52.1.1 Shell and Tube Heat Exchangers Shell and tube heat exchangers normally consist of a bundle of tubes fastened into holes, drilled in metal plates called tubesheets. The tubes may be rolled into grooves in the tubesheet, welded to the tubesheet, or both to ensure against leakage. When possible, U-tubes are used, requiring only one
Shell & Tube Heat Exchangers usually provide long service life with little or no maintenance because they have no moving parts. However, there are several types of mechanical failures that can occur, but with a little maintenance and understanding, they can be prevented. Condenser Heat Exchanger - TeeraindustrySpecifications. Tube heat exchanger. - High efficiency heat exchanger. - Based on customer's requirement. - Shell & Tube Heat Exchangers. Tube heat exchanger. Introduce. High heat exchange speed, high temperature resistance (400°C) and high pressure resistance (2.5MPa); High efficiency and energy conservation:The heat transfer coefficient reaches. 3000-4000W/m2.°C in the transfer from steam to water and 2000-3500 W/m2.°C in the transfer from water to water.
The steam to fluid heat exchanger utilizes steam which enters the shell through a top vapor opening and surrounds the tubes inside of the shell. As the latent heat of steam is transferred to the medium inside of the tubes condensation occurs. Shell and tube heat exchanger:condenser, preheater, gas Feedwater heater (LP/HP) These tube and shell type exchangers are intended to heat the feed water for the boiler of a thermal electricity production unit. It is the steam or hot condensates that heat the water.
Jun 08, 2021 · A steam condenser is a closed vessel-type heat exchanger applied to convert low-pressure exhaust steam from the turbine to water. A steam condenser is a mechanical device employed to condense exhaust steam of the turbine into the water. It conducts this process with the help of cooling water that circulates inside it from the cooling tower.

Steam to Water Heat Exchangers The operation of the shell and tube heat exchanger is as follows. Steam enters the heat exchanger shell through the top vapor opening and surrounds the outside of the tubes. As energy is transferred through the tubes it heats the water inside the tubes. The heat transfer condenses steam inside the shell forming condensate that drops to the bottom of the heat exchanger shell.
