Abstract

A chain-type boiler backfire protection feed apparatus for biomass combustion relates to a chain-type boiler backfire protection feed apparatus. The invention resolves the problem in prior chain-type boiler in direct biomass combustion that the biomass might be burned in buckets due to backfire caused by high biomass combustion speed. The invention comprises a biomass lower bucket (1), a biomass upper bucket (2), an articulate vane (3) and a motor (4); wherein, the biomass upper bucket (2) is arranged on the left end face of the upper-end of the biomass lower bucket (1); moreover, the biomass lower bucket (1) communicates with the biomass upper bucket (2); the articulate vane (3) reaches the biomass lower bucket (1) and the biomass upper bucket (2) through the left end face on the lower-end of the biomass upper bucket (2); the left end of the articulate vane (3) is linked to the motor (4). The invention simultaneously utilizes the multi-stage with feed the biomass upper bucket, the biomass lower bucket and the articulate vane, so as to avoid backfire due to high combustion speed for biomass fuels, so that the biomass is burned in the buckets; therefore, the invention can guarantee the safety of boilers.

Description

technical field [0001] The invention relates to an anti-tempering feeding device for a chain boiler, which belongs to the technical field of industrial boilers. Background technique [0002] With the rising prices of fossil fuels such as oil and natural gas, the development of renewable energy has become a global hot issue and an inevitable choice for the development of sustainable energy. Compared with fossil energy, biomass energy has great advantages. Biomass energy CO 2 The net emission is zero, which can effectively alleviate the greenhouse effect. Its sulfur and nitrogen contents are very low, and its ash content is also very small. Therefore, the development and utilization of biomass energy is an effective way to relieve energy and environmental pressure and establish a sustainable energy system. measure. In order to save energy and reduce emissions, small thermal power units using chain grates with high energy consumption, low efficiency and high pollution will be...
