The Design of 120 Round Annular Furnace
Abstract: Annular furnace is a kind of rotary hearth furnace, it relies on the rotation of the bottom of the furnace, and it’s body is fixed, make the material stock placed on the bottom of annular furnace as the bottom out of feeding mouth to mouth, and in turn after preheating section, heating zone, soaking zone, complete all the heating process. The stove use the way of side feed and side discharge and heat with side burner. This design is mainly aimed at 13 meters in diameter size of annular furnace, fuel, pipeline system and smoke exhaust system design, including the calculation of fuel combustion and billet heating time, the determination of the basic size of the stove, the calculation of heat balance, the determination of fuel consumption, the calculation of pipeline system and smoke exhaust system. The furnace is pided into three, respectively preheating section, heating and soaking. This design adopts the producer gas as the main fuel of annular furnace. In the design of the exhaust system, the main task is the calculation of chimney flue resistance. In the design of the pipe system, the main task is the size determination of gas pipe and air pipe and calculation of the resistance.
Keywords: annular furnace; heat balance; pipeline system; smoke exhaust system
