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.
Energy-from-waste is a way to recover valuable resources
Energy from waste (EfW) 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:
Did you know that there is a clean alternative to landfills?
A proven technology with measureable results.
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:
TECHNOLOGIES
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.
Compact, space saving solutions suitable for rough conditions
B&W Loibl's conveyance systems can be ordered in various shapes, designs or materials depending on need and conveyor arrangement. These environmentally friendly systems reduce emissions and are engineered for high operational safety.
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.
Each waste-to-energy (WtE) plant has a unique profile and achieving full potential requires a tailor-made business model. Having supplied more than 500 WtE plants worldwide, 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.
