Aug 11, 2018· Limestone slurry is prepared mixing fine limestone powder with water in a slurry preparation tank. Sorbent slurry from this tank is then pumped into the absorber reaction tank. The absorber is a counterflow tower with flue gas flowing upwards, while limestone slurry is sprayed downwards by an array of spray nozzles.
The mixer assembly conveys conditioned limestone powder from a surge hopper located below the silo discharge, slurries the powder with water on a single pass to 30%+ solids and discharges the slurry into the slurry storage tank. Slurry makeup is on demand based on slurry storage requirements.
1. slurry preparation system. The tank car is used for conveying the lime powder to the lime silo, and the lime powder is quantitatively sent to the lime slurry tank through weighing belt conveyor to form slurry. Then the slurry is pumped to the inlet of absorption tower circulating pump.
Flue gas desulfurization (FGD) processes are usually categorized as wet and dry or semidry systems. In wet FGD processes flue gas is contacted with a slurry consisting of a sorbent in an aqueous medium, such that the flue gas is cooled to the adiabatic saturation temperature. Whereas, dry and semidry FGD processes involve injection of a
Wet Flue Gas Desulfurization (FGD) Systems . A typical lime/limestone Flue Gas Desulfurization (FGD) system consists of three major subsystems: The reagent (lime or limestone slurry) preparation; The scrubber/SO2 absorber and mist eliminator, and slurry/solid waste disposal systems. Get price
The chemical reactivity of lime slurry along with the fineness of the suspension will depend on the slaking temperature. This temperature must be as high as possible and, therefore, involve a minimum amount of added water. quick lime in powder form.
