An increase in the population on the Faroe Islands leads to more waste which raises incineration requirements. LBP Engineering has contributed to the installation of a new plant to increase capacity and secure a more stable combustion.

An aging combustion oven needed to be upgraded and the adjoined boiler replaced in the town of Leirvík on the Faroese island of Eysturoy – just across the sea from Klaksvík. Both furnace and boiler are part of the municipal incineration system on the Faroe Islands and were originally designed to incinerate 2.5 tons of waste every hour. However, an increase in the population and the related increase in waste amounts necessitated an increase in capacity on the plant in Leirvík.

“The plant mainly handles industrial waste and is solely for incineration purposes as there is no central heating on the Faroe Islands, except in Tórshavn. The old incinerator lacked in stability and had a very limited capacity. It just was not powerful enough in terms of incineration. There were also issues related to overpressure in the furnace and boiler. We have now established a much more stable combustion and have also made it possible to increase the incineration capacity. At the same time, emissions can be kept at a lower level than before,” explains LBP engineer Anders Hovmand who has been in charge of commissioning the new plant.

Thanks to the new furnace and the upgrade of the boiler, capacity has been increased to 3.5 tons of waste per hour, and daily maintenance of the plant is a lot easier than before. Furthermore, due to LBP’s installation of frequency converters on just about all pumps and fans, the plant is not only more stable, but also a great deal more energy efficient. Finally, the plant has been redesigned to forward two-thirds of the heat generated to a neighbouring factory. Here, the heat is utilized to dry fish whilst any surplus heat is used for purification and recycling of waste oil in another building.

For an assignment like this, it is of the utmost importance that everything is sized correctly so that single parts are not overloaded. In this project, LBP Engineering functioned as a coordinating link between the client and the many different craftsmen involved, particularly electricians.

“It has been a fun job which in many ways displays the width of our services – all the way from process design and automation solutions to commissioning of the plant. It is one thing to assure the right dimensioning and the right level of technicality, but also, on a judicial level, it has been both interesting and challenging to participate in assuring the quality of our client’s endeavours. It is also always quite the experience to visit the Faroe Islands,” says Anders Hovmand.
