Steam boiler plant with a 3.5 MW / 5t/h capacity, operating on oat shell pellets was commissioned in December 2017. This project was challenging and very interesting for our team as it was first in our history with such type of biomass. SC KOMFORTS GROUP realised this project in cooperation with OSMO KAULAMO Engineering Oy (OKE) and energy company Varkauden Aluelämpö Oy, the main purpose of this boiler plant is to supply the steam for the A-REHU Oy production facility and hot water for district heating in Varkaus, FInland.

Goal: The main goal was to organize effective and reliable steam supply for the A-REHU Oy production facility in Varkaus, Finland and hot water supply for district heating system. The equipment should be capable to maintain nominal capacity operating on the oat shell pellets as the main fuel. Taking into consideration the specification of the stated fuel, SC KOMFORTS GROUP designed and manufactured furnace which is fully capable to work on 100% oat shell pellets.
