Combustion method for atmospheric firings and device for carrying out the method

摘要

The object of the invention is to provide a combustion method for atmospheric firings and a device for carrying out the method, which substantially reduce the emission of nitrogen oxide and lengthen the useful life of the burner and of the flame tube. This is achieved according to the invention when a portion of the (thermal) radiation (8) produced during combustion is dissipated to the outside without striking the flame tube (5), and a portion of the already cooled flue gases (11) is reintroduced from the outside into the flame tube (5). For this purpose, a plurality of recesses (cutouts) (6) are arranged in the flame tube (5). <IMAGE>
