Two banks of cyclones in series with each bank containing 4 cyclones that can be described as type 3 conventional cyclones with a body diameter, d = 5 m (text table 4.2) are used to treat the pm emissions from the power plant. the total gas flow is 500 m3/s, the pm2.5 uer is 40 kg/h, and the fly ash particle density, ρp= 2300kg/m3. assume the maximum particle diameter for particles > 15 μm is 30 μm and calculate treatment efficiencies using the maximum bin diameter value rather than average bin diameter value. 1. determine the % mass removal in the first bank of cyclones and the resulting cumulative mass fraction psd. 2. determine the % mass removal in the second bank of cyclones, overall % mass removal, and the treated cumulative mass fraction psd. 3. would more cyclones in each bank result in greater treatment efficiency? why? 4. would using the same number, but larger cyclones result in greater mass removal efficiencies? why? 5. what is the primary disadvantage or drawback to increasing mass removal efficiencies by changing the number or size of the cyclones?
