Improving HEAT EXCHANGER PERFORMANCE Via Wireless Technology

Because heating the transfer liquid costs money, less heat is better. Exhaust steam is fed to air-cooled heat exchangers to act as condensers, but then liquid condensate flows to shell-and-tube heat exchangers heated by steam and acting as feedwater heaters. Because electric power demands fluctuate, the amount of steam generated also fluctuates. Applying Instrumentation Getting the most efficiency out of a common shell-and-tube or plate heat exchanger requires knowing much detail about what is happening inside. Because the main operating parameters relate to flow rate and temperature differential for the two respective fluids, it is important for them to be monitored. [...]in the real world, 100 percent efficiency is not practical, so a company must determine how much deviation it is willing to tolerate before it takes the heat exchanger out of service for cleaning.
