Biomass granule material combustor

Abstract

The invention discloses a biomass granule burner, comprising a feeding system, an air supplying system and a burning system. The feeding system comprises a feeding pipe, a feeding auger installed in the feeding pipe, a reducing motor and a feed box; the air supplying system comprises a blower and air pipes; the feeding pipes are positioned in the upper part of the air pipe and arranged in a co-rotating parallel way, the burning system is provided with a bellows, as the top surface of the bellows, a burning material disc is fixedly connected to the top of the bellows, and provided with an air vent, the bellows is connected to the air pipes of the air supplying system, while the burning material disc is fixedly connected to the feeding pipe of the feeding system, and a connecting flange thatcan be connected to a heating boiler is arranged between the air pipes and the feeding pipe. The burning system of the bellows structure has simple structure and low production cost; since the burning material disc is positioned on the bellows, the air is evenly distributed, with high burning efficiency and thermal efficiency and good environmental protection effect; the feeding pipe in the bellows is opened with the air vent, the air pressure in the bellows can prevent the fume in the burning material disc from entering the feed box, thus settling the smoking problem of the feed box.

Description

technical field [0001] The invention relates to a burner, in particular to a burner for burning biomass pellets. Background technique [0002] Biomass pellets are generally made by crushing and pressing crop stalks. At present, rural crop straw is generally returned to the field by direct burning in the field. Direct burning and returning to the field will cause great damage to the ecological environment, pollute the air, affect flight safety, and cause a waste of resources. Existing biomass fuel devices can be used for heating, heating, and gas production, but generally have complex structures, low combustion efficiency, and unstable performance. [0003] The Chinese utility model patent with the publication number CN2684025Y discloses a biomass particle burner, which includes a shell with an air preheating air duct on the shell, a rotating core installed in the shell, and a sleeve connected to the rotating core mounted on the shell On the top, a screw feeder is installed...

AI Technical Summary

Problems solved by technology

This kind of biomass particle burner has complex structure and high cost, and the rotating core of the burner is easy to deposit carbon, and the combustion flue gas will flow back from the sleeve installed with the screw feeder to the feed inlet, and then come out from the feed inlet. Exhaust smoke, pollute the environment, not easy to popularize and use
