Electrostatic precipitator plate spacing

Consider a parallel-plate electrostatic precipitator across which a 10 kV potential is applied. The interplate spacing is 1 cm. The particle density is 2,000 kg/m3. The total surface area is 10 m2, and the flow rate is 0.5 m3/s. Use the test results provided in Table P7.2 to estimate... 

An electrostatic precipitator (ESP) is being used to clean fly ash from a gas. The precipitator contains 30 ducts, with plates 12 ft high and 12 ft long. The spacing between the plates is 8 in. The gas is evenly distributed through all of the ducts. The following information can be used ... 

Fractional efficiency curves describing the performance of a specific model of an electrostatic precipitator have been compiled by a vendor. Although you do not possess these curves, you are told that the cut diameter (50% efficiency) for a precipitator with a 10-in. plate spacing is 0.9 pm. The vendor claims that this particular model will perform with an efficiency of 98% under your operating conditions. You are asked to verify this claim and to make certain that the effluent loading does not exceed 0.2 gr/ft. ... 

A single-stage duct-type electrostatic precipitator contains five plates that are 10 ft high, 20 ft long, and spaced 9 in. apart. Air contaminated with gypsum dust enters the unit with an inlet loading of 53 gr/ft and a velocity through the unit of 5 ft/s. The solids bulk density is 47 Ib/ft. ...
