Smoldering device for fast and low-temperature combustion of carbon powder in biomass briquette fuel combustion device

Abstract

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. It is characterized in that: the two ends of the air inlet pipe (27) communicate with the outside of the smoldering pool (20) respectively, the wall of the air inlet pipe (27) is provided with air outlet holes, and the air inlet pipe (27) is filled with flowing air , so as to cool the smoldering pool (20), part of the air in the air inlet pipe (27) enters the smoldering pool (20) to support combustion, and the air inlet pipe (27) is also connected to an air volume adjustment unit that adjusts the cooling air flow rate, and the combustion-supporting adjustment The mechanism is connected with the air inlet pipe (27), and cooperates with the air volume adjustment unit to adjust the amount of combustion-supporting air entering the smoldering pool (20). The smoldering device for rapid and low-temperature combustion of carbon powder in the biomass briquette fuel combustion device avoids coking and slagging of the fuel, reduces the volatilization of potassium, sodium and chloride elements, and reduces the problem of gas-solid pollutant emission and equipment sticking from the root cause of straw combustion. The ash can be used directly as farm fertilizer.

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...
