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...

Air-cooled condenser in power plants takes a risk of freezing in extremely cold days, so it is of benefit to the safe and economical operation of direct dry cooling system to propose the anti-freezing principles and take measures. On the basis of the heat load balance between the exhaust steam...

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...

Nickel supported on SBA-15 doped with CeO₂ catalysts (Ni-CeO₂/SBA-15) was prepared, and used for steam reforming of toluene which was selected as a model compound of biomass gasification tar. A fixed-bed lab-scale set was designed and employed to evaluate the catalytic performances of the...</sub>
