The Two-Staged Reduction Selective Non-Catalytic Reduction Process of Nitrogen Oxides Inthermal Generation Unit Flue Gases

Abstract

The basic concern of research presented in the article was a development of selective non-catalytic reduction of nitrogen oxides in thermal generation units flue gases. The results of the experiments of two-staged selective non-catalytic reduction of nitrogen oxides with below-stoichiometric urea injection are described. Higher and more stable reducing efficiency with minimal formation of ammonia in treated gases is showed.
