Horizontally-feeding biomass particle combustion machine

Abstract

The invention provides a horizontally-feeding biomass particle combustion machine. According to the particle combustion machine, ash removal is easily achieved, and tempering danger is avoided. The horizontally-feeding biomass particle combustion machine comprises a hopper and a vaporizing chamber, wherein the hopper is connected with the vaporizing chamber through a feeding pipe; and the horizontally-feeding biomass particle combustion machine is characterized in that the feeding pipe is formed by sequentially connecting a first horizontal pipe, an anti-backfire pipe and a second horizontal pipe, and the first horizontal pipe is higher than the second horizontal pipe; the first horizontal pipe is connected with the bottom of the hopper, and a spiral feeding device driven by a motor is arranged in the first horizontal pipe; the second horizontal pipe is connected with the side of the bottom of the vaporizing chamber, the second horizontal pipe is provided with a feeding fan, and the blowing direction of the feeding fan faces the vaporizing chamber from the connecting position of the second horizontal pipe and the anti-backfire pipe; and an ash collecting concave portion is arranged on one side, far away from the second horizontal pipe, of the bottom of the vaporizing chamber. An ash removal door is arranged at the bottom of the ash collecting concave portion.

Description

technical field [0001] The invention belongs to the technical field of biomass energy utilization, and in particular relates to a biomass particle burner with horizontal feeding. Background technique [0002] Pellet burners usually have the following three feeding methods: 1. Upper feeding: The upper feeding burner is separated from the silo, and the risk of backfire is small, and accurate quantitative feeding can be guaranteed according to power requirements; the disadvantage is that the particles fall When it is unfavorable to the combustion layer, it may lead to an increase in incomplete combustion particles, so unstable combustion behavior, and the ash deposit needs to be removed regularly, even so will still produce slagging phenomenon; 2. Bottom feed: small combustion waves, the combustion process Continuous and stable, the disadvantage is that the later combustion time is long, and there is a risk of tempering; 3. Horizontal feeding: the combustion wave is small, the ...
