Steam Turbine Gland Condenser Troubleshooting

12/22/2010 6:38 PM

We are facing steam blowing out from steam turbine end seals. When I checked the gland condenser its ejector is blowing a lot of steam from side charge. The machine is still in operation. What corrective action needs to be taken?

Your only option is to tear it down and replace the seals.

I don't think they sell steam turbine Stop Leak.

Gland condensers will eject steam typically, but the seals shouldn't... it sounds to me like your steam supply pressure to the glands is too high. That's the first thing I'd check. Next would be adequate flow and temperature of the cooling water to the gland condenser. It's a simple system, you either have too much steam to the seals, the gland fan (or ejector) isn't functioning (is it on?), or you don't have enough cooling to the condenser.

Go and engage a professional before you kill a lot of people trying to do it yourself....

Such safety questions cannot be properly addressed via a blog.......

This is a fairly common issue that most competent operators can deal with. I've seen it a handful of times. The usual cause was generally a stuck regulator, followed by an operator not turning on the fan/ejector. Based on the fact the guest hasn't responded, I imagine the problem was solved.

If he was "up to speed" on the problems, why would he ask here?

Having seen a couple of really minor/tiny steam accidents, I cannot imagine how bad a "big accident" might be.....

I alwqays say "better safe than sorry!"

From my experience and vantage point, it's a simple issue that would have been solved within 5 mins of finding it by 99% of operators I have worked with so your point about him being "up to speed" is well taken. All the gland seal systems I dealt with are 0.5psi steam so I guess I didn't see much of a safety concern, but I agree all steam needs a degree of respect.
