DESCRIPTION
This workshop introduces the basic 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. 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.
