I was posed with a question I could not begin to answer,

so I am appealing to the gods of Olympus. Think Ye,

before popping off. A coffee discussion got started over

cheap heating, On one side was my coal burning friend,

been in the industry for too many years, (like me and

wood). On the other was me the pellet/wood burner. In

the middle was a good listener and knowledgable heating

expert, (well not expert, but above average thinker).

It started innocently, what are you paying for pellets

these days. I said, about 150-180 per ton. The response

was, why don't you switch to coal. Bagged delivered Al

said he could get it for $150/ ton in three ton lots, or

switch to wood. We can get pinon/cedar for $125 per cord

if we pick up. The trailer can handle about six cords.My

rusty mind said that was a pretty good deal, but I

really wanted to run the cost comparison calculator.


Oil (2392.1)
Hardwood (814.15)
Softwood (1093.45)
Electric (2505.15)
Pellets (1430.7)
Natural Gas (1306.25)
LP Gas (2568.8)
Coal (732.45)
The above chart should give you some idea of the cost comparisons involved in using wood stoves, pellet stoves, coal stoves and the other popular home heating options. Note that there are often other advantages to using hearth products and renewable fuels - such as the fact that wood and pellets can be local resources. Hearth.com strives to educate our readers so that you can make an informed decision as to your home heating plans.



Turns out it's cheaper for coal. So, I said, I can get

good deals on pellets and you can get good deals on

coal, but they stoves are not compatible and can not be

made to work with different fuels.

Our natural third came in with a very good question, is

there a stove that will work with coal and pellets.

"No". Is there one that would work with wood and coal

and may be modified to burn pellets.

After my lecture about the way pellets are burned and

the techniques used to extract the heat through the

baffles and heat exchangers, Larry said... "Sounds like

a Riteway". Six or seven cups of coffee later and a lot

of doodling on napkins we came to a point we couldn't

answer all the questions.

Now the challenge for the Gods.... The Riteway burns

wood or coal and uses a "down draft" burn process,

(Larry described it as the roaring locomotive). Why

couldn't a burn feeder be used to do the same thing for

pellets and use the natural convection of the stove to

charge the fire,,,,,

I went duhhhh??? We talked about the Irish pellet

feeders and the ramp chip feeders used on commercial

furnaces and the outdoor wood burners (the riteway

already has thermostatic controls). And now I have spent

hours learning about a stove, lost to history that may

equal what we have now, but could be adapted.

I have taken off the Kevlar and the Nomex and am ready

for the old guard to wage war..... BRING IT ON
 
Before I bought my pellet stove I seriously considered pellets, but for venting reasons went with pellets.
Alaska stoves makes a model 140 auger feed furnace that can burn rice coal or pellets. Coal is by far
the highest btu output of solid burning fuels, and also the most economical.
 
We may be getting close. I work with Claude at Paromax (makes the Europa) from time to time trying to get his gasifier to burn rice coal. We got it to feed and get the tornado of blue flame, the issue was removing the ash fast enough. The ash extraction system was able to dispose of the ash ok, but the motor needs to run much faster. I have to get him re-interested in that. Imagine a true coal/corn/pellet stove that only required a swap of the burn pot. Imagine if the efficiency the Europa gets on pellets translated into coal. If anyone local ever wanted to see the Europa try to burn rice coal, let me know ahead of time and I can try to set something up.
 
LOL, I can just see the looks on peoples faces when they finally discover what it means to really get ash to clean up.
