NEW GASIFICATION WOOD BOILER?

So . . .did you 'find' the video as your OP seems to imply? Or do you actually have inside knowlede of the fact that more videos are coming, as implied by your second post?

Tell us more. How are you measuring the 150,000 btu? What is the input and output rating? What kind of efficiency are you seeing? What kind of wood are you burning? What moisture content is the wood? Have you measured exhaust gas temps? How do you control primary and secondary air flow?

Interesting but how much $$$$$$$ and where is it made? Warranty? I'm not being critical I'm hopeful if it's made here. I bought an EKO 25 and have no experience with any other boiler and like my EKO. It bothered me though that the Checs could make it and haul it all the way to Wisconsin for 2k less than Econoburn or Woodgun could make it here.

We are estimating the btu's at about 170,000 via measuring the delta t. So we really close with our 150,000 btu. We havent really checked on efficiency yet thats what the labs are for. (OAK)We are using the required 4x4 test loads on burns ..and even with regular cord wood there is virtually the same effect. The 35 cord I mentioned is with OAK cord wood. The air is controlled by one fan and one flapper assembly to control the air..and as for stack temps we are looking at about 500 to 550 degrees

So what is the delta T? And where are you measuring it? What is the flow rate? Is this a downdraft unit?

Nice video but it didn,t show anything of value. What is it?????? Fire?

Yup, looks like a downdraft gassifier. If you don't kill yourself with the nifty chimney that terminates inside the building I think you will find a better response here being open and honest. You are not selling to ignorant buyers,you have a very informed audience here. Many would like to buy a good American made unit. With openess and honesty, you may even find some who would be willing to run a test unit for a season or two. Not many people will buy an expensive unit without a proven track record. I like the little glass window. I think the wire rack in the burn box is useless and takes up valuable wood space.

THE DELTA T IS THE MEASUREMNT (DIFFERENCE)BETWEEN THE HOT AND COLD SIDE ON THE STOVE MULTUPLYIN THAT BY THE FLOW RATE OF 7 GALLONS A MINUTE MULTIPLING IT BY SIXTY AND THEN MULTIPLYING THAT X 8.3 (WATER WEIGHT) AND THAT GIVES YOU THE ESTIAMTED BTU RATING..YES THIS IS A DOWN DRAFT UNIT..BUILT IN THE BEST STATE OF MINNESOTA....

I said "what is THE delta T" as in what are you seeing...

Very interesting design. I too would say that the rack inside the fire box is probably not necessary on the sides. That way you would be able to get more wood into the unit. Your gasification flame tunnel is an interesting design. It appears that you have a refractory piece with whole in the center that shoots the flame down onto a refractory block. Are you seeing any erosion over time on either? The design of the tunnel on down draft gassers is where several of the manufacturers seem to have not quite gotten it right...

i like that it is made in the US of A. just a few questions. is there one in central wi that i can see? when will the be ready for sale? how much will they cost? where can i buy one?

thank you kindly,
