Re: Mikado first run

As for the location of the valve I had a very difficult time deciding if it should be up or downstream of the superheater, I chose downstream for simplicity of piping and I also thought it would be more efficient (steam would have more time in the superheater) and also not be susceptible to runaway ...

Re: Mikado first run

The valve I am using came from McMaster Carr, it actually is rated for 550 degrees, I looked at so many that I got all the specs mixed up. It was $188, the 750 degree valve was over $600 from a valve supplier, McMasters price was actually pretty good. I am happy with the new valve, hope it lasts a l...

Re: Mikado first run

My original throttle valve was a steam rated 90 degree ball valve, it said not to use it for throttling, and they were right. The problem is that there is only one end of the ball that has a seal on the 90degree valves, and the seal was Teflon so it began to flow and not let the throttle close. I fi...

Re: Mikado first run

Ok, the link is fixed. This was the first run and it was short. The ball valve I used for the throttle failed after about 500’. I replaced the valve and branch piping, made a change to the firing valve and have run it about two hours. This is my first attempt at oil firing, I wasn’t so sure after th...

Re: Re-facing Slide Valve & Ports

David,
Sorry to send you down the Rabit hole but that was “Lycurgus” must have been an auto type, or auto correct, mistake. I didn’t see it until now. Just check whatever you are using and it should specify for wet or dry steam, not sure but I think green velvet is only for wet steam.

Re: Re-facing Slide Valve & Ports

Something in your last post caught my attention, you said “superheater”, our scale super heaters normally don’t get hot enough, but it is possible that your steam oil is not holding to the the dry steam, you my check the specs on Lycurgus steam oil. Just a thought.

Re: welding boiler

There are acceptable procedures for MIG welding code boilers, I can’t remember all the specifics but it involves using flux core filler wire and shielding gas (double shield), it is not your everyday flux core wire it is a special wire specifically made for double shielding.

Re: Valve for Vacuum Brake

The small ball valves from American Model Egineering, work very well for what you are trying to do. Just leave the handle on them and build an extension with a yoke on the end that grabs the handle.
