket form a combustion gas channel, the lower end of the combustion gas channel is connected with a hearth, and the sidewall of the external cylinder body is provided with a combustion gas outlet; a flow divider is positioned in the middle portion of the hearth, and the circumference of the hearth is provided with gas outlets; and the residue removal machine is arranged below the flow divider, the upper portion of the residue removal machine is a conical cap, the middle portion of the conical cap is connected with a residue removal machine ventilating tube, and a residue removal machine support medium shaft is supported on a transmission shaft connected with a residue removal machine motor. The sidewall of the external cylinder body is provided with high temperature air inlets, and is connected with the flow divider through the residue removal machine ventilating tube; and the bottom of the gasifying furnace baseboard is connected with an ash discharge machine. The biomass gasifying furnace has the advantages of complete conversion of heat energy of biomass fuels, conversion of tar in the combustion gas into permanent gas molecules in high temperature environment, reduction of damages to devices, and improvement of the calorific value of the combustion gas.

Description

technical field [0001] The invention relates to a biomass gasification device, in particular to a high-temperature gasification and cracking equipment for biomass fuel. Background technique [0002] At the beginning of this century, my country's biomass gasification technology has developed rapidly. Various gasifiers such as up-suction, down-suction, open-heart, side-suction, and fluidized-bed gasifiers can stably produce biomass gas. The produced biomass gas is sent to users after washing, filtering and purification, and the market is very active. However, during the use of the gas produced, washed, filtered, and purified by the above furnace type and series of supporting equipment for about ten years, the tar in the gas has seriously blocked the gas pipeline, gas stove and generator, and seriously hindered the production of biomass. Development of the gasification market. [0003] The above-mentioned gasification equipment uses air at normal temperature as the gasificatio...

Problems solved by technology

However, during the use of the gas produced, washed, filtered, and purified by the above furnace type and series of supporting equipment for about ten years, the tar in the gas has seriously blocked the gas pipeline, gas stove and generator, and seriously hindered the production of biomass. Development of the gasification market

[0003] The above-mentioned gasification equipment uses air at normal temperature as the gasification agent, and then uses washing, filtering, and purification devices and processes to remove tar from the biomass gas released from the furnace. Practice has proved that the symptoms are not cured
