Modulating Water Level ​Control System

The Siemens Electronic Water Level Control System maintains a consistent water level, which is crucial for efficient, reliable boiler operation. The Siemens Modulating Water Level Control System offers more efficient boiler operation, with minimal boiler water carryover, and reduced thermal shock to boiler. For boilers with rapidly fluctuating steam loads, the Siemens system has the capability to include dual-element control, minimizing boiler drum swell and shrink effects.

VFD Feedback Sensor

Incorporated with a LMV5, a VFD control with actual motor RPM speed sensor provides reliable, efficient and safe control of the combustion air blower.

Further Information on VFD Feedback Sensor

Draft Control System

Draft control system to monitor the differential pressure between boiler outlet before the draft control damper and atmosphere. Based on a differential pressure preset set point, the system will operate the damper open for purge and based on a preset pressure set point and via a PID loop control the damper will be released to modulate to maintain the set point.
