전로배가스처리장치의 후드내 가스폭발 방지방법Gas explosion prevention method in hood of converter flue gas treatment device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 배가스를 발생시키는 전로와 스커트 후드를 나타내는 개략도, 제2도는 연소공기율 변화에 의한 배가스량 및 조성변화를 나타내는 그래프, 제3도는 배연소가스의 가스폭발 범위를 나타내는 그래프.1 is a schematic diagram showing a converter and a skirt hood for generating flue gas, FIG. 2 is a graph showing flue gas amount and composition change due to a change in combustion air rate, and FIG. 3 is a graph showing a gas explosion range of flue gas.

Claims (1)

전로배가스처리장치에 있어서, 스커트와 후드사이의 가스포켓 부위에 침체되어 있는 CO가스를 불활성가스(N2)로써 취련개시전이나 취련개시후 약 2분간 퍼지(Perge)함을 특징으로 하는 전로배가스처리장치의 후드내 가스폭발 방지방법.In the converter exhaust gas treatment device, the exhaust gas treatment characterized in that the CO gas stagnated between the skirt and the hood is purged with inert gas (N 2 ) before or after the start of the blow or about 2 minutes after the start of the blow. How to prevent gas explosion in the hood of the device. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
