Methane - Oxygen gas burner Methane - Oxygen gas burner cruzerrain (Materials) (OP) 12 Mar 15 06:55 Dear All, Good Day Is there anyone has ever design nor use nor info the methane-oxygen portable gas burner ? its apply for the ladle preheat-er in steel industry. Sincerely yours and many thanks Kusuma RE: Methane - Oxygen gas burner Compositepro (Chemical) 12 Mar 15 21:15 What is your question? Methane is natural gas, which is a cheap and plentiful fuel. Oxygen is used in place of air to increase the flame temperature. Steel has a pour point higher than a methane air flame temperature. RE: Methane - Oxygen gas burner cruzerrain (Materials) (OP) 20 Mar 15 06:40 I mean, this burner is not used to melt the metal. It preheat the ladle to approx. 700-1000C.
