Project description
Babcock & Wilcox Renewable Service was given the task of upgrading the furnace and replacing the hot water boiler at Leirvik waste-to-energy plant in the Faroe Islands. The plant dates back to 1989 and was originally designed for 2.5 tons of waste per hour. The purpose of the plant upgrade was partly to increase the capacity of the plant and to extend the service life. The capacity was raised to 3.5 t/h, 12 bar and 140 °C and is expected to extend its useful life.
