High temperature cumulative combustion air-heating furnace.It uses the cumulative heat exchanging principle and recovers the combustion-supporting air(gas) when the air reached its combustion limits.Then preheat the gas to a high temperature,thus reducing the fuel consumption.Our company have successfully resolved the problem that hot dirty gas can not commutate,and we put the hot dirty gas in the use of commutation Combustion.

    On the basis of traditional heating furnace,our company resolved the problem of vaporization cooling self-cycling.On the heating furnace where unburnt earth are more than 6 m,we started vaporization cooling system without causing fire,energy-saving and environmental protection finally realized.
