Heat balanceis an important exercise in all high temperature processes. Heat balance can be used to determine the temperature, theoretically, which can be attained during roasting. Knowledge of temperature is useful to take a decision about the refractorymaterial.
Heat balance
At unsteady state
Heat input=Heat output +Heat accumulation +Heat losses
Inhightemperature processes, certain amount of thermal energy is retained within the reactor to maintainprocessing temperature. At steady state and at constant temperature.
