Technical Field
The utility model relates to a living beings pellet fuel field specifically is a biomass fuel burning heat transfer device.
Background
Combustion furnaces are widely used in heat exchange devices at present, with biomass combustion furnace equipment being the most common. The biomass combustion furnace is an energy-saving and environment-friendly heating tool, can be used for the requirements of water heating, cooking, heating and the like, and has a very wide application field. The biomass particles generate hot gas after being combusted in the hearth, and if fine dust doped in the hot gas is not removed, the fine dust can be brought into the heat exchanger by the hot gas flow, so that the service life and the heat exchange efficiency of the heat exchanger are influenced. Meanwhile, the biomass particles are not completely combusted, so that the utilization rate of the biomass particles is not high, and the phenomenon is caused by the following reasons: the biomass particles are not completely combusted; the oxygen supply in the hearth is insufficient.
