Germany-based FLSmidth Pfister GmbH, a member of Danish FLSmidth A/S, specialises in weighing and dosing technology for demanding industrial environments. With in-depth knowledge and inspired technical ideas, FLSmidth Pfister is the worldwide market leader for coal-feeding applications. FLSmidth Pfister is the inventor of the patented Pfister® rotor weighfeeder, the outstanding gravimetric dosing technology whose properties have proved their excellent reliability and accuracy in almost 2,500 installations worldwide.

Pfister rotor weighfeeders for the power industry

Pfister rotor weighfeeder's outstanding strength is their highly accurate and reliable gravimetric feeding ability for direct and indirect firing. With the rotor weighfeeder, Pfister TRW-K and rotor weighfeeder Pfister DRW users are able to dose a variety of materials such as crushed coal, petrol coke, coal dust or lignite to the boiler firing process. With its integrated pneumatic transport, rotor weighfeeder Pfister DRW is an ideal choice for leading-edge applications like feeding pulverised lignite (TBK) directly into the boiler burners.

What is special about Pfister rotor weighfeeders for coal power plants?

Pfister rotor weighfeeders work like horizontal star feeders. The gravimetric mass in the feeder is measured by a load cell. The speed of the feeder motor is controlled inverse to the mass content in the feeder. Less material in the feeder results in higher speed, more material in the feeder in lower speed. Powered by the state-of-the-art proactive control strategy ProsCon®, the flow rate is controlled allowing for great stability. This makes it possible to achieve the highest short and long term accuracy, even within a large feed range and a stable feed rate at the outlet.

Of course, all FLSmidth Pfister weighing and dosing equipment is certified according to international quality standards.

Pfister® rotor weighfeeders: almost maintenance-free

Pfister rotor weighfeeders have a compact, robust, fully closed, all-metal design. They are easy to install, self-cleaning, show negligible wear and are easy to maintain. Rotor weighfeeder Pfister TRW-K and rotor weighfeeder Pfister DRW are designed in an ATEX explosion-proof design.

All Pfister rotor weighfeeders require extraordinarily low maintenance during their entire lifetime, guaranteeing outstanding availability and cost efficiency. Nonetheless, FLS Pfister offers 24/7 technical assistance and online support.
