Calculations of Heat Transfer in the Furnaces of Steam Boilers …

Heat balances are used in engineering for the analysis of thermal processes occurring in, for example, steam boilers, furnaces, and heat engines. A heat balance may be expressed in units of energy, such as joules or calories, or in percent of the total amount of heat per unit output, per hour of operation, per time period (cycle), or per kilogram of material used.
