Burning Liquid Fuels In CFB (Circulating Fluid Bed)
Burning Liquid Fuels In CFB (Circulating Fluid Bed)
(OP)
I am researching the suitability of burning liquid fuels in a CFB combustor. Our clinet has process waste from a coke plant that they would like to utilise for inceneration and power generation. This is char plant tar, liquor (97% water) and off-gas. Coal will be added at times to boost output.
Info from the 20th International Conference on CFB indicate that this (burning liquids in CFB's) has up to date only been done on lab and pilot scale, and the suitability for large scale projects are questionable and not proven....
Does anybody know if that have been done somewhere?
Regards

The liquor is basicly contaminated water that needs to be incinerated. But this have very little suplur so I guess it could be sprayed into the combustion chamber without getting in contact with the sorbent...
problem is the boiler contractor we are working with are not willing to quote on something they havn't done before
I think doing this might be possible but will probably require some sort of lab testing first...

It may be worth directly contacting a CFB supplier ( Metso, Alstom, FW Oy) to get their opinion- maybe the liquid fuel could be introduced in the fines recycle stream ( cyclone drains loop back to main combustor)?
