Parts and auger tube air holes

Parts and auger tube air holes

PostBy: TweedFab On: Wed Feb 17, 2016 12:26 pm

I recently had the pot auger tube wear out on my 520 boiler. I used a piece of 2" sch 40 stainless pipe to replace the aluminum tube. The tube was damaged on the pot end in the process of removing it and I could not get dimensions of the air holes and did not notice the slots. Are the dimensions of the slots and holes published somewhere?

I am in need of some parts such as the worm bushing, and shear pins. The EFM dealer locator is woefully out of date (1 dealer I called said they haven't sold this product in 17 years...) Someone that can ship to me is fine..... My home is in Waynesboro, PA 17268.

Thanks,
Louis

Welcome to the forum Tweed,

I'm in southern York County and I get my EFM parts from Mark's Supply in Shenandoah PA. 570-462-0748;
http://www.markssupply.com/

Joe and the folks up there have been working on coal stoker boilers and selling parts for a very, very long time. Most of the time I get parts shipped, but once in a while I am up in that area and I get to stop in. A lot of neat stuff to see there, if you like coal stokers of course!

Also forum member Scrapper23_jr is an EFM dealer. You can send him a PM. Great guy to deal with to.

The feed pipe holes are 1/8" I believe. I'm not sure how far from the end of the pipe they are though.

Maybe an inch???

If you don't have an answer by tomorrow I can go out and find that piece in my scrap bin and measure it. I'll probably do it anyway now that I know I don't have that dimension written down.

I appreciate the reply with the dealership info and the air hole data. Could you measure the slot for me?
Thanks again,

Sorry Lewis, my only air tube is hooked to a stoker with fire in it. :D

1/4" should be close enough for the slot, it only has to clear the pin. You will know right away if it needs to be slightly bigger.

I make my slots 3/8"long by 1/4" wide. There are 7 - 1/4" holes with 1/8" separating them on the opposite side of the tube. They are drilled 1" from the end. Some people do different hole sizes or amounts. I have good luck with this way.

This forum is awesome. Thanks for the information. When I get my bushings and shear pins, I will shut it down and spend 30 minutes on the bridgeport fixing this air tube. 8-)

Is there a way to clean out airholes without removing the burner tube? I am getting the "stink" from my unit and have never had it before....??? Am I looking at the right thing first? :gee:

thanx, jeff

Nope.

Have you checked the flue pipe and draft?

Yeah, I checked the flu and I have a manometer hooked up and everything was good. I decided yesterday that I really didnt want to go anywhere so I pulled the thing apart. lots of fines had accumulated around the auger in the bottom of the hopper. when I hammered out the pot pipe lots of fines came out but by the time the holes appeared they were clean, so I brushed out the pipe, checked the pipe coupler for signs of a not right fit (tiny build up) and put everything back together. Stink was gone so Im assuming the holes were at least partially blocked. Did lose my fire, I guess because I had it shut off and the doors were all open... Back to normal operation and waiting for spring :)
