Fire grate for high-efficiency biomass burning furnace

Abstract

The invention relates to a fire grate for a high-efficiency biomass burning furnace, and belongs to components on burning furnaces. The fire grate mainly comprises a circular fence and a positioning cylinder (1) which are combined vertically, wherein grate bars (2) forming the circular fence are commercially available steel bars which have thread shapes; the plurality of grate bars (2) are arranged and overlapped on a cylinder frame (3) of which one inner side is provided with an inverse taper together; the grate bars (2) are closely contacted with each other in pairs in a gapless way; and the centre of the lower part of the circular fence is connected with a deceleration transmission mechanism (5) through a rotating shaft (4). The fire grate can be effectively applied to a biomass burning furnace, has an effect of blocking a biomass fuel, and is low in production and processing cost, ash blockage is avoided, and oxygen is supplied smoothly.

Description

technical field [0001] The invention relates to a component on a combustion furnace, in particular to a fire grate for a high-efficiency biomass combustion furnace. Background technique [0002] In existing stoves, the fire grate is a component that carries coal fuel, facilitates the removal of coal slag, and provides oxygen for the combustion of coal fuel. Usually in the shape of a fence, the bars that make up the fence are usually high temperature resistant, and there is a certain distance between the bars. [0003] With the price of coal, oil, and natural gas rising and the reserves declining, energy shortages and environmental pollution becoming more and more serious, people began to look for new energy sources to replace traditional energy sources. Later, it was discovered that biomass energy, as a renewable energy source, is very rich in resources and has the characteristics of low carbon content. In addition, it absorbs a large amount of carbon dioxide during its gro...

Problems solved by technology

Yet once there is this gap, there is the possibility that the biomass fuel will fall directly without hindrance.

If the steel plate is used to directly drill the densely distributed inclined holes or the inclined hole plate is manufactured by the sanding process, it can partially block the effect of biomass fuel, but the production and processing cost is quite high
