Design of Shell and Tube Heat Exchanger using flue gas from calciner Prasanth.B.Chandran 1Student, Department of Mechanical Engineering, Anna University of Technology, Tirunelveli, India E-mail: Abstract Heat from flue gas in the calciner unit can be utilized to heat another fluid by using a shell and tube heat exchanger. Calciner is a device used for calcinations process and a lot of flue gas is released from the calciner, with respect to its capacity. Thus a lot of heat energy is being wasted along with the flue gas into the atmosphere. This waste heat from the flue gas can be effectively used to heat some other fluid. This waste heat is here utilized to heat water which can be used for some other purposes. For this a heat exchanger is essential. Here a shell and tube Heat Exchanger is designed taking into account various other parameters. Keywords; Heat exchanger, Shell, Tube, Heat transfer, Temperature, Enthalpy, mass flow rate 1.0 HEAT EXCHANGER A Heat Exchanger is a Device which is used to transfer heat from one fluid to another fluid. One of the fluid is considered as the hot fluid and the other fluid is the cold fluid. The hot fluid will transfer its heat to the cold fluid in the Heat exchanger. 1.1 TYPES OF HEAT EXCHANGERS * Air Cooled * Double Pipe * Spiral Plate and Tube * Shell and Tube 1.2 HEAT EXCHANGER TYPES Heat exchangers are ubiquitous to energy conversion and utilization. They involve heat exchange between two fluids separated by a solid and encompass a wide range of flow configurations. Parallel Flow Counter flow Figure No 1.1 * Simplest configuration. * Superior performance associated with counter flow. 1.3 SHELL AND TUBE HEAT EXCHANGER A Shell and Tube Heat Exchanger is one in which hot fluid flows through the Shell and the cold fluid flows through
