As shown, the atomizer comprises an atomizing cup 3 secured to a rotary shaft 4 and provided with a disc 7 having semicircular apertures 7a. The cup is surrounded by a housing having an inlet 12 for primary air and by a second housing having an inlet 11 for secondary air, and is fed with sulphuric acid waste through a fixed conduit 1. Exhaust gases, including sulphur dioxide, from the furnace are cooled in a steam generator, Fig. 2 (not shown), from which the steam passes to a superheater. Flue gases fron the superheater are used to preheat the secondary air flowing to the atomizer inlet 11.</p> |
