Training Advanced controls of energy, steam and combustion processes

INTRODUCTION
With energy costs rising, steam production has become a major cost factor for the manufacturing industry. In order to improve profitability, plants have reduced the amount of vented or condensed steam and have reduced the number of boilers in operation. Although “closing” the steam system improves the energy efficiency of a plant it also increases the variability of steam quality leading to potential product quality or process operation issues. The Optimization and Controls of Furnaces, Boilers and Steam Plants course explains the different control strategies and process dynamics found in typical steam plants. This course also explains how to improve a steam system to be better integrated and responsive; a more robust and energy efficient solution.

OBJECTIVES
This 5-day course explains how to design a robust steam system that is both responsive to steam load demand as well as energy efficient.  The course begins with a review of thermodynamic principles and Lambda tuning procedures. The application of advanced control strategies to improve system stability is a primary focus. Topics include cross limiting, shrink-swell effects, plant master controller design and tuning, and cogeneration control challenges.
