This process control has evolved over the years; from the well-trained eye of a seasoned kiln burner to the dual imaging pyrometry technology used to continually monitor cement kiln burning zones. This device easily integrates into any of today's sophisticated control systems, and quickly becomes a critical link in establishing a control strategy for kiln operation. This paper spotlights the installation and operation of three Spyrometer/sup TM/ systems at Medusa's Wampum facility (USA) during the plant's 1995 automation project. The camera's microprocessors link directly to the remote I/O racks of the new PLC-based control system. So they not only provide a continual window into all three burning zones, but they monitor six temperatures at operator specified windows. These inputs can also be used as a BIF regulated waste fuel interlock or as an expert system control parameter. The data generated from the pyrometer's temperature measurement can also be used in an effective clinker quality control program. By coupling clinker microscopy and cement physical testing with the trended data, tangible performance improvements are demonstrated for not only the product, but with the process operation.","PeriodicalId":443254,"journal":{"name":"1997 IEEE/PCA Cement Industry Technical Conference.

Plant control is distributed over forty PLC5s with over eighteen thousand I/O points, which have been installed over ten years. The kilns were the last major pieces of equipment yet to be tied into the PLC based supervisory system. PLC5s were chosen for the kiln automation based on this installed base and on the ease of expanding the existing supervisory system network to accommodate the kiln control. The plant architecture uses three layers of communication: first, remote I/O to communicate to the I/O subsystem from the PLC Processor; and secondly, a Data Highway Plus to communicate between processors and to the Ethernet gateway/data server. This gateway provides process data to the third layer, the process supervisory network. The process supervisory network consists of supervisory workstations running Intellution DMACs and the expert system LUCIE which is Lafarge's own application running on Gensym G2. This paper discusses the design and installation of a DeviceNet communication network to smart motor control centers (MCCs) on the three kilns at the Alpena plant. The DeviceNet link, which provides direct digital control and monitoring of motors, is linked to the supervisory system via the remote I/O link.","PeriodicalId":443254,"journal":{"name":"1997 IEEE/PCA Cement Industry Technical Conference.

Using partial discharge measurement technology to implement predictive maintenance in high voltage motor and generator stator windings 采用局部放电测量技术对高压电机和发电机定子绕组进行预测性维护

A deteriorated winding has a PD activity which can be 30 times or more higher than a winding in good condition. This great difference in PD activity enables even nonspecialized maintenance personnel to identify the few motors or generators in a company which need further investigation and/or maintenance. After implementing on-line partial discharge tests companies can often confidently extend the outage between major machine inspections. This saves on outage costs and reduces the risk of a stator fault due to human error during maintenance. Finally, on older machines, if there has been no increase in partial discharge activity over time, then the life of the stator winding can be confidently extended, saving a considerable capital expenditure. The PD tests discussed cost virtually nothing to perform, once the sensors are installed, since existing company staff can do the tests in about 30 minutes during normal motor or generator operation.","PeriodicalId":443254,"journal":{"name":"1997 IEEE/PCA Cement Industry Technical Conference.
