The Bell & Gossett WU model is aided by a B&G booster which pumps boiler water through the shell of the transfer unit for efficient, high capacity heating solutions. Bell and Gossett also offers a complete line of tank heaters, straight tube heat exchangers, tank suction heaters, gas coolers, and compact heat exchangers.
In the case of a steam system, a portion of the process steam is tapped off and used as a heat source to reheat the feedwater in preheater stages. Figure 8 is an example of the construction and internals of a U-tube feedwater heat exchanger found in a large power generation facility in a preheater stage.
U-tube Heat Exchanger - EllisBy utilizing a shell and tube heat exchanger from Ludell, your facility will increase efficiency and decrease spending. The Ludell Wastewater Heat Recovery System recovers heat from the outgoing wastewater by transferring it to the incoming fresh water. The design is simple. Countercurrent water flows (wastewater and freshwater) exchange energy through a series of tubes up to a five-degree approach in temperature (wastewater in and fresh water
A Feedwater Heater is a power plant equipment used to preheat water delivered to a steam generating boiler, by recovering the heat from the turbine extraction steam. Preheating the feedwater reduces the irreversibility involved in steam generation and improves the thermodynamic efficiency of the system.
