Biomass particle combustor

Abstract

The invention provides a biomass particle combustor. The biomass particle combustor comprises feeding equipment, combustion equipment and blast air supply equipment, wherein the feeding equipment comprises a material pipe; the combustion equipment comprises an inner fire outlet pipe and an outlet fire guide pipe; the blast air supply equipment comprises a blast pipe, an outer air box and an inner air box; the inner air box is arranged inside the outer air box, and the blast pipe is communicated with the outer air box and the inner air box; the material pipe penetrates through the inner air box to be communicated with the inner fire outlet pipe; the inner fire outlet pipe is arranged on the outer wall of the inner air box and penetrates through the outer air box, and vent holes are formed in the inner fire outlet pipe; the outlet fire guide pipe is fixed to the outside of the outer air box to sleeve the part, outside the outer air box, of the inner fire outlet pipe, and a gap is reserved between the outlet fire guide pipe and the inner fire outlet pipe and communicated with the outer air box. The biomass particle combustor is reasonable in structural design, low in cost and high in combustion efficiency.

Description

technical field [0001] The invention relates to the field of biofuels, in particular to a biomass particle burner. 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. [0003] However, there are still some deficiencies in the existing burners, which are s...

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.
