A set of computer programs and data tables of TTSE method to calculate the transport properties of water and steam has been developed. Its accuracy and computing speed were compared to those widely used in current industrial applications. The computing time was found to be half of the current method in the compressed-water and superheated-steam regions, and one-tenth in the supercritical region...

A superheater is a vital part of the steam generation process in the boiler-turbine system. Reliable control of temperature in the superheated steam temperature system is important to ensure high efficiency and high load-following capability in the operation of modern power plant. The PI and PID controllers are widely applied in cascade control of secondary superheated steam temperature process...

In this paper, an improved cascade control methodology for superheated processes is developed, in which the primary PID controller is implemented by neural networks trained by minimizing error entropy criterion. The entropy of the tracking error can be estimated recursively by utilizing receding horizon window technique. The measurable disturbances in superheated processes are input to the neur...
