Combination Vacuum /
Pressure Systems
Utilizing the best attributes of vacuum and
pressure systems, the combination systems
offer higher conveying capacities over long
distances, while requiring reduced headroom
at the collection hoppers.
Pressure Systems
Pressure systems offer high-capacity fly ash
transport over long conveying distances.
Pressure vessels required at each collection
hopper are furnished with rugged valving with
hardened seats and discs, internal aeration to
provide positive ash flow, and air flow control
from the clean side of the vessel to provide
uniform, controlled ash flow to the conveying
line. Operating at pressures up to 35 PSIG,
pressure systems can satisfy conveying
capacities over 100 TPH.
Vacuum Systems
Vacuum systems offer a low-cost alternative
for low-capacity fly ash transport over short
conveying distances. Operating at vacuums
up to 20 inches HG, the system features
simplified controls, low headroom and a single
swing-disc type ash intake valve at each
collection hopper.
