Boiler Island Solutions

Unicon Biograte Citius, Unicon Biograte Altius and Unicon Biograte Fortius are boiler island solutions for power plants.

The three solutions produce electricity in the range of 2,5MWe to 10MWe, which ensures that steam production capacities and steam parameters are optimised for each project.

Our boiler island solutions are designed for sustainable energy generation, focusing on flexible utilisation of local renewable fuels, as well as innovative technologies and lifetime services.The solutions are high modularised and prefabricated, which makestransportation easy and the installation time at the site is short.

Citius Unicon Boigrate has a steam production capacity of 10MWth to 14 MWth, a steam pressure of 32 bar and an average steam temperature of 450ºC.

The Altius Unicon Biograte features a steam production capacity between 18MWth and 22 MWthSteam, an average pressure of 66bar, and a steam temperature of 480ºC.

Our Fortius Unicon Biograte operates with a standard steam pressure of 66bar, a steam temperature of 480ºC, and steam production capacity typically of 36MWth to 44 MWth.

Module-structure boiler plants

KPA Unicon boiler plants can be manufactured as module types. The modules are pre-assembled and tested at the workshop in Finland. They are dimensioned so that they can be transported by rail, sea or road. At the site, the modules are installed side-by-side and the plant is ready for commissioning. The module structure minimises the delivery time of the plant.

Boiler plant services

The company offers services for its own install base and also to other boiler plants. When KPA Unicon takes responsibility for operation and maintenance, customers can focus on their core business instead of the operation of their energy production units.

Plant monitoring systems

PlantSys is a plant monitoring system, enabling remote assistance and remote control according to customer needs, via the internet. End customers use PlantSys as plant automation control system or contract operation monitoring as a separate service.
