Combustor for combusting biomass particle fuels

Abstract

The invention provides a combustor for combusting biomass particle fuels, and belongs to the technical field of biomass combustion equipment. The combustor comprises a work bin, a combustion chamber positioned below the work bin, an equipment box fixed and communicating with the side wall of the back end of the combustion chamber, an unloading system, a combustion system, an air supply system andan ignition system; the unloading system comprises an unloading separation plate, an unloading driving connecting rod, an unloading driving flywheel, an unloading driving motor and an unloading travelswitch connected in sequence; the combustion system comprises a fire grate bracket, a fixed fire grate, and a movable fire grate, a fire grate driving connecting rod, a fire grate driving flywheel, afire grate driving motor and a fire grate travel switch, which are connected in sequence; the air supply system comprises a primary fan, a secondary fan, a secondary air pipe and two secondary air cavities; and the ignition system comprises an ignition fan, an igniter and an ignition air pipe. In the combustor, through classification combustion of fuels, the combustion is more sufficient, the pollutant emission is low, the automation degree is high, the operation is convenient, and such problems as frequent manual loading and insufficient combustion are solved.

Description

technical field [0001] The invention relates to a burner for burning biomass particle fuel, which belongs to the technical field of biomass burning equipment. Background technique [0002] At this stage, the total amount of heating energy used in rural buildings is large, the utilization efficiency is low, and the indoor thermal environment is generally poor. From the perspective of energy structure, the proportion of commercial energy consumption is high, and coal accounts for about 75% of heating energy consumption (Building Energy Conservation Research Center of Tsinghua University. China Building Energy Conservation Development Annual Research Report 2016. Beijing: China Architecture and Building Press, 2016). The thermal efficiency of coal-fired heating furnaces widely used in rural areas is only 30%-40%. The burning of a large amount of loose coal in these low-efficiency and high-emission coal furnaces has caused huge energy waste and serious environmental pollution. ...
