Pulverizers

Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW. B&W's pulverizers, found at power stations throughout the world, use an optimized design, reserve capacity and proprietary wear materials that set the standard for high availability, reliability and low maintenance.

Every B&W pulverizer is built with a commitment to quality, durability and operational excellence:
• Operates a minimum of 3,000 hours between internal inspections
• Maintains fineness and capacity throughout the wear life of the grinding elements
• Accepts and grinds a wide variety of coal types
• Requires a minimum number of replacement parts
• Allows for easy maintenance through a single, large access door
• Includes capabilities to manually or automatically change spring loading and/or coal fineness
• Utilizes the most advanced wear and erosion protection

Today, with more than 1,100 B&W Roll Wheel pulverizers sold worldwide and six different sizes burning a variety of coals, B&W has the proven design and operating experience to meet your specific project requirements. This performance has made the B&W Roll Wheel pulverizer the pulverizer of choice for coal-fired boiler operators and owners.
