BOILER FLUE Russian patent published in 1995 - IPC

Abstract RU 2047043 C1

FIELD: thermal power engineering. SUBSTANCE: boiler flue formed by diaphragm panels 1-3 and attached to ceiling girders through hangers 10 has vertical rod 15 arranged between diaphragm panels that form flue ceiling, such as upper one rigidly fixed to ceiling girders and other one loosely joined for vertical displacement and provided with stop 17 attached, respectively, to flue ceiling. Mentioned rod 15 is fitted with bushing loosely mounted on it and is hinged through links to ceiling diaphragm panels of flue. EFFECT: provision for taking inertia forces during earthquakes, low displacement of ceiling relative to ceiling girders and, hence, reduced stress caused by this displacement at points of attachment of hangers to chambers and drum. 3 dwg
