Zusammenfassung:The present invention relates to an industrial furnace which mixes combustion air (A1) with fuel (F) to combust the fuel (F). In particular, the present invention comprises: first and second contact mixing type combustion devices which allow fuel (F1, F2) from a first fuel supply pipe (31) and a second fuel supply pipe (32) to come in contact and be mixed with combustion air (A1) supplied from a combustion air supply pipe (20) into a furnace (10) in order to combust the fuel (F1, F2); and a non-contact type combustion device which supplies fuel (F3) from a third fuel supply pipe (33) into the furnace (10) while preventing direct contact with the combustion air (A1) supplied from the combustion air supply pipe (20) into the furnace (10), before mixing the fuel (F3) with the combustion air (A1) contained in combustion exhaust gas (A2) for combustion. Therefore, highly efficient combustion can be stably performed. 연소용 공기(A1)와 연료(F)를 혼합해 연료(F)를 연소시키는 공업로에 있어서, 연소용 공기 공급관(20)으로부터 노(10) 내에 공급되는 연소용 공기(A1)에, 제1 연료 공급관(31), 제2 연료 공급관(32)으로부터 연료(F1, F2)를 접촉·혼합해 연료(F1, F2)를 연소시키는 제1, 제2 접촉 혼합식 연소 기구와, 연소용 공기 공급관(20)으로부터 노(10) 내에 공급된 연소용 공기(A1)와 직접 접촉하지 않도록 하여 노(10) 내에 제3 연료 공급관(33)으로부터 연료(F3)를 공급하고, 이 연료(F3)를 연소 배기 가스(A2) 중에 포함된 연소용 공기(A1)와 혼합해 연소시키는 비접촉식 연소 기구를 설치했다.
