How to determine the size of the overflow opening in a boiling furnace
Thread Content
Our company is constructing a 70 square meter boiling furnace. The current size of the overflow opening is 540*720, which seems quite small when viewed on site. I would like to ask if anyone has a specific calculation method for determining the appropriate size of such an opening?
When the hot calcine in the furnace is boiling, it behaves like a liquid; due to the difference in density, it flows toward lower areas. You can calculate the flow rate per hour using the density of water and a flow velocity of 0.6 meters per second. The thickness of the overflow can also increase as the amount increases, just like in the Three Gorges Dam.
