GAS COOLING DENOX TANK CLEANING

NOx Control
Regulations for nitrogen oxides (NOx) emission are stringent and likely to become even more so in the future. Spray technology is widely used in waste incinerators, steel mills, cement kilns, power plants, pulp & paper recovery boilers and other manufacturing operations to control NOx. Dual-fluid atomization, where ammonia or urea is mixed with compressed air and injected into the gas stream, is the preferred approach in both Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) systems. However, there are many differences in dual-fluid systems and it is important to partner with a company that has a full range of services to ensure the desired system performance and emission reductions are achieved. Spraying Systems Co. is uniquely qualified to help you with your NOx control needs.

More than 80 years of spray technology experience has enabled us to develop the broadest product line of spray nozzles and lances in the industry. AutoJet Spray Controllers provide precise, close-loop control for our turnkey spray systems. Our industry-leading research and testing services allow us to evaluate your requirements and help ensure your performance goals are met.
