METHOD OF HEATING OF MINING UNITS Russian patent published in 2017 - IPC F23C1/04 

FIELD: metallurgical engineering.

SUBSTANCE: method of heating the mining units includes the supply of gaseous fuel and air to the heated blown layer of lump materials, their mixing in the fractional void with the formation of the initial cold air-gas mixture and its ignition in the fractional void, while in the heated blown layer of lump materials is supplied by separate jets with twist parameters from 0.1 to 5.0 mixture of gas and air at a ratio of the amount of oxygen to the amount of combustible gases from 0.1 to 7.0, and ignition of the gas-air mixture is carried out by its heating to a temperature of 800-1050°C.

EFFECT: increasing the uniformity of the temperature field of charging materials along the unit section and obtaining a product with a stable chemical composition.
