FLSmidth Pfister rotor weighfeeders and ProsCon are the innovative solution for stable metering of solid fuels.
The company's rotor weighfeeders offer highly accurate and reliable gravimetric feeding for direct and indirect firing and dosing of a variety of materials, such as crushed coal, pulverised coal or lignite dust, alternative fuels and biomass, limestone meal orhydrated lime.
FLSmidth Pfister's patented rotor weighfeeder technology has proved its reliability over 25 years and through more than 2,300 successful installations across various application fields worldwide.
The robust and wear-resistant design makes the system extremely reliable. Powered by the state-of-the-art proactive control strategy ProsCon, the flow rate is precisely controlled. The high-performance electronics ensure precise material-feeding into the firing or dosing proccesses thanks to its special control algorithms. This makes it possible to achieve the highest short and long-term accuracy, even within a large feed range.
FLSmidth Pfister rotor weighfeeders are fully closed, dust-tight and can, if necessary, be manufactured in an explosion-proof design. All Pfister rotor weighfeeders require extraordinarily low maintenance throughout their entire lifetime.
When all these facets are taken together, it means FLSmidth Pfister rotor weighfeeders can guarantee outstanding availability and efficiency throughout their entire lifetimes.
With its integrated pneumatic transport, the Pfister DRW rotor weighfeeder is the only choice when it comes to the new application of feeding pulverised lignite (TBK) directly into the boiler burners.
