Furthermore, the solution of increasing the spacing between burners has not completely solved the air circulation problem and has increased the footprint.
An automatic blower is installed outside the combustion chamber to deliver air into the combustion chamber through a blower and ventilation pipes. The working intensity of the blower is adjusted in conjunction with a gas flow monitoring device to ensure sufficient oxygen supply in the combustion chamber. Multiple air outlet channel structures are adopted to deliver air evenly.
It achieves complete combustion of flare gas, avoiding problems such as black smoke and flash explosion caused by incomplete combustion, while reducing the spacing between burners and reducing the footprint.
