摘要

現在家庭中都有許多的家用電器，而居住民眾家用住宅內部多為易燃裝潢材質，電器用品使用方法不當，一旦發生火災，常常造成重大人員傷亡及財物損失，因此電器火災的研究非常重要，以避免或減少類似災害之發生。
本研究是以基隆市中山區健民街32巷1弄38號半山腰的2樓加強磚造3樓加蓋民宅火災為研究對象，此次火災為典型煙囪效應的火災，並利用美國國家標準局建築消防實驗室研究發展之「FDS」軟體來分析民宅火場，以電腦數值模擬民宅火場各種物理現象，亦屬於場模式，適用於多重區間建築物且能模擬火災的環境，並針對上層溫度、氣層高度及CO濃度的變化，探討模擬參數對火災的影響，並可得知這些資訊讓我們重視此類火災。

Domestic electric appliances are very commonly used in modern families. Due to improper use of electric appliance and indoor combustible décor, once a fire happens, it will often cause great casualties and property loss. Therefore, the research of electric appliance fire seems very important, in order to avoid or reduce occurrence of the similar calamity.
This paper utilizes Fire Dynamics Simulator (FDS) field model simulation program to simulate a fire accident occurred in a hillside townhouse building in Keelung city. This is a typical fire of stack effect. Computational method has been used to study the upper temperature distribution, gas layer height and concentration of CO in fire site at the time happening. And the result offers the information to prevent the fire happen.
