• Efficiency factors in natural gas fired steam boilers

    Assuming the boiler has 75 t/h capacity, high pressure steam is produced at 38 bar and 440°C which represents 59 Gcal/h of thermal power. When this boiler works at 90% efficiency, thermal power becomes 53 Gcal/h. Due to a high oxygen level in the boiler, a 1.4% loss in efficiency occurs and thermal power reduces by 0.74 Gcal/h to 52.3 Gcal/h.Learn More
