Particle circulating burner for biomass gasification combustion

Abstract

The invention discloses a particle circulating burner for biomass gasification combustion. The particle circulating burner comprises a high-pressure fan, a cyclone cylinder shell and a gasifier shell,wherein a low-temperature gasification area is arranged inside the gasifier shell, and a gasification air duct is further arranged inside the gasifier shell. According to the particle circulating burner, the biomass low-temperature gasification area is connected with a cyclone combustion area, and the conveying link of biomass gasification gas is reduced, so that the heat dissipation loss is reduced, and the heat efficiency is improved; a cyclone combustion technology is used for the combustion of the biomass gasification gas, a cyclone nozzle is tangentially arranged on the cyclone cylindershell, and the biomass gasification gas rotates under the driving of cyclone air, so that the mixing disturbance of air and the biomass gasification gas is strengthened, and the combustion efficiencyof the biomass gasification gas is improved; and the combustion of the biomass gasification gas belongs to non-premixed combustion, and according to the cyclone combustion mode, flame fullness in a cyclone cylinder is good, and the heat load distribution is uniform.

[0002] Energy shortage and environmental pollution are the main problems restricting my country's economic development. Therefore, improving energy utilization and realizing clean energy utilization is an important way to solve the above problems. Biomass energy is an important part of renewable energy. The efficient development of biomass energy Utilization will play a very positive role in solving energy and ecological environment problems. Since the 1970s, all countries in the world, especially economically developed countries, have attached great importance to this, and actively carried out research on biomass energy application technology and achieved many research results. Among them, the application of biomass gasification technology has reached an industrial scale. The biomass energy burners currently on the market have low combustion efficiency, large heat loss, and poor thermal efficiency when they are in use.
