Multi-ash biomass energy granular fuel combustor

Abstract

The invention discloses a multi-ash biomass energy granular fuel combustor, which comprises a feeding motor, a storage chamber, a distributor, a primary feeding auger, a chain wheel transmission system, a left auger feeder, a right auger feeder, a secondary air box, a combustion cup, a fan, a flame detector and an ignitor, wherein the combustion cup is a bucket-shaped cavity; the upper part of the cavity is open; an air box is arranged in the middle of the cavity; primary air holes for supplying air to a fuel are uniformly distributed on two side walls of the air box and four walls of the combustion cup; the secondary air box is an oblong box body; one side of the secondary air box is connected with the fan through a connecting flange, and the other side of the secondary air box is connected with a combustion cup hood; secondary air holes are uniformly distributed on the side wall of the secondary air box; and the left auger feeder and the right auger feeder are arranged at the bottom of the combustion cup and are provided with augers with opposite rotation directions and poking sheets at the end of the combustion cup. According to the rational combustion mechanism of the invention, high-power, high-efficiency and automatic continuous combustion of the multi-ash biomass energy granular fuel combustor are realized, and the problems of multi-ash biomass coking, slagging, ash discharge and slag discharge are effectively solved.

Description

technical field [0001] The invention relates to a multi-ash biomass energy granular fuel burner, which belongs to the technical field of biological energy. Background technique [0002] With the continuous improvement of people's awareness of energy and environmental issues, energy conservation, emission reduction, consumption reduction, and environmental protection have attracted more and more attention. After coal, natural gas, oil and other fuels are burned, the resources are non-renewable, and the thermal efficiency is low, resulting in serious waste of resources, which does not conform to the general trend of energy saving and environmental protection. Strengthening the development and utilization of renewable energy is the only way to solve the increasingly serious energy and environmental problems, and it is also the only way for the sustainable development of human society. At present, countries all over the world are devoting themselves to the development of high-e...

AI Technical Summary

Problems solved by technology

[0003] my country is a large agricultural country, and has very rich biomass fuel energy, but due to the lack of good utilization methods, many fuels are burned directly, which not only does not make full use of heat energy, but also causes environmental pollution and wastes precious energy.

Although there are already some thermal energy utilization equipment for biomass fuel, there are generally incomplete combustion, low thermal efficiency, and residues after combustion are easy to coke or block in the equipment, so that the thermal energy equipment cannot work normally.
