Unfortunately, after over 50 years of research, scientists don't expect a demonstration of full-scale fusion power generation in a prototype power plant until after 30 to 35 years. Extensive research, however, has made two significant advances in plasma physics, the discovery of bootstrap current and plasma's ability to organize itself in the edge at certain a pressure so that it is a much better insulator and retains heat much better. These advances have been very helpful in the development of the experimental fusion reactor ITER.","PeriodicalId":182274,"journal":{"name":"Power Engineer","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114257924","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}

The boilers are able to burn a wide variety of coals from all over the world, and they can burn up to 20% petroleum coke. This paper discusses how the pulveriser upgrades at the Florida generation site cleared the way for the burning of lower grade coal. Beginning in the spring of 2002, and concluding in the spring of 2005, the plant upgraded its combustion equipment to lower NOx, CO, and LOI and positioned itself more favourably for future compliance with the Clean Air Interstate Rule. This work included advanced low-NOx burners, windbox modifications, an aerodynamic over fire air system, coal pipe orifice valves, and a permanently-installed microwave-based coal flow monitoring system. This effort was highly successful in obtaining the desired emission reductions and had the additional benefit of allowing the plant to increase petroleum coke consumption.","PeriodicalId":182274,"journal":{"name":"Power Engineer","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116779540","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}

The result has been to leave the power station with a reduced risk of failure in the future given the ability to have one transformer out of service while generating through the other unit.","PeriodicalId":182274,"journal":{"name":"Power Engineer","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132670093","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}

BPL provides utilities with benefits beyond additional revenue. The same system that transmits Internet data can be used to remotely monitor household electricity usage, eliminating the need to send a technician out to inspect the household meter. The system can also provide detailed feedback on electricity usage in real time, which could potentially detect brownouts before they escalate into blackouts. For home and office broadband users, the ubiquity of power lines offer services that were not available to many in remote areas. For broadband users in the urban areas, additional choices mean competitive prices and better services.","PeriodicalId":182274,"journal":{"name":"Power Engineer","volume":"147 Pt 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126310677","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}

Fortunately, an array of products is available to handle real-world challenges of high power densities and cooling in IT environments. Data center outsourcing is another option that is growing in popularity among businesses.
