It is the first time that a phase compensation for real roots, i.e., the twin lead/lag loop which is facile for engineering applications, is used in superheated steam temperature control.
Moreover, a formula to calculate the setting parameters is presented, together with a practical example of its engineering application in superheated steam temperature control with single-stage attemperation in a power plant boiler.
Because the control performance is remarkably raised, the set values of the steam temperature control system can be raised above rated values and also the operational economy, without impairing the operation safety.
The sample temperature is controlled by a fast-acting temperature control system in a range of 6-300 K to an accuracy of 0.3-0.05 K.
A temperature control system with a device for the dynamic switching-on of the heating elements of the growth furnace is described.
