Abstract
In a boiler plant for heat generation, which consists essentially of a combustion space and of a burner acting on the head side of the combustion space, this combustion space is divided into two parts (17,102a) by the insertion of an annular disk (103). A limited internal backflow zone (24) forms in the front part (17) in interaction with this disk (103). This disk (103) then causes external backflow zones (106) fed by recirculated flue gases (30) to form within the front part (17) of the combustion space, the flue gases of said external backflow zones being introduced into the combustion process of the burner, said backflow zones (24, 106) being in each case separated locally from one another. Better flame stabilization, lower pulsations and markedly lower pollutant emissions can thereby be achieved when the burner is operating.
