Shell and Tube Heat Exchanger
Flue Gas Heat Recovery Study Every 20C heat recovered from Flue Gases translates to ~1% improvement in Boiler efficiency. For flue gases with SOx and/or sooty, particulate material Conventional heat exchangers suffer from cold spot and SOx condensation corrosion due to cold spots. Also, sooty flue gases offer challenges with respect to cleaning and maintenance in conventional exchangers. HPHE operates at isothermal conditions and hence does not suffer from cold spot formation. Flue gases can be cooled close to the condensation temperature allowing higher heat recovery. Automated or manual in-situ cleaning of HPHE makes it an ideal exchanger for sooty flue gases. This study focuses on a boiler producing 6 t/h saturated steam at 10 bars. Two fuel cases have been considered for this study, Briquettes and Natural Gas. Briquette fired boiler The flue gases will contain a high amount of particulate/soot. The evaporator section of the HPHE for this case has non finned smooth heat pipes and is fitted with an Ultra-Sonic soot blower. The graph on the right shows the Cost Saved per year and HPHE CAPEX for 60, 80, 100, 120 �°C heat recovered from flue gases, assuming the flue gas exits the boiler at 200�°C. Savings is calculated based cost of steam @ Rs 2.3/kg Savings is calculated based cost of steam @ Rs 4.2/kg Natural Gas fired boiler The HPHE for this case will have fins in the evaporator section to improve the overall heat transfer. In case there is SOx in the flue gas, the gases can be cooled to a temperature close to the dew point at the stack exit. The graph on the left shows the Cost Saved per year and HPHE CAPEX for 60, 80, 100, 120 �°C heat recovered from flue gases, assuming the flue gas exits the boiler at 200�°C. The shown Savings and CAPEX figures are estimated values. Connect with us to find our the exact cost savings and HPHE CAPEX for your project.
Tubular heat exchanger is a straight tube heat exchanger with one or more inner tubes situated in a shell. It is designed to accomplish the efficient heat transfer from one medium to another. The user can choose different materials according to their needs, such as carbon steel, stainless steel, copper pipe, aluminium tube, steel aluminum complex pipe and so on. We could manufacture standard and customized equipment to meet your needs.
Tubular exchanger is the most widely used heat exchanger on chemical and alcohol production. It is mainly composed of shell, tube plate, heat exchange tube, head, baffle and so on. Required material, can be made of ordinary carbon steel, copper, or stainless steel. During heat exchange, a fluid enters through the connecting pipe of the head, flows in the pipe, and flows out through the outlet pipe at the other end of the head. Another fluid enters by the nozzle of the shell and flows out from another nozzle on the shell. This is called the shell process. The structure of the tube heat exchanger is simple, compact and cheap, but the outside of the tube can not be cleaned mechanically. The heat exchanger tube bundle is connected to the tube plate, which is welded to both ends of the shell respectively, and is connected to the top cover. The top cover and the shell are provided with a fluid inlet and outlet pipe. A series of baffles perpendicular to the tube bundle are usually arranged outside the tube. At the same time, the connection between tube and tubesheet and shell is rigid, while outside the tube are two kinds of fluid with different temperature. Therefore, when the temperature difference between the tube wall and the shell wall is large, due to the thermal expansion of the two are different, a large thermal stress is generated, so that the tube twists or loosens the tube from the tube plate, or even destroys the heat exchanger.

Gireesh shell and tube heat exchanger is the most common type of heat exchanger designs. As its name implies, this type of heat exchanger consists of a shell with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed by several types of tubes: plain, longitudinally finned, etc.
