I’m a Chevette expert, not a wood expert...can we even get jack pine here in southern Maine?  I’ve always been under the impression you weren’t supposed to burn pine in a woodstove or wood boiler due to the pitch making creosote or something similar.  What’s the deal on this? 

What’s the difference between Jack Pine and the big tall pine that grows in my yard?  I could stand to cut some of that down if I could burn it.  (I think it’s white pine.)

Is it the characteristics of jack pine or the way a gassifier works that makes it ok to burn it?

Last question...can you burn wood in a coal boiler?...for example in a keystoker?

Thanks - Bill

one of the very cool things about a gasifier is that it CAN burn softwoods as well as hardwoods without problems (assuming your wood is seasoned and that you run the thing properly (don’t let it idle a lot, which is where adding thermal storage comes in handy -burn it hot all the time, and store the heat to use as needed ) ). 

since the energy content of any wood is basically a function of the relative mass of the wood (virtually all wood has nearly the same heat value per pound) once you have a unit like a gasifier that can burn any of them, you can feed your gasifier ANY seasoned wood you can get most easily and affordably- with the only advantage of hardwood being that it’s more compact to store per amount of heat.  if you noodle around the web you can find tables listing both the relative BTU/cord and moisture levels of various wood species

Regarding coal-- one other thing to add into the mix-- a year and a half ago I was on a trip in PA and took my 10 year old son on a tour of an old coal mine in Lackawanna County.  The tour guide was a retired very experienced miner.  I was chatting with him afterwards and learned, to my surprise, that a very large portion of US coal is going to- get ready: China.  At first I was amazed, thinking that it was an awfully heavy/ bulky thing to ship so far.  then the retired miner pointed out to me that all the ships bringing manufactured goods from the Far East to the US might as well return loaded with something, and that they carry coal on their return trip.  Given the way that the run-up in energy prices is being driven in large measure by the energy appetite of the Far East, and given what that fellow told me (and he seemed knowledgeable and for-real, not one to throw information around), I wouldn’t want to assume that coal will be insulated from the run-up in fossil fuel prices

I’m officially overwhelmed with this project

In order to get things rolling around here, I decided to stick/go with wood today.  This decision was based on many factors but was partly due to the great feedback I got here, and the simple fact that I can almost heat my house now with the Garrison woodstove I have in the living room.  The way I saw it...if I can’t get anything done in the boiler department, I AT LEAST need to be ready to burn my Garrison full-time this winter! 

Based on this, I made a firm commitment to wood today by going out and buying a nice homemade splitter.  I then proceed to split that big ugly pile that’s been sitting in the yard for about three years!  I was pretty surprised it wasn’t in worse shape.  I bought a grapple about 4 years ago, bucked and split 3/4 of it with a borrowed splitter, and never got around to splitting the rest.  That’s why I went looking for a splitter...I don’t want to be in the position again of not doing it because I don’t have the equipment.  (I tried splitting it with a maul and it just wasn’t my kind of fun!)

I do still want to get into a wood boiler BUT am intimidated somewhat by all the choices, decisions, confusion, flue shortage, the high prices for the best...which is what I want but can’t afford, leadtimes, lack of knowledge etc, etc, etc.

Here’s a question that may not be answerable without more detail but I’ll ask it anyway.

If I install a non-gassifier, add on wood boiler (no storage) and use it faithfully, will it save me money over oil with prices the way they are now?  (I’ll buy log length wood, buck and split it myself...if I can find it!)

I ask this question because I’ve gotten some feedback outside of this forum saying ..."a boiler is just a woodstove if you don’t have storage”.  If that’s the case, what’s the use in hooking the boiler up to the FHW?  Am I just heating my basement or is one of these things going to heat my house via the FHW baseboard? 

Lastly...I’m wondering if there’s anyone out there who lives in Southern Maine / Seacoast NH who knows this stuff like I know a Chevette and would like to help a guy who wants to do it but can’t afford “expensive guidance” or “full-service” design and installation.  Figured I’d throw it out there.

Thanks again - Bill

“a boiler is just a woodstove if you don’t have storage”

Don’t let all this talk about heat storage scare you off. It definitely helps alot if you have a gasifier, but my father heats a 4500 square foot house in NJ with a 30 year old boiler, no heat storage, feeding hot water to two forced-air air handlers, gets 8 hour burn time, and with very little smoke. In the perfect world, gasification and heat storage would be ideal, but with the price of oil now, lots of set-ups will work, and save you a ton of money.
