NOx Control

Waste, cement, glass, power, and steel plants plus OEMs around the world rely on us for NOx control solutions. Spraying Systems Co. has the industry's largest selection of nozzles and the unique capabilities for injector design and fabrication plus automated systems designed just for NOx control and process modeling capabilities to validate performance while still in the design phase. Spraying Systems Co. provides total solutions and testing & modeling services allow for accurate and optimized results.

Precision injection of the catalyst requires testing to determine drop size, liquid distribution, velocity, and spray angle. Validation of the nozzle selection and injector placement in the gas stream using CFD modeling is typically also recommended. The model accounts for tower/duct/boiler structure, gas composition, temperature, velocity and flow to determine the effect on nozzle performance and identify possible problems such as wall wetting. This data is then used along with the chemical mixing efficiency to determine the expected reduction in NOx and ammonia or urea slip.
