If the tail gas of SRU contains more SO2 , is there any chance of smoke formation in stack after incinerator. If H2S slip smoke formation happens and increasing air ratio to control the stack some free. But sometimes in low throughput smoke is coming. is it because of more SOx and NOx...?

In the case of more SO2 in tail gas from the front end of a SRU, white smoke will appear in stack. Maintain proper air and acid gas ratio in the reaction furnace to avoid white smoke. Low throughput reaction furnace ratio should be maintained, otherwise you will always see problems in the incinerator stack.
