Thermal evaluation and efficiency improvement analysis of top-combustion regenerative heating furnace
In order to improve the thermal efficiency of the heating furnace and reduce gas consumption,the study and analysis were conducted on the thermal efficiency of a regenerative heating furnace of a semi-coke enterprise in Shenmu City based on its industrial operation data.The process flow,characteristics,equipment and main parameters of the regenerative heating furnace were introduced.Based on the industrial operation data tested according to GB/T 32287-2015"Method of Determination and Calculation of Heat Balance for Hot Stove in Blast Furnace",the thermal efficiency of the heating furnace before and after the improvement was calculated.The analysis results indicated that by reducing the exhaust gas temperature by 10℃and insulating the hot gas pipeline,the thermal efficiency of the heating furnace system could be increased from 82.3%to 86.3%.
