Steam Blowing Silencers

Effective   in   the   removal   of   construction   debris, weld  slag, sand, oil, dust, rust  and  mill  scale from  critical systems  prior  to  plant  start-up.

We optimize our steam blows with quality engineering, and by utilizing the best equipment. Determining  pipe  sizing  and  design, pipe  routing, steam  conditions, noise  level, thermal  cycling, water  quenching, and  condensate  generation  are  all  factors  that – with   our  proper  planning – will  ensure  a  successful  steam  blow  operation.

WHY   PERFORM   STEAM   BLOWING  ?

When  pipe  is  fabricated  during  hot  working, a  heavy  oxide  layer  forms. This  layer  is  known  as mill  scale  and  must  be  removed  from  critical  systems  before  putting  them  into  service.

The steam blow method is similar to the exhaustive  air  blow  technique, but the boiler is fired to generate  the  pressurized  steam  used  to  clean  the  steam  path. Specialized  quick  opening  valves and a detailed procedure, along with the design of temporary spools, steam quenching devices, silencers, and  debris  containing  equipment  are  required  to  per

form  this  service.

Dry  Silencers  are  designed  to  vent  up  to  900  KPPH  of   steam  while  maintaining   a   85 dB   noise rating  or  less  at 50  ft. from  the  discharging steam. Other  benefits  include  eliminating  or  greatly reducing hot water discharge associated with traditional silencers, eliminating fall-out of moisture experience when quenching a traditional steam blow, and reduced equipment requirements and associated construction costs.

ANPAM  ENGINEERING can engineer and perform several different types of steam blow methods  depending  on  our  clients needs. System piping is modeled and analyzed for proper velocities, pressures, and disturbance factors. Modeling the system leads to verifiable results and compliance  with  all  client  and  specifications.

ANPAM  ENGINEERING  has  invested  a  tremendous  amount  of  time  and  capital  in  designing  our steam  blow  equipment  to  ensure  we  offer  the  most  effective  and  safest  equipment  available  to our  clients. A  strong  inventory  of  equipment  is  readily  available  worldwide  to  serve  both  small scale  and  large  scale  projects.
