Industrial Vacuum System for Fly Ash
Disposal at a Power Generation Plant
Engineered Industrial Vacuum for a Power Generation Plant

Power Generation Plant
Industrial Vacuum

A customer in the power generation industry commissioned DeMarco Industrial Vacuum Corp. to design and manufacture a system to dispense the fly ash runoff produced during power operations. The customer was already an owner of a DEMARCO® 2-cubic yard MAXceptor pre-separator, purchased for use with a rental vacuum truck. They were now seeking a cost effective custom solution to parallel the 27" HG 2800 CFM equipment they were renting. Our experts were up to the challenge, consulting with the customer to formalize project requirements and conducting thorough feasibility studies to evaluate site requirements and constraints to determine the optimal design strategy. Utilizing the existing equipment capabilities as a starting point, this retrofit would increase productivity and performance.

The retrofitted unit is able to accommodate material sizes from 0.2mm to 3" chunks, handling up to 10% moisture content, and vacuuming at a rate of up to 20 tons per hour. Vacuuming horizontal distance is up to 400', with a vertical capacity of up to 100'. The unit operates in temperature conditions up to 275°F. The vacuum is stationary, operating on 480 volts/3 phase/60 hertz power supply.

Overall dimensions include a 5' long x 5' wide x 19'-4 1/2" DEMARCO® MAXceptor pre-separator receiver, and drive package measuring 8'-5 3/4" long x 4'-6 1/2" wide x 6'-6" high. Accessories include 6" I.D. hose at 50' long, and 4" and 6" diameter pick up points. System vacuum points can be operated using one 6" hose or two 4" hoses simultaneously.
