There is a possibility that an unexpected long time is required to identify the fire occurrence location in a room with obstruction of visibility by the smoke, distributed exhibit cases and production machines, such as in the factory where the floor space is extremely large and in the merchandize shops where various goods are exhibited. It is believed that identification of the fire occurrence location in the early stage of the fire makes the fire fighting more effective. For this purpose, a new algorithm for estimating the fire occurrence location and the heat release rate, is developed by transforming Alpert's equation, namely with the aid of the temperature decreasing property of the ceiling jet formed under the unconfined ceiling in a quasi-steady state. Compared with the experimental results, this proposed method is found sensitive to the number and installation interval of sensors used for the calculation and fluctuation of temperature data.
