The Design of the pre-heater of coke-oven gas
Abstract：This design manual is about the design of floating heat exchanger. Heat exchanger is a kind of heat transfer between the material and energy saving equipment, which is a kind of widely used process equipment in the petroleum chemical industry, metallurgy, electric power, light industry, food industry .The heat exchanger which this topic research is for a given design parameters, according to the requirements of the relevant provisions, determined by the overall scheme, the determination of physical parameters, thermodynamic calculation, resistance calculation, detail structure (takeover, baffle plate, flange and pipe boxes, etc.) design heat exchanger products design, intensity, etc. Design of the first part is about the physical parameters and thermodynamic calculation, in the second part is based on a given task to design the overall structure of the heat exchanger and the internal structure, such as the choice of materials, the calculation of pipe plate box, the calculation of the flange, etc.
Key Words: Floating head heat exchanger; Flange; Tube plate
