    Performance of Boiler: Efficiency, Power, Heat Losses and Heat …

    Now we shall discuss the third object, i.e. to prepare the heat balance sheet. Heat Losses in a Boiler . We know that the efficiency of a boiler is the ratio of heat used in producing steam to the heat released in the furnace. Also, heat utilised is always less than the heat liberated in the furnace. The difference of heat liberated in the furnace and heat utilised in producing steam is known as heat loss in the boiler. …
