Water gage glasses continue to be a vital instrument on power boilers that are constructed to comply with the requirements of the American Society of Mechanical Engineers’ (ASME’s) Boiler and Pressure ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...

A century-plus of steam-generated power production has shown the importance of water and steam chemistry. Just one boiler tube failure in a conventional unit or heat recovery steam generator (HRSG) ...

It takes a large number of control valves to run a power plant, and while some valves are more critical to plant operations than others, it always follows that when a severe service valve fails, the ...
