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).
A mathematical model of rotary kiln incinerator was developed.The model performs both heat and mass balances and heat transfer analyses in a rotary kiln combustor.
A more rapid estimation of this heat can be done by using a formula developed by Zur Strassen (1957) which gives good agreement with basic calculations.59F Where Qth = theoretical heat of the formation A, M, C, S and F are the percentage of AW3, MgO, CaO, SiO2, and Fe2Os in the clinker.
A precalciner kiln system is the basis for this study.It normally consists of a preheater, a precalciner (also known as a calciner), a rotary kiln and a cooler.The raw meal) is heated in the preheater and then sent to the precalciner where typically 85-95% of the calcination takes place.
A rotary kiln is a cylinder slightly tilted (a few degrees) with respect to the horizontal and which rotates around its axis (Figure 1).The material to be processed (typically grains) is fed into the upper end of the cylinder (the Figure 1.Sketch of a typical rotary kiln.
