There are no technical areas that have not improved significantly due to developments in the last decades to reach the targets mentioned above. This applies to the use of the high voltage, medium voltage and low voltage switchgear and the breaker installed, as well. The ever increasing electric demand has propelled the growth of electrical systems where an associated rise in short circuit has increased the demand for high transformer, interrupting breakers, and switchgear ratings. Technically, the breaker technology, and especially the switchgear families applied today, are very different from those used in the past. The paper describes in detail the different types of switchgear technologies and its breakers that can sustain the higher ratings without compromising the reliability and security of the switchgear and their typical application in today's cement plants, based on a common way of engineering. The paper also provides information on the environmental implications of the different switchgear solutions, and illustrates the differences for consideration. The very important issue of the maintenance and upgrading of old technically-obsolete switchgear, is treated with practical suggestions and recommendations. Finally, the issue of standards and how they are applied to switchgear in the globalize world, were treated as well. The paper closes with the answer to a very interesting question; \"What will be the future of switchgear and breaker technology, and in which direction will this technology move forward?\"","PeriodicalId":396587,"journal":{"name":"IEEE Cement Industry Technical Conference, 2006.

There are a number of methods that may be adopted by plants to achieve these mutually competing goals. One of these is implementation of low-NOx calciners, which cause a portion of the calciner fuel to be burned under sub-stoichiometric (low oxygen) conditions - this method causes combustion under conditions which will suppress generation of fuel NO x from the calciner, and may also cause decomposition of some of the NOx (thermal and fuel) produced in the rotary kiln. Another method is selective non-catalytic reduction (SNCR) of NOx using ammonia or urea. This latter method, when injected in the proper range of temperature, excess oxygen, and possibly carbon monoxide, has the advantage of compatibility with oxidizing conditions in the calciner, which will often minimize or avoid buildup difficulties associated with movement of sulfur as SO2 within the preheater. The most efficacious combination of one or both of these methods may be one of the best approaches available to control NOx emissions for new and existing kiln systems, while simultaneously avoiding excessive emissions of CO or SO2 and reducing the process problems associated with sulfur cycles","PeriodicalId":396587,"journal":{"name":"IEEE Cement Industry Technical Conference, 2006.

Continuous on-line XRD analysis at the cement mill outlet has been tested to directly control calcite addition, SO/sub 3/ content, gypsum hemihydrate and pozzolan addition. Furthermore, the information that XRD provides is used to generate models that predict strength. As such automatic control of cement strength may be achievable in the near future. XRD is a common analytical technique used to directly measure the mineral content of cement, such as C3S, C2S and gypsum. The technique is highly developed and able to detect most cement minerals, even distinguish between the different phases of aluminates, belite and gypsum for example. While XRD is often carried out in a laboratory, a number of plants have installed a field instrument, which analyzes a continuous stream of material in real time. The field instrument employs a special patented position sensitive detector that allows for a full mineral analysis of a moving stream of material to be trended in real time continuously, giving the information needed for real time automated plant control. In contrast, laboratory units analyze a small sample specimen over a finite time to give an analysis. The principles used to determine mineral composition in an on-line XRD machine are no different to those used in laboratory machines. However, the volume and timeliness of the data from an on-line instrument allow for the control of certain quality parameters in real time. An on-line XRD can avoid sample preparation problems by examining a vast number of crystals in a continuous sample presentation system. This article describes a technology for on-line XRD analysis, and how it can provide benefits to cement and clinker production.","PeriodicalId":396587,"journal":{"name":"IEEE Cement Industry Technical Conference, 2006.
