  • the consumption of oxygen for burning gas coal is low.
  • the oxygen content in this process depends on the main form of the quantity of combustible gas phase which is emitted from coal, which is free from gas emissions. Therefore, at this stage of heating, the acid should be maintained at a level that ensures the burning of combustible gas phase.
  • the total oxygen consumption for the melting plant is 103 m 3 .
  • the yield of liquid steel is 1003 kg, that is, $ 91.2 per annum. Duration of floats for production
  • the total acid flow to the melting site is 106 m 3 .
  • the end of the year is 91, 1. Gas supply - 57 m 3 .
  • the consumption of acid is equal to 4.55 m 3 / min, which is 0.26 m 3 / min for I kg of coal gas.
