SSM prepared construction documents for the installation of a dual fuel 1,200 HP boiler to replace a 67 year old water tube boiler. The new boiler will provide a better energy efficiency and turndown ratio for off-peak conditions. The project included replacement of two 75,000 lb/hr deaerators with custom deaerators that could be modified to fit the available space.

SSM utilized high definition laser scanning to document existing conditions in the 3 level boiler building. SSM mechanical engineers prepared a detailed flow diagram of existing piping and instrumentation.

The structural scope included design of a boiler access platform, roof modifications for the new stack, and structural support of the economizer located on the third floor. The existing steel was detailed using 3D laser scanning and field measurements to identify scope of removal and replacement of deaerators located on the third floor.

The electrical design included power, instrumentation, and controls. SSM electrical engineers provided a short circuit analysis and breaker coordination study for replacement power systems. The instrumentation and controls was designed to integrate with owners legacy building management system while maintaining owners preferred boiler combustion controls, boiler water level controller, valves, and sensors.
