Theory:Sewage water from the boiler pressure and temperature are high, if discharged directly into the atmosphere, hot on the environment may cause pollution and noise, so the regular expansion of sewage reduced waste water down to slightly higher than the atmospheric pressure, temperature down to 100 degrees, expansion of the steam generated from the upper part of discharge, boiler water is ejected into the sewer. Parameters:(should be supplied by customers) 1\ pressure: design pressure : operation pressure: Max pressure:10Mpa(100bar) 2\temperature 3\media(ex: water,etc) 4\nozzle size
