Abstract
The invention provides an automatic ash removing system for a biomass particle combustion furnace. The automatic ash removing system for the biomass particle combustion furnace comprises a furnace body, an ash tank, an air supply device, an ignition device and a feeding device, wherein the ash tank, the air supply device, the ignition device and the feeding device communicate with the furnace body. The furnace body comprises a hearth located at the bottom and a cylindrical furnace wall installed at the upper end of the hearth. A grate which can rotate in a reciprocating mode is arranged in the hearth. The grate is of the structure of a cylindrical hollow roller. A feeding port of the feeding device is formed in one side of the roller in the rotating direction. An ash outlet is formed in the other side of the roller in the rotating direction and is in a horn-shaped structure. The rotating direction of the roller is consistent with the conveying direction of biomass particles. A wind shield is arranged below the roller and connected between the feeding port and the ash outlet. The grate can rotate in a balance mode at a constant speed through a variable-frequency speed-adjustable motor and is not prone to coking or being damaged after high-temperature combustion, the heat efficiency is improved, and the fuel cost is reduced.
