Tubular-furnaceheating equipment is a kind of firepower, which the use of fuel combustion inthe furnace when the flame and flue gas temperature as a heat source, heatingin the furnace tube in the high-speed flow of medium to reach the processtemperature requirements, in order to supply medium during fractionation,decomposition or reaction process, such as the heat required to ensure normalproduction.
Thedesign for the annual production capacity of two million tons of crude oilcylinder tube furnace, in the completion of the design of the main paragraph ofradiation, convection, as well as the size of the stack process, the heatbalance, steel structure and the calculation and checking Selection of thevarious furnace components. Room size radiation technology, including radiationchamber furnace tube diameter, tube wall thickness, tube length, the root ofthe number of tube radiation, such as room dimensions; convection process roomsize, including the form of convection furnace tubes, furnace tube diameter,wall thickness of the tube, the tube row number and the root of the number ofeach row, the heat balance calculation of the part, including fuel, thespecifications of the burner and root number.
The gistof the present furnace design with high thermal efficiency and fuelutilization. Measures often used to reduce the furnace flue gas temperature,reducing the over-heated air coefficient, the Department of incompletecombustion to reduce the loss of chemicals to reduce the mechanical loss ofincomplete combustion, reduce heat, such as furnace wall. Flue gas can also beset up waste heat recovery system to increase the thermal efficiency offurnace.
