摘要

The invention relates to gas turbine engine combustion chambers, and may find application in the field of turbomachinery, in particular gas turbines ground. The technical problem solved by the utility model is to eliminate the possibility of flashback from the flame tube into the mixing channel of the second combustion zone of the flame tube. The problem is solved in that the two-band combustor comprises a housing, at least one flame tube with a first (duty) and the second (main) combustion zones arranged in series, the air passage formed between the housing and the flame tube, septum mounted in the air duct around the flame tube in the region of the second zone to form between it and a flame tube of the mixing channel. Vhodsmesitelnogo channel is formed between the flame tube and the upstream edge of the baffle. The second flow baffle edge adjacent to the flame tube, in the wall of which has openings for the mixing channel message with the cavity of the flame tube. Moreover the combustion chamber comprises a second fuel manifold of the combustion zone. The novelty of the proposed solution is that the fuel manifold is located around the second region of the mixing duct and communicates with it.
