Modern technologies of melting with waste products as renewable fuel and energy resources

Nowadays energy-saving technologies are widespread. They allow to optimize thermal balance of the converter melting, decrease consumption of the liquid cast iron and increase the share of the processed scrap up to 35-40% accordingly. To the latest ones can be referred different methods of metal blow with afterburning of the effluent gas in the working space of the installation, scrap preheating with help of fuel-oxygen tuyere, additional tuyeres of the burners and wide use for heat carriers heating, first of all carbon-containing materials in lump or powder shape. But at the same time with the exception for cast-iron saving there is probable decrease of some technical and economic showings of the process, for example, metal quality, lining life and liquid yield of steel. Advanced solution of this problem is use of renewable types of energy resources including domestic garbage.Nowadays energy-saving technologies are widespread.
