Medium pressure gravimetric feeder for pulverized coal boilers
Achieve precise combustion control and optimize fuel efficiency in your coal-fired power systems with this medium pressure gravimetric feeder, specifically engineered to handle explosive environments safely and efficiently manage your fuel flow.
Feeds Pulverized Coal for Consistent Combustion
The MULTIDOS MPG Medium Pressure Gravimetric Feeder from Schenck Process Europe GmbH is engineered to meet the rigorous demands of coal-fired power plants and other industrial applications. Designed for environments that require feeders to withstand explosion pressures up to 1 barg, it ensures safe and accurate coal feeding by maintaining flow accuracy within ± ½ of 1 percent. Ideal for use in pulverized coal and combustion control systems, it supports improved boiler efficiency and emission reductions by facilitating precise air/fuel ratio management.
With a standard conveying length of 2134mm and inlet sizes available in 610mm or 914mm, the feeder accommodates diverse feed rates up to 100 tons per hour. Automating continuous high-speed operations, it integrates seamlessly with existing control systems, enhancing operational efficiency. The MULTIDOS MPG’s robust build and adaptability make it essential for coal-fired and biomass-fired power plants, steelmaking, and cement industries aiming for optimized fuel use and emissions control.
