fly ash handling
Vacuum Extraction System
 
   
MBPL’s product profile includes Vacuum Extraction System for extraction of fly ash collected at Air Pre Heater/Electrostatic Precipitator hoppers of PF type boilers. Vacuum Extraction System is generally adopted when the extraction distance is less, when the number of hoppers are more and when project layout demands for two-stage conveying. Vacuum Extraction relies upon an air stream generated by partial vacuum drawn on the receiving station, by means of mechanical exhausters, material being dragged into the pipeline by vacuum created and moving in suspension. A bag filter unit with air lock unit, separates the material from the air at the receiving station for onward conveying to remote silos/for hydro sluicing. MBPL’s proprietary design Dome Valve has proven to be one of the best valves for the vacuum application also. MBPL’s Vacuum Extraction Systems are installed upto capacity of 74TPH and for power plants upto 600 MW.
