Luk,
Thanks for the answers
You said that no throttle need . Will throttle not improve the gas quality?

Andre,
No, it will not because everything in a DriZzleR happens in the flaming pyrolyse zone.

Re: Attempt to convert an IISc gasifier to drizzler
Hello guys.
There is something that i don't understand. In this test i've tried with clean water. But still, i dont get any blue flame. The flame color dont change. However, when i was exchange the water from past test i've noticed that water was without tar, only solid particulate in water surface. There is no black water anymore. Well, this indicate low quantity of tar generated, right?? But, why the flame color is not blue?
Investigating luk and pascal setup/tests i saw only few differences:
- My system has water scrubbers, they dont.
- They has condenser and i don't.
- Ambient temperature ( here > 30°C, germany < 20 °C )
Could this be the answer? The low quantity of tar produced is not condensing on my system?

Re: Attempt to convert an IISc gasifier to drizzler
the idea is to crack the tars not to scrub them out of the gas stream. Maybe you don't reach tar cracking temperatures of >850C.

Re: Attempt to convert an IISc gasifier to drizzler
I dont have the reactor temperature exactly. But i think is reached high temperature in the reactor. In this test (video youtube) my cyclone gets incandescent. I fed the reactor just like Luk and Pascal. My question is: there is no condensate on tar cracked? only water?
This video below shows at 6:20 Luk emptying his condenser. What is this? Only water? whats the red liquid?

Hi Andre,
i think the color of the liquid is playing games with the camera. normally the liquid looks like apple juice. It is not only water. There is also a contence of vinegar, coal dust, and a thing in german called "Holzgeist" known as methanol.

Pascal

Hi Pascal
So this methanol is from tar cracked? Are you seeing any reason why my flame is not blue?
Thanks!!

test a paper-filter or glass wool after youre water scrubber
the red color of the flame looks for me like coral dust is burning

Jan, thanks for the answer. I've tested with a fabric filter after water scrubber and not done, still the same.

Hi Andre
Hi Jan
If you than find no tar in the filter you have good tarless gas.
It is also possible that your flames goes red by waterdrops burning in the flame.

No the methanol is always there not only if the tar is cracked.So this methanol is from tar cracked? Are you seeing any reason why my flame is not blue?
Hi Jan
I also think the same. The flame color indicates not if you are producing tar. It´s only indicates how good your gas is filtered.test a paper-filter or glass wool after youre water scrubber
