Steam Blowing Procedure - Boilersinfo

Steam Blowing procedure. This will blow out all the loose debris from the system. The two methods in practice for steam blowing are puffing method and continuous blowing. In the puffing method, a thermal shock is created, whereas in continuous blowing method, constant purge steam rate is maintained. In the puffing method, the pressure is allowed to decay during blowing.

An Introduction to Steam Boilers and Steam Raising - N.E.M

Mechanical Corrections. When a boiler must have optimum steam purity, operating pressure is a deciding factor in the design. At low pressures, the density of water is many times greater than that of steam. Therefore, adequate disengaging space and water surface area can be provided to achieve desired steam purity.
