Jul 12, 2019 · The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a
Verify that the boilers and primary/feed water pumps stage up and down per the sequence of operations under all operating modes. Verify that the time delay between boiler start/stop commands are per design. To remove residual heat from the boiler, the primary/feed water pump operation time delay, after the boiler is commanded OFF, is per design.

and critical for normal boiler service life and correct operation. This is water free of excessive minerals and gases with a nominal pH of 7.8 ± 0.5. A pH reading of around 10.0 or higher can result in priming and surging, which can cause wet steam and/or flooding of the steam supply and steam header. A pH level only a single digit away from
Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of
