Abstract

The invention discloses a biomass hot blast stove. The biomass hot blast stove comprises a hot blast stove body and an emergency vent chimney (12). The hot blast stove body comprises a charging port (3), a fire grate (2), an ash pit (1), a front combustor (5), a rear combustor (10), a primary settling chamber (8), a primary air-cooled beam (6), a secondary air-cooled beam (9) and a smoke window (7). The emergency vent chimney (12) comprises a flame retarding plate (14), a tertiary settling chamber (16), a tertiary air-cooled port (17), an emergency vent chimney outlet (15) and an emergency vent smoke outlet (13). The upper portion of the front combustor (5) is communicated with the upper portion of the primary settling chamber (8) through the smoke window (7). The lower portion of the rear combustor (10) is communicated with the lower portion of the primary settling chamber (8). The emergency vent chimney (12) is connected with the rear combustor (10). High-temperature smoke produced by the front combustor (5) in the burning process flows in the hot blast stove body circuitously. Through the biomass hot blast stove, secondary combustion is achieved, fuel can be fully combusted, the thermal efficiency is high, and the pollution is little.

Description

technical field [0001] The invention belongs to the field of combustion equipment, and in particular relates to a biomass hot blast stove. Background technique [0002] Biomass shaped fuel briquettes are produced from biomass after collection, crushing, drying and pressing. In the production process, a technical key of raw material drying is to reduce the moisture content of raw materials by 8% to 12%. The current common drying method is to use the hot air generated by the biomass hot stove to directly heat and dry the biomass raw materials. At this stage, most of the biomass hot stoves in my country use biomass briquettes as fuel. There are many kinds of biomass briquettes, which generally have the characteristics of high ash content, rapid combustion, low combustion value, and easy coking. Therefore, improving combustion efficiency, fully removing dust, and reducing environmental pollution are two indicators that must be achieved in the development of bio-combustion tec...
