HEAT SHIELD WITH CARRYING STRUCTURE AND METHOD OF CARRYING STRUCTURE COOLING Russian patent published in 2017 - IPC F23R3/60 F23M5/08 

FIELD: heating.

SUBSTANCE: each bar of the heat shield has a cold side facing the carrying structure and a hot side opposite the cold side and loaded with a hot medium. Each bar holder has at least one holding portion for fastening to the bar of the heat shield and one mounting portion, with the possibility of being attached to the carrying structure. The mounting portion can be fixed to the mounting slot running in the carrying structure. At least one cold air channel is provided for protection against hot gases. In addition to the mounting slots, at least one air cold slot is provided on the carrying structure. The cold air slot is partially blocked, at least, for the heat shield bars, fixed on the carrying structure, in the longitudinal direction of the cold air slot, so that it forms a slot portion in the shape of a channel, which at least one cold air duct enters. The cold air, flowing out of the cold air channel, can rotate substantially in the longitudinal direction of the cold air slot.

EFFECT: heat shield provides cooling of the carrying structure and prevents its scaling due to suction of the hot gas.
