화목보일러의 화재 위험성에 관한 연구

Abstract

In this study, we conduct fire experiment using model of sandwich panels and plywood to analyze the problem of existing wood boiler's fire accident. also, as a result of field research of wood boiler using household, we can confirm the high fire hazard and the preferred fire-fighting facilities are fire extinguisher and selfcontained type fire alarm device by the survey. based on them, we suggest these resolution for the safe use of wood boiler. As a result of three hours combustion experiment, the transmitted heat from chimney to sandwich panel wasn't progress to fire because of the sandwich panel's air bound. After 2 hours 3 minutes combustion experiment, the flame of plywood which contacted with chimney was head to fire. At this moment, the temperature of chimney was measured 350 degree celsius. The heat transmitted from chimney to plywood progress to the fire because it doesn't radiate the heat but accrued. Wood boiler’s connection of chimney and ceiling should be prevented fire from using incombustible material. Keep selfcontained type fire alarm device and fire extinguisher around the wood boiler. Wood boiler in current legal system didn't include to examination machine of the Energy Use Rationalization Act, not only refused the safety regulations for manufacturing step but also prevailed fraulent construction by unqualified person. Through revising related laws, we should provide users safety through revising related laws.
