Information related to plate-type air-cooled condensers
Thread Content
Today, I need to design a plate-type air-cooled condenser for the condensation of waste steam from turbines. I have only designed tube-type condensers before; this is my first time working with plate-type designs. I wonder if anyone here has designed similar equipment? I would like to exchange ideas or discuss this with those who are familiar with it. If you have any relevant information, I would appreciate it if you could share it. Thank you.
Copper tube types are commonly used in power generation turbines. I’m not sure what the conditions of the waste steam from your turbine are; if the temperature is below 250 degrees and the pressure is below 2.5 MPa, a fully welded plate type can be used directly. If the temperature is slightly higher and the pressure is also slightly higher, it’s possible to first use a tube type and then a plate type. I’m not sure if it’s used in turbines; it’s often employed in heating boilers or for domestic hot water.
Returning to the 2nd floor, the temperature of the waste steam is around 50 degrees, and the pressure is near vacuum. It uses a fully welded design, but with type A plate bundles. It is similar to a tubular air-cooled direct condenser, except that plate bundles are used in place of tubes; however, the area, flow rate, and arrangement of the elements differ significantly from those in tubular designs. That’s where the difficulties lie.
Can LZ provide you with information on the tubular condenser you designed?
eddy-8280103: Please provide an approximate flow rate for the waste steam. We use plate-type gas coolers for the recovery of waste steam, and based on the temperature you mentioned, one stage of cooling is sufficient; two stages are not necessary. Please refer to the information on my plate-type gas heat exchangers (condensers); their efficiency is 3–5 times that of tube-type ones. http://bbs.hcbbs.com/viewthread.php?tid=540367&highlight=%B0%E5%CA%BD%C0%E4%C4%FD%C6%F7 I can help you calculate it. Question: eddy-8280103, don’t you also produce plate-type air coolers? How big is the difference between us?
Return to floor 5: waste steam flow rate is 15,200 kg/h, inlet temperature is 54°C, and inlet pressure is 0.02 Mpa. It is necessary to consider the arrangement of the forward and reverse plate bundles.
