Classification procedure of the explosion risk areas in presence of hydrogen-rich syngas: Biomass gasifier and molten carbonate fuel cell integrated plant

This paper deals with the safety aspects of a 500 kWth (thermal power) biomass gasification plant coupled with a 125 kWe (electric power) molten carbonate fuel cell. In particular, it describes the procedure for assessing the explosion risk in presence of hydrogen-rich syngas and compares the results given by the application of technical standards with those obtained by the implementation of a fluid dynamic model for the potential emission scenarios.
