E-6035 Fuel Gas Performance Heater
General information
Heat exchangers (heat exchangers) heat gas for a subsequent system requirement or to counteract the Joule-Thomson effect. This is caused, for example, by pressure reduction in a gas pressure control system. Heat exchangers can also be designed to function in reverse as coolers. They are designed as welded steel constructions in vertical or horizontal design.
Function
VEV-LS fuel gas performance heaters are used in high-efficiency combined cycle gas and steam power plants (CCPP). The gas is heated to 185 °C-220 °C (365 F-428 F) in order to achieve the best efficiency of the gas turbine and the overall plant. Preheating the gas to these high temperatures enables the use of smaller quantities of gas to operate the turbine.
Pressurized, condensed superheated steam from heat recovery systems is used to feed water into the performance heater.
In the standard version for gaseous media, performance heaters function as counterflow tube bundle heat exchangers and are arranged in series next to or on top of each other. The gas flowing through the tube side is heated by the hot water or superheated steam flowing around the shell side. The flow around the tubes on the shell side is optimized by baffle plates.
The application of the heat exchanger and the heating medium determine whether the shell side is designed to be pre-pressurized. The tube bundle can be permanently welded or removable.
For each application, it is checked whether the thermal linear expansion requires the use of expansion joints.
