    Boiler Efficiency | How to balance steam loads efficiently

    Aug 26, 2011· The heat losses are less at higher loads. If we consider the additional boiler duty and the additional fuel input for this additional steam generation, the HRSG comes out a winner hands down. At 50% load, the steam generation is 50,000 lb/hr, and additional boiler duty is 24.9 million Btu/hr compared to the unfired condition.
