Questions about the tail condenser
Thread Content
The tail condenser converts 60-degree saturated steam into 40-degree condensed water, which is then heated to 40 degrees using 30-degree cooling water. Since heat exchange is between steam and water, bare tubes are used. But some people say that by replacing the straight tubes with finned tubes, the heat exchange area per tube increases, which means fewer tubes are needed. Is this feasible? Is it necessary to use finned tubes for heat exchange between steam and water?
It’s not necessary. The use of plain tubes in heat exchangers for heat exchange between steam and water is a perfectly normal design.
Then, would using finned tubes help reduce the number of heat exchange tubes?
Yes, the fin components must have a high manufacturing cost; the original poster should consider all factors.
Okay, thanks for the explanation. I’ll compare them when the time comes and then I’ll know
