Anti-clogging biomass gasification combustor

Abstract

The invention provides an anti-clogging biomass gasification combustor. The combustor comprises a cavity and a hollow cylindrical combustion chamber, wherein the combustion chamber is communicated with a material feeding tube and an escape pipe; an air chamber is arranged between the cavity and the combustion chamber and is connected with an air pipe; the air pipe is connected with an air adjuster; and an air inlet is formed on the combustion chamber. Air enters the air chamber from the air pipe and then enters the combustion chamber from the air inlet to supplement the needed proper amount air and adjust the temperature in the combustion chamber. Because the air inlet amount of the air pipe is adjusted through the air adjuster, the air inlet amount can be reduced when the temperature in the combustion chamber is more than 1,000 DEG C; ash does not reach the melting point and avoid slagging because of the high temperature; the difficulty in cleaning solidified dregs is eased; and the disturbance on cyclone in the combustion chamber, which is caused by excessive deposited ash and does not contribute to cyclone dust removal, is eliminated.

Description

technical field [0001] The invention belongs to the field of energy preparation, and in particular relates to a combustion device for biomass gasification. Background technique [0002] With the continuous development of the world economy, energy and environmental issues have become increasingly prominent. The main energy sources currently used by human beings are oil, natural gas and coal. According to the statistics of the International Energy Agency, the lifespan of these three kinds of energy for human exploitation on the earth is only about 35 years, 50 years and 240 years respectively. On the one hand, fossil resources such as coal and oil are increasingly depleted, and energy supply continues to be tight; on the other hand, the excessive use of fossil resources has caused increasingly serious environmental problems. Therefore, developing and searching for new alternative energy sources has become a major issue that must be resolved in the new century for the sustain...

AI Technical Summary

Problems solved by technology

The existing combustion technologies are mainly grate layer combustion and fluidized bed combustion technology. Among them, the disadvantages of using the grate layer combustion pot are incomplete combustion of fuel, low thermal efficiency, and high temperature combustion or pyrolysis conditions. , and the generated ash (silicon dioxide and some metal salts) is prone to slagging when the temperature exceeds 1000 ° C. If the amount of slagging is too much, it will block the combustion chamber and affect the combustion effect

However, the use of fluidized bed combustion furnaces is generally only applied to large boilers, which requires huge investment and high production costs, and cannot be vigorously promoted in small and medium-sized enterprises.
