- the first part of the fuel oil is loaded together with its carriers, and the second is the flow of the acid from the moment of the onset of the melting of the liquid, which results in the liquid being consumed.
- the task posed has been resolved because, in the process of production, the goods have become in the acid invert from the equipment
- Natural gas coal is dependent on the content of volatile constituents in it. For the sale of volatile constituents, in the amount of $ 25 wt., The required coal gas is taken in the amount of $ 30% of the total consumption of gas
- the fuel supply in the burner starts supplying the burner.
- the degree of assimilation of acid in the course of heating and pressure is different. ⁇ first stage, when
- 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.
- the fuel is charged to the consumer for a second time
