Seeking advice from experts on equipment selection
Thread Content
I would like to ask the experts on this platform: For enamel reactors of the same volume, for example, those with a capacity of 5 cubic meters, the heat exchange area of the jacket is around 12 square meters. If external semi-coil tubes are used, the heat exchange area drops to just over 7 square meters. With the same heat transfer medium, which option is better? I hope experts can give me some advice.
The heat exchange efficiency of jacketed enamel reactors is usually better than that of those with external semi-coil tubes, due to the larger heat exchange area. However, when making a actual choice, factors such as process requirements, medium properties, and cleaning maintenance also need to be considered. If high heat exchange efficiency is required, a jacketed type can be chosen ； If cost and ease of maintenance are considered, the outer half-coil can be chosen. The specific situation needs to be considered comprehensively in light of the process requirements. .
It’s not necessarily the case that one is better; factors such as area as well as the heat transfer coefficient come into play. Also, is the manufacturing capacity for the external coils of the enamel-lined tank sufficient?
Obviously, a jacket is better; coiled tubes have a low heat transfer coefficient and a small surface area – it depends mainly on the requirements
As long as the area is sufficient, the outer half-tube should be preferred.
The outer half-tube has high heat transfer efficiency, a small area, high manufacturing difficulty, and high cost.
