Air supply volume for incineration of sulfur recovery exhaust gases
Thread Content
I’m seeking advice from fellow sailors: how does everyone calculate the air supply volume for the sulfur recovery flue gas incinerators?
A reasonable assumption is to take the oxygen content in the flue gas to be around 3%. For example, in our system handling 7,000 cubic meters of flue gas, 100 cubic meters of gas are burned; burning that gas requires 1,000 cubic meters of air. If 2,000 cubic meters of air are supplied, then the excess 1,000 cubic meters of air contains 210 cubic meters of oxygen. 210/7,000 = 3%.
Thank you:handshake
The overall air distribution is related to the temperature control of the flue gas in the furnace; it involves gas, air, and exhaust gases, with the temperature generally ranging from 650°C to 800°C. Burners generally control the air volume at a gas equivalence ratio of 70%. Secondary air enters the furnace.
