Biomass fuels

We have more than 30 years of experience with an array of biomass fuels. Biomass is renewable, carbon-neutral, cost-effective, and readily available.

Using biomass to generate energy is by no means a new concept. It started when man rubbed two sticks together and created fire. Throughout civilisation and throughout the world people have used nature’s materials for heat, cooking, and production.   

Today, solid biomass fuels are available from a large number of sources including sawdust, wood chips, peat moors, bark chips, rape, wheat straw, bagasse, palm oil residues, etc. These fuels are made up of agricultural by-products, forest residue, paper and sawmill residue, animal farm litter, recycled materials, and any number of other sources.

Wood, pulp, and paper industries can recover CO2-neutral energy from their own bio waste products.

Biomass fuels

Yet it is precisely the fact that there are so many sources that makes biomass a difficult fuel. Understanding the physical characteristics and chemical compositions of every source is essential in order to fully optimise the conversion of biomass into heat and electricity.

Overview of physical and chemical properties

Fuel characteristics:

In general, biomass fuels are evaluated on the basis of their physical and chemical properties. Here are the key properties:

Physical properties

  • Density
  • Size distribution
  • Humidity
  • Foreign matter

Chemical properties

  • Calorific value
  • Proximate analyses
  • Ultimate analyses
  • Ash analyses
  • Ash-melting behaviour

After examining the physical properties of the fuel, we can determine the type of stokers and grate system needed. The chemical properties and specific needs determine the design of the boiler. These are important parameters for avoiding fouling and corrosion. The correct design can help extend lifetime, reduce maintenance costs, and increase availability of your biomass energy plant.

Biomass is the preferred choice

For many years, biomass has occupied an undisputed first place in the choice of renewable energy sources. It outstrips wind, water, and solar energy by several lengths. Consumption in the EU alone has increased by more than 60% over the past 10 years.

In Denmark, which is one of the EU’s pioneers in the field of sustainable energy, 15% of all electricity and district heating is already produced with the help of alternative energy. In this respect, biomass accounts for as much as 70% of total green energy consumption – consumption that is expected to increase in Denmark, the EU, and the rest of the world.

A climate-friendly fuel

As opposed to coal and fossil fuels, biomass is green. It’s CO2-neutral, since it generates only the amount of CO2 that the plant absorbed while growing. 

Generating energy from biomass not only lives up to the increasing global demand to reduce emissions, but can simultaneously recycle biological waste from many forms of production, thereby solving serious problems with waste. So, biomass energy resolves two critical environmental issues at once.

Financial incentives for reducing greenhouse gases

In many countries, initiatives for reducing greenhouse gases have lead to energy policies that include tax reductions and/or subsidies which encourage and support the use of biomass. This is why a biomass facility can also be a good investment for the future.

Technology opens doors

An increase in the use of biomass is very much due to the major advances being made in biomass technology.

The development of more reliable plants, optimised pre-processing, and combustion methods have improved utilisation rates, and research into the possibilities of generating energy from biomass have already yielded results that bode well for the future. Even after several thousand years, biomass still has tremendous, unused potential that modern technology will continue to ensure we all benefit from through a cleaner environment.

30 years of working with biomass

We have been on the forefront of converting biomass into heat and electricity. Our knowledge goes back three decades. As a pioneer of this technology we have supplied systems to more than 50 biomass plants worldwide. Our expertise covers a wide spectrum of biomass, including wood chips, pellets, sawdust, wheat straw, barley, rice straw, bark, and bagasse. We have been on the cutting edge of everything from grates and feeding systems to furnaces and boilers, and continue to push the envelope in developing even more efficient technology.
