Biomass particle combustion boiler system capable of realizing automatic control

Abstract

The invention discloses a biomass particle combustion boiler system capable of realizing automatic control. The biomass particle combustion boiler system comprises a PLC control box and a material feeding port; the material feeding port is connected with an elevator; the elevator is connected with a bin; a discharge pipe is arranged on the bin, and is connected with a boiler; and an unloader is arranged in the bin. The biomass particle combustion boiler system further comprises a purifying fan and an oxygen replenishing fan; and a temperature sensor and an oxygen content testing sensor are further arranged in the boiler. Oxygen-contained gas is delivered into the boiler through the oxygen replenishing fan, so that the oxygen content in the boiler is increased, and biomass particles can be fully combusted in the boiler without producing black smoke, so that the purposes of workshop purification and safety production are achieved; sucked gas mixed with dust is delivered into the boiler through the purifying fan; on the one hand, the workshop working environment is purified; and on the other hand, the raw material waste is prevented; and the oxygen replenishing fan and the unloader control the rotating speed of a variable frequency fan by the PLC control box according to received detecting signals so as to control the unloading speed to adjust the oxygen content in the boiler.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to an automatically controllable biomass particle combustion boiler system. Background technique [0002] When the existing biomass pellets are put into the boiler for combustion, the boiler burns for a long time, and the internal oxygen content decreases, resulting in insufficient combustion of the biomass pellets, which in turn produces a large amount of black smoke, which permeates the entire workshop and seriously affects the safety of the entire workshop. In the production environment, during the combustion process, the flame in the boiler will spread along the discharge end to the silo, and tempering will occur. In addition, a large amount of dust will be generated due to factors such as collisions when the raw materials are put into the feed port. Dust contains a large amount of raw materials, resulting in waste of raw materials, and because of the diffuse dust...

In addition, a large amount of dust will be generated due to factors such as collisions when the raw materials are put into the feed port. The dust contains a large amount of raw materials, resulting in a waste of raw materials, and because of the diffuse dust, the working environment of the entire production workshop is poor, which seriously affects the health of operators
