 are all down draft boilers - gasification

[mlappin]

The only updraft gasification boiler I know of, and I say this again, that I know of, was the one from Heatmor.

I’ve never personally seen one.

We have a festival over Labor Day in the county south of me that routinely draws 400,000-500,000 people a year. In 2015 the Heatmor dealer had nothing but conventional there. In 2016 when I took a G100 and set up he had nothing but conventional there. In 2017 when I took the Heatmaster show trailer and a G100s and ran the G100 in the trailer he didn’t even show up.

Crown Royal makes kind of a hybrid using 2 fans. There is the regular 150 CFM draft from underneath, pushing air up through the grates to burn the wood. Then there's also a smaller 60 CFM fan that feeds an injection tube at the top of the firebox blowing back down. This burns up the gases that are suspended in the firebox without sending them up the stack like a typical conventional

Depends what you mean by gasification, some would be complete controlled reburn (downdraft type), others like you mentioned will reburn a percentage of the gassses especially during the late part of the burn when the coal bed is exposed. Also there are a few updraft reburning units that use a catalyst.
The downdraft units (various brands) and a couple of catalytic models have passed EPA, an updraft with no catalyst hasn't yet that I'm aware of.

 thanks for all info - my stove is a Sequoforfyah big boss 2500 don't know much about it - just purchased it cheap- its a down draft has 6 pipes for exhaust coal my best to burn then - company went of busniess - cant find informantion  on it -thanks again

Post some pictures, maybe we can help.

[bill birks]

 having problems sending pics -maybe it me

Are you downsizing? I have no trouble since I started downsizing to 25%..

[E Yoder]

hmm.. I'd like to see inside the firebox, reburn area, exhaust tubes, etc. Hard to tell anything from the outside. And where do the lines hook up?

[bill birks]

 hope these willwork- tkanks

[E Yoder]

Is there a nozzle or slot in the floor of the firebox? Does the last picture show where a draft fan mounts up?

[bill birks]

 yes there is slots in fire box- yes the blower mounts in last picture -thanks for interest

[E Yoder]

So looks like you'll have make up some kind of fan/solenoid flap run by a temp control to control the draft. .. the details of how the airflow works is difficult without knowing a lot of detail of how it's constructed.
But in general if you understand the airflow you're 75%+ toward making it run well.

ok wants your opion of stove - plan on removing all covers and testing for leaks - guy I bought from said it 24 hours on fill up with 2 zones house and building -so if no leaks see how it goes with somenew parts-thanks again

[E Yoder]

I don't know much about that particular model so I hardly know what to think of it.. looks in need of some maintenance. . The former owner might be some help?
Some of the early downdraft models were kind of "unique" as a lot of manufacturers were in the learning stages. But I have no idea on that one. Have you checked in with Badger?
Definitely check for leaks first.
