Abstract
A burner for liquid and/or gaseous fuels (A, B, C) for a premixing combustion system in graduated load operation of a combustion chamber includes at least one inner partial body (2) that extends in the flow direction; at least one outer partial body (4) which extends conically opposite to the inner partial body (2); and at least one other surrounding pipe (8). The inner and outer partial bodies form a central flow structure, whereby the two are supplied with the flow in effective connection with each other with combustion air (13, 14, 15). The main part of this combustion air (13) then flows through the two partial bodies through air inlet slits (11, 12) and forms one rotational flow in each of the adjoining flow chamber (5, 7).
