COMBUSTION FLUID-BED PLANT WHICH CAN BE FED WITH CONVENTIONAL AND ALTERNATIVE LIQUID FUELS

摘要

A boiling- fluid-bed combustion plant with limited thermal power (example 50 kW), supplied with liquid fuel both for start-up and for continuous operation, wherein the liquid fuel is supplied through an injector (2) that can be positioned at a variable height so as to be inserted completely or only partially inside the fluid bed. This enables variation of the thermal power continuously in a range comprised at least between 40% and 100% of the nominal power, without modifying the operating temperature of the bed (20), partializing the flowrates of gas -oil and fluidization air.
