Gas-oil burners with regulated flame ГМР

These burners are intended for use in the heating systems of high-temperature industrial furnaces for various applications in the modes of «long» and «short» flames and for low-temperature furnaces only in the mode of «short» flame in which it is possible to use gas, oil or any other liquid fuel with their separate or combined combustion. The regulation of the flame parameters is achieved due to redistribution of the fan air between two air ducts, direct duct and duct with a swirler. The burners are not fit for repair. Burners ГМР are manufactured in the climatic version of mounting 3 according to GOST 15150-69. Burners ГМР are manufactured in seven standard sizes according to the thermal power and depending on the body construction: 1 — with normal burner body for all rated consumptions of gas; 2 — with elongated burner body (only for rated consumptions of gas 50, 100, 150 nm³/h).
