2018-12-5 · the operational standards for High-AVT (high pH) water treatment that Mitsubishi Hitachi Power Systems, Ltd. (MHPS) has applied at actual plants since 2001 were adopted. High-AVT water treatment has been increasingly applied as a measure against Flow Accelerated Corrosion and

Vogt is a "company of HRSG firsts." Tracing back over 135 years, Vogt is credited with producing the very first HRSG, the first three-pressure-level HRSG, the first re-heat HRSG and others. Today, operators of more than 600 HRSGs in over 40 countries consider Vogt their one-stop source for

2  · FAST START AND PEAK CAPACITY CONSIDERATIONS FOR COMBINED CYCLE POWER PLANTS BY JORDAN BARTOL As renewables such as wind and solar continue to ramp up in the U.S., the need for faster start-capable grid augmentation is on the rise. In the Heat Recovery Steam Generator (HRSG) realm, many new unit construction projects are touting fast-start capabilities. Early-to-mid

The need for both high efficiency and cycling puts conflicting requirements on Heat Recovery Steam Generation (HRSG) pressure parts. Application of new or higher-grade materials is an option.

What is an HRSG Academy? Our HRSG Academy is a 3-day course that summarizes the important "lessons learned" by HRST engineers, designers and technical advisors who have experience from hundreds of HRSG inspections and problem investigations each year.

The Diverter Damper system controls the flow of turbine exhaust gas (TEG) between a bypass stack or the HRSG. Forney's HRSG isolation damper allows exhaust to enter the HRSG while the bypass damper is closed, and upon closing the isolation damper and opening the bypass damper, forces the exhaust gases up the bypass stack.

The HRSG can rely on natural circulation or utilize forced circulation using pumps. As the hot exhaust gases flow past the heat exchanger tubes in which hot water circulates, heat is absorbed causing the creation of steam in the tubes.

2018-1-2 · gas path, water vapor in the superheater and reheater sections of the HRSG will condense. When the gas turbine is fired it heats the superheater and reheater tubes. Any undrained water will be pushed by steam into the hot tubes and causing thermal-fatigue damage and eventual tube failure.

Operational results 5.1 pH value Hydrazine and ammonia are used in the conventional AVT(R) feedwater treatment, but High-AVT (O) only uses ammonia. The ammonia concentration will increase to change the pH

The GT is coupled with the electrical generator to produce electrical power.
