Desuperheaters—often called attemperators—in heat-recovery steam generators (HRSGs) are located between the primary and secondary superheaters and reheaters, and sometimes after the final stage of ...

At large institutional facilities and educational campuses, particularly those located in colder climates, steam flow measurement is a critical challenge. Facility operators want to accurately track ...

Steam distribution from the boiler to the points of end use should occur with minimal loss of energy. However, the total amount of steam distributed (figure 1) never matches the amount of steam coming ...

Vortex flowmeters have been available on the market since the late 1960s, and the number of applications they are used for has steadily increased. Over that same time, reliability has also increased, ...

(Editor’s Note: This story originally ran in November 2008 and has proved a perennial favorite of Power Engineering readers. With the New Year we thought we’d share it again. Click here to see the ...

How low can you go? That’s the question owners of gas turbine combined cycle plants are asking these days as they are being called upon to operate those units for rapid response in markets where load ...

Combined-cycle power plants operate by integrating a combustion turbine generator (CTG) and heat recovery steam generator (HRSG) with a steam turbine generator (STG). However, during some modes of ...

ABB's FPD470 Wedgemeter series measures gas, liquids, and steam. They contain a solid V-shaped flow restriction which makes them highly robust. The FPD470 wedge meters are bi-directional and mainly ...

The electricity used in various chemical plants is obtained from a co-generation plant burning waste gas streams or from a natural gas power plant. In large boilers, such as the one shown in Figure 1, ...
