Modelling, validation and long-term testing of operational properties of staged gasification plant at fluctuating electricity and heat output

The project increased insight into gasification plants based on the Open Core principle. Tests were made on the Castor unit at Græsted Fjernvarme. The overall activities included: - rebuilding and testing the system for operation at part load - test and development of system start/stop procedures - operational measuring at the rebuilt CHP unit - development of a static computer model The project showed that the system can be regulated downwards to 40% of maximum output. The measuring programme showed that reasonable gas with a fairly stable composition can be produced.
