My coal boiler uses natural draft for recovering when temp goes down in water. Now if i make a longer neck on the draft tube, and install a small blower.. it would rekindle the bed of coal a tad faster. Now.. what should i use for blower, timer/ temp gain anticipator controller?! Hmmm this winters think tank project....... i sure do like burning coal for heating home. :woot: :geek:

Whatever you do, don't place yourself into a situation where the chimney can't draft fully and properly in a power failure.

I would put a "t" or 45* angle tube out side, and place blower on it that way, leaving the manual idle air door slot adjuster intact. Think i found style blower i could use, depending on what kind of temp drop/rise anticipator module i can find. maybe Johnson controls already has something that can just be plugged into side of other relays modules stack already on system.

Possibly the stage/sequencer modules that will work from Johnson Controls for auxillary draft blower.

Have a back up generator for power outages.. i burn a coal boiler i need backup power or have to put fire in boiler out within a resonable amount of time or go into major melt down.

FASCO makes small squirrel cage blowers. You need to control the draft on the blower's intake vent. A small, swiveling tab should do it secured with one screw. The fire must draft all the time whether the blower is running or not, power outage or not.The blower 's blades will accumulate dust and pet hair in the blade's cup. It will need to cleaned about twice a year.

Sounds like you are slowly trying to turn your hand-fed into a stoker. ;)

I completely agree with Rob.Before hacking and cutting up a fairly new boiler,consider a stoker unit,new or used it will last a lifetime.
This is what is installed on my boiler for forced cumbustion draft,fairly simple and parts are avalible,just need to hook up the blower/seloniod unit to the aquastat(i think?) some welding required.
Look at the clayton(USS) stoves,they have a blower hooked up in the ash pan door and have a shutter installed on the blower housing(much more simplier)

I am not sure the Harman engineers had that kind of firepower in mind...it would probably turn the boiler into a pretzel.

i am gathering up parts for a stoker. Got the burner pot, blower/screw drive, and screw flytes setup out of an EFM. Going to buy a rusted up 520 base, and use it as the pattern to build a new base. Then, when moneys not so tight buy a new boiler top from EFM. Will be a couple of years. Till then will keep the hand feed running and tweaking it for best efficency.

Oh I just put that pic in as an example; not trying to melt anyone's coal equipment. :angel:

I do have a nice little 12.5 lb/hr unit (thank-you again, scottscoaled, for thinking of me for that one) that would be just right for the 130k input rating on that Harman, though there might be some ash- and fines-removal issues with that ash door.
