Water Handbook -Boiler Deposits: Occurrence And Control | SUEZ

When calcium phosphate is formed in boiler water of sufficient alkalinity (pH 11.0-12.0), a particle with a relatively nonadherent surface charge is produced. This does not prevent the development of deposit accumulations over time, but the deposits can be controlled reasonably well by blowdown.

Screw Compressors: Types, Application Range And Control

Jan 01, 2008 · In principle, it is necessary to consider the volume-control options for dry-running and for oil-injection-type screw compressors separately. Controlling dry screw compressors Control by variable speed Because screw compressors displace the medium positively, the most advantageous volume control strategy is to vary the speed.
