Biomass particle burner capable of improving burning rate

Abstract

The invention relates to the technical field of burning equipment, and discloses a biomass particle burner capable of improving the burning rate. The biomass particle burner comprises an equipment body, wherein a fan, an air box and a burning furnace are sequentially installed at the bottom of the equipment body; a feeding hopper is fixedly installed on the upper portion of the equipment body; anda feeding screw is fixedly connected to the bottom of the feeding hopper. Through the arrangement of a cleaning plate and an air supply device, air rushing to fan blades from the air box drives the cleaning plate to rotate, burning ash above a metal filter screen is smashed, the purpose of smashing the burning ash before coking is achieved, and coking is prevented; the air passing through a rotary joint and a hollow shaft enters an air supply channel, a wedge block is jacked open under the air pressure for ventilation, the smashed ash is blown to a fire spraying opening through wind power forsecondary burning, and coking is prevented while the burning efficiency is improved; and the wedge block is in a closed state under the action of a spring under the non-ventilation condition, and thesituation that burning particles, impurities and the like enter the air supply channel, and consequently the air supply channel is blocked is avoided.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a biomass particle burner with improved combustion rate. Background technique [0002] The burner is a high-efficiency and energy-saving biomass combustion equipment developed mainly for industrial furnaces, coating, drying, die-casting and other industries. This series of products uses biomass particles as fuel and adopts semi-gasification composite combustion technology. It has a reasonable structure and is fully automatic. Intelligent control. At present, the burners used in the market are mainly screw-type feeding methods. The fuel in the hopper is transported to the combustion chamber through the screw for full combustion. [0003] The existing biomass pellet burners still have the following deficiencies in actual use: First, because the traditional biomass pellet burners all use screw feeders for feeding, and the burner needs to enter at least about one-fifth o...

AI Technical Summary

Problems solved by technology

[0003] The existing biomass pellet burners still have the following deficiencies in actual use: First, because the traditional biomass pellet burners all use screw feeders for feeding, and the burner needs to enter at least about one-fifth of the The ignition work can only be carried out with a certain amount of fuel, which will lead to the accumulation of combustion particles at the bottom of the combustion furnace, resulting in insufficient combustion, and the used biomass pellet fuel contains oil, sugar, and a small amount of minerals in the wood and straw materials. During the combustion process, it will be severely coked, forming slag blockage, blocking the furnace, and causing the biomass burner to fail to operate normally; secondly, after the biomass particles are coked, the grate will be blocked, affecting the air supply, and the heat will accumulate due to the coke blocks blocking the grate At the grate position, the higher the temperature, the easier it is to coke. If it is not treated, it will cause flameout and unexpected production stoppage. Therefore, it is necessary to open the grate opening to clean the furnace after a period of time, because the coke blocks are glued to the furnace after cooling. , it is difficult to clean, and it is easy to cause damage to the furnace body
