Steamhead

is the boiler's waterline. If the feeder or pump controller has it too high, water will carry over into the steam lines. If you're not sure where the waterline should be, ask the manufacturer's rep.

Scotch-Marine boilers require very precise control of the waterline for proper steaming.

sorry to resort to cheap tricks, but I'm desperate. I presented a problem to you steamheads and no one even read it, can't anyone help a fellow heating comrade in arms.? I'm the one with the spitting air vents. You force me to appeal to your lowest instinct. I hope you can use your other head to help me with my problem. What should I look for? Working with a Scotch Marine Boiler and water shooting out the air vents 6 stories above . Thank you,waiting with baited breath

Well that got my attention. What type of one pipe system is it. If the boilers are dirty and its a scotch marine boiler there are "crows feet" or at least that is what i was told they were named. Theses allow access to the boiler shell around the big drum the burner fires into. I used a wand I made from copper pipe and a 90 as a sprayer to clean all the crap from inside. Next is just one tier of apts. affected or is the entire system. Maybe you have a slow or plugged return causing the condensate to back up. Also never forget some people will close the valve on the rad. when they get to hot and trap water. When they get cold and see the other rads. starting to work they crank it full open and whamoh steam meets that water thats just been freed and starts to hammer and spit. What pressure are you running @, more info please.

Boberg, you need to slow down and relax a little.

Your post has not even been up for 24 hours. The steam experts here do have jobs and personal lives, so give them a chance, we don't live here, just visit in our spare time. You also have unfortunatley picked a bad time to post as alot of the "Wallies" are on the road to Chicago to Wetstock II so they are unable to post right now.

Your original post will stay visible for 3 days. You can always add a post to your thread to "bump" it up to the top.

If you had to have an answer today, then I'm sorry the Wall couldn't be of help to you.

Have a good evening.

Just the facts Bob...!

I don't answer many steam call's because there are a lot of wallies more knowledgeable than I am. I've only been working around steam systems for 20 years. But, for starters, when you ask a question like the one that you want an answer to, you need to supply as detailed a background as possible. What Brand and size of Scotch Marine do you have. What was changed just before the spitting started? Is it a new boiler install? What type of system is it? One pipe steam has vents on each radiator, two pipe has them on main risers. Where exactly are the vents and what type are they. Is there a pumped condensate return system or is it gravity return? How old is the building?
You need to gather all the facts and make like Sherlock Holmes before sorting out a problem like you have. I didn't read your first post so if you gave all the above info already ...sorry.

Thanks for your reply. The problem is throughout the system, have to rely on what the super says, not been able to spend much time on the job. I don't think there is much water hammering going on ,will check steam traps and get back to you. Do you think it is possible that bad boiler water can cause the vents to shoot water up on the sixth floor?

boberg

Thank you Glenn for straighting me out , long time reader first time contributor. Hard to get all the facts when I have to address many different calls ,will have to slow down and play Sherlock Holmes. Just hoping for some direction which you have given me. Will get back to the wall with more info soon

take your time.

It took a long time for those old guys to figure out how to build them, it can take us a while to fix them.

I don't have the experience of most of the guys here. 15 years is nothing, but post those facts and you will get help when the young old guys get back.

David,

I'll try to keep Dan and Sheriff Murph busy tommorow at Wetstock II so maybe they won't see the post.

RESPECT

I've found this to be a very reputible site. I've discovered a wealth of knowledge from here by reading other people's posts. When I have used the PRIVILAGE to ask a question on this site, it's always been with much respect. This kind of sensationalism runs rampent throughout our modern media outlets. I'm saddened to see it has invaded here, no matter how "minor". It's no ones JOB here to answer you. Maybe the best thing for you to do would be to seek out and HIRE a qualified professional in your area if you're going to be so demanding for promt service.
