Biomass particle combustor capable of automatically removing slag

Abstract

The invention relates to a biomass particle combustor capable of automatically removing slag reasonable in structural design, low in manufacturing cost and capable of greatly improving the combustion efficiency. The biomass particle combustor comprises a feeding system, a slag removing system, an air supply system and a combustion system, wherein the feeding system comprises a speed reducing motor, a material box, a material pipe and a feeding auger installed in the material pipe, the speed reducing motor drives the feeding auger to perform rotary feeding in the material pipe, the material pipe comprises a material inlet and a material outlet, and the material inlet is designed at the bottom of the material box to be in communicated connection with the material box. The air supply system comprises a fan, an air delivery pipe, an outer air box and an inner air box, wherein one end of the air delivery pipe is connected with the fan, the other end of the air delivery pipe is connected with the outer air box, and the inner air box is welded, installed and fixed inside the outer air box. The combustion system comprises an installing rack, a combustion pipe and a flame outlet guiding pipe. The slag removing system comprises a slag removing motor, a slag removing gear, a positioning pipe, a connecting shaft installed in the positioning pipe and a slag removing rod.

Description

technical field [0001] The invention relates to a burner, in particular to a biomass particle burner with automatic slag removal. Background technique [0002] In recent years, with the promotion and application of biomass fuel particles at home and abroad, biomass pellet burners with various structures are emerging. Biomass burners are more and more popular due to their advantages of energy saving, environmental protection, and low fuel prices. The replacement of ordinary coal-fired boilers. Existing burners usually have a basin-type interlayer structure. The interlayer is an air chamber and an air inlet is made. An air distribution hole is made on the bottom and wall of the inner layer of the burner. The burner is connected to a The screw feeder at the lower part drives the fuel into the burner for combustion, thereby generating high temperature for heating the boiler, etc., to realize heat supply.

AI Technical Summary

Problems solved by technology

[0003] However, there are still some deficiencies in the existing burners, which are specifically reflected in the following: most of the biomass in my country uses straw as raw material, and it is easy to produce coking on the inner surface of the burner during the high-temperature combustion process. If there is too much coking, the It will affect the combustion of biomass fuel, so it needs to be cleaned regularly; and the structure of the existing burner is complex, the combustion efficiency is low, the performance is not stable, and the coke, ash and other sundries produced after combustion cannot be cleaned in time. Some improperly designed burners are prone to tempering or insufficient fuel combustion, which bring great hidden dangers to the work of the burner and have a great impact on the continuity of heating.
