Title Formation of nitrogen oxides in gas cutting and welding
Original title Stickoxidbildung bei Autogenverfahren [in German]
Bibliographic information Bundesanstalt fŘr Arbeitsschutz und Unfallforschung, Postfach 17 02 02, 4600 Dortmund 17, Federal Republic of Germany, 1980. 83p. Illus. 11 ref. Price: DM.15.50.
Abstract Report on systematic research to determine the quantity of nitrogen oxides produced according to fuel gas used (acetylene, propane, natural gas) and the burner of torch used (welding, cutting or heating). Production of nitrogen oxides depends above all on gas flow rate and distance between the burner and the workpiece (flame length). Required ventilation, and concentrations of nitrous gas determined in a welding shop.
