ARCTIC VERSION GAS TURBINE PLANT HEAT AND SOUND INSULATION CASING Russian patent published in 2018 - IPC F02C7/24 F01D25/00 F16M1/00 E06B5/00 

FIELD: motors and pumps.

SUBSTANCE: arctic version gas turbine plant heat and sound insulation casing is designed for the gas pumping units and power plants gas turbine plants thermal insulation and noise protection. Casing contains the gas turbine installation frame, roof and walls with doors, rigidly connected to the gas turbine plant roof and frame. Roof and walls are made three-layered and contain external solid steel sheets, internal perforated steel sheets, between which the non-combustible heat and sound insulating material is laid. Walls and roof are made load-bearing with the closed cross-section load-bearing elements, to which external and internal steel sheets are welded in. Doors contain: outer casing and inner perforated box-type casing made of steel sheet, with heat-insulating non-combustible material between them and U-shaped supports. Casing doors are provided with sealing elastic gasket and are locked by means of rod lock, equipped with the “Anti-panic” type internal opening device. Between the gas turbine plant frame and the casing walls, a sealing elastic gasket is laid. At that, the door is additionally provided with made of fire-resistant material second elastic sealing sealant, along the perimeter the door frame contains steel shape, which internal cavities are filled with the non-combustible heat-sound insulating material, sealed with the elastic sealing gasket and made of fireproof material elastic sealant sealing. Door is made with the light aperture, in which the triplex two-chamber insulating glass is hermetically secured, on both sides sealed with the elastic sealing profile. Frame, walls and roof load-bearing elements internal cavity bottom and outer walls are insulated with the non-combustible heat-sound insulating material. Casing frame is provided with at least one built-in electric heater. Casing walls and roof, non-combustible heat-sound insulating material in the walls and roof thickness is from 100 to 150 mm. Casing is provided with the protective insulated cabinet for the gas turbine plant parameters measuring instruments cabinet placement, mounted outside the casing and containing metal welded casing with the outer and the inner housings, between which the non-combustible heat-insulating material is laid, electric heater with thermostat and door / doors, sealed / sealed with the frost resistant rubber, as well as hermetic cable / pipe glands. All welded seams in the casing are made continuous. All aisles in the casing are made sealed.

EFFECT: improved performance due to the operating conditions expansion, including for the outdoors operation at the ambient air extremely low temperatures, while maintaining the high strength of the structure.
