How to design steam condensation
Thread Content
In a certain company, the processing procedure requires the materials to be steamed for half an hour, with a pressure of 0.6 MPa during steaming. After the steaming process is complete, the steam must be released, and the material then undergoes the next stage of processing; it is an intermittent operation. When steam is released, a small amount of material is carried away, resulting in an unpleasant odor in the environment. Due to environmental inspections, it is planned to condense this steam into water for treatment. It is calculated that this amount of steam is approximately 12 cubic meters at a pressure of 0.6 MPa. Question: If coil condensation is used, what should be the heat exchange area of the coil? How is the cooling water inflow volume determined? A reward of 20 Haichuan coins is given for reposting this thread.
How long does it take to release air from a volume of 12 cubic units? There is a big difference between releasing it instantly and doing so over half an hour. What is the best approach – to use submerged coiled tubes or spray coiled tubes? If the deflation frequency is not high, slow cooling by immersion will suffice
Submersion coil condensation. Venting time: within half an hour
To condense 12 cubic meters of steam in half an hour, approximately 1 m² of condensation coil is required.
It sounds a bit like a rubber vulcanization tank. It’s quite interesting to analyze this issue in detail – for example, is the opening degree of the steam release valve fixed, or is it used to control the rate of pressure reduction?
