해양플랜트용 H-120 Class 파이어 댐퍼의 성능 실험

Abstract

In this paper, a fire resistance test was carried out in accordance with the change of the insulation conditions on the exposed side and unexposed side of a coaming to obtain the optimal insulation conditions for class H-120 insulation in connection with specimen1 of the preceding paper for an evaluation ofthe fireproof performance of fire dampers according to hydrocarbon fire conditions. Inthe test results, specimen2(88 mm, 171 ℃) met the class H-120 insulation conditions, but specimen3(76mm, 181℃) exceededthe thermal insulation acceptance criteria at 110 minutes. Therefore, specimen2(88 mm) represents the optimal insulation conditions as a possible lightweight materialas compared to specimen1. From a comparisonof the test results, we concluded thatthe temperature increase of the coaming insulation surface was influenced by conductive heat from the bulkhead and thatthe coaming surface was influenced by radiant heat fromthe blade and coaming.
