Basic patterns of formation and burning of associated gases (hydrocarbons and other units) due to thermal decomposition of admixtures in scrap-iron while pre-heating with exhausting gases of gas-turbine unit are considered. One of the most effective variants is offered of solving the major ecological problem in metallurgy – that of the formation of dioxins and furans, represented in high temperature afterburning of impure stream of gases alongside with highly effective energy production in steam utilizing boiler. The functional dependence is given of the time and the temperature of burning and the digital field is built of the demanding supply of natural gas for the afterburning of the stream of gases.
