The box-shaped furnace with vertical coils, for free vertical flare combustion of com-bined fuel. Radiation coil pipes are arranged on all four walls of radiation chamber. single-row screens of double-end illumination are arranged on the radiation chamber walls. There are seven standard sizes of these furnaces, each standard size differs from another in amount of radiation chambers. Above the radiation chamber the con-vection chamber with horizontal plain pipes is arranged. Burners can be maintained from both sides. The furnaces are lined with light-weight refractory concrete. Furnaces VS are installed in the LK-6-U system. They can be applied in AT units and also at sec-ondary treatment systems, etc.
