I have to audit thermal efficiency of cement kiln system. I''ve made mass and heat balance for that system. Heat inputs consist of raw mix heat, air heat, coal heat, and coal combustion heat.
the mere calculation of energy efficiency of cement kilns remains important and necessary, a broader view reflects energy recovery, material recycling, fuel quality and actual and potential recovery of waste heat.
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).
Apr 02, 2019· The purpose of this study is optimizing the air and fuel quantities at kiln considering design parameters of the cement plant by keeping adequate safety factors at each level of calculations to assure that neither production rate nor quality of the clinker vary. Analysis of Heat balance was used to determine the sources of heat loss from the kiln system.

However, new cement kilns are of the ''dry process'' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the preheater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the ...
