Abstract:
Cement manufacturing requires cooling down of hot clinker at temperature of about 1350o C to temperature lower than 100 o C in a cooling system known as clinker cooler. Many plants are unable to cool the clinker below 250o C. This challenge led to scaling down of actual clinker cooler to a test rig size in the ratio 25:1 suitable for simulation. Computational Fluid Dynamics (CFD) tools (Solid-Works and ANSYS) were used to achieve the simulation. The clinker outlet temperatures obtained from simulations were validated with theoretical evaluation. Results showed that with clinker and cooling air flow rates of 0.2 kg/s and 0.54 kg/s respectively and with a clinker bed height of 0.6 m. An optimum cooler performance was achieved with clinker outlet temperature of 68 oC. The scaled down cooler was 15% higher than the existing cooler in terms of recoverable energy and 10% high in terms of energy efficiency. Keywords: Clinker Cooler, Computational Fluid Dynamics (CFD), Mass flow rate clinker and Mass flow air and Clinker Furnace.

Abstract:
Several parameters affect the properties of Portland cement and one of these parameters is the cooling rate of the clinker. If the effectiveness of the cooling method of the clinker increases, a good enhancement in the properties of Portland cement will be found. Depending on the new cooling method suggestion by Nasr et. al. [20], the counter pattern of air clinker flow was studied using (FLUENT 6.3.26). The dimensions of the cooling room in grate cooler, the constant mass flow rate of both clinker and air, different height ratios, and different clinker porosity were considered in this numerical work. The results show that the heat transfers in the first half of the cooling room (0 < X < 0.9 m) is larger than that in the second half (0.9 < X < 1.8 m), and this leads to an increase in the temperature of outlet air so can benefits from it in the heating of furnace. When the clinker and air are flowing in the counter direction, the cooling method is more beneficial when compared with that of parallel flow because the exiting clinker has a great rate of cooler and the air exits from the grate cooler is loaded with large thermal energy. Finally, it can design the best length of gate according to the required clinker temperature at the outlet side, and this results to reduce the cost of the cooling process according to the temperature distribution results at (0 < X > 1.8m) for different porosity and H.R values.

Abstract:
Discrete Element Methods have been used extensively in processes involving flow behavior where modeling the individual particles is of particular interest. A rotary cooler is an application of one such process. Although the current analysis can be used to any type of rotary cooler or rotary dryer, this work is focused on the analysis of particles falling from lifters in a planetary rotary cooler used in the production of clinker and installed at the outlet of a rotary kiln. Clinker is the main raw material used to manufacture cement. The objective of this work is to model the particle distribution inside the equipment due to different types of lifters and process conditions. Some of the parameters evaluated demonstrate that the tangential restitution coefficient and the Young’s modulus do not influence the results. However, a rolling friction coefficient on the order of 10-3 is required to represent a real operating condition. The results produce cascading similar to that of experimental observations reported in literature. Both our results and previously reported data display two distinct areas in the rotary drum, one mainly composed of material (the curtain area) and the other lacking material (the air area).

Abstract:
The numerical model was established to simulate the gas flow and heat transfer in cement grate cooler. It is useful to increase the gas temperature when the extracting exit position is close to the cement kiln end. The appropriate position of the extracting high temperature gas is about 5 m far away from the cement clinker inlet.

Abstract:
The report investigates the feasibility of accessing waste heat at kiln 7 in the Cementa AB cement plant in Slite, Gotland. The background is provided, with a description of the cement manufacturing process. Most of the report concerns itself with the heat transfer capabilities of the plant, therefore a short description of the heat flow within the most essential equipment is provided. The investigation follows a set of steps to derive the conclusion. The first step investigates previous studies to obtain the three most feasible heat sources. The second step investigates the available heat of the selected sources. In the third step, accessing the source is discussed and investigated for both convection and radiation heat transfer methods. It also includes the sizing of the required heat exchangers. Using the new sources, the connection possibilities to existing infrastructure and its benefits are investigated in step four. The connections were made to the existing infrastructure used at kiln 8 for electrical generation and district heating supply. The selections of the most feasible solutions are provided based on heat recovery, payback period and practicality. The final step in the study provides for the final design, which consists of three possible connections or all of them combined. In the conclusion, the final design would provide for a reduction in oil burned, fuel consumption and CO2 emissions and an increase in electricity generated by the existing system. It is recommended that only one of the three connections be installed.

The thesis was conducted at Cementa AB in Slite, Gotland. The supervisor at the plant was Fred Grönwall.

Abstract:
Abstract A dry-type Cement Production Plan of 151 Tons per hour was taken as a case of study to implement an exergoeconomic analysis. In this paper, the exergy destruction and the investment costs of the system’s units were calculated to obtain accurate information about the performance of the process, from the exergoeconomic factor and the relative difference cost. Conventional exergoeconomic analysis showed that the total cost of exergy destruction is 4206537 USD/h. The Calciner and the Rotary Kiln cause 62% of the total cost of the exergy destruction. The lowest values of the exergoeconomic factor were calculated for Calciner (0.01%), Clinker Cooler (0.01%), Rotary Kiln (0.02%), and Raw Mill (0.04%). The significant difference in relative cost was calculated for Calciner (42%) and Rotary Kiln (54.21%). The above implies that this equipment should be considered for an investment that allows the decrease of the exergy destruction cost and the increase of the exergetic efficiency.
