Cement Plant Conveys and Weighs “Green” Bulk Fuel Ingredients in Process to Replace Coal - Sponsored Whitepaper

LINCOLNSHIRE, UK — Castle Cement's Ketton Works replaced coal for firing of its rotary kilns, with Profuel™, an alternative fuel comprised of cardboard, paper, plastics, textiles, carpet and other "green" fuel waste materials. In 2002 the company built a £4-million ($7.56-million), three-stage Profuel preparation plant that required conveying and weighing of the Profuel material as well as pulverized fuel ash (PFA) that is heated along with calcium oxide, silica, aluminum and iron in horizontal rotary kilns at 1600°C (2940° F).
