Suppose you have an electrostatic precipitator currentlyoperating at 90% for 3 µm diameter particles and you need toincrease the efficiency to 98% to comply with your operatingpermit.
a. Using the Deutsch equation, identify three parameters youcould change in order to increase your efficiency. By whatpercentage would you have to change each separately to achieve yourgoal?
b. Suppose that you decide simply to add a cyclone in serieswith the ESP in order to reduce the PM concentration in the fluegas, rather than changing the ESP parameters as in part a. Whatmust the control efficiency of the cyclone be in order for thecombined control efficiency to be 98%?
c. For most of the course we have assumed PM as solid,spherical particles with a density of 2200 kg/m3. Suppose ourcontrol system must capture particles of zinc with a density of7140 kg/m3. How much will this alteration increase or decrease theefficiency of our combined ESP-cyclone system?
