Marine Boiler What Affects Its Performanceefficiency
Performance of Boiler: Effiency, Power and Heat Balance Sheet May 12, 2020 · The performance of boiler is measured in terms of its evaporative capacity. However, the evaporative capacities of two boilers cannot be compared unless both the boilers have the same feed water temperature, working pressure, fuel and the final condition of steam.
