A two-stage ORC (organic Rankine cycle) is proposed, by which low-grade heat of exhaust flue gas of a 123.5 MW gas-steam combined cycle power generating unit, as well as the cryogenic energy of LNG (liquefied natural gas) can be effectively recovered and utilized. R227ea and R116 are selected...

The direct air-cooled power generating units subjected to the environmental natural wind were influenced by the cluster effect of the axial flow fan cluster and the exhaust hot air recirculation simultaneously. The coupling effects would lead to complex variations of fan cooling capacity in...
