Control Optimization and Tuning of Furnaces, Boilers and Steam Plants

By the end of this course, you will be able to:

• Apply effective PID tuning procedures to improve steam plant stability, responsiveness, and efficiency
• Analyze how steam system dynamics, thermodynamics, and plant design affect controllability
• Optimize boiler drum level, master pressure, combustion, and steam process control strategies
• Evaluate the role of deaerators, boiler feed pump systems, and ancillary equipment in overall control performance
• Identify opportunities to monitor boiler efficiency, reduce losses, and support more reliable plant operation

Description

Steam production is a major operating cost in many industrial and manufacturing environments, and small inefficiencies can have a significant impact on plant performance. As steam systems become more integrated and energy-conscious, tighter control can improve efficiency but may also introduce variability in pressure, steam quality, and process stability. Maintaining reliable operation requires more than basic control knowledge; it requires a practical understanding of how steam system design, load changes, equipment behaviour, and tuning decisions interact in real operating conditions. Optimizing steam plant efficiency significantly boosts overall system performance by reducing energy waste, cutting operating costs, and minimizing equipment wear.

This course provides a structured approach to improving steam plant control and boiler efficiency through applied control strategies, PID tuning methods, and system-level analysis. You will examine key steam plant components, steam flow and pressure dynamics, boiler ratings, heat transfer principles, combustion control, cross-limiting logic, oxygen trim, furnace draft control, boiler drum level tuning, master pressure control, and boiler efficiency monitoring.

Through practical examples and process-focused discussion, you will develop the knowledge needed to make steam control systems more stable, responsive, robust, and energy-efficient. The course is designed to help you troubleshoot common control challenges, improve tuning decisions, and support more efficient operation of boilers, furnaces, deaerators, boiler feed pump systems, and related steam plant equipment.
