Each waste-to-energy plant has a unique profile and achieving full potential requires a tailor-made business model. B&W can work with you to create the best model built on our proven technology.
Our specialists provide a wide range of services, improvements and upgrades to support useful lifetime of a waste-to-energy, biomass, multi-fuel or fossil fuel-fired plant.
Whatever your environmental solution requirements, however complex they may be, our engineers will work to find the right solution.
Ecologically Sound, Cost-Effective Energy Recovery
Waste-to-energy, including municipal solid waste and refuse-derive fuel, is a valuable renewable energy source.
With WtE plants successfully operating worldwide, the technology and environmental benefits are proven:
How waste-to-energy works
A waste-to-energy plant converts solid waste into electricity and/or heat - an ecological, cost-effective way of energy recovery.
A waste-to-energy - or energy-from-waste - plant converts municipal and industrial solid waste into electricity and/or heat for industrial processing and for district heating systems – an ecologically sound, cost-effective means of energy recovery. The energy plant works by burning waste at high temperatures and using the heat to make steam. The steam then drives a turbine that creates electricity.
Waste-to-energy is a way to recover valuable resources
Waste-to-energy isn’t just a trash disposal method. It’s a way to recover valuable resources. Waste-to-energy is a vital part of a sustainable waste management chain and is fully complementary to recycling.
Today, it is possible to reuse 90% of the metals contained in the bottom ash. And the remaining clinker can be reused as road material.
The results and benefits are proven:
PROJECTS & CASES
DENMARK
Located in Copenhagen, Copenhill / Amager Bakke sets new standards for environmental performance, energy production and waste treatment.
USA
In partnership with BE&K, B&W engineered, designed, procured and constructed SWA's Palm Beach Renewable Energy Facility No. 2. - one of the largest WtE facilities in the world. And through our subsidiary, we are providing O&M services.
IRELAND
For the first time in Ireland's history, in 2011 20,000 households in Meath County are provided with waste-powered electricity.
WASTE-TO-ENERGY TECHNOLOGIES
Mass Burn or Refuse-Derived Fuel (RDF)
B&W provides two boiler options when using waste as a combustion fuel. The first, known as mass burning of municipal solid waste, uses the refuse in its as-received, unprepared state. The second technique uses prepared refuse, or refuse-derived fuel (RDF), where the as-received refuse is first separated, classified and reclaimed in various ways to yield salable or otherwise recyclable products. The remaining material is prepared for firing in the boiler.
Combustion Technologies
B&W Vølund DynaGrate® pivoting combustion grate and Precision Jet® overfire air system – advanced designs provides environmental benefits during combustion:
Water-cooled wear zones are a revolutionary, efficient, and economical way to improve operational accessibility and productivity for waste-fired power plants.
Experiences from the 15 plants where we have installed water-cooled wear zones show that the total annual energy production has increased significantly – in many cases by as much as 25-30%. One plant is now handling 40% more waste after a conversion that includes the new wear zone technology.
