SYSTEM OF HEAT-SHIELDING SCREEN WITH ELEMENTS FOR INSERTION OF SCREWS AND METHOD TO INSTALL ELEMENT OF HEAT-SHIELDING SCREEN

摘要

FIELD: heating.SUBSTANCE: system of a heat-shielding screen with an element for a heat-shielding screen has large number of adjacent elements of the heat-shielding screen on the bearing structure. The element of the heat-shielding screen is fixed on the bearing structure with the help of at least one fastening screw in a device for screwing provided in the bearing structure. The screwing facility is equipped with a cone-shaped element for insertion of the screw, where the fastening screw may be installed or introduced. Also the object of the invention is an element for screw installation in the system of the heat-shielding screen, being the composite part of the heat-shielding screen system. Also the method is proposed for installation of the heat-shielding screen system described above, according to which the element of the heat-shielding screen at vertical movement relative to the bearing structure in process of installation is installed into its own position provided between adjacent elements of the heat-shielding screen. Further fastening screws are installed into the an appropriate cone-shaped element for insertion of the screw and are screwed into the facility for screwing provided in the bearing structure. Also the object of the invention is usage of the heat-shielding screen system for formation of a heat-shielding screen.EFFECT: invention makes it possible to simplify installation of a system of a heat-shielding screen on a combustion chamber wall.15 cl, 3 dwg
