Steam Inlet Temperature - an overview | ScienceDirect Topics

The inlet steam temperature from the parabolic type of CSP is relatively low below 400°C compared with the typical steam temperature of 600°C for conventional fossil-fuel power plants. This temperature limitation for parabolic trough type CSP is due to the degradation limit of the synthetic oil that is often used as the conventional HTF.

Boiler Combustion | CleanBoiler.org

Selective non-catalytic reduction involves the injection of a NOx reducing agent such as ammonia or urea into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.

Boiler Introduction | CleanBoiler.org

Superheat refers to the process of increasing the temperature of steam above about 400°F and 100 psi to produce a very dry steam with absolutely no water vapor. This feature is most common in very large power plant boilers of watertube construction. An additional heat exchanger capable of the high temperatures and pressures is required.
