FIELD: manufacturing technology.
SUBSTANCE: invention relates to melting unit with side submersible combustion of pulverized coal and oxygen enriched air, which provides high efficiency and wide applicability at low operating costs. Proposed melting device comprises melting furnace, pipe for supply of pulverized coal, tube for supply of air enriched with oxygen and communicated with air source, and units for injection of pulverized coal located on two opposite side walls of smelting furnace at distance between them. Each unit for injection of pulverized coal is made in the form of a pair of tuyeres adjacent to each other for pulverized coal and oxygen tuyere. Each tuyere for pulverized coal is connected to a pipe for supply of pulverized coal, each oxygen tuyere is connected to a pipe for supply of oxygen enriched with oxygen, and each specified unit at least partially passes into smelting furnace.
EFFECT: melting apparatus with side submerged combustion of pulverized coal and oxygen enriched air is proposed.
