Glad to see another 50. Was wondering if the "whitening" from ash on the back plates was common. Guess so.

Enerzone Bio 45. Very typical stove. Dump the pellets in and blow air thru the pot. The reason I like to sell them is Enerzone 5 star warranty. Other than that, pretty unremarkable.

looks just like the burn pot to my osburn hybrid 45

Osburn and Enerzone are both made by SBI.

Like the Drolet Eco-65 is the same stove as the Enerzone Euromax.
 
St Croix Prescott. More or less the same firebox bits as that Hastings posted by Franks except
I think the Prescott has a bigger ash pan and I've got the steel refractory panel
and that stove looks to have the older style faux firebrick.
Anyway here's a few pics of the inside. The burn pot just drops in the space
so it's easy to remove/reinstall for cleaning which I did today.

burn pot seated. You can see down into the ash pan in this pic. Stove came with
decorative grates that set on either side of the burn pot but when the stove is
in 24/7 use I don't bother with them because it makes it easier for the ash to drop
right down into the pan without them in the way.

oh cool. this answers my question of if the cab 50 and the ps50 are essentially the same stove w/ different hopper sizes.
at least the burnpots and baffles are, it seems.
i'm guessing pretty much everything else is the same too.

top feeder schmop feeder.
i love this burn pot.
when you see the vortices around each hole and the way it burns, you just know it's a good design.
my little blast furnace.
the holes never get plugged.
and the flexible auger seems basically impervious to jams.

Not at all. I'm a bottom feeder kind of guy.

The top feed systems feel badly engineered to me. It's almost as if because pellet stoves were originally designed that way, that some companies have a hard time thinking of a new way to approach the problem.

Specifically, the round shallow burn pot systems seem like a pretty poor approach - especially with the potential for ash to choke your flame.

I bet if you took an engineering team that has never designed a pellet stove and just gave them pellets and told them to design a system to get the most heat and efficiency out of the pellets, that little round burn pot wouldn't make it past the trash bin.

(Have a riled enough people yet?)
 
Yep, thats a good start.

I won't derail Dex's thread. :zip:

Its identical to the inside of the Hastings. You are right about the bigger ash pan, but thats not not really much of an issue for me. I would like it to hold more pellets. It barely fits one bag and thats if its completely empty and I move the pellets around with my hand to make them fit in the hopper. Otherwise I love it. Simple and easy to work on.

Man, I'm glad I've got a bottom feeding Harman.

Burn pots where ashcan surround your burn pot seems archaic? or not the best way to handle ash. And with an exposed igniter, seems like it would wear quicker as well. I wouldn't be surprised to see more pellet stove companies find alternative methods to feed pellets than a drop system.

Those round burn pots do not have an exposed igniter.

And that one that Franks posted can likely make most of the others look like they were back of the envelope engineering misguided brain eruptions.

Sounds like an interesting concept/approach, but it still has an "ash management" issue and I enjoy that my Harman mostly manages ash on it's own. But using the gases, etc, seems like an efficient way to boost combustion.
 
My bottom feeder has a bigger "ash management" issue then my top feeder does.

just sayin.
 
Hard to get any better pics. My 1st post (start of thread) shows most individual parts pretty well.

1 pics is the pot as is (dirty) another pic is the pot with the cast reburn plate out (temporary plate that burns pellets while Main pot is being cleaned/dumped)

Another pic shows the pusher out, cast reburn plate out and the "pellet speader" removed (to better show pieces.

Last pic is looking down burn pot. The back of the pot pushes ash out, the front of the pot is a "flapper" door. As the back gets pushed forward, 2 rods on the bottom sides of pot, push the door open.

All in all a pretty slick system. Only downfall to it... Is that the stove ramps up to Level 5 for about 30 minutes prior to.pushing out reburn plate. This is to get the "Clinker" (ash) hot to ease the removal (designed to burn corn also). After 20 minutes on High (5), the reburn plate comes out and pellets are ignited on the plate from the fire below. After about 5 minutes of pellets dropping and burning on plate, the pusher cycles back and forth twice to empty pot. The plate pulls back and the fire on the plate, drops into main pot. The stove then continues a High burn to build a "bed" of coals (although it doesn't keep it long) for about 10 minutes after clean cycle. So 30-40 min of Full on Blasting heat..

If your house is already at temp (stat satisfied) then its likely this pot change (what they call it) or cleaning will overheat the home and shoot way over the set-point. I get about 4°-7° during this cycle (depends on outside temp).

Ours looks pretty identicle to Xena's. St Croix must use the same pot and versa grate in all their stoves. we have the old style ceramic brick though and our drop hole is rectangle, no arch.

And all along I thought bottom feeders were poor design, trying to push pellets at speed and hope they burn.
Dropping pellets into a cauldron of fire made more sense to me.

Into the bowels of Hell? Well, since you put it like that, now it makes sense to me ;)

Here is the pot of the new stove by Paromax, called the Rafael. (all photos of pots after burning and prior to cleaning)

On this stove the fuel is dropped down to the bottom of this "tube" and baked on an ash bed. As the gasses come off the heated pellets, preheated air is injected thru the holes in the sides. I'll post a photo of it burning later as I want it running for the weekend. What you see at the bottom is three augers that are used for ash extraction. Maintaining the ash bed level is critical in the performance. Not too low or you can lose the bed, not too high or you may cover the bottom holes and lose some of the reburn.

As long as I dont change pellets, my settings are perfect. It will heat about 1500 SF of showroom at 2lbs per hour feed rate.

Hi Franks

Are all the components in that stove DC 12v?

Looks nice!
 
More pot for Dexter.

With and without wear plate installed.

Old skool pdvc.
