These generating units are critical to continuous mill operations. To avoid excessive utility power demand costs and for operations continuity of steam loads, turbine generator downtime must be kept to an absolute minimum. Consequently, at many mills with older, brush-type exciters, brushes are changed with the generator on-line. On-line brush changing is recognized by OSHA as a specific energized work task, with associated safety requirements and guidelines which are noted in the regulations. Both voltage and arc flash hazards for this DC system must be addressed to meet requirements of the 2004 edition of NFPA 70E, Standard for Electrical Safety in the Workplace. This paper describes a paper mill case study proceeding out of a hazards analysis of subject task with the goal of improving personnel safety through hardware enhancements, training and documented procedures. Specific improvements made to the collector housing system hardware, field ground relaying, over-current protection and alarming are noted and described in detail.","PeriodicalId":435177,"journal":{"name":"Conference Record of 2007 Annual Pulp and Paper Industry Technical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131941930","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 is a growing concern of a shrinking talent pool and a pending human resources crisis. There are several published papers that discuss strategies for educating and recruiting up and coming engineers. This paper, however, discusses the expectations and perspective on the job market from the point of view of recent engineering graduates. A survey was conducted of 30 near-graduate and recent graduates of various engineering disciplines asking their motivations for choosing their particular field. From experiences on a university campus, the most effective recruiters are those who actively go after students by: providing meaningful co-op/internship experience as well as by being involved with on-campus information sessions and events. Furthermore, the pulp & paper industry has unique challenges and opportunities with regard to adapting new technologies and the potential benefits to the environment. These attributes of the industry, if presented compellingly, can be used to more effectively attract young engineers.","PeriodicalId":435177,"journal":{"name":"Conference Record of 2007 Annual Pulp and Paper Industry Technical Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114097008","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}

Recent experience suggests the steep wave fronts increase the magnitude of the above electrical problems, leading to motor bearing material erosion and early mechanical failure. Until recently, bearing failures from shaft currents were predominantly electromagnetically induced. This paper presents three sources for bearing currents and under PWM operation can be both electrostatic and electromagnetic induced. A field methodology for identifying each source and recommended mitigation is presented. First, a brief history of bearing failures is discussed. Next, the application and a system model presented. An extensive field case study from several motor locations is presented following discussion of a methodology and bearing model found useful in field investigations. Field measurements are reviewed indicating both electrostatic and electromagnetic fields are induced within the motor. The measurements and installation details collected from the various sites quantify the variables that contribute to the different measurement results between motor locations. Effects of system components on shaft voltages and bearing currents are evaluated from field measurements and compared to theory. Quantitative results of solutions to shaft voltage and bearing currents are presented.","PeriodicalId":435177,"journal":{"name":"Conference Record of 2007 Annual Pulp and Paper Industry Technical Conference","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126733723","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}

A comprehensive summary of commercial activities in fuels (liquids and gases), bioenergy production, and the biorefinery are presented. There are substantial, commercial activities in North America but the large pulp and paper companies are not in the forefront of this activity. The only pulp and paper companies with commercial biorefinery activities tend to be the smaller or small independent pulp and paper companies. A comparison of the U.S. department of energy (DOE) funded projects with \"section 932\" grants is made. They show non-pulp and paper companies have considerable pilot experience and have the willingness to risk millions on scale-up for technologies valued by society (i.e., biomass to energy). This willingness gives the non-pulp and paper companies the opportunity to lead and develop technical and commercial experience at the plant scale. A new model will be needed by the pulp and paper industry if it is to avoid losing its historical place as the unquestioned leader in cellulose and lignin separations, conversion technology, and commercial distribution of forest-service products and materials.","PeriodicalId":435177,"journal":{"name":"Conference Record of 2007 Annual Pulp and Paper Industry Technical Conference","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115545736","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}
