Automation - Wikipedia

In open-loop control, the control action from the controller is independent of the "process output" (or "controlled process variable"). A good example of this is a central heating boiler controlled only by a timer, so that heat is applied for a constant time, regardless of the temperature of the building.

Water Handbook - Monitoring And Control Of Water Treatment

Sodium instrumentation has become very important as a means of determining steam purity. To determine the total dissolved solids concentration of the steam, the sodium level in a cooled steam sample is compared to the ratio of total solids to sodium in the boiler water. The most common technique used to measure sodium is the specific ion electrode.

The pressure within the boiler will vary as a function of the steam load, the type of burner control system and its mode of control. Example 6.5.2 Select and size the feedwater valve in Figure 6.5.6 In a simplified example (which assumes a constant boiler pressure and constant friction loss in the pipework), a boiler is rated to produce 10

OSHA Technical Manual (OTM) - Section IV: Chapter 2

Steam Distribution. The distribution system consists of valves, fittings, piping, and connections suitable for the pressure of the steam transported. Steam leaves the boilers at the highest pressure required by the process units or electrical generation. The steam pressure is then reduced in turbines that drive process pumps and compressors.
