Wide Range of Solutions for Precision Ammonia or Urea Injection
Waste, cement, glass, power, and steel plants plus OEMs around the world rely on us for NOx control solutions. Precision injection of the catalyst requires expertise in drop size, distribution, velocity, spray angle and spray direction as well as an extensive product line which we have. In fact, we have 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.
Typical Product Solutions
- Two-fluid and hydraulic spray nozzles: widely used gas atomizing nozzles include 1/4J Series nozzles, standard and anti-bearding FloMax nozzles and FMX FloMax® nozzles. FullJet® full cone and WhirlJet® hollow cone nozzles are typically used when hydraulic nozzles are required. All of our nozzles are available in a wide range of capacities, materials and connections
- Spray injectors: insulated or water-jacketed designs with an air purge for cooling are often used for NOx control. Customers typically specify injector length, material, coatings, flange type, single or multi-nozzle design and other features. We can meet nearly any code and design requirement
- AutoJet® NOx Control System: this system controls all components – nozzles, pumps, sensors and other hydraulic/pneumatic equipment – and makes automatic adjustments when operating conditions change. An automatic cleaning cycle can be included in urea-injection systems
- CFD modeling: validation of nozzle selection and injector placement in the gas stream using CFD is typically 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
