The invention is directed to a burner (1) of a turbomachine, particularly a gas turbine engine, comprising an upstream burner section (2) for providing a first fuel and/or an oxygen containing fluid to an upstream end of a burner interior (6), a downstream burner section (4) for providing a second fuel to a downstream end of the burner interior (6) or to a combustion chamber, and an intermediate burner section (3) between the upstream and the downstream burner section (4). The intermediate burner section (3) comprises an annular, preferably cylindrical, wall (10) surrounding a mid section of the burner interior (6). The annular wall (10), in turn, comprises an annular cooling fluid passage (11), particularly for guiding the oxygen containing fluid, and an annular fuel passage (12) for guiding the second fuel to the downstream burner section (4), the annular fuel passage (12) being more distant to the burner interior (6) than the annular cooling fluid passage (11). That means that two annular slots are incorporated into the annular wall (10). The invention is also directed to a method of operation and a method of operation of such a burner.
