This research is the first step of a complex research program that has the goal to retrofit the lignite burners of a 2×315 MWe units of a thermal power plant, in order to reduce NOx emission by staggered under-stoichiometric combustion. The straight-flow pulverized-coal burner will be built-on from a set of 16 modules. The experiments were made in a wind tunnel on a single module that was converted for the staggered combustion. The experimental data were compared to those resulted from the numerical modeling flow processes for the jets interaction, in order to achieve the desired aerodynamic.
