Description:
The paper gives results of pilot plant experiments of particulate collection by a venturi scrubber downstream from an electrostatic precipitator (ESP). The data, which cover a range of scrubber operating conditions and ESP efficiencies, show that particle collection by the venturi scurbber is not affected by the upstream ESP; i.e., for a given scrubber pressure drop, particle collection efficiency as a function of particle diameter is the same with the ESP both on and off. The experimental results are in excellent agreement with theoretical predictions. Order of magnitude cost estimates indicate that particle collection by ESP scrubber systems may be economically attractive when scrubbers must be used for SOx control.
