Biomass gasifiers & co-firing systems
Gasification is a process that can find new value in traditional fuels such as coal, wood, and oil. More impressively, gasification can unlock the energy value of waste materials such as waste wood from construction, forest, lumber, and paper industries, as well as household waste from towns and cities.
The hot, low-calorific-value gas generated in Amec Foster Wheeler's gasifiers can be fed into a pulverized coal boiler as a secondary fuel to provide a low-cost, low-emission, efficiency-enhancing solution for existing capacity.
Combining gasification with co-firing in this way makes it possible to reduce consumption of a plant's main fossil fuel and cut CO2 emissions, increase fuel flexibility, reduce overall generating costs and contribute to greater renewable fuel usage.
Our experience has shown high gasifier availability with no adverse operating effects (fouling and corrosion) to the existing boiler.
