Abstract

The invention discloses a powdered carbon quick low-temperature combustion smoldering device of a biomass briquette combustion device, and belongs to the technical field of biomass combustion. The powdered carbon quick low-temperature combustion smoldering device is characterized in that the two ends of air inlet pipes (27) communicate with the outer side of a smoldering pool (20); air outlets are formed in the pipe walls of the air inlet pipes (27); flowing air is introduced into the air inlet pipes (27) to cool the smoldering pool (20); a part of air in the air inlet pipes (27) enters the smoldering pool (20) to assist combustion; the air inlet pipes (27) are further connected with an air volume adjusting unit used for adjusting the flow velocity of cooling air; a combustion assistance adjusting mechanism is connected with the air inlet pipes (27); and the combustion assistance adjusting mechanism cooperates with the air volume adjusting unit to adjust the volume of combustion-supporting air entering the smoldering pool (20). According to the powdered carbon quick low-temperature combustion smoldering device of the biomass briquette combustion device, coking and slagging of fuel and volatilization of potassium, sodium and chloride elements are avoided, problems of gas and solid pollutant emission and equipment sticky dirt due to straw combustion are radically reduced, and ash can be directly utilized in farmland fertilizers.

Description

technical field [0001] The utility model relates to a smoldering device for fast and low-temperature combustion of carbon powder in a biomass briquette fuel combustion device, which belongs to the technical field of biomass combustion. Background technique [0002] Straw accounts for 70% of my country's biomass energy, and clean and reliable straw combustion technology is the key to the application of biomass energy in my country. Biomass fuels such as straw contain a large amount of elements such as potassium, sodium, and chlorine. If the solid phase temperature is high during combustion, especially when it exceeds 800°C, these elements will volatilize and soften. Part of the volatilized potassium, sodium, and chlorine compounds will condense on the surface of the furnace heat exchanger to form sticky dirt, and the other part will be discharged into the atmosphere with the flue gas to form aerosols. The softened potassium and sodium compounds in the bottom ash will form sl...
