A presentation by Ken Heselton, a retired Licensed Professional Engineer with over 50 years of
experience in operating, maintaining, designing, construction, commissioning and troubleshooting of controls for boiler plants
and related systems.
This three day presentation explains the fundamentals of controls then leads the operator through control
technology from the time of the Romans to our present microprocessor based systems. The subject matter
is described using graphics of control elements and, when permitted, photographs of the trainee's plant.
Permission to visit the plant and take photographs of control elements is respectfully requested, alternatively
the purchaser can have an employee take the requested photos and provide them to KEH in JPEG format after
clearing them for this use.
Operators attending the class will be exposed to mathamatical applications and will be provided with a
calculator and instructed how to use it. A portion of the time may be spent in the plant using the features
of any distributed control or SCADA system that the operators would be using. The operators will also be
provided with a notebook containing material relative to the class and a useful appendix.
The class will cover:
- Process values including pressure, temperature, level, flow, and energy quantities.
- The relationship of flow and pressure drop.
- Other relationships between parameters.
- Concepts of control gain, integral, and derivative.
- Transmitter application to process values.
- Transmitter accuracy and it's affect on controls.
- Final control elements, control valves, actuators, variable speed drives.
- Simple loop construction and tuning.
- Feedforward and cascade control construction and tuning.
- Parallel positioning control.
- Inferential metering control.
- Full metering control.
This three day presentation can be performed at your venue for the sum of eighteen hundred
