A patented electrostatic separation process reduces the carbon content of fly ash to produce a low loss on ignition (LOI) product used as a portland cement replacement in concrete products. Additionally, a high carbon content product stream is produced and is returned to utilities to recover fuel value or to cement kilns as a fuel and raw material. Two processing facilities have been commissioned in Florida; one in Tampa and another in Jacksonville. Both installations also include a patented ammonia removal process that reduces ammonia content on the fly ash from levels of greater than 2000 ppm to levels less than 75 ppm. The Tampa facility includes three separators, an ammonia removal process, two concrete slip-form product silos and a 25,000-ton dome. The plant is capable of processing 350,000 tons of fly ash per year. The Jacksonville installation contains two separators and an ammonia removal process capable of processing 300,000 tons per year. Twelve (12) ash beneficiation facilities have been commissioned in North America, the United Kingdom and Poland along with two mineral processing facilities in Europe and Canada.","PeriodicalId":400797,"journal":{"name":"2013 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114454170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two types of relay testing which is performed on microprocessor-based protective relays: (1) commission testing and; (2) routine or periodic testing. Commission testing is extensive and exhaustive and its role is to completely test the design and installation of the protective system. Routine or periodic testing is used to validate that a protective system will perform its task by verifying the relay is measuring correctly, set correctly and that it will operate its output contacts for a fault or alarm condition. This paper will first review the differences and functions of commission testing and routine/periodic testing. Secondly, the paper will review methods to use the “smarts” of the microprocessor-based protective relay to detect issues during startup or during normal operation. These methods include protective relay setting comparison, minimal negative sequence current and voltage, verification/recognition of contact inputs, manual operation of contact outputs, complete control circuitry (trip, close, start, stop functions), lack of device self-test alarms, device date & time, and phasor diagrams provided by protective relay. Examples will be reviewed on the methods including an overview of symmetrical components. The paper will discuss options of installing test switches for AC current & AC voltage isolation and use of spare relay case or chassis for bench tests/verifications. In addition, the paper will discuss the periodic tests that should be performed on protective relay spares that are stored in an industrial facility's warehouse.","PeriodicalId":400797,"journal":{"name":"2013 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124830683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is imperative, in all production operations that downtime be avoided or minimized. If a motor problem does occur, the source of the problem needs to be promptly identified and corrected. With proper knowledge of the sources of motor vibration, proper vibration measurement and diagnostic procedures, it is possible to more quickly identify the root cause of motor vibration. This paper intends to assist the operators of cement plants in avoiding erroneous conclusions that may be reached as a consequence of not understanding the root cause of the vibration; conclusions that may result in trying to fix an incorrectly diagnosed problem, wasting time and money in the process. By utilizing the proper data collection and analysis techniques, the true source of the vibration can be more accurately determined: This analysis includes, but is not limited to vibration related to: · Electrical imbalance - stator, rotor bar · Mechanical unbalance - rotor, coupling, driven equipment · Resonance and critical speeds · Mechanical effects - looseness, rubbing, bearings · External effects - base, driven equipment, misalignment. This paper includes a diagnostic guide (Table I) listing of the causes of electrically and mechanically induced vibrations in large motors, along with the characteristics of these vibrations. In addition, a field example is provided from a cement plant facility wherein a vibration problem was discovered, the root cause was determined and the vibration issue was solved.","PeriodicalId":400797,"journal":{"name":"2013 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"18 26","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120824756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bypass dust is the dust that is rejected from a kiln system in order to lower the chlorine or alkali content of the produced clinker. Many cement plants have routinely landfilled this dust over many years. The strategic concept of \"zero waste\" is the basis for this system, but other smaller reasons also exist for its development: · The landfill disposal costs are high in some areas. · Bypass dust, which is typically wasted, has a unit cost of 20-30% of the cost per ton of producing clinker - depending on the cement making process type - and this cost can be recuperated. · For environmental reasons it may be beneficial to reduce the landfill area within the overall plant site area. · An increase in alternative fuels may cause an increase in bypass dust that needs to be extracted, thereby, causing higher disposal specific production costs. · The sales price of salt runs at approximately 350 USD/t which is potentially a new income stream for the plant. The dust reduction system is made up of the following sections: 1. Washing of bypass dust with water; 2. Filtration to obtain a salt solution (brine); 3. Chemical treatment (purification and conditioning of the brine); 4. Evaporation of this clean-neutralized brine to obtain the alkali-salts. The products of the system are: 1. Raw meal, low in alkalis and chlorine, that can be directly used as kiln feed. 2. High purity salts that can be used for food, de-icing roads, or making fertilizer. 3. Heavy metals sludge that can be treated separately to obtain valuable metals. A pilot plant has been installed with positive results and now the first industrial-sized plant is under construction.","PeriodicalId":400797,"journal":{"name":"2013 IEEE-IAS/PCA Cement Industry Technical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129919907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
