Suddenly Having Difficulty Maintaining a Fire in the S130

The boiler has fired, ashed out, and recovered. Sluggish though, needing about 30 minutes of fan cycle to recover. It ended up being almost exactly 24 hours between re-lighting it and its first ashing cycle.

Did the fire break the surface?

When the fan cut off I did not pull the tombstone cover off and look into the flapper port to check the fire. Guess I should have.

If you leave that cover off while adjusting, it makes life much easier. Am I assuming you are at room temp?

Isn't 110-120 going to make a small fire?

Larry,
I know you are starting your fire according to the AHS manual, but being a "Rebel" and building the new fire on top of old ashes/clinker changes this whole timetable.

Basically you would be restoring to an advanced fire from the get go, much like what existed before the grate cleaning, and not starting from scratch, and having to work through whatever variable might come.

It is good to clear the grates during the cleanings, I'm not advocating to leave old ash and not clean grate off.

What I do is hand pick some nice consisent sized clinkers through out the season and save a couple buckets full for later/next season start up...save no dust /power, just hand picked clinker.

Building a new fire on top of those clinker is a snap, air is easily passed through the spaces between clinkers and ash grate can be started much sooner, not to mention your fire is positioned high in burn pot right where you want it. :)

Gee, maybe the manual needs an addendum. :idea:

McGiever, I value your input here and I will know better next time as to how to re-start the AHS. This is only about the 4th time I've had to re-start it. I always followed the manual, and in the past used either Harmony or Blaschak to fire it up with no issues. I figure that Stockton is just a bit tougher to get going, but from here forward I will add some old ashes (clinkered preferably). The problem here is that I toss out ashes in the trash each week, and I didn't save any, so if the fire goes out again I'm still in the same boat.

I'm at work now, but when I left this morning the boiler was at 202 degrees and the ash grate was at 157 degrees, so it appears (for now at least) that I may have kept the fire for more than 24 hours this time around.

Somewhere in the bowels of the forum there is an LsFarm thread that details the effects of starting a fire directly on the grate. Needless to say, I would not start a fire in an AHS/Axeman without the firetube half full of ash after reading it! :shock:

This sure makes it appear as if AHS needs to update their operating manual. I hope I haven't destroyed anything by starting it on fresh coal.

No, you can't hurt that beast. The thread just details an unnecessary, aggravating adventure that could have been avoided with a pail of ash.

Fwiw. I start my 260s on fresh coal every year with no issues so far :) . Before I had ash augers I would just dump ash and un-burnt coal from first ashing cycle back into hopper for re-burn, now it all goes thru auger into ash pile. Maybe blow 25# un-burnt out auger. I think either way should work ok.

I've now made it to the 48 hour mark since my last re-firing effort and the fire is still there. Confidence is slowly returning. Sticking with the Stockton for now. It's the multi-match club right out of the starting blocks for me this season though. :oops:

Well, at least I can reminisce about three straight years of being a member of the single match club.

I'm at the 72 hour mark since third match, and the AHS Coal Gun has just fired, ashed, come up to temp., and turned itself back off again. Blue ladies are seen dancing through the flapper port. I believe the good times might be back! :D

The only oddities I noticed were:

1) An orange glow can be seen when the ash door is open (though no glowing ash is sitting in the ash tub).

2) The blue ladies are dancing atop black coal, with no orange glow seen through the flapper port.

3) Within only a few minutes post of the ash grate temperature probe hitting the 120 SV point and shutting down the ashing motor, the ash grate temperature flew up into the 200 degree plus range.

Does this mean my fire is too low? Should I drop my SV from 120 degrees to 110 degrees? Or just leave it alone for a few more days... ???

Leave it alone since you did use all coal to build the fire on top of. It is still expanding downward.

I would say that the fire size and fire position would still be changing for a while yet, especially in these temps we're having.

Having "blue ladies" is good, but watch in next couple days and see where fire is going to settle in at before considering any changes.

All this drama is very condensed when a new fire is built on top of ash. ;)
