FIELD: gas turbine plants.
SUBSTANCE: combustion chamber of gas turbine plant includes outer and inner housings, fire tubes having in their heads air swirlers and gas fuel sprayer secured to outer housing of combustion chamber coaxially relative to air swirlers. Air swirler is radial one. Outlet openings of gas fuel sprayer are also radial ones. Gas fuel spray nozzle is mounted in sprayer body at outer side of outer housing of combustion chamber. Relation of total surface area of outlet openings of gas sprayer to effective surface area of gas fuel spray nozzle of sprayer is in range 2 - 6.
EFFECT: enhanced operational reliability of combustion chamber due to prevention of increased circumferential non-uniformity of gas temperature field at outlet of it at damage of chamber.
