BURNER RETROFIT & CONTROLS UPGRADE

SUB 5 PPM NOx

NEW CLEAVER-BROOKS SBR-5 ULTRA LOW NOx BURNER

5PPM-NOx-BurnerULTRA LOW-NOx EMISSIONS – sub 5 ppm
3-4% O2 – across a wide load range
DUAL FUEL – natural gas & no. 2 oil; fuel switchover without mechanical adjustments
MAXIMUM EFFICIENCY – provided by standardized parallel positioning
OPERATIONAL RANGE – 6:1 turndown when firing natural gas
UNIFORM FLAME – for equal heat transfer allowed by premix fuel
EASY ACCESS – air housing for internal components
INTEGRATED CONTROLS – with remote IoT monitoring capabilities
SUPPORT – locally trained reps & certified technicians
SILENT OPERATION – with an advanced combustion air fan wheel; less horsepower and less noise
ULTRA LOW-NOx/CO – achieved without a fragile surface combustion burner head, making it more safe
 

SELECTIVE CATALYTIC REDUCTION

SUB 5 PPM NOx • SUB 5 PPM NH3 SLIP

SCR is a post-flue gas treatment that is capable of reducing NOx emissions from a wide variety of boiler systems. SCR uses ammonia as a reducing agent, which is introduced into the flue gas stream. The mixture then comes into contact with a catalyst, selectively transforming the NOx into harmless nitrogen and water. Options are available for reducing CO emissions as well and can be integrated into a single packaged solution.
