Abstract

Studies were made of the changes in heat loss that occur during the operation of a blast furnace with pulverized-coal fuel (PCF). It is shown that the use of PCF increases heat losses relative to the furnace's heating capacity. These losses increase from 1.15% without PCF use and an intact lining to 3.7% with maximal lining wear and the use of PCF at a rate of 187 kg/ton pig iron. Minus the chemical heat of the top gas, the heat losses incurred relative to the heating power of the furnace increase from 2.78 to 8.81%.

Information from the technical proposal (Document No. P002646-TP, edition 1, from 12.18.2012) that the company Danieli Corus BV sent to the Alchevsk Metallurgical Combine for replacement of the lining of blast furnace No. 1 (with the use of an integrated design for the shell, the lining, and the cooling system developed by Hoogovens®). The replacement was planned for 2013/2014.
