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).

Assessment of waste preheater gas and dust bypass systems

In dry kilns, raw mix with low moisture content (e.g. 0.5%) is used, reducing the need for evaporation and reducing the length of the kiln. The raw mix is fed into a combined preheater and precalciner apparatus, which heats and partially (nearly completely) calcinates the raw mix before it reaches a rotary kiln , .The calcination process involves the thermal decomposition of calcite and other

This also has an impact on the efficiency and capability of Zone Control. By balancing the heat in the chamber to start, Zone Control does not have to work as hard. You have less cycling (zones turning on and off to balance the heat) and when the kiln does need to cycle the power, it is distributed efficiently into the areas that need it the most.
