Energy balance and cogeneration for a cement plant
An enthalpy balance for the system is drawn, taking the reference enthalpy to be 0 kJ/kg at 0 °C, 1 atm. The specific enthalpy of various components is obtained from Peray [6].The temperatures of the streams are measured and the calorific value of coal is obtained from the plant data (Fig. 2).The energy required for the reaction has been …

EVERY THING YOU NEED TO KNOW ABOUT HEAT BALANCE IN CEMENT …
A heat balance, simply stated, consists of compiling all the heat that is given to the kiln and then comparing this total to the total of thermal work done and heat losses that occur in the system. Whatever heat put into the kiln (INPUT) must be accounted for in one way or another by the heat that goes out of the system (OUTPUT).
