Suppose you have an electrostatic precipitator currently operating at 90% for 3 µm diameter particles and you need to increase the efficiency to 98% to comply with your operating permit.

a. Using the Deutsch equation, identify three parameters you could change in order to increase your efficiency. By what percentage would you have to change each separately to achieve your goal?

b. Suppose that you decide simply to add a cyclone in series with the ESP in order to reduce the PM concentration in the flue gas, rather than changing the ESP parameters as in part a. What must the control efficiency of the cyclone be in order for the combined 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 our control system must capture particles of zinc with a density of 7140 kg/m3. How much will this alteration increase or decrease the efficiency of our combined ESP-cyclone system?
