🏭 Combined Cycle HRSG (Evaporator Pinch Point 15°F-25°F, Approach ΔT & Steam Lbs/hr)

HRSG Pinch Point & Approach Calculator

Size unfired and duct-fired Heat Recovery Steam Generators (HRSG / Nooter Eriksen / Vogt) capturing turbine exhaust gas heat: calculate evaporator pinch point temperature difference ($15^circ ext{F to }25^circ ext{F}$), economizer approach temperature ($Delta T ext{ } 10^circ ext{F to }15^circ ext{F}$ preventing steaming in economizer tubes), high-pressure steam generation (Lbs/hr), and boiler margins.
