Oil-Gas Burner GMR-150

This specification applies to gas-oil burners with adjustable flare GMR (hereinafter - the burners) that are designed for use in high-temperature industrial furnaces for various purposes in the modes of "long" and "short" flare and low-temperature furnaces only in the " short" flare mode, where gas, fuel oil or other liquid fuel are to be used in their separate or co-burning.

 

Flare parameters’ adjustment is achieved by the redistribution of the ventilation air between two air channels, direct channel and channel with swirler.
