Abstract：
 A kind of heat-blow device which burns biomass composes of circulation fluidized bed boiler furnace that burn biomass, biomass-feed system, air-water heat exchanger, circulation fan, thermodynamic instrument and so on. Its basic characteristic is: the circulation fluidized bed boiler furnace's main fuel is biomass such as agricultural and forestry waste materials, and its mediator is organic heat carrier or water; the front tank walls of the boiler furnace is water wall, Directional Buttons are set on the all Air Ventilation Board, and the Directional Buttons are laid rotatably; the speed of the furnace tank empty bed is up rated. The characteristic of the device lays yet, to set secondary heat exchanging system, to adapt converter technique and heated air recycling technique after drying and so on, which makes sure hot-air flux and temperature are stable. This invention has the merits of energy conservation and environmental protection. We can control the hot air temperature exactly. The wind rate and wind temperature are particularly stable, and when drying agricultural and forestry things, food substance and other substance needing hot-wind drying under low temperature, it is very stable, economical and environmental.
