Abstract

In this study, fire cases were analyzed for tar and wood vinegar, which are combustion products of wood, and the possibility of fire was confirmed by conducting a reproduction experiment. In particular, the focus was placed on the possibility that the flame of tar generated inside the flue of a firewood boiler could fly away. For the preparation of tar and wood vinegar for the combustion experiment, tar and wood vinegar were collected and used in the experiment while burning oak wood in a charcoal kiln with a height of 0.5 meters. As a result of observing the combustion phenomenon, the temperature outside the flue increased to a maximum of 655℃ 10 minutes after the start of combustion. and As high-temperature heat was supplied, the movement of the fire was confirmed as the heat flow and pressure were radiated inside the flue.

본 연구는 목재 연소생성물인 타르 및 목초액을 대상으로 화재사례를 분석하고 재현실험을 실시하여 화재발생 가능성을 확인하였다. 특히 화목보일러 연통 내부에서 발생되는 타르의 비산에 의한 비화 가능성에 주안점을 두었다. 연소실험을 위한 목재 타르 및 목초액의 준비는 참나무를 0.5미터 높이의 숯가마에 연소시키며 타르 및 목초액 채취하여 재현실험에 사용하였다. 연통내부에 신문(종이)을 소각하면서 소화 후 연소현상을 관찰한 결과 10min 시간경과 후에는 연통내부에서 강력한 화염이 분출됨을 확인할 수 있었다. 연소시작 10min 후 연통 외부의 온도는 최고 655℃까지 상승되었고 고온의 열기가 공급되면서 연통 내부는 열기류와 압력이 발산되면서 불티의 이동이 확인되었다.
