Biomass combustion special furnace

Abstract

The invention relates to a novel biomass combustion special furnace arch taking biomass materials as raw materials and belonging to the technical field of combustion furnaces. The novel biomass combustion special furnace arch has a structure that a furnace body is internally provided with a front arch, a middle arch and a rear arch, wherein a feed zone is formed between the front arch and a hopper, a volatilization oxidation reduction zone is formed between the front arch and the middle arch, and a main combustion zone is formed between the middle arch and the rear arch; the shape of the rear arch is a fold line structure, and the shape of the front section of the rear arch is a level straight line structure; the middle arch is positioned between the front arch and the rear arch and in a single row wall body structure, the upper end of the middle arch is connected with a water containing boiler, the middle of the lower end of the middle arch is provided with a combustion passage, and the middle section of the inner side of the middle arch is provided with a bump which is positioned at the outer side above the rear arch. The invention relates to the novel biomass combustion special furnace arch which is beneficial to the sufficient combustion of biomass fuel, has long flame flow path, high heat efficiency, energy saving, smoke elimination, good environmental protection property, high temperature raising speed of water inside a the water containing boiler, and the like.

Description

technical field [0001] The invention relates to the technical field of combustion furnaces, in particular to a new type of furnace arch dedicated to biomass combustion using biomass materials as raw materials. Background technique [0002] In today's energy shortage, the utilization of biomass fuels has a very broad prospect. There are a large number of biomass fuels in the vast rural areas, but due to the lack of new and efficient combustion devices matching with biomass fuels, it is impossible to use biomass fuels More extensive utilization wastes a lot of precious biological resources, so it is necessary to transform coal-fired boilers and develop a new type of special furnace arch for biomass combustion to adapt to the use of biomass fuel combustion. Contents of the invention [0003] The purpose of the present invention is to improve the design of the furnace structure of the bedroom boiler according to the characteristics of biomass fuel combustion; to develop a boil...
