PROPANE-BUTANE SUPPLY FOR COKE OVEN AND BLAST FURNACE GAS ENRICHMENT IN REHEATING FURNACES

This article proposes organizational and technical measures to reduce energy consumption of re-heating furnacessection of hot rolling mill 1700 in hot rolling shop No.1 of “ArcelorMittal Temirtau” JSC, such as fuel combustionquality management, performed and presented calculation of energy consumption per unit of production. The industrial experiment was performed there. As it is known, one of the features of re-heating furnaces is the fact that the minimum specific fuel consumption takes place when burning it with the maximum possible pyrometric effect. To solve the research tasks, a fundamentally new 3D model of combustion products motion with the possibility of parameters correction to calculate and optimize the energy-efficient operation of the furnace was applied. Experimental data were obtained on high-precision stationary and portable equipment, metering devices passed state inspection, which excludes the unreliability of the data obtained.
