When working with boilers, regardless what process control system is used or fuel being burned, you must control five basic functions: furnace draft, drum level, feed water, fuel air, and steam temperature. This course will teach you what must be controlled and how the control systems operate. The course introduces the practices of controls systems and safety controls for industrial steam generating boilers. It focuses on the control and safety requirements applicable to most types of boilers from small gas-fired units to large multi-fuel installations.
The course will provide training in how control and instrumentation is designed to manage the main variables such as drum water level, furnace draft, combustion fuel and air conditions. Burner management systems are introduced with their principal features including flame safety systems. The essential safety requirements for boilers and burners are identified and the corresponding safety interlocks are explained as practical solutions in accordance with the latest safety standards.
The course covers the boiler components and their purpose, SAMA and ISA symbols that are used in boiler control and identifying the engineering and control of boilers using the symbols and a method of presenting the engineering. The course includes defining the control and ratio control fundamentals feed forward control, feed forward plus feedback control, cascade control and ratio control and how they are implemented in boiler control. Also reviewed are control concepts proportional controls, proportional plus reset control, and proportional plus reset, plus derivative control what they are and how they are used. Flame detection methods are covered including the advantages of each method.
The course provides a comprehensive coverage of the modern high pressure boilers. It has been completely revised, reorganized and updated to include the latest techniques in boiler operation, instrumentation, control, troubleshooting, safety, emission and steam system management. The course utilizes actual case studies from around the world to highlight the topics discussed.
Following easy-to-implement guidelines and helpful time-saving diagrams, participants will go over strategies to methodically achieve the maximum utilization of fuel and energy to keep operating costs low and equipment performance high.
