Název v původním jazyce

Reduction of nitrogen oxides emissions in exhaust gases from waste

Popis výsledku v původním jazyce

The aim of the experiment was to verify the possibility of nitrogen oxides (NOx) reduction by iron compounds dosed into the flue gas stream under different combustion conditions. The motivation for conducting the experiment was to find cheap and available compounds that could streamline the process of existing denitrification methods in use. Such substances could be, for example, iron scale. The possibility of the catalytic ability of iron compounds in the reduction of nitrogen oxides under certain optimal combustion conditions is also confirmed by some foreign studies. Laboratory combustion tests were carried out on an experimental combustion plant, a periodically operating two-chamber furnace for waste incineration. The experiment was divided into two parts. In the first part, measurements of nitrogen oxide emissions were made when only natural gas was burned and gaseous ammonia (NH3) was simultaneously dosed with iron compounds. In the second part, measurements of the emission composition and the effect of the dosed iron additives on the amount of contained nitrogen oxides during the combustion of refuse derived fuel (RDF) with simultaneous combustion of natural gas in the supporting burner were carried out. The highest and comparable NOx conversion was achieved when two different additives, namely siderite and dried scale, were used under almost identical conditions in the refuse derived fuel combustion regime. The results of the present research confirm that the use of additives in the form of iron compounds can, with appropriate combustion process configuration, reduce the amount of NOx emissions produced, which can thus be crucial in meeting the increasingly stringent legislative requirements for reducing emission limits.
