FIELD: power industry.
SUBSTANCE: burn-out protection of combustion products containment and cooling chamber section for solid propellant rocket engine charge liquidation comprises water distributing pipeline and spray nozzles. Disc spray nozzles generate large particle pulverised water flux in the form of circular screen and provide circular spraying of chamber section inner walls and combustion product partial cooling. Disc screen-generating spray nozzles are installed on water distributing pipeline inside of combustion products containment and cooling chamber section in amounts of 8 to 32 pieces per combustion products containment and cooling chamber section. Each disc screen-generating spray nozzle comprises 20 to 40 mm diametre inlet fitting, 3 to 4 external water distributing pipelines, 40 to 70 mm diametre circular deflector with slotted opening 5 to 20 mm wide with 45° expansion angle, and protective deflector.
EFFECT: effectivisation of combustion product containment and cooling chamber section inner walls cooling, keeping them from erosion and burn-out.
