SPRING G2E: Bubbling fluidised bed plant for air gasification of residual biomass feedstocks
Application sectors
Problem to solve
Power generation from biomass is currently based on downdraft fixed-bed reactor technology, which works well especially with woody biomasses of a residual nature, with relatively narrow specifications (e.g. wood chip size, moisture and ash content relatively low) and on small sizes. The proposed boiling fluidised reactor technology, on the other hand, allows a broader spectrum of materials that can be fed to the reactor and is also more flexible with respect to plant size (small to medium).
Description
The plant consists of the main sections relevant to the production of a syngas suitable for powering an internal combustion engine (ICE), i.e. engines capable of working with a fuel gas of low calorific value (4.5-6.0 MJ/Nm3secco). It operates at temperatures of 800-850 °C and uses air as the gasifying agent. The plant can be operated continuously; it is equipped for monitoring and acquisition of process parameters and along plant sections.
Innovative aspects and advantages
- Bio-H2 production (H2 of renewable origin);
- Biofuels production (liquid and gaseous);
- Carbon-neutral power generation;
- Higher electrical efficiency via FC;
- Cylindrical layout;
