I have a feeling I'm going to have to make these parts. So I have some questions.

Blower CFM?

Blower RPM, 1800 or 3600?

Do the bellcranks for the shaker have a ratio or they one to one?

I was really busy today replacing ballasts, bulbs and capacitors for my perimeter lighting. Thank god that's done. Its kinda deceiving but those lights are 20 feet in the air. I'm getting too old for this stuff.

Maybe tomorrow I can tear that hopper off and have a look inside

The cage of the blower gets bolted on the shaft of a standard 1725 RPM motor. That gets bolted onto the blower housing. That rubber coupler on the gearbox you have couples onto the ears in the blower cage. The gearbox gets bolted to the blower housing to.

The blower housing is the key here. If you can find that, you could make the linkage parts. Here's what it looks like.

If you can't find the blower housing and other parts you could contact member scrapper_23jr. He has loads of stoker parts.

I don't think removing the hopper will get you anywhere. I would look in the fire door to see if the grate plate and grates are in there.

I have some old 1725 rpm oil burner guns. If I remove the pump, and make a coupler for this Bond gearbox,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

I guess I need to check the stoichiometric ratio for Anthracite coal and make sure they make enough combustion air. Hopefully they make enough or maybe more. It's easy enough to throttle them.

So much easier to to buy the parts. It's just that no one has them. Mark's supply wanted me to tear the shaker assembly out and bring it to him and some F ing thing.

Not getting much info from the manufacturers or whoever. They all have the attitude that I should call "A Pro" LMAO. Like I would ever be happy with something "a pro" does. I've been less than impressed by what passes for "pros" today. If your selling heat and service I would think you should know stoichiometry and some basic thermodynamics.

I'm using electric for heating a couple of offices, and I had one of these "pros" tell me I should get "more efficient" electric heaters. I was like "dude they are all 100%". This "pro believed in over-unity I guess.

Well I couldn't find ya Joe. I was up in Nanticoke this morning to pick up a Van Wert, I thought I would swing by to see this monster you have there. Before I left this morning I wrote down the address that Google told me for Rancho Coal. When I found it, it was just a house. Oh well.

Don't disrepair, send Scrapper a PM, I'm sure he has that stuff somewhere. If not, I might just let go of one of mine.

So if I'm getting this right, the stoichiometric ratio for anthracite is 11.38 to 1?

And that the rule of thumb is to use 150% combustion air?

Am I on the right track?

I'm coming up with 222 cubic feet of combustion air for every pound of coal burned, figuring for 50% excess air

Engineering Tool box is showing excess air for Anthracite to be 40%

So the big question then is, how much coal does this thing burn expressed as weight/time

The bigger question is how much heat do you want in BTU's?

You know I swear that I saw that blower housing somewhere. It might be in a building down at South Tamaqua Coal Pockets

After chewing StokerDon's ear off last night, I figured it might be a good idea to post some pictures for scale.

Joe,

If it ends up that you have to make something.

You have the gearbox (speed reducer), that is the toughest thing to come up with. Next you need a blower to blow into that square hole. This guy has one, I talked to him the other day, it came out of a fairly big stoker boiler.
**Broken Link(S) Removed**

Next you need to mount the blower and gearbox to the back of the furnace.

You can use flat stock, some rods, some clevis pins and a couple pillow blocks for the linkage from the gearbox to the grate plate in the stoker.

Then come up with a way to couple a 1725 RPM motor to the input shaft of the gearbox.

Should be easy, it will just take a bit of time.

I just heard you might be getting a visitor tomorrow. Hopefully he is bearing gifts!

-Don

Visitors visitors visitors, all the players in the coal business are gravitating to my door. I swear George's ghost is here. I think I need one of those commercial coffee pots.

I got to tell you this buying the shop of a mining company, is like some kinda weird Deja Vu all over again. I came here chasing gas, but when I found this place, I loved it even though I'm on the Coal side of the Lackawanna Syncline.

Funny thing, my mother carried me to term while working in the office of The Badenhausen Boiler Div of Riley Stoker.

Was that some kind of omen or something.

View from my back upstairs office into the welding shop. Lots and lots of bucket and track repairs went on there.
