Model CBEX Firetube Boiler - Dryback

Cleaver-Brooks Firetube Steam Boilers

The firetube boiler is the flagship of Cleaver-Brooks. An integrated boiler, low NOx burner and Hawk Advanced control were designed and built with the latest innovations in technology for maximum efficiency and lowest emissions. Further reduce fuel usage with a stack economizer by recovering waste heat from the flue gases and using it to preheat boiler feedwater.

Model CBEX

Using advanced engineering methods, design engineers designed the CBEX to optimize every component of the boiler, including the burner, the furnace, and the tubes, in order to provide optimally balanced heat release zones and minimizing thermal stresses in the boiler. Extended heat transfer tubes only found in EX systems uses Computational Fluid Dynamics (CFD) calculations to optimize the geometry of the tube and increase heat transfer by 85%. The result of the advanced heat transfer design is higher efficiency in a smaller footprint. Offered in a two-pass, waterback or dryback design, the CBEX boiler package is engineered for long life, highest part load (or operational) fuel-to-steam/water efficiency, maximum safety and lowest emissions. Its quiet operation, ease of maintenance and flexibility to add desired options further enhances the package. Integration of the core components is the key to the CBEX systems. The superior Hawk control allows the boiler to run at the absolute maximum efficiency. Reduce fuel use with the optional stack economizer by recovering waste heat from flue gases and using it to preheat boiler feedwater. The LevelMaster low-water cutoff and pump control is the safest control available.
