B&W Parts, Services and Programs for CE-Type Pulverizers / Mills
B&W applies our vast experience and knowledge of roll wheel and ball-and-race pulverizers to provide quality replacement parts, services and inventory management programs to Combustion Engineering (CE)-type pulverizers.
Since 1867, B&W has set the standard for proven high availability, reliability and low maintenance on its boilers, pulverizers and other steam generating and auxiliary equipment. We remain invested in coal and will continue to provide quality products and services to keep the fleet of coal-fired power generators operating reliably, efficiently and with high availability.
