Problems solved by technology
[0004] The flue gas of the above-mentioned heater fuel is directly discharged after burning, and the heat loss is large. The air is blown into the hollow interlayer between the furnace body and the furnace, which reduces the temperature of the combustion flame in the furnace, resulting in insufficient combustion, high CO emissions, and high combustion efficiency. At the same time, the heat is gathered in the interlayer of the furnace body, which is easy to generate eddy currents, which will cause the local temperature of the furnace body to be too high, resulting in deformation of the furnace body
In addition, the above-mentioned air heater needs an external power supply during operation, and is not suitable for the wild or remote areas without electricity.

A self-powered warm air furnace comprises a furnace body, wherein a hearth is formed in the furnace body; an air supply passage with an air inlet and an air outlet is formed in the upper portion of the furnace body; an annular flue which is connected with the hearth is sleeved in the air supply passage; a smoke outlet is formed in the flue; a plurality of thermoelectric modules are arranged between the air supply passage and the flue; and an air blower is arranged at the air inlet and is driven by the thermoelectric modules. According to the self-powered warm air furnace, power is generated through the thermoelectric modules by using temperature difference between the flue and the air supply passage, and drives the air blower to work; air is fed to a cold end for cooling the thermoelectric modules in the air supply passage by the air blower; and the air which is in heat exchange in the air supply passage is fed in an indoor environment for heating. The self-powered warm air furnace is high in heating efficiency, low in using and maintenance cost, stable and reliable in performance and high in power generation efficiency and power. By using the self-powered warm air furnace, the temperature raising speed in the indoor environment is high, and the power can be provided for the air blower; and moreover, the self-powered warm air furnace is suitable for camping tents or high and cold regions in winters.
Description
technical field [0001] The invention relates to a high-efficiency air heater, in particular to a self-powered air heater. Background technique [0002] Existing coal-fired stoves are composed of a furnace base, a furnace grate, a furnace, a furnace body and a burner basin, etc. The heat insulation material is filled between the furnace body and the furnace, and the temperature in the furnace and the furnace mouth is relatively high, which is conducive to burning Water is used for cooking, but the heat insulation layer is filled between the furnace body and the hearth, which hinders the heat transfer and radiation in the furnace. The heating mainly depends on the heat release from the chimney. The inertial force and draft force of the high-temperature flue gas exiting the furnace are quickly drawn away by the chimney, and most of the heat generated by combustion is brought into the external environment by the flue gas, which reduces the utilization rate of combustion heat and...
