The amount of hydrated lime injected into the Dry Reactor can be adjusted to the acid concentration of the fluegases (particularly in the case of high pollutant waste) in order to maintain the flow of the scrubber drain in thesame order of magnitude as in the case of incineration of waste with an average pollutant composition givenin the HMB (nominal case). An automatic mode must be provided to adjust the amount of lime injected basedon the HCl concentration measured at the outlet of the baghouse filter.
