Industry DeNOx

We design and manufacture Nitrogen Oxides (NOx) abatement and reduction systems up to 99%. Our experience makes us a reliable and competent partner in power production plants, coal/biomass boilers/furnaces gas turbines, diesel engines and static generators (diesel/methane/biomass), in several industry sectors (cement, steel and metals, chemistry) and in waste incineration.
Our support consists in the choice of the best technological solution based on the regulations and specific sustainability requirements of the industrial site. We also support you in the choice of reagents (urea solution, ammonia water or anhydrous ammonia produced in situ by urea termic decomposition) and monitoring systems.
All our DeNOx systems combine the maximum quality standards with high efficiency and low operating costs: we propose both catalytic systems with SCR technology, SNCR with the direct reagent injection into the combustion chamber and hybrid solutions that combine both technologies.


ECO-NOx™ SCR catalytic systems, with injection of urea (at 33% or 40%) or ammonia (at 25%), provide abatement performance up to 99% in the gas flow at preferably 300 -400°C. Plants are composed with modular reactors to adapt to any gas flow / performance requirement, and are suitable for retrofitting and new installations. Easy to install, ECO-NOx™ SCR catalytic systems require minimal maintenance and low investment costs and low reagent consumption but guaranteeing high efficiency. The nebulization occurs through Ecospray’s proprietary lances and nozzles into a static mixer or[...]


Our  Non-Catalytic ECO-NOx™ SNCR systems use the direct reagent injection (urea solution, ammonia water or anhydrous ammonia produced in situ by urea thermic decomposition) into the combustion chamber in order to reach efficiencies up to over 60% thanks to the use of proprietary design spray lances and a multi-level injection strategy. We provide systems suitable for small and large plants (1 MW ÷ 150 MW) pre-assembled and tested with low installation costs. For each specific plant, both for retrofit and new construction, we study spray nozzle geometries for optimal reagent[...]


The ECO-NOx™HYBRID systems combine both DeNOx technologies, catalytic and not catalytic. These systems are specifically designed to be adaptable to specific requests and to reach NOx removal efficiency up to 85% with operating temperature from 200 to 1000 °C.

These systems are the optimal solution in case of tight spaces that do not allow the installation of SCR systems and to limit the CAPEX.
