Return line of condensates

Heat exchanger intended for cooling of a high flow of water coming from the return line of condensates.

The engineers of SACOME technical department have received a request to design a heat exchanger intended for the cooling of a high flow of water – around 100 m3 / h – coming from the return line of condensates in a steam line, being the capacity required 800 kW. Due to the configuration of the project, it is required to transfer the current flow through the shell of a tubular heat exchanger, while the cooling water does it through the inner tubes.

Since the customer expects a high level of fouling in the shell side, due to possible fouling in the return of condensates, we have proposed a removable tube bundle multitubular design with corrugated inner tubes; our I-TFM-D heat exchanger. This design allows easy access to the shell channel for inspection and / or cleaning, while promoting a high turbulence regime that favours heat transfer.

After the installation and commissioning of this corrugated tube heat exchanger, SACOME technicians have received the client’s congratulations. Thanks to the correct dimensioning of the heat exchanger, the equipment reaches the required temperatures easily, which has allowed the customer to reduce the cleaning and maintenance works, with the cost savings involved.
