Abstract

Efficient energy use becomes necessary since energy consumption has dramatically been increasing due to continuous economic development and population growth. In particular, high efficient vacuum glazing needs to be introduced to buildings where enormous energy loss occurs through windows and has been rarely used yet due to its high price and performance. Therefore, in this study, torch for glass welding was developed with CFD(Computational Fluid Dynamics) and experiments. Torch shape, nozzle diameter, nozzle arrangement etc. were mainly optimized and hydrogen-oxygen mixed gas fuels the torch. Finally, glass welding with the developed torch has been successful, showing that it can be used to develop economic vacuum glazing.

지속적인 경제 발전과 인구증가로 인하여 에너지 소비가 급증하게 되면서 에너지의 효율적인 사용이 필요하다. 특히 에너지 손실이 많은 건물의 창호에 단열성능이 좋은 고효율 진공유리 사용이 절실한데 아직 가격 및 성능등의 문제로 보급화가 이루어지지 않고 있다. 따라서, 본 연구에서는 저가의 진공유리 개발을 위한 유리 용접용 토치를 설계 및 제작하였다. 연료는 고밀도 열원인 수소-산소 혼합가스를 사용하였고 주로 토치 형상, 노즐 직경, 노즐 배치 등의 최적화를 수행하였다. 끝으로 개발된 토치를 이용하여 두 장의 유리용접을 성공적으로 수행함으로써 저가의 진공유리 개발 가능성을 확인하였다.
