ABSTRACT:
The present invention is directed to a process for efficient combustion of cellulose spent liquors using a burner connected to a reactor, while supplying an oxygen containing gas, which invention is characterized in that more than 80% of the oxygen which is required for the partial combustion of the spent liquor is supplied through the lance of the burner to the reactor as an oxygen containing gas at a stoichiometric ratio of between 0.3 and 0.6 relative to complete combustion of the spent liquor.
