Therefore, good internal boiler water treatment programs are necessary. DEPOSITS. Common feedwater contaminants that can form boiler deposits include calcium, magnesium, iron, copper, aluminum, silica, and (to a lesser extent) silt and oil. Most deposits can be classified as one of two types ( Figure 12-1 )Get Price
Buildings that house steam boilers vary from huge electric utility plants to small refinery plants, or commercial businesses such as a bakery or a drycleaner.

The boiler-turbine unit control schemes have gone through several decades of evolution and, typ-ically, a cascade of PI/PID controllers based on single-input single-output control loops is designed in the plant to fulfill such tasks.6,7 The remain-der of this section will focus mainly on the con-ventional boiler-turbine coordinated control systemGet Price
Steam moving through a line at high speeds picks up condensate in the bottom of the pipes, much like wind blowing across a lake forms waves. When the high speed steam and condensate come to a bend, such as a 'Tee' or 90 Degree turn, the steam makes the transition, but the water slams into the side wall of the pipe.Get Price

Feb 25, 2004 · Boiler drum-level control is critical. Too low a level may expose boiler tubes, which overheats and damages them. Too high a level may interfere with separating moisture from steam, which reduces boiler efficiency and carries moisture into the process or turbine. The drum-level controller maintains the level at constant steam load.Get Price
On operating boilers, it is most prevalent near pre-boiler feedwater heaters and economizers.
