[0001] The utility model relates to the technical field of biomass processing equipment, in particular to an environmentally friendly dry slag discharger for a biomass power plant. Background Art

[0002] Biomass power plant refers to a factory that uses biomass to generate electricity. Biomass power plants usually use biomass such as wood chips, crop waste, etc. as raw materials, and convert them into biogas or biofuels through fermentation, gasification or other technologies to generate electricity. In this process, the residues generated include solid residues and ash residues, which need to be treated. Failure to treat the residues in time will have a certain impact on the environment and is not environmentally friendly.

[0003] At present, dry slag dischargers play a key role in biomass power plants. They are used to process and remove solid residues or ash produced during the power generation process.
