The aim of this research is to investigate the effect of ambient air temperature on the steam generation. A parametric study was performed based on exergy analysis to study the impact of ambient air

However, the very nature of their operation subjects steam turbines to extreme conditions, such as high temperatures, pressures, and the potential for corrosive environments.

Steam-temperature control functions have not changed much over the years; however, as the HRSG fleet ages some of these problems are starting to reveal

Uncontrolled acceleration is very dangerous and precautions must be taken to ensure rapid closure of the steam valves in the event of a disconnection of the electrical generation.

It will be apparent that it is the pressure which drives the turbines, but if the pressure is too high compared with the inlet steam temperature, the temperature drop through the turbine will be excessive.

High temperatures can increase efficiency but may also cause thermal stress on turbine parts. Sudden or extreme changes in temperature can lead to expansion or contraction of

fuel was assumed to be at the ambient temperature of 25 o C and 1 atm. As shown in Fig. 2, the second law efficiency is insensitive to ambient air temperature, for instance at excess air of 25%, the second
