The BOILER HOUSE
The Boiler House is a basic source power engineering operation which is focused on generation of superheated steam used for combined production of electricity and heat and other utilities for the needs of metallurgical processes at U. S. Steel Košice. The Boiler House has 7 steam boilers of which boilers K1, K2 and K3 use metallurgical gases (basic oxygen furnace gas, coke oven gas, and blast-furnace gas) as a main fuel and natural gas as an additional fuel. Boilers K4-K7 are coal boilers where coal is transported by conveyor belts from the coal yard located at the Cokery DP to coal boiler tanks.
The machine room
The Machine Room ensures high-pressure steam conversion to electric power, medium pressure technological steam, blast, compressed air, heat for heating, demineralized and softened water.
The Machine Room heating part main equipment ensures primary conversion of high-pressure superheated steam from the Boiler House (9.42 MPa/13.6 MPa 540°C) to medium pressure technological steam.
The Boiler House metallurgical part equipment ensures hot blast generation for the needs of blast furnaces and compressed air generation for the needs of the Oxygen Plant (oxygen production for Steel Shops) and for the company-wide compressed air distribution.
The Machine Room also includes the Chemical Water Treatment Plant producing demineralized and softened water.
