DEVICE FOR PROTECTING SURFACES FROM HOT GASES OR PLASMA BY MEANS OF LIQUID AND ITS VAPOR Russian patent published in 1999 - IPC

FIELD: turbines, jet and rocket engines, MHD-generators where very hot gases or plasma come in contact with their tubes, nozzles, or blades. SUBSTANCE: device has structures carrying hot gas or plasma inside them or hot gas or plasma flows over them, and safety walls separating their surfaces from gas and plasma; liquid supplied to device under pressure between structures and safety walls penetrates through wall holes and is immediately converted into steam under the action of gas or plasma which prevents direct contact between gas or plasma and walls. Safety walls are assembled of plates or screens. EFFECT: improved reliability of gas or plasma guides, turbines, and blades. 8 cl, 9 dwg
