Design of Slab Walker Continuous Heating Furnace for 200t / h Combustion Gas

Abstract: In the subject design, I consult a large number of related books and documents online about stepping furnace and thermal furnaces, I also review the "industrial boiler" and "furnace thermal" books which has learned。 Through the curriculum design, I have deepened the basic knowledge of heating furnace and heat engineering, I also mastered the basic method of heating furnace design and the basic structure of the heating furnace。 The design of the first comprehensive analysis of the basic information about the reheating furnace, and points out its differences with the reheating furnace。 The second step is the calculation of the combustion of mixed gas fuel。 The third step is the thermal calculation of furnace heat transfer, The calculation part is firstly discuss the calculation of fuel furnace heat transfer and metal heating problems, and then calculate the main dimensions of the furnace according to different heating time。 The back is the calculation of the thermal balance of the stove, and then according to the results of calculation, select the burner and heat exchanger to meet the needs of the work。 Finally, calculate the resistance of the piping system, the selection of the blower and the fan。 To complete the entire design of slab continuous beam reheating furnace with a yield of 200t/h (mixed gas) process。 

Keywords: Walking beam reheating furnace； Furnace heat exchange; Metal heating ；Air heat exchanger ；Flue
