Jernforsen is one of Europe’s leading companies within the field of biomass heating technology with over 1,000 plants delivered across the world since 1984. Jernforsen work in the range of 2MW to 35MW thermal output and can supply components or complete turn-key solutions.

Scandinavian technology generally has deserved reputation for using high quality components, building robust equipment which is very reliable and gives high availability. Process industries appreciate these qualities and Jernforsenʼs regular customers are sawmills and other wood processing industries, the paper and pulp industry, town district heating systems and utility energy suppliers. In the recent past, biomass
plant for pellet production and (steam) Combined Heat and Power has become more common.

Applications include hot water or steam boilers for:

District Heating:
where efficiency and environmental constraints are the key factors for low operating costs, many of these systems have flue gas condensers to increase the efficiency of the plant and give low emissions.

Sawmills and Processing Industries:
where the ability to use poor quality fuel is important together with have high availability with only (annual) scheduled down time for service and maintenance.

Combined Head and Power:
via a high pressure boiler which can produce steam up to 25tonnes per hour at 480°C into a one or two-stage turbine, depending on the end use with optimisation depending on the back pressure or condensation design.

Drying plants:
to dry anything from sawdust for pellet production to grass for livestock winter feed pellet production. The drying plants can be designed to produce either hot drying gas between 300-500°C or as steam systems that supply continuous kilns or converted rotary kilns.

Waste Reduction:
Scot Heat & Power are able to provide WID compliant furnaces with infeed systems that can handle a wide range of waste fuels. Waste Fuel Use / Waste Combustion / WID Compliant. Different strategies can be used to deal flue gas emissions from simple multi-cyclone dust arrestor to electrostatic precipitators with NOx, such as Selective Non-Catalytic Reduction, and flue gas treatments to reduce emissions of Sulphur Dioxide (SO2), Hydrogen Chloride (HCl) and Hydrogen Fluoride.
