Abstract

Disclosed is an axial-flow type thermoelectric device. A turbo type burner, a heat exchanger and a motor are adopted, a power generator is driven to be started by means of rotation of a turbine of the burner, and hot air of the burner pushes an axial power turbine in the power double-layer heat exchanger to drive the power generator. Water jackets are arranged outside the burner, a flame chute and a volute casing and on the heat exchanger and connected with a radiator to provide a heating source. Auxiliary power is provided for the power turbine besides the action of the hot air of the turbo type burner, and the utilization rate of energy is increased. The axial-flow type thermoelectric device can be used in small or confined space to serve as a heating and power generation device in a tank or armored car and the like and can also serve as a power generation and heating device independently for outdoor camping and on an island or frontier sentry and the like. The axial-flow type thermoelectric device is simple in structure and low in production cost and has promotional value.

Description

technical field [0001] The invention relates to an auxiliary energy device for providing power and heat sources, in particular a device which uses a turbine burner as a micro-combustion engine and has the functions of power generation and heat supply. Background technique [0002] At present, the burner is composed of an electric fan, a combustion chamber, an igniter, etc. Other oil and gas burners at home and abroad basically consume electricity, but they do not generate electricity themselves. The working electricity must be provided by an external power supply. Among them, the burner fan requires power consumption ranging from several kilowatts to tens of kilowatts, including fans, swirl plates, combustion chambers, igniters, etc. Although the turbocharger body of the vehicle is just a burner, its startup mainly adopts a special starter motor. Because of its high cost and no other functions, it has not been widely used in other fields. [0003] In addition, the turbochar...
