Frequently Asked Questions (FAQs)
Heat Recovery Steam Generators are essential for increasing thermal efficiency in combined-cycle and cogeneration power plants. Explore these FAQs to better understand HRSG functions, integration with combustion turbines, maintenance needs, and Emerson’s role in optimizing performance and compliance.
An HRSG is a unit operation that captures waste heat from a combustion turbine’s exhaust and uses it to produce steam, improving the overall efficiency of power generation in combined-cycle or combined heat and power cogeneration process.
HRSGs allow gas-fired power generation plants operating in hybrid or combined-cycle modes to increase efficiency by utilizing otherwise wasted heat energy from turbines to generate additional power.
Key HRSG components include economizers, evaporators, superheaters, drums, and duct burners. These parts work together to convert turbine exhaust into usable steam.
Efficiency is typically measured by how effectively the unit converts exhaust heat into steam, which can be further improved with supplementary firing and optimized control systems.
While HRSGs themselves don’t burn fuel, the gas turbine exhaust they recover may contain NOₓ, CO, and other pollutants. Emissions control systems like SCR units are often integrated.
Emerson provides advanced control systems, instrumentation, and analytics platforms that help natural gas power plants improve HRSG reliability, thermal efficiency, and emissions compliance.
