Waste incineration biomass steam boiler

Abstract

This utility model discloses a biomass steam boiler for waste incineration, including a combustion chamber and a furnace shell. Beneficial effects: This utility model employs a feeding hopper, a tilting plate, and a roller crushing mechanism. When incinerating biomass waste, the waste can be fed into the feeding hopper. The waste is then crushed by the roller crushing mechanism into waste particles. These particles then enter the feeding hopper. A servo motor drives a shaft to rotate, which in turn rotates the tilting plate, carrying the waste particles between the tilting plates into the combustion chamber, completing the quantitative feeding and improving combustion stability. Simultaneously, the roller crushing mechanism crushes the waste, avoiding the problem of incomplete combustion of some larger waste materials, thus improving the combustion efficiency and utilization rate of the waste. Operators can adjust the rotation speed of the tilting plate via the servo motor, thereby adjusting the feeding speed. This flexible and convenient adjustment further improves work efficiency and ease of use.
