Abstract

The emission of greenhouse gases and other pollutants is a crucial parameter for an environment. In order to meet both the national and European requirements, it is necessary to constantly develop techniques of low-emission combustion. The results presented in this paper are to focus public opinion on primary methods for low-emission combustion, namely on new design of pulverized coal burners and their impact on lowering the NOx fraction in the exhaust gases when applied. Their aim is to shape a stream of air or air-coal mixture before combustion by changing the speed and direction of the streams. This could be done thanks to swirler design application into the current geometry, i.e. a row of stationary blades may be an efficient idea. This paper is a comparative study of the burner design with and without the swirler based on the results of CFD simulations. A complete description of the assumptions and the computational setup are also included.
