Study of the gasification process with oxygen and carbon dioxide for the integration of a fluidized-bed biomass gasifier connected to an oxycombustion boiler. Basic engineering design of the gasifier (DOTGE)

Summary: The aim of this Project is to design a fluidized-bed gasification system which can operate connected close to an oxycombustion boiler. The process is noteworthy compared to conventional gasification as it can optimize the composition of fluidizing agent (CO₂/O₂ ratio) and the temperature of the gasifier. It will be constructed in the “Ciudad de Energía” (CIUDEN) (Ponferrada, León). During the first phase, the design and construction of the gasifier island for autonomous functioning will be carried out. In later phases, the gasifier will be connected to the oxycombustion boiler and a gas cleaning system to feed the combustion engine to produce electricity will be constructed.
