Two efficiencies were calculated: 1) Gross Boiler Efficiency and 2) Plant Efficiency. The Boiler Efficiency was a simple calculation including only gross steam output BTUs per hour divided by the sum of coal + feedwater BTUs per hour. This efficiency remained constant at about 75% even as the boiler load was varied between 20% and 75% load.Get Price
