Eccentric furnace pipe type layer-by-layer combustion biomass boiler

Abstract

The invention relates to an eccentric furnace pipe type layer-by-layer combustion biomass boiler, comprising a base and a boiler barrel, wherein the boiler barrel is arranged on the base, a furnace pipe is arranged in the boiler barrel, the center of the furnace pipe is deviated from the center of the boiler barrel, a space formed by the furnace pipe and the boiler barrel is a water cavity, the upper end of the furnace pipe is provided with an upper smoke collecting box which comprises a protruding boss, the boss is provided with a plurality of main smoke pipes, one ends of the main smoke pipes are communicated with the upper smoke collecting box, the other ends of the main smoke pipes are communicated with a lower smoke collecting box which is communicated with an auxiliary machine, and the boiler barrel is also provided with a layer-by-layer combustion type combustion chamber in which bunkers are combusted layer by layer from bottom to top. The eccentric furnace pipe type layer-by-layer combustion biomass boiler adopts an eccentric type furnace pipe structure, the furnace pipe is inclined to one side of the boiler barrel, so that banker feeding is more convenient, and the thickness of a water jacket interlayer at the feed port of the boiler is reduced to more than 50%.

Description

technical field [0001] The invention relates to a biomass boiler, in particular to an eccentric furnace type layer-by-layer combustion biomass boiler. Background technique [0002] As we all know, biomass is waste from agricultural and forestry production. If it is discarded and incinerated at will, it will seriously pollute the environment. Using biomass to incinerate in a boiler, the steam generated is used for power generation or steam supply, which has the potential to save energy and reduce environmental pollution. Social benefits, but also good economic benefits. [0003] With the sharp decline of non-renewable energy sources such as oil, coal, natural gas and ocean ice, and the rising prices, as well as the increasing awareness of environmental protection of human beings, what used to be regarded as "chicken ribs" is tasteless and discarded Unfortunately, the aforementioned biofuels have received unprecedented attention. According to the statistics of my country's a...
