Waste to Energy
for a Sustainable, Circular Economy

What is Waste to Energy?

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:

  • There are nearly 100 WtE plants in North America,
  • more than 500 operating in Europe
  • and 1600 plants in Asia.

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:

  • Avoids methane emissions from landfills
  • Offsets greenhouse gas (GHG) emissions from fossil fuel electrical production
  • Recovers/recycles valuable resources, such as metals
  • Produces clean, reliable base-loaded energy and steam
  • Uses less land per megawatt than other renewable energy sources
  • Sustainable and steady renewable fuel source (compared to wind and solar)
  • Destroys chemical waste / conventional HAPs
  • Results in emission levels well below permitted levels
  • Catalytically destroys NOx, dioxins and furans

A proven technology with measureable results.

Waste-to-Energy Steam Generation

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:

  • Destroys dioxins and furans
  • Minimizes formation of NOx and CO
  • Minimizes unburned carbon

TECHNOLOGIES

Combustion Grates & Stokers

Combustion Grate
In a waste-to-energy plant, the grate is where waste is converted into energy – the heart of the system. As such, grates are a significant focus area for us. Over the past 80 years we have supplied more than 500 combustion grates worldwide. Many of our older grates are still in operation, running efficiently and living up to current environmental standards. 

Waste Fuel Feeder Systems

Fuel Feeding Systems
Steady and continuous feeding of fuel in waste-to-energy plants is the key to stable operation, maximum efficiency, and lower operational and maintenance costs.  

Water-Cooled Wear Zones

Water-Cooled Wear Zones

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.

Energy Recovery

L90 Waste-to-Energy Plant
B&W Vølund’s highly efficient waste-to-energy plants obtain a total recovery of 99%. In existing plants our flue gas condensation can increase energy recovery by 20-25%. Improved revenue, reduced greenhouse emissions, and a more positive image are three of the benefits that come from extended energy recovery by condensation of the hot flue gases.

VoluMix Systems

VoluMix
Proper, turbulent mixing of the flue gases in the boiler furnace provides a better combustion process and burn-out in the gas phase. With the B&W Vølund VoluMix™ system, all of the primary air passes through the narrow gap between the grate bars, creating a strong, turbulent combustion zone.

Emissions Control

SCR Systems
As a single-source supplier, we can develop an integrated multi-pollutant strategy to match your long-term requirements.  Through every phase of the project, we take the time to determine your needs and recommend a customized solution.
