heat balance in cement kilns


EVERY THING YOU NEED TO KNOW ABOUT HEAT BALANCE IN CEMENT KILN

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).
