Biomass Conversion

Biomass is a renewable and carbon-neutral energy source, and as such it is a sustainable alternative to fossil fuels. There is a strong political desire to implement renewable energy supply in many countries. This has led to economic incentives for biomass-based energy generation.

Furthermore, the emission of especially SO2 and NOx tends to be lower for biomass than for fossil fuels. Therefore a biomass conversion of a fossil fired power station can reduce or even eliminate the cost of complying with current and future legislation.

An additional advantage is that a biomass conversion allows 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, typically based on biomass pellets or wood chips. 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 original fuels can be maintained and this increases boiler fuel flexibility.
