Does anyone know whether it’s better to have the outlet of a boiling furnace at the top or on the side? If the outlet is on the side, will it affect the effective volume of the furnace, and to what extent? (This device is used for acid production from pyrite, utilizing mixed ore in the production process.)
The outlet of a boiling furnace is generally located on the side, which helps to reduce stress damage to the entire top section； The effective volume of the furnace has little impact.
Thank you for your answer. But since the outlet is on the side, it seems like the gas might take a shortcut and exit the furnace more quickly, which could affect the residence time of the gas inside the furnace? At the same time, it seems that most of the area on the opposite side of the outlet and at the top cannot be utilized either, which affects the effective volume. Could this be the case?
All our current approaches involve moving from the top, but stress is indeed a problem
I think that in modern small furnaces, the outlet is often located at the top, but in larger furnaces it is usually placed on the side of the furnace. This arrangement makes it easier to connect pipes, while also ensuring the strength of the furnace’s top portion. If the outlet were at the top, the size of the opening would be highly restricted; as a result, the gas flow speed would be high, causing greater resistance and an increased risk of blockages.
