Biomass particle combustion furnace

Abstract

The present invention relates to the technical field of combustion equipment, in particular to a biomass particle combustion furnace. A combustion chamber is internally provided with two fire grates,and rotating shafts of the two fire grates respectively extend out of a furnace body and are connected with a fire grate transmission mechanism. An ash clearing auger is arranged in an ash falling bin, and one end of an auger shaft of the ash clearing auger extends out of the furnace body and is connected with an ash clearing transmission mechanism. An ash outlet of the ash clearing auger is arranged on the other side away from the furnace body and a feeding device. A storage bin of the feeding device is arranged at the side upper part of the combustion bin, and the storage bin is arranged above an upper feeding auger. The discharge end of a lower feeding auger is arranged at the side upper part of the combustion bin in the furnace body, and the upper feeding auger and the lower feeding auger are connected with a feeding transmission mechanism. The grate rotating with fixed axis realizes dynamic combustion and solves the slagging problem. The ash removal auger and the synchronous transmission mechanism for feeding and ash removal can solve the problem that accumulated ash cannot be cleaned in time.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a biomass particle combustion stove. Background technique [0002] As the country pays more and more attention to environmental protection, and vigorously promotes the development and utilization of biomass energy. Make today's biomass pellet fuel widely used in actual production and life. Biomass pellet fuel has the advantages of easy storage, convenient transportation, clean environmental protection and high combustion efficiency, and is one of the main directions for the development and utilization of biomass energy. [0003] However, there are the following problems when using biological pellets as fuel: [0004] Problem 1: The biomass pellet fuel made of pressed plant stalks has high sugar content, and slagging often occurs in the furnace during combustion. When the fuel burns, slagging in the furnace will block the ventilation gap between the fuel layers, wh...

Problems solved by technology

[0004] Problem 1: The biomass pellet fuel made of pressed plant stalks has high sugar content, and slagging often occurs in the furnace during combustion

When fuel burns, slagging in the furnace will block the ventilation gap between the fuel layers, which will not only affect the normal combustion of fuel in the furnace and cause waste of fuel, but also seriously affect the life of the combustion equipment

[0005] Problem 2: The grates of traditional small and medium-sized biomass pellet burning stoves are mostly fixed, and the ash often needs to be manually removed regularly; if the accumulated ash is not cleaned in time, it will affect the combustion performance of the stove; Long-term excessive accumulation will affect the service life of the stove
