Structure flow-disturbing mouth rotates at a high speed cooling air；Hot-air deflector prevents that flame is excessive, while stirs the High Temperature Gas of injection at a high speed
The incorporation time of stream increase hot-air and cold air.
The described side end face of secondary air channel one is connected with secondary air channel flow control valve.Regulation enters the acceleration of combustion gas tail gas
Excess air total amount in device.
Described high pressure positive blower lateral wall is connected with air inlet muffler.Reduce noise caused by high pressure positive blower.
What the utility model was brought has the beneficial effect that：System utilizes what is conducted heat by cross-ventilation heat transfer and spectral radiance
Physical characteristic and develop, whole chemical energy of natural gas can be converted to the heat energy of hot blast.In temperature environment below 600 DEG C
Burnt, so as to limit the oxidizing process of nitrogen in air.There is the system and be efficiently provided simultaneously with nitrogen oxides
The environmental protection index of zero-emission.At the same time it is few using material because the system architecture is compact, the characteristic such as motion stabilization.Drop significantly
The low equipment cost using user, space cost and fuel consumption cost.
