The combustion chamber is characterized by an annular-cylindrical space, which consists of two reaction chambers (8), arranged at the end, and a collision chamber (12) placed therebetween. The reaction chambers (8) are fitted at their face-sided ends with a number of burner elements (A, B), arranged axially parallel, their number depending on the output of the combustion chamber, which burner elements are in each case mirror-symmetrical to each other in relation to the central axis of the collision chamber (12). From the collision chamber (12), an annular mixing chamber (15) goes off to the turbine inlet (17). Each burner element (A, B) is provided with a twist member (6, 11), which in each case is orientated in opposed sense of rotation compared with the mirror-symmetrically arranged twist member.

An annular burner assembly for a gas turbine comprising: an annular collision chamber; a first annular reaction chamber communicating with a first side of the collision chamber; a second annular reaction chamber communicating with a second and opposite side of the collision chamber; a first annular array of means for directing a plurality of swirled mixtures of fuel and air into the first reaction chamber; a second annular array of means for directing a plurality of swirled mixtures of fuel and air into the second reaction chamber; said directing means having a fuel nozzle, a premixing tube, and a swirl body; said first array being in a first plane and said second array being in a second plane that is parallel to said first plane; each of said directing means in the first array including means for imparting a swirl in a first direction to said mixtures emitted from the first array, and each of said directing means in the second array including means for imparting a swirl to said mixtures emitted from the second array, such that each swirled mixture emitted from the first array encounters in the collision chamber a swirled mixture emitted from the second array, said swirled mixture from the first array traveling in a substantially opposite direction and swirling in an opposite state from the swirled mixture from the second array of directing means.
