| 摘要 |
The present invention relates to a process for partial combustion of cellulose spent liquors using a burner equipped with a liquor lance and an atomizing nozzle, which burner is connected to a reactor operating at pressures in the range of 1.1 to 150 bars while supplying an oxygen containing gas, whereby the weight ratio between the oxygen containing gas supplied through the burner and the spent liquor solids supplied through the burner is less than 2:1, and that at least half of the non-fuel bound oxygen required for the partial combustion is discharged into the reactor through the atomizing nozzle. |
