ABSTRACT:
A method of removing sulphur oxides from flue gases comprises atomizing a wet alkali slurry into a slurry spray. A pneumatically conveyed dry reactive recycled flyash is supplied in an annular pattern around the slurry spray to efficiently utilize the flyash without experiencing difficulties which were experienced in the prior art with regard to a wet mixture of the flyash.
