heat recovery steam generator

When U.S. President Jimmy Carter signed into law the Public Utility Regulatory Policies Act of 1978 (PURPA), he unintentionally ignited the worldwide deregulation of electricity markets, which in turn began a worldwide technology race between two distinct types of power plants: the newly created, industrial-scale plant that PURPA dubbed “cogeneration” and the traditional, utility-scale power […]

It is fairly common for power plant engineers and maintenance managers to focus on fireside issues rather than waterside issues during routine maintenance outages. However, that could be a mistake. Waterside

Thermohydraulic simulations can provide detailed heat recovery steam generator (HRSG) data to help determine the root cause of failures, predict the degree of wear from various mechanisms, and assess the

Many combined cycle power plants have established a pH guideline between 9.6 and 10.0 to minimize corrosion in heat recovery steam generators and condensers. Neutralizing amines are used to achieve these pH

For a decade or more, heat recovery steam generator (HRSG) users have heard that Grade-91 tubing (T-91) is susceptible to microstructure damage from improper heat treatment. Now, a new damage mechanism in T-91 tubing has been identified, which HRSG users heard about at the February 2018 HRSG User’s Group Conference. During the discussion on heat […]

Finding the best place to sample heat recovery steam generator (HRSG) tubes isn’t as hard as finding a needle in a haystack (but it’s like that). Ask most HRSG users where they take their routine tube samples for monitoring under-deposit corrosion in the high-pressure evaporator, and they’ll tell you, “first row, because it’s the hottest […]

Innovative boiler and heat recovery steam generator (HRSG) designs are improving efficiency, reducing emissions, and lowering maintenance costs. Some well-proven technology, such as circulating fluidized bed

Per January 1st, 2018 Siemens has rebranded and renamed its full subsidiary NEM Energy into Siemens Heat Transfer Technology (HTT). Siemens HTT is a specialist in the field of Heat Recovery Steam Generators for power plants. After completing the functional integration, the name change of NEM is the next step in the integration process initiated […]

Today’s construction boom in the combined cycle/cogeneration sector is great news for suppliers of gas turbines (GTs), heat recovery steam generators (HRSGs), and engineer-procure-construct (EPC) services. But before this boom advances from artist’s sketches (Figure 1) to first fires, the designers of all those next-generation combined cycles should pause to reflect on the lessons learned […]
