Biomass fuel burning equipment and burning method thereof

Abstract

The invention relates to biomass fuel burning equipment and a burning method thereof. The biomass fuel burning equipment comprises a burning furnace and a blowing device, a rotatable fire grate and a fire grate rotation driving device are arranged in the burning furnace, the fire grate comprises a circular bottom rotating plate, a plurality of groups of funnel caps, fireproof clay layers, an ash pipe and a sealing plate, wherein the funnel caps are arranged above the bottom rotating plate, the fireproof clay layers are paved on the funnel caps, the ash pipe is connected to the circular center of the bottom rotating plate, and the sealing plate is fixed at the outer edge of the bottom rotating plate. The biomass fuel burning equipment and the burning method thereof are applicable to assorted boilers, water heaters, air heaters and the like, and are used for burning biomass energy, fuel is uniformly arranged and suspended on the fire grate to burn after entering the burning furnace, and burning efficiency is high. Ash after power burning can be discharged completely from the ash pipe, an air inlet system is prevented from being blocked by the ash during burning, and the ash is collected and recycled, is convenient to clean and free of affection on the environment.

Description

technical field [0001] The invention relates to the technical field of combustion stoves, in particular to a combustion device for burning biomass fuels such as sawdust, straw, chaff, palm fruit bunches, agricultural and forestry waste, and a combustion method for the device. Background technique [0002] The grate is a part of the combustion equipment used to pile up fuel and make it burn effectively. The traditional grate carries block fuel, and there are usually strip grilles on the grate to facilitate the discharge of cinders and provide fuel for combustion. Oxygen, the traditional grate cannot carry powdered fuel or biomass energy, and it is easy to cause problems such as ash clogging and poor oxygen supply. [0003] In order to solve the above problems, the Chinese invention patent application (application number: 201210342648.8) discloses a new type of biomass filtration rotary air-cooled grate system, including a rotating shaft, a grate chassis, a chassis bracket, a ...

AI Technical Summary

Problems solved by technology

[0004] This kind of rotary air-cooled grate system can make the powder evenly distributed on the grate for combustion to a certain extent, but it has the following disadvantages. First, the ash after the fuel is burned on the grate is not easy to fall, and After that, it falls directly below the grate, so it cannot be cleaned in a centralized manner, and the dust will fly and easily pollute the environment duri
