2015-5-1 While the positive effect of raising turbine inlet temperature to increase overall plant efficiency is often quoted and discussed, another figure is mentioned to a much lesser extent: The HTF outlet temperature at the steam generator exit, which also has a profound influence on cycle efficiency due to the fact that allowing higher temperatures allows moving to much higher evaporator pressures
Coal mill hot air inlet temperatures should never be more than 600 ° F and the outlet temperature should not exceed 200°F on Raymond coal mills. If the flow of raw coal to the coal mill is interrupted for any reason (for example plugging failure of the coal feeder etc.) the outlet temperature of the coal
The arranging location (N side-rei) and required heat duty (6 side-re, i) of the side-reboiler are identified through exergy grand composite curve (EGCC) and avoidable exergy destruction curve (AEDC), as proposed by our group (Wei, Bandyopadhyay, 2007, 2011, 2002, 2003, 2012).Thus, the inlet and outlet temperatures of the side-reboiled stream are identified, and the available heat duty of the

2020-11-10 A higher temperature at the outlet of the steam turbine implies a pressure increase for both natural gas combined-cycle and coal-fired power plants. This increase is between 43 and 48% per 10 °C of ambient temperature increase, when using once-through cooling systems and between 55 and 60%, when using recirculating cooling systems.

2020-9-24 The ability to handle high temperatures is one of the main reasons why gas turbines are more efficient than steam turbines such as used in coal plants. For instance, the turbine inlet temperature of a gas fired Mitsubishi 501J is about 2,900 0 F while in a supercritical coal plant it is about 1,300 0 F. Temperature however is not the whole story.
