Gas seperator/scrubber.

Gas seperator/scrubber.

Gas seperator/scrubber.

(OP)
We have a prototype high temp incinerator, the exhaust gas is urged along, at low pressure, by a vac pump which is way down stream in the cool area.
When the gas leaves the incinerator it is at quite a high temp, approx 600 deg C.  but as it cools down there is a tar like substance that settles out and completely gums up the pipework etc;
We are trying a simple home made wet cascade scrubber, but I'm sure this is not the best technique, would have thought the best place to deal with the problem is where the gas is quite hot.  I think we are trying to re-invent the wheel, is there a off the shelf solution.  Any ideas  PLEASE.

RE: Gas seperator/scrubber.

Hi Elvey. Try to inject the water with a bi-fluid spray in the throat of a ventury, at 600°C (this will evaporate the water, cooling the product, in a turbulent pattern), let evaporate the water by 1 sec (calculate the pipe lenght), before enter to separate in a scrubber.
I hope this work. Good look.
