Medium pressure gravimetric feeder for pulverized coal boilers
For industrial environments using pulverized coal-fired boilers, achieving precise control of coal feeding is critical. The challenge lies in ensuring accurate coal flow rate to optimize combustion efficiency while adhering to stringent safety standards.
Ensures accurate and safe coal feeding
The MULTIDOS® MPG Medium Pressure Gravimetric Feeder by Schenck Process is designed for pulverized coal-fired boilers needing feeders that can withstand explosion pressures up to 1 barg (14.5 psig) as per EN 12952-9 standards. With a standard conveying length of 2134mm (7’) and a 610mm (24”) inlet, it maintains coal feeding accuracy within ± ½ of 1 percent. This high accuracy results in more precise control of excess air, minimizing NOx emissions and enhancing overall combustion stability. The MPG series facilitates optimal air/fuel ratios, ensuring constant coal flow from the pulverizer to the burner. It accommodates varying coal conditions to provide reliable and consistent coal delivery, thereby improving boiler efficiency.
