Customer:
Loma Linda University
Application:
Loma Linda University’s main campus hospitals require hot water for use throughout the building and steam for sanitation, humidification and clean steam production.
Key Challenges:
As part of the Loma Linda University Campus Transformation project, two new hospital towers were added. The additional facilities required additional steam, which was provided by higher-capacity boilers. R.F. MacDonald Co. was selected for this project by providing total integration services, including:
- Engineering and installation support
- Supplying the boilers with our newly patented Direct Urea Injection with SCR technology to meet emissions regulations
- Complete startup and testing services
Solution:
R.F. MacDonald Co. supplied three Cleaver-Brooks CBEX Elite 1,400 horsepower firetube steam boilers. Each boiler can produce up to 48,300 pounds of saturated steam per hour. Our newly patented Direct Urea Injection with Selective Catalytic Reduction technology was installed. At approximately 58 MMBtu/ hr, the larger boilers are required to meet sub-5 PPM Low NOx regulations set by the South Coast Air Quality Management District.
Results:
Cleaver-Brooks Profi re XL Burner with Direct Urea Injection SCR
