PROJECT DESCRIPTION:
Staneco Corporation designed controls for multiple baghouse systems and hydrated lime injection systems used at multiple coal-fired power plants. The hydrated lime system had multi-point injection points and was used with fluid bed boilers. Hydrated lime is a proven alkaline reagent used to remove SO3 from the flue gas. Both pressurized and vacuum conveying was implemented. Blower motors, feeders, and rotary airlocks were controlled and monitored. Alarm conditions were monitored and control interlocks utilized allowing the system to operate safely.

PROJECT OUTCOME:
Systems provided an effective and cost-efficient way to reduce emissions from the fluid bed boilers. The use of control interlocks and alarm monitoring kept the systems operating safe and increased the equipment’s performance.
