Exhaust Cleaning Systems for stationary combustion engines, non-engine combustion processes and industrial boilers. Engine and non-engine combustion processes in stationary and industrial applications are subject to strict legal guidelines, just as 44. BImSchV (Regulation on medium combustion plants, gas turbines and combustion engines plants) and DIRECTIVE (EU) 2015/2193  (on the limitation of emissions of certain pollutants into the air from medium combustion plants), demanding the implementation of efficient measures to reduce emissions while maintaining the best possible levels of performance.

The ammonia (NH₃) necessary for selective catalytic reduction can be injected into the exhaust gas stream in a variety of ways. The most common way is the transformation and injection of urea solutions. Depending on the plant, ammonia can also be injected directly. The injection itself can also take place in different forms.
