摘要:
A batch feeding apparatus of biomass to a gasifier is described. A casing is equipped with an inlet of the biomass, also provided in bulk by outside means, and with an outlet of a biomass load towards the gasifier. A transferring element has the function of transferring the biomass from the inlet to the outlet of the casing itself. The transferring element in turn comprises a compartment to temporarily collect a corresponding quantity of biomass. The transferring element is inserted in the casing and is movable with respect to the latter between an initial position, at which the collecting compartment is aligned with the inlet to receive a biomass load, and a final position at which the collecting compartment is aligned with the outlet, to unload the biomass load to the gasifier. A compacting piston is provided for in the collecting compartment.

摘要:
A turbine (1) of an Organic Rankine Cycle ORC, comprising a shaft (4) supported by bearings (8) and a plurality of seals (10, 11) arranged around the shaft (4) for confining the operating fluid expanding in the turbine, is described. The seals are arranged so that to define and preserve the insulation of a first chamber (101), a second buffer chamber (102) and a third chamber (103). The first chamber (101) is between the expansion stages of the turbine and the buffer chamber (102), and the third chamber (103) is between the bearings (8) and the buffer chamber (102). A barrier fluid (302) is fed into the buffer chamber (102). Advantageously, the barrier fluid (302) is the same organic operating fluid fed to the turbine. An ORC Rankine cycle plant comprising said turbine as well as a method for confining an operating fluid in a turbine working in an Organic Rankine Cycle ORC is provided.
