The finned tubes are the core technology of Air-cooled heat exchangers. SPG Dry Cooling has a wide range of finned tubes available:round tubes with L-fins, extruded fins, multi channel tubes (MCT), round aluminum fin tube (RAFT) and many others. You
Apr 01, 2016 · The lean amine air-cooled heat exchanger (HEX), E-2109, is a fin fan cooler consisting of 5 bays with 2 fans per bay. The louvers on each bay can be opened or closed manually. The fan blade pitch will be set manually on one fan and the pitch on the other will be controlled by controller sensing the exit amine temperature.
Common Operating Problems with Air Cooled Heat ExchangersReverse flow is a common problem in older air-coolers. This misdirected flow causes two problems for the heat exchanger:1) the obvious one is a net loss in the amount of air that travels through the tube bundle to provide cooling; 2) the secondary effect is that when the air flow returns to the suction side of the fan, it is again sucked up and creates artificially high inlet air temperatures
with being the overall heat transfer coefficient, the heat transfer area, and is the log-mean temperature difference. Equation (13)(13) is used when simple counter or co-current flows exist. If the flow pattern is more complex (such as the case with most shell and tube heat exchangers), then a correction factor ( ) term is used and the
