FIELD: fuel combustion methods and devices.
SUBSTANCE: combustion chamber includes a housing, a flame tube located in the housing and having an inner surface limiting the cavity for receiving hot working gases from the combustion zone of the combustion chamber, and an external surface. Annular flow channel is formed between the housing and the flame tube. Combustion chamber also contains a segment holder, which is connected to the flame tube and in which the upper part of the flame tube is located. Between the segments holder and the flame tube a purging cavity is formed. Flame tube has multiple holes for striking jets for directing the flow of cooling air from the annular flow channel into the purging cavity.
EFFECT: invention is aimed at improvement of cooling efficiency of combustion chamber components.
