The boiler components and their purpose. Standard 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 feed back 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 controlling what they are and how they are used. Flame detection methods are covered including the advantages of each method.
Systems for the safe start-up, monitoring, and shut-down of multiple burner boiler furnaces are covered in detail. Causes of furnace explosions and ways of avoiding them are discussed. The relationship of burner management systems and boiler control systems is explained. An understanding of boilers and boiler control is assumed.
