Energy balance calculation is often done for designing a heat exchanger to determine operating parameters for hot and cold fluids such as - inlet / outlet temperatures and flow rates. For hot fluid side of a heat exchanger let, m H: mass flow rate of the hot fluid in kg/hr Cp H: mass heat capacity of the hot fluid in Joules/kg 0 C
principle based model of grate cooler for cement plant. In this work, the temperature variation and assumptions of the model will be discussed. The model is developed for steady state condition. Variations of gas, solid temperature, wall temperature and heat losses through the wall are simulated with respect to grate cooler length.
