NextBAT® for higher efficiency and lower emissions
The next generation of Best Available Technology standards (BAT) will be presented in the coming waste incineration BREF in 2013. The revised BREF will set new and higher standards for waste-to-energy plants in terms of higher efficiency and lower emissions.
NextBAT® is the Scandinavian solution to the next generation of Best Available Technology.
Babcock & Wilcox Vølund and Götaverken Miljö have a long tradition for focus on high efficiency and low emissions, and together we have a solution for future waste-to-energy plants.
Higher plant efficiency with NextBAT®
A waste-to-energy plant’s level of efficiency in recovering energy from waste is measured by the R1 formula. High overall energy efficiency ensures maximum substitution of fossil fuels and thereby reduces the impact of greenhouse gases (GHG).
NextBAT® ensures that plant owners achieve a high R1 rate because of our unique technologies:
- DynaGrate® is the most advanced grate on the market renowned for its maximum burnout.
- Water-cooled wear zone minimizes slag built-up in the combustion zone.
- Inconel® in furnace walls provides high protection against corrosion.
- ACC (Advanced Combustion Control) maintains a stable combustion process by controlling the coefficient of resistance and combustion air.
- CFD simulation is an effective method for achieving the most efficient design and heat transfer in the boiler.
- RESOX™ is a unique technology for decreasing the corrosion rate for super heaters or for allowing higher steam temperature thereby increasing the electricity production.
- The flue gas condenser recovers an additional 20 – 25% of energy by condensing the water vapour.
From crane to stack NextBAT® technologies:
Unique and reliable technologies that bring several environmental benefits:
- ADIOX® is a widely recognized method to remove dioxins and prevent memory effect.
- CUTNOX™ reduces the initial NOx-formation at combustion by injecting water and air into the furnace.
- MERCOX™ removes mercury, primarily at plants with a high level of metallic mercury in the flue gas.
- Multi scrubber – a compact and highly effective wet flue gas cleaning system.
- VoluMix™ forms a complete burnout in the gas phase by injecting secondary air into the combustion zone.
- WESP removes ultra-fine particles and aerosols.
