A heat exchanger for cutting power plant costs

DuroShell - A heat exchanger for cutting power plant costs

Installing the wrong heat exchanger in demanding power plant positions can lead to a high capital investment as well as increased expenses down the road. The choice of a heat exchanger is therefore about more than cutting downtime. It’s also about cutting costs.

Power stations have long relied on shell-and-tube heat exchangers for demanding applications, but their bulky design can make for a difficult and expensive installation. With a compact plate-and-shell design that’s up to five times smaller than traditional shell-and-tubes, Alfa Laval DuroShell offers a simpler – and more cost-effective – installation process.

That’s not the only way DuroShell can mean a lower investment for power plants. It can also perform condensation and subcooling in the same unit. For certain positions, such as boiler feed water heating, that means one DuroShell can do a job that would require two units for most shell-and-tubes and even for conventional types of plate-and-shell heat exchangers.

But for DuroShell, the upfront savings are only the beginning. Installing a shell-and-tube or conventional plate-and-shell heat exchanger may also lead to significantly greater total lifecycle costs. This is a product of repeated fatigue-related downtime that causes expensive maintenance and repair – not to mention a short operational life for the equipment.

DuroShell was developed with a robust construction that ensures unrivalled fatigue resistance even in the toughest positions in power plants. That means it will be up and running reliably, rather than creating added expenses. Furthermore, standard maintenance routines for DuroShell are simple and cost-efficient. And with a longer service lifespan, it will be many years before the time comes to invest in a new unit.
