EXPERIMENTAL AND COMPUTATIONAL PREDICTION OF CONCENTRATION OF CARBON MONOXIDE GAS RELEASED FROM EXHAUST TUBE OF GAS BOILER

가스보일러 배기통 이탈에 의한 CO가스 누출확산 실험 및 수치해석

In the last five years, 45 people died and 104 were wounded because of carbon monoxide poisoning accident. CO poisoning accident is higher than any other gas accident in the rate of deaths/incidents. Most of these CO poisoning accidents were caused by defective exhaust tube in the old gas boiler and multi-use facility. In this study, the spread of CO gas released from leakage hole of exhaust tube was analyzed by computational flow modeling and concentration measuring test. CO gas leaked form exhaust tube in a building was highest concentrated near the ceiling and formed the circular currents along the walls. Through these experiments and simulation, the reasonable installation location of CO alarm was made certain and suggested.
