Production of Hydrogen - Stanford University

14 Current Technology Steam Methane Reforming (SMR) zLimitations – Carbon formation at low steam; carbon ratio – Higher hydrogen pressure limits CH 4 conversion – High CH 4 conversion requires high temperature – Excess steam production – Cooling by waste heat boiler to limit Bouduard

Combined Cycle Power Plant - an overview | ScienceDirect Topics

Combined-cycle power plants ( Fig. 2.3) are compound gas turbine–steam turbine systems wherein the extreme hot exhaust from a gas turbine is employed to run a boiler, and the steam thus produced is fed into a steam turbine to generate power. These plants can deliver high power output at efficiencies as high as 50%–60% with low emissions and
