Solid Fuel Boiler Heat Exchanger

First view of the super efficient heat exchanger test set up. In the video you will see the test run using a small amount of cardboard as fuel. It took 12 minutes from startup to boil 20 litres cold tap water in the second heat exchanger. Both units hold approximately 20litres of water.
The system is now being plumbed into a heating system and will be used to test the output through radiators and an indirect immersion cylinder. As the output of the stove cannot be controlled a seperate water circuit will be fitted to dump excess heat into underfloor hot water storage units which will basically consist of long rolls of plastic pipe coiled under the floors...

Also ,1400c is close to the melting point of stainless, your rig would be warped beyond recognition.You would need a foundry suit to go near it. Your dreaming. Like I said, you need a new thermometer

[waterboost]

you cant go within 3 metres of the stove when its running on full pulse...

As for steam and flu gases... your half right... The stove doesnt look like stainless any more... went through a lovely range of colours but now its mostly black... Will buy a new thermometer just for you ;)

Nice engineering, but I sugest you buy a new thermometer for checking flue temps. !400 c? Bullshit, it would be red at 700 and its nowhere near. As for the 20c after temp ,if theres steam coming out flue temp must be at least 100c. And if it was 20c ,it would not be light enough to rise up the chimney and start a thermal syphon. Get a fan like I did. If you think you have made a heat exchanger that extracts 1380c from the flue give Worcester Bosch a call, theyve been trying to do it for years.

Its almost see through when its on properly, not just red... steam does not come out of the flue... no thermal syphon which is a problem, need good ambient draw up flu. No mistakes here...

[waterboost]

No, it is not a gassifier. It is a waste engine oil stove but it will run on wood and coal. The two heat exchange boxes are just like you get in a steam train boiler... they are design to catch the heat that was wasted up the chimney.

...and I've already burned my fingers.

....and it takes that long for my kettle to boil 1 litre!

great stuff, very funny

[hanghoodiescum]

al have the teabags ready looks good

[wheelnutt]

I didnt say steam coming out of flue, read it again. If theres steam coming from HEAT EXCHANGER then the flue gases passing through must be at least equal in temp. And please show us the vid of the see through flue. If your flue is at 20c the fire will go out.

so is this a gasifier? nice results, I am very very careful with steam as steam burns are very nasty, but looks like very impressive results!
