This paper presents the results of experimental research on the modernization of technology for the removal of nitrogen oxides (NOx) from flue gas in hazardous waste incineration plant (waste-to-energy unit). The investigated technological solution is a combination of traditional SNCR (selective non-catalytic reduction) method, and a modern technology based on urea hydrolysis. A semi-operating hydrolysis reactor is applied to produce gaseous ammonia, which is subsequently used to remove NOx from the flue gas in a hazardous waste incineration plant. Both the NOx reduction efficiency and the operating parameters of the semi-operating device are observed. The results show that the proposed technological solution is very efficient in terms of NOx reduction, where concentrations around 60 mg/scm can be easily achieved. Due to the simplicity of the proposed solution, the semi-operating device is also very reliable. However, in case of insufficient heating of the transport paths of the generated ammonia, there is a risk of deposits and clogging, as presented in the paper.
