Abstract

The invention proposes a burner for burning biomass particle fuel, which belongs to the technical field of biomass burning equipment. It includes a material box, a combustion chamber located below the material box, an equipment box fixed and communicated with the rear end side wall of the combustion chamber, a feeding system, a combustion system, an air supply system and an ignition system; the feeding system includes successively connected feeding compartments Plate, blanking drive connecting rod, blanking driving flywheel, blanking driving motor and blanking stroke switch; combustion system includes grate support, fixed grate, movable grate connected in sequence, grate driving connecting rod, and grate driving Flywheel, grate drive motor and grate travel switch; air supply system includes primary fan, secondary fan, secondary air pipe and two secondary air chambers; ignition system includes ignition fan, igniter and ignition air pipe. Through the staged combustion of fuel, the burner has more complete combustion, low pollutant emission, high degree of automation, and easy operation, which solves the problems of frequent manual feeding and insufficient combustion.

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. ...
