intimate contact with the flue gas to optimize absorption efficiency and drying in the spray chamber. For large utility boiler applications (illus-trated here), flue gas enters the spray dry absorber at two locations: the roof gas disperser and the central gas disperser. Smaller, lower gas flow installations require only a roof gas disperser.

Wet Flue Gas Desulfurization Ammonia Gas Scrubber Wet Ammonia Scrubber For Boiler Flue Gas Desulfurization Manufacturer US $1500-$7000 / Set 1.0 Sets (Min. Order)
risen price of limestone, the current desulfurization system power price policy of China cannot compensate the running cost of the desulfurization system in power plant rationally, and leads to lower economy of desulfurization system. Keywords: Desulfurization power price; Wet flue gas desulfurization system; Cost and benefit analysis 1.
Convective pass sorbent injection is the flue gas desulfurization process where Ca(OH)2 is injected in the medium-temperature range of 425650 Deg C, which usually occurs in the convective tube section of a boiler in the vicinity of the economizer.
