Gasification - Wikipedia

Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in

Fluidized Bed Boiler - an overview | ScienceDirect Topics

Due to the bed material inside the boiler, fluidized-bed boilers have high heat transfer coefficients, utilize the entire boiler volume, have a uniform temperature distribution and have a low stable combustion temperature. Fluidized beds are capable of burning very wet fuels and fuel particles of sizes up to 80 mm (van Loo and Koppejan, 2006
