Additional independent air channel, which can adjust of the flame outlet temperature as required. Flame temperature: 50～1500℃.

The secondary air with large flow is supplied independently, which ensures the complete combustion of fuel even in the condition of low flame outlet temperature and large excess air coefficient.

High outlet velocity is possible even with low energy supply, the convection heat exchange of furnace is strengthened by the secondary air.

Fuel: natural gas, LPG, town gas and other fuel gases.
