What is the reason why the chimney of horseshoe flame glass kiln with gas stove as fuel emits yellow smoke?

Reason: Because the kiln changes direction every 20-30 minutes, the gas in the gas regenerator and flue needs to be replaced by flue gas. Under normal circumstances, the gas is replaced by flue gas, enters the gas exchanger, and finally enters the chimney for discharge. Because the gas contains tar and other gases, yellow smoke or even black smoke will appear in the flue gas.

Solution: Reversing gas recovery device of regenerative horseshoe flame kiln (patent number 20 1320776388.5).

Design principle: The gas recovered by the device does not burn outside the flue and furnace, but re-enters the furnace for combustion through the recovery device. This can not only make full use of energy, reduce waste, but also truly achieve no gas emission. Completely changed the history of chimney emitting yellow smoke or even black smoke when reversing, and achieved the purpose of energy saving and environmental protection. At the same time, the system can be directly incorporated into the kiln automatic control system, and the operation is simple and reliable. It's really economical, environmentally friendly and affordable!
