Galvanized flame tube SL 77-350, used for burner extension, allows adaptation of equipment to boilers with deep furnaces. Galvanized steel provides resistance to high temperatures and corrosion. The part is designed for SL series burners, but may be compatible with other models if mounting dimensions match. Burner extension is often required during repair or modernization of boiler equipment to optimize combustion. Before installation, ensure the tube length and diameter are exactly correct.
