How many air caps are generally needed for a 200,000 tons/year boiling furnace?
Thread Content
I would like to ask the experts: In the design of a boiling furnace for producing acid from pyrite, how is the number of air nozzles determined? How many air nozzles are typically required for a boiling furnace with an annual production capacity of 200,000 tons? What is the general range for the spacing between the air nozzle holes in the deck?
Generally, the spacing between air caps in domestic installations is 140 units, arranged in a triangular pattern; there are two concentric circles around them. Each air cap has 6 holes with a diameter of 4.7 units. As long as there are enough air caps, that’s sufficient. The diameter of a 200,000-ton sulfuric acid furnace is approximately 7,500 units, so the total number of air caps needed is around 2,400. It’s easy to find the relevant drawings.
