Feeding Biomass into Pressure and Related Safety Engineering

摘要

Malfunctions in the fuel feed and handling equipment could be cause for biomassgasification process upsets, and are of major concern for pressurized gasification processes. One precondition for the development of handling and feed equipment for solid fuels and wastes and for the design of novel systems is a good knowledge of the characteristics and flowability of bulk materials, because the requirements for the equipment reliability, adjustability, economy, and lifetime are becoming more demanding. Safety engineering, including fuel flow characteristics, and dust explosion and spontaneous ignition properties, is also discussed with special attention given to the conditions in pressurized feeding systems. Results from dust explosion and spontaneous ignition tests with biofuels at elevated pressures are presented.
