Boiler Mud Drum Heating Coil Control Automatio

2019-10-17 · 1) A classic automatic temperature control valve that reads boiler drum temperature And adjusts steam flow. 2) Place a steam trap on the discharge line from the MDHC's. My idea here is that the steam will condense and flow if the Temperature inside is less than the saturation temperature. 3) Manual throttle valve to control steam flow.

Temperature Control via Affine Nonlinear Systems fo

2014-4-10 · For the operation of the supercritical once-through boiler generation units, the control of the temperature at intermediate point (IPT) is highly significant. IPT is the steam temperature at the outlet of the separator. Currently, PID control algorithms are widely adopted for the IPT control. However, PID cannot achieve the optimal performances as the units’ dynamic characteristic

Superheat Steam Temperature Contr

2010-8-3 · This is the method used predominantly to control steam temperatures. The basic theory of control by attemperation is that if a superheater is made large enough to give the desired steam temperature at low loads, it will give a steam temperature at high loads that is higher than that desired if there is no method of control.
