This 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 workshop 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.
This course is intended for all senior boiler plant operators, repairers and installers, control system engineers, instrumentation engineers and technicians, boiler plant commissioning engineers, operation, maintenance, inspection and repair specialists, mechanical engineers and technicians, design engineers, consulting engineers.

The training methodology combines lectures, discussions, group exercises and illustrations. Participants will gain both theoretical and practical knowledge of the topics. The emphasis is on the practical application of the topics and as a result participant will go back to the workplace with both the ability and the confidence to apply the techniques learned to their duties.
