PROCESS AND PLANT FOR REDUCING NITROGEN MONOXIDE EMISSIONS WHEN BURNING SOLID FUELS

摘要

To achieve the maximum possible combustion, a hollow cylinder (2) is arranged in a heating unit at a distance from the burner and in the direction of the flow of exhaust gases. Said cylinder extends over the entire cross-section of the flow and comprises apertures (7). In particular, the hollow cylinder (2) is mounted in the region of the outlet of the flame tube (1) and at a distance thereto and/or the burner is adjusted in such a way that the hollow cylinder (2) glows on the edge near the outlet.
