Power Mills

Recognized Expertise

For nearly 100 years—ever since pulverized coal combustion was adapted for power generation—GE has been a leader in coal mill technology for the power industry. That leadership continues today with the world’s largest fleet of installed power milling equipment. Licenses for our milling technology can be found in all coal-powered regions of the world. 

Pulverizing solid fuel to powder enables its drying and transport for combustion in large furnace sizes. 

Fine grinding increases the fuel exposed surface area while simultaneously drying and controlling its distribution. These are integral steps to efficient, low emissions combustion which are optimized together with boiler thermal performance.

We design and continuously develop a complete range of milling technology that includes vertical spindle bowl mills and beater wheel mills, with classifier options to match our customers’ efficiency and fuel flexibility demands. 

Our mill and classifier portfolio can process all fuels commonly used for power generation and fuel blends, while maintaining excellent combustion efficiency under low emission conditions with reduced power consumption and maintenance requirements.

Leading mill technology

Wide fuel range capability, with the ability to handle all solid fuels suitable for power generation, from anthracite to lignite B.

Enhanced operational flexibility, handling fuel blends, transient operation, and load ramping, while supporting emissions compliance.

Reduced capital, labor, maintenance, and operating costs:

• Simple modular design that keeps capital and construction costs low
• Interchangeable modular components that reduce inventory costs and repair cycle time
• Unique construction concepts that allow mill installation without welding for reduced labor costs
