- Stoker Coal Boiler: eshland s130
I recently purchased a older model of the coal gun s130. It did not come with the hopper. I know its still available. Current manufacturer wants $400 for just the hopper. Question is, can i install a auger setup to feed directly into the boiler as is? Ive seen photos of some other boilers setup that way but haven't seen a coal gun direct feed. Is it possible or am i missing something that you need the hopper for it to operate properly.

It would probably cost you much more to start from scratch to build and install an auger feed system than it would to invest in a new hopper with the electric eye to control the coal level in the hopper to keep the coal level in the hopper very low and a small length fairfield grain auger with an intake frame guard to feed the hopper using the electric eye to control the coal level in the hopper to reduce the runaway fire risk as there is a physical break separating the fairfield auger from the AHS stoker hopper.
You would have to check with ahs to make sure the existing stoker wiring for the new hopper can be equipped with the heat sensor/snap switch and the electric eye to control an auger to prevent the stoker from running away with a hopper fire.
I suppose you could ask ahs about installing a new hopper on your unit as well as adding an indirect drive fan and the wiring for the electric eye to control a fairfield grain auger as well if you brought it to them to do.

You can run an Axeman type auger on it. But you would have to build everything but the auger and you would have to build controls for it. Not easy, but do-able.metallica21156 wrote: ↑Sat. Mar. 19, 2022 9:15 amQuestion is, can i install a auger setup to feed directly into the boiler as is?
Very early Eshand/AHS 130's had an Axeman type auger but it would be very difficult to find one these days and who knows if it will fit a newer boiler.
AHS currently offers an auger that is for filling the hopper. Nothing to directly feed the boiler.

If you're handy it's not that difficult to go with an auger.
Member *hotblast1357* has already done this auger addition to his Eshland 260 clone.
He may even have a hopper he may not need???
Personally I'd get it running off a crude hopper first before inventing some custom auger work.

This is a older eshand model. So it may work out better.

When I say early Eshlands I'm talking 1970's. The company has changed hands a few times since then and the designs have changed too. Anyway, it doesn't really matter because it would be nearly impossible to find the early Eshland auger and all the mechanical parts to make it work.
I've done a lot of thinking about how to make an Axeman auger work on an S130, just in case I ever find an S130.
These are the only pictures I have ever seen of the S130 with an auger. Good luck!

Thats the model I have and how it looks. Other then mine has the direct mounted fan motor. Wonder how they controlled the feed rate.

Feed Rate…As with ALL the AA, AHS and Eshland the feed rate is simply a function of the bottom ash being shaved off the fire column/tube bottom incrementally.metallica21156 wrote: ↑Tue.

All by Gravity feed be it from a hopper or the auger’s transfer head. This cycle is piloted by the Anthrastat control set point and what ash volume leaves allows equal volume of raw coal to move down at top of fire column.

Im sure it gets complicated the ratio of how much to feed based on usage.

It's not some ratio, they use a temperature probe near the grate.
This allows it to set the fire by depth by shaving off ash. The feed is just whatever ash is pulled out, fresh coal pours in to replace it on top of the fire.

My understanding was the ashing is temperature controlled by when to shake. So when it shakes it would feed as to replace the shaken ash or am i wrong?

Yes, the coal feeds when it ashes.

So auger would feed when ashing but you would need to know how much coal is dumping to replace dead ash. Thats the ratio im talking about.

You don't need to know anything about it. The feed rate is whatever can fall out of the feed tube into the firetube. The height of the fresh coal pretty much remains constant.

The auger is designed so that unused coal can fall back down the tube while it's rotating. The fire only takes coal as needed no matter how much the tube can deliver.
