Cogeneration, also referred to as combined heat and power, is the simultaneous generation of two forms of useful energy from one energy/fuel source. A cogeneration concept has been considered due to the coincident electric power and thermal loads present at cement manufacturing operations. For this application, a natural gas fuel source would be used to generate both electric energy and heat in the form of turbine exhaust gases. The purpose of this document is to advise cement manufacturing facilities of the potential of cogeneration, and present a concept of how cogeneration could be implemented. This document also defines the pertinent economic drivers and determine how project feasibility is affected. Major cogeneration plant equipment and systems are described. Feasibility for a test case, which considers installation of a nominal 13 MW gas turbine, is presented.","PeriodicalId":103359,"journal":{"name":"IEEE-IAS/PCS 2002 Cement Industry Technical Conference.

So it is the case for information systems. On both the business administration and the production information systems, there is a strong push for tighter integration in order to cut down on overlaps, multiple instances of similar data, expensive maintenance and so on. Excitement alone for (isolated) point solutions is just not enough. The value of a point solution nowadays is only appreciated, if it fits the larger picture of the total enterprise IT strategy. In the real world, it is not economically viable to replace all systems at the same time to the latest and same technology platforms. Technically this means that the focus shifts to ensuring consistency of information throughout a heterogeneous landscape of production information systems and business systems. In production management, production accounting is a tedious manual activity in reporting balanced production figures. There are imperfections such as sensor errors, limited measurement accuracy, calibration drift, transient accumulation, roundup, spillage and incomplete calculation. Production figures inevitably require reconciliation and balancing before finalizing month-end closing. This paper also shares the experiences and benefits of a large cement producer in the implementation of modern, integrated solutions across multiple plants.","PeriodicalId":103359,"journal":{"name":"IEEE-IAS/PCS 2002 Cement Industry Technical Conference.

Dealing with motor winding problems caused by inverter drives 处理由变频器驱动引起的电机绕组问题

Studies show that the failure is due to a combination of bad luck in specific motor installations (resonance phenomena caused by power cable length and surge impedance ratios) together with the fact that modern inverter-fed drives (IFDs) create tens of thousands of surges per second with rise-times as fast as 50 ns. Measurements on motors show that these surges create partial discharges (also called corona) and these discharges may eventually destroy the turn-to-turn and/or phase-to-phase insulation, resulting in premature motor failure. The paper discusses the specific mechanisms involved in the stator winding failure due to IFDs and present the measurements and analysis from surge monitoring installed on many different motors. Although some motors may experience short rise-time, high magnitudes surges, most motors experience either low magnitude and/or long rise-time surges, which are relatively harmless. Usually, several different magnitudes and rise-times are present from the same IFD. Thus, it seems that conventional motor stators can be safely used in many (but not all) IFD applications. Methods are presented to determine when special IFD duty motors are needed. Voltage surge tests, as well as partial discharge tests, can help the user insure that motors can successfully operate in severe applications.","PeriodicalId":103359,"journal":{"name":"IEEE-IAS/PCS 2002 Cement Industry Technical Conference.

To achieve this capacity increase of almost 90%, extensive additions and modifications had to be made in almost all manufacturing areas. These main areas were the quarry stockpile stacker and river load out conveying, a new higher capacity rock barge fleet, upgrades to the limestone unloading conveying system, limestone storage, raw meal transport, kiln feed system, pyro-process system, coal grinding, clinker handling, finish grinding system, cement storage and barge loading system, an addition to the main electrical substation and a new plant wide control PLC/HMI automation system. The paper describes the many challenges to execute this unique project in tight and restricted areas while at the same time maintain ongoing plant operation. Only a three month general plant shut down was scheduled for demolition and replacement of the existing gyro-process equipment and tie-ins of the various areas into the existing systems. Due to the time constraints this paper concentrates mainly on the pyro-process area.","PeriodicalId":103359,"journal":{"name":"IEEE-IAS/PCS 2002 Cement Industry Technical Conference.
