Biomass fuel hot-blast stove hearth structure

Abstract

The invention discloses a biomass fuel hot-blast stove hearth structure. The structure comprises a base, wherein an air blower is fixedly connected to the upper surface of the base, an air supply pipeis fixedly connected to the side face of the air blower, a fixing frame is fixedly connected to the upper surface of the base, a hot-blast stove is arranged on the inner wall of the fixing frame, a smoke guide pipe is fixedly connected to the upper surface of the hot-blast stove, a hot air guide pipe is arranged on the upper surface of the hot-blast stove, and a fuel funnel is arranged on the side face of the hot-blast stove. According to the biomass fuel hot-blast stove hearth structure, air can be generated by arranging the air blower, the air blown by the air blower can be conveyed into amain hearth of the hot-blast stove by arranging the air supply pipe, then combustion air distribution of the main hearth is uniform, biomass fuel can be accumulated by arranging a material collectingnet, the main hearth and a sub hearth are arranged, a combustion area of the biomass fuel is increased, and the biomass fuel is combusted more sufficiently in the hearth, so that the effect that the fuel can be combusted completely is achieved.

Description

technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a hearth structure of a biomass fuel hot blast stove. Background technique [0002] Biomass refers to various organisms produced through photosynthesis by using the atmosphere, water, land, etc., that is, all living organic substances that can grow are commonly referred to as biomass, which includes plants, animals and microorganisms. Biomass briquette fuel processing A technical key is to reduce the moisture content of raw materials to 8% to 12%. The most widely used drying method is: using a vertical biomass hot stove to directly heat biomass raw materials, such as bark, waste wood, wood chips, straw Wait. [0003] However, biomass generally has the characteristics of high moisture content, large fuel size changes, and high ash content. The air distribution in the furnace is uneven, so that the fuel cannot be completely burned. At present, the furnace structure of the...

Problems solved by technology

[0003] However, biomass generally has the characteristics of high moisture content, large fuel size changes, and high ash content. The air distribution in the furnace is uneven, so that the fuel cannot be completely burned. At present, the furnace structure of the hot blast stove is very simple. Generally, there is only one independent furnace structure. The combustion process is completed in one hearth, this kind of hot air stove is only suitable for burning bark, waste wood
