Ash discharge structure of solid particle fuel stove

Abstract

The invention discloses an ash discharge structure of a solid particle fuel stove. The ash discharge structure of the solid particle fuel stove comprises a stove bottom (1), a combustor (2), a bottom box (3) and an ash discharge device. The combustor (2) is located in a hearth (5) of the stove and installed on the stove bottom (1). An ash outlet (22) is formed in the lower portion of the combustor (2). An ash discharge and air inlet hole (11) is formed in the position, corresponding to the ash outlet (22) of the combustor (2), of the stove bottom (1). The bottom box (3) is located below the stove bottom (1) and installed on the stove bottom (1), and an inner cavity of the bottom box (3) is communicated with the ash discharge and air inlet hole (11) of the stove bottom (1). The ash discharge device comprises a fire grate (41) and a fire grate shaking device, the fire grate (41) is a separation net capable of leaking ash and stopping material, and the fire grate (41) is movably installed on the stove bottom (1) or the bottom box (3), located in the bottom box (3) and located below the ash discharge and air inlet hole (11). The fire grate shaking device is connected between the bottom box (3) and the fire grate (41) and can drive the fire grate (41) to vibrate or shake. According to the ash discharge structure of the solid particle fuel stove, ash can be discharged conveniently, and fuel can be prevented from coking.

Description

technical field [0001] The invention relates to a stove structure, in particular to an ash discharge structure for a solid particle fuel stove. Background technique [0002] Solid pellet fuel mainly includes biomass pellet fuel, mineral pellet fuel, etc. [0003] Biomass pellet fuel is referred to as biomass fuel for short. Biomass fuel is mostly agricultural waste and wood waste (stem crops, peanut shells, bark, sawdust and solid waste (furfural residue, edible fungus residue, etc.)) after processing Produces lumps (mainly cylinders) of fuel. Biomass fuel has the following characteristics: high calorific value, no corrosion of boilers, no air pollution, clean sanitation, very little ash, and ash is a recyclable, profitable and renewable energy source. [0004] Therefore, biomass fuel is an ideal fuel for people's daily production and life, and it is the development direction of environmental protection and sustainable energy; however, the current biomass fuel stoves have ...

AI Technical Summary

Problems solved by technology

[0005] 1. Natural ash, poor ash, affecting firepower, low combustion efficiency;

[0006] 2. Unsmooth ash discharge will easily stop the movement of fuel and dust for a long time, and coke at high temperature. In severe cases, the furnace needs to be shut down for cleaning, resulting in the failure of smooth combustion
