Air Assisted Flare Question
Air Assisted Flare Question
(OP)
Can anyone give me an idea of how much excess air is typically used for an air assisted flare? I am trying to reverse engineer a smokeless flare design. I calculated the stoichiometric air requirments for our design and by using the design capacity of the blower I came up with over 300% excess air. That seems high to me. I suppose that it is possible that the designer used a little brute force and supplied us with a blower that far exceeds our design needs. I wish that he would have done as much for the tip
Is there a good reference manual for flare design available for purchase?

To get stoichiometric I used this formula in a spreadsheet to get #/hr rqd at 50% excess air. Did I miss something?
28.964*(C1mols*2)+(C2mols*3.5)+(C3mols*5)+(iC4mols*6.5)+(nC4mols*6.5)+(iC5mols*8)+(nC5mols*8)+(C6mols*9.5)*(1.5)
The component multipliers were derived from:
2CnH(2n+2) + (3n+1)O2 ---> 2nCO2 + (2n+2)H20
Thanks
