🔥 Triple-Pressure Reheat HRSG (Pinch Point 15°F & Approach Temp 10°F), Steam Lbs/Hr

HRSG Pinch & Approach Temperature Calculator

Size multi-pressure Heat Recovery Steam Generators (HRSG) behind gas turbines in combined-cycle power plants under ASME Section I: calculate High Pressure (HP), Intermediate Pressure (IP), and Low Pressure (LP) evaporator pinch points (15°F to 20°F delta between exhaust gas and saturated steam) and economizer approach temperatures, and HRSG contracting margins.
