The exhaust temperature of the heating furnace is very high. Is there any way to reduce it?

The flue gas temperature of heating furnace is very high, and the methods and measures to reduce the flue gas temperature;

1. The exhaust temperature of the heating furnace should be controlled within the design exhaust temperature range, which is generally greater than 160 degrees and above the dew point temperature.

2, strengthen the control and adjustment of furnace, delivery, air volume to be reasonable, and the oxygen content of flue gas is reasonable at 3%.

3. Even if your negative pressure and oxygen content are adjusted normally. If the load of heat recovery part (convection section or preheater) is too small, that is, the area of exhaust pipe is too small, the exhaust temperature will be very high.
