The selective non-catalytic reduction technology (SNCR) is a method of reducing emissions of nitrogen oxides (NOx) by injecting the reagent directly above the combustion, where temperatures are between 850 and 1050°C. SNCR technology is widely used in cement, waste incinerators, biomass boilers or boilers with conventional fuels.
A NOxCare SNCR system is both cost efficient and high performing.
Key parameters to successfully operate a cost efficient SNCR technology are:
- The design and performance of injectors
- Optimisation and the programming of the controller
- The location of the injection points
- The temperature window at the injection point
- The choice of reagent
- Possible residence time
With SNCR systems installed at more than 200 facilities around the world, NOxCare has designed and optimised a high performing SNCR system for industrial sites.
At optimum process conditions, up to 80 % NOx can be removed with NOxCare SNCR technology.
NOxCare is a global leader in the manufacture and installation of SNCR systems
In October 2011, Yara acquired Petro Miljö, a leader of SNCR technology with over 200 systems installed worldwide. Yara renamed the company, keeping its expert team who have a deep knowledge of its customers processes and needs in different industry sectors eg: cement, incinerators, boilers, thermal, biomass boilers, glass, etc.
