The term cement includes a range of substances utilized as binders or adhesives even though the cement produced in the greatest volume and most widely used in concrete for construction is Portland cement. Cement plants basically consist of three manufacturing parts i raw material and fuel supply preparation ii clinker production commonly named as the pyroprocessing part and iii intergrinding and blending of cement clinker with other active ingredients to produce the required types of cement.
The cement manufacturing process starts by handling a mix of raw materials i naturally occurring limestone which is the source of calcium ii clay minerals and iii sand which are the sources of silicon and aluminium and iv iron-containing components. The raw materials are ground and mixed together in controlled proportions to form a homogeneous blend termed as a raw meal or raw-mix with the required chemical composition.
A simplified block flow diagram BFD of the MCC plant with focus on the rotary kiln system is presented in Figure 2. It consists of the few most important subsystems illustrated as a single block in the figure which performs the specific technological operations in cement manufacturing. A short explanation of BFD and a description of the subsystems and main material streams that are shown in Figure 2 follows.
Simulation of the kiln system in this study considered the following chemical reactions for the processes of clinker formation
The parametric studies generate vital information for evaluation of cement kiln system production processes. Thus the parametric analysis could be used to improve kiln system performance and evaluate environmental performance of the plant due to emissions arising from physiochemical reactions.
From the thermodynamics of combustion of rotary kiln systems point of view increasing coal flow rate raises burning temperature as well as clinker production rate. However increasing the fuel flow rate at stoichiometric conditions reduces the flame temperature 52. In order to maintain the flame temperature fuel and air flow rates are varied proportionately 1. The results from Figure 5 suggest that the maximum temperature of is achieved at . By increasing beyond 5580Ckgh-1 flame temperature decreases to 1660C at stoichiometric air.
Moreover Figure 5 indicates that increasing the coal flow rate above an optimum value will lower combustion efficiency which is indicated by an increase in carbon monoxide CO. This is explained by the fact that increasing the coal flow rate at a constant supply of combustion air results into a dramatic decrease in O2 as indicated in the same figure. The decreases in O2 in turn result into the incomplete combustion of coal.
Traditionally rotary kiln burning operation control is done by the adjustment of the raw feed fuel flow rate and ID fan speed. However oxygen target level is very important not only for the complete combustion of fuel but also for better clinker burning conditions.
