Buenos dias colegas, serian tan amables de indicarme si algunos de ustedes tiene informacion/experiencia de sopladores de hollin para calderas acuotubulares.


Gracias.

Hi Fran,

Sorry I do not speak spanish but I do have about 12 years experience with soot blowers. If you can email me at aubrey.green@ipaper.com maybe we can see what kind of problems you are having. I worked primarily with Diamond Power sootblowers.

Hi Aubrey, sorry i can't reply you the email, the problem in the sootblowers that exist is we accumulated a lot condensate in the pipes, our drainage setting is 504ºF, so when we start to blow always see condensate in the sootblower nozzle, when we measure the pipe thickness the thickness presents considerable wearing down around the sootblower, we don't have any trap on the feed line of steam sootblower.

Hi Fran,

I am sorry about taking so long to get back to you.

Are you saying the tubes where the sootblower blows is getting thin or is the nozzle getting thin?

If you are having tube erosion the best thing to do is evaluate your steam feed lines. Your steam should feed from below your lowest soot blower. All your lines should be inclined up to the poppet head on the blower. There should be a steam trap at the lowest point of your steam feeder. I know you said you do not have traps. If you are not going to install a strap you should at least install a valve at this lowest point and bleed the condensate out of the system after you warm up the steam lines but before you start blowing steam. Also, if the erosion is only on the first couple rows of tubes make sure your air relief valves are working. These valves keep condesate from accumulating in your lance tubes.

If you are having trouble with the nozzle getting thin in the weld area you need to check the welding procedure used to attach the nozzle to the lance tube. I have had welders not make complete penetration with their welds and the erosion in this area would cause the nozzle to crack off and blow into the boiler.

Ok, Thanks Aubrey, i'm going to check all those factors that you reffer. Thanks for your advices and i'll have you informed.
