2. The blowing of steam through piping to remove debris from the pipe, cleaning steam lines to a steam turbine, cleaning plant expansion lines, or new installs. As the definition says, to steam blow a pipe requires steam to blow through the pipe. This pipe can be attached to a boiler or heat recover steam generator, and the other end of the pipe can be attached to a steam turbine.

3. Steam Blowing Procedure Before putting steam into the system, the control valves, turbine meters, instruments, vacuum ejectors and strainers etc. should be removed or blinded off. The steam headers should be slowly warmed up, one header at a time, while expansion of the line is observed. Condensate must be drained manually to prevent steam hammering. The headers should now be blown using a low pressure, high-velocity sweep as explained hereafter. Wherever allowed, only low pressure steam to be used if available at temperatures not exceeding 120°C.

4. Principle The principle behind blowing steam to clean the lines is that the thermal cycling (heating/cooling) and high velocity gas flowing through the line will "shock" the pipe to break the mill scale and weld slag away from the pipe wall. Ideally, steam blowing should be done prior to the system being insulated to maximum the thermal cycling of the equipment. If the system is insulated, a greater time between consecutive steam blowing operations may be necessary to allow the system to cool.

6. Purpose of steam blowing: • The purpose of blowing or cleaning the steam lines prior to starting up a new unit is to remove any foreign matter remaining in the equipment (i.e. superheater) and steam piping after installation is completed. • On older units the need for steam line blowing should be considered following major pressure parts repairs, where the possibility of introduction of foreign material into the system exists.
