Title Flame cutting under water reduces pollutant emission
Original title Autogenes Brennschneiden unter Wasser reduziert Schadstoffemissionen [in German]

Abstract Gas cutting units were modified for use under water. The cutting speed, quality, noise and pollutant emissions of underwater gas cutting were compared with conventional gas cutting units. Several types of sheet metal and metal plate (10-130mm in thickness) were used in the investigations. While the high quality of conventional gas cutting was maintained, the noise emission was reduced by 27% to 64dB(A). The dust emissions were reduced by factors ranging from 150 to 850. The emissions of ozone and nitrogen oxides were lowered to levels below the maximum allowable exposure limits of 0.1 and 5ppm.
