Super Heated Wash Water System : The SHWW is generated by boiling point reduction principle, So that water remains in liquid stage even at temperatures above 100°C when left to atmosphere (in the centrifugal) through nozzles. A soft washing by water at 100°C and steam at +20°C (temperatures of SHWW kept at 120°C)
Welding torch. A welding torch head is used to weld metals. It can be identified by having only one or two pipes running to the nozzle, no oxygen-blast trigger, and two valve knobs at the bottom of the handle letting the operator adjust the oxygen and fuel flow respectively.
