FIELD: power industry.
SUBSTANCE: combustion chamber includes housing, flame tube with air supply holes to combustion and mixing zones, and front device with air swirlers and fuel feed atomisers. Flame tube of combustion chamber has geometrical and gas-dynamic criteria providing its optimum operating mode. Ratio of cross midlength section area to total effective surface area of all holes is 7.0 ±1.5. Relative carrying capacity of swirlers is 0.17 ±0.1. Air flow swirling intensity with swirlers of front device is 0.8±0.4, and flow velocity coefficient in flame tube holes is 0.22±0.1.
EFFECT: invention provides maximum economy, reliability and service life of engine.
