The production increase was accomplished by converting the existing in-line calciner to a separate-line down-draft calciner system, retrofitting all preheater stages to a low-pressure design, and making modifications to the existing vertical raw mill. Production and fuel consumption guarantees were met and the system operates with superior performance and reliability. This paper explores Capitol Cement's recent expansion project and identify the relevant system design and start-up issues. Capitol Cement has proved to be a pioneer in implementing emerging technologies, with the end result being that the upgraded dry line is presently one of the most modern kiln lines in the United States. Innovative features such as a down-draft calciner (DDC), a two-channel calciner burner, and a SO/sub 2/ reduction system (D-SO/sub x/) is presented. Interestingly, the SO/sub 2/ reduction system uses a portion of calciner exhaust gas to absorb volatile sulfur compounds from the upper-most preheater stages and thereby prevent their release into the atmosphere. This technology, and others, are presented in the context of the overall project execution.","PeriodicalId":412513,"journal":{"name":"IEEE-IAS/PCA 2001 Cement Industry Technical Conference.

Corrosion is caused by acid attack on carbon steel, resulting from the presence of acid producing compounds in raw material, fuels and additives. These compounds typically contain sulfur and chloride. However, weak acids such as carbonic acid can cause slow corrosion over a long period of time. The costs of baghouse corrosion include: repair of tube sheets and bag collars; repair of walls/hopper; cost of new, replacement dust collector; kiln downtime; bag replacement; environmental permit noncompliance fines; reduced production; personnel morale due to unpleasant task of bag replacement; safety hazards; and management distraction from making cement This paper explores the causes and costs of cement kiln baghouse corrosion. Typical system arrangements are discussed with a focus on identifying key problem areas for each unique system. Ways to identify the cause of the corrosion as well as strategies to reduce corrosion are elaborated on. Finally, four case studies are discussed to detail real world problems and solutions.","PeriodicalId":412513,"journal":{"name":"IEEE-IAS/PCA 2001 Cement Industry Technical Conference.

This optimization implies the factory be controlled and managed as one integrated entity, where all operations and factors affecting production are managed in such a way so as to maximize production within business, quality and operational constraints. A key to achieving this objective is the use of advanced technology, specifically intelligent control systems (ICS) that allow for the embedding of process, business and other knowledge so that the interaction and consequences of all events and states on the plant can be understood and taken cognizance of. Such intelligent automation systems have been installed on a number of plants within the PPC group in South Africa. These systems provide an intelligent and unified view of the total plant where most operations are controlled and managed from the same console. This includes all basic and advanced process control process optimization, as well as logistics. Because such systems are continuously being upgraded and expanded, they are always relevant, up to date, and keep up with the changing needs of the cement company, always adding value.","PeriodicalId":412513,"journal":{"name":"IEEE-IAS/PCA 2001 Cement Industry Technical Conference.
