Steam Blowing - EnggCyclopedia

General procedure for cleaning by steam blowing Discontinue all firing and gradually open the temporary blowoff valve, to blow through the steam system and out the temporary blowoff piping. Caution should be exercised to always perform first steam blow at reduced pressure, in order to check out the temporary piping system, its supports, anchors and spacing between supports .

Applying ASME Boiler Code to Steam Generation Systems

(Page 1) The main focus of the ASME boiler code is on power boilers, rather than on petroleum refinery or petrochemical heaters, so definitions are sometimes not clear. Furthermore, it can be difficult to define which authority has jurisdiction over steam generation systems in the CPI. Even in the U.S. This article provides guidance on the requirements for stamping within the ASME code and

Steam and Condensate - A basic overview of a steam

As long as the amount of steam being produced in the boiler is as great as that leaving the boiler, the boiler will remain pressurised. The burner will operate to maintain the correct pressure. This also maintains the correct steam temperature, because the pressure and temperature of saturated steam
