Heating system with temperature difference driving air inlet device

Abstract

The invention discloses a heating system with a temperature difference driving air inlet device. The temperature difference driving air inlet device comprises a temperature difference driving system and a fan driven by the system, wherein air or premixed gas required by combustion is driven by the fan to enter a combustion area of the heating system, the high-temperature end of the temperature difference driving system is located in the combustion area, and the low-temperature end is located in an air inlet or an air inlet channel; the combustion area can be partially or completely closed, even premixed combustion can be carried out, heat in high-temperature flue gas exhausted by the combustion area can be recycled by the air flowing in the air inlet channel, the premixed gas and / or fuel, the heat returns to the combustion area again to be utilized, and the heat efficiency of the heating system can be obviously improved; the temperature difference driving system is a Stirling system or a system composed of a temperature difference power generation sheet and a motor. The heating system with the temperature difference driving air inlet device does not need to be driven by external electric power, is high in heat efficiency, low in fuel consumption and free of exposed open fire, not only the heating temperature can be improved, but also can the temperature difference and oil smoke of a heated area and the like be reduced, and obvious advantages are achieved.

Description

Technical field [0001] The present invention relates to the technical field of heating apparatus, and more particularly to a heating system with a temperature difference driven air blowing device. Background technique [0002] A large amount of heat generated by the fuel combustion of the well-known commercial steam is directly discharged into the air, the thermal efficiency and the fuel utilization rate are low, and the waste is serious. Moreover, it is also necessary to equip power driven air systems; not only the volume, weight and production cost is large, but there is no power in the power-on, field or disaster relief, etc. Moreover, such a well-known heating system is generally open to open fire, not only the flame or high temperature flue gas directly roast the body and surrounding facilities of the operator, but the exhaust gas exhaust gas threatens, so that the operating space is too hot, but also exposed The open flame is easy to ignite the oil of the hood, the wild gra...

AI Technical Summary

Problems solved by technology

[0002] A large amount of heat generated by the combustion of fuel in known commercial heating systems such as furnaces is directly discharged into the air, resulting in low thermal efficiency and fuel utilization, and serious waste

Moreover, it must be equipped with an electric-driven air intake system; not only the size, weight and production cost are large, but it is also difficult to apply in occasions without power such as power outages, field or disaster relief.

Moreover, such known heating systems are generally exposed to open flames during work. Not only the flame or high-temperature smoke directly burns the operator's body and surrounding facilities, the exhaust gas tail gas threatens the health of the personnel, and the operating space is too hot. Open flames can easily ignite combustibles such as oil accumulated on the range hood, grass and trees in the wild, or tents

[0003] Chinese patent authorization announcement number CN204254692U discloses an auxiliary air intake device for a gas stove with a thermoelectric power generation piece, but the low-temperature end face of the thermoelectric power generation piece is far away from the air inlet and an additional cooling device is required, which is expensive and has a large volume and weight

Chinese patent authorization announcement number CN208886839U discloses a camping stove with a thermoelectric generator, but the cooling surface of the thermoelectric generator is isolated from the air inlet, the temperature difference cannot be maximized, and its power generation function cannot be maximized; As the temperature in the camping stove gets higher and higher, the temperature difference becomes smaller and smaller, and the power generation function will become worse and worse.

[0004] However, no matter whether there is an external power source or not, as long as the fuel is burned, there will be a temperature difference
