Coal Feeders

The Greenbank Group partners with Merrick Industries Inc to offer their customers the best in coal feed systems and diffusers. Merrick enjoys one of the best known brand names in the industry and has long been associated with quality engineering.

Merrick’s gravimetric, rubber belt, pressurized coal feeder is arguably the most reliable, accurate and cost-effective means of feeding raw coal to pulverisers in use today.

This low pressure feeder provides uniform and precise fuel delivery by weight to the combustor, with an accuracy of plus or minus 0.25% of total delivered materials weight.

Made from ¼ inch thick carbon steel shell, the coal feeders are robust, allow long life operation and operate dust-tight at pressures of up to 3psig. (0.2 bars)
