Non-bio to bio

A sustainable alternative to fossil fuels

Biomass is regarded as a carbon-neutral, renewable alternative to fossil fuels.

In many countries, there is a strong political desire to implement renewable energy and to convert to biomass-based energy generation via economic incentives.

And since SO2 and NOx emissions are lower for biomass than most fossil fuels, converting a fossil-fired boiler to biomass can reduce or even eliminate the cost of complying with current and future legislation. 

An additional advantage is that a biomass conversion can allow for older units to operate for an extended period under conditions that are both profitable and environmentally sound.

Existing coal, HFO and gas boilers can be converted to biomass firing, based on biomass pellets, wood chips or agro residues. This requires an upgrade of the fuel supply and preparation system as well as an evaluation of the boiler suitability and any necessary modifications. In most cases current fuels can be maintained along with the biomass, increasing the boilers fuel flexibility.

We have great experience in boiler conversions of all types, including conversion from one fuel to another, life-extending retrofits such as the replacement of drum and heating surfaces, or an exchange of old firing systems with modern, efficient low-NOx firing systems.

Boiler conversion


  • life extension
  • efficiency improvement
  • capacity increase
  • fuel conversions
  • low-NOx firing systems

We would be pleased to take the overall responsibility for conversion assignments - even for boiler plants which were not originally supplied by us.

Let us take the conversion of your boiler plant in hand - we have the necessary expertise so you can rest assured that the change will be a profitable investment.
