HClear™ Programs: A Solution-­Based Approach to HCl Abatement

Fuel Tech recently developed HClear™, an HCl abatement program that relies on the injection of an aqueous solution into combustion gas stream to react with gaseous HCl. This technology involves an aqueous solution that is injected into the flue gas, downstream of the economizer outlet. Upon injection of the aqueous solution into the flue gas stream, a molecular precursor contained within the aqueous solution decomposes to form particles with submicron diameters, analogous to spray drying.
