Abstract (en)
This invention relates to a fluidised bed unit for use in thermally treating biomass, waste, dried sewage sludge or by-products in general. The application is to be intended not limited to thermal treatments but has to be intended extended to any application involving a fluidised bed reactor.The unit forms part of a larger system including a forced draft fan and an induced draft fan suitable to maintain the reactor operating temperature and pressure. The system is suitable for installation on a small or medium scale installation in the range 500kWth - 3Mth for thermal treatment application or in general in the range 10kg/h to 1000kg/h of feedstock. The unit comprises three cylinders arranged in an inverted "U" shape hereafter described.The first cylinder is vertical and comprises a feedstock inlet, a fluidisation agent inlet, a nozzle inlet box, a plurality of nozzles for injecting the fluidisation agent in the bed, a plurality of temperature and pressure sensors. The flow in the first cylinder is upward.The second cylinder is horizontal and comprises a flue gas temperature control device and an explosion protection device. The flow in the second cylinder is horizontal moving from the first cylinder toward the third cylinder.The third cylinder is vertical and comprises a temperature control device, a catalytic filter, an auger for feeding new catalyst and extracting exhausted catalyst, and trapped particles, a plurality of temperature and pressure sensors. The flow in the third cylinder is downward.The fluidised bed unit is compact, relatively simple to maintain and commercially viable so that it may be skid mounted in the factory and transported to the installation site.The fluidised bed unit can also be part of an energy conversion system that is suitable for installation on small and medium scale processing plants.
