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.

A turbine (1) of an Organic Rankine Cycle ORC, comprising a shaft (4) supported by bearings (8) and a plurality of mechanical seals (10, 11, 18, 21) arranged around the shaft for confining the operating fluid expanding in the turbine, is described. The seal are arranged so that to define and preserve the insulation of four chambers arranged in succession along and around the shaft. A first chamber (101) is among the turbine expansion stages and the second chamber (102), named buffer chamber; a fourth chamber (104) is the nearest to the bearings and the third chamber (103) is in-between the second and the fourth chamber. In the buffer chamber a barrier fluid (302) is fed and, advantageously, it is the same organic operating fluid fed to the turbine. In this way the confinement of the operating fluid in the turbine and the respective non-contamination are guaranteed. A corresponding method for confining the operating fluid in a turbine is also provided.


A turbine is described for the expansion of a compressible operating fluid, for example gas or steam. The turbine comprises a first group of stages, named stages of first expansion, that extends in a radial centripetal direction in order to carry out a first centripetal expansion and a second group of stages, named stages of second expansion, that extends downstream of the stages of first expansion in order to carry out a second centrifugal expansion. The arrays of rotor blades of the stages of first expansion are constrained to a first shaft and the arrays of rotor blades of the stages of second expansion are constrained to a second shaft coaxial with respect to the first shaft, and are interposed between additional arrays of rotor blades constrained to the first shaft. The first shaft rotates at a speed higher than the second shaft, and in an opposite way. The rotors carrying the arrays of rotor blades are constrained in a cantilevered configuration to the respective shafts at an end thereof.

A turbine (1), at least partially centrifugal, for the expansion of a compressible operating fluid, for example gas or steam. At least one group of stages (5), named centrifugal stages, extends in a radial direction with respect to the axis X-X to carry out the centrifugal expansion of the operating fluid. Advantageously, the turbine comprises a group of stages, named centripetal stages (4), extending in a radial direction to carry out a first expansion of the operating fluid centripetally in the radial direction. Moreover, all the arrays of rotor blades are constrained to the shaft (2) at an end thereof, anyway not in the area between the bearings (9), i.e. according to a so-called cantilevered configuration and particularly advantageous to carry out maintenance operations. The proposed solution allows high efficiencies to be achieved by a compact turbine. A corresponding method for expanding the operating fluid is further described.

The scientific targets of the EUROSUNMED project are the development of new technologies in three energy field areas, namely photovoltaics (PV), concentrated solar power (CSP) and grid integration (GI), in strong collaboration with research institutes, universities and SMEs from Europe in the north side of the Mediterranean sea and from Morocco and Egypt from the south of the sea. The focus in PV will be on thin film (Si, CZTS) based solar cells and modules while the goal in CSP field is to design and test new heliostats as well as novel solutions for energy storage compatible with these technologies. The project aims at producing components that will be tested under specific conditions of MPC (hot climate, absence of water, etc.). Such investigations are complemented with studies on grid integration of energy sources from PV and CSP in Morocco and Egypt context. Additionally, the consortium envisages to train PhD students and Post-Docs in these interdisciplinary fields in a close and fruitful collaboration between academic institutions and industry from EU and MPCs. The consortium is well placed around leading academic groups in materials science and engineering devices and equipments for the development of PV and CSP, and also in the promotion of the renewable energies in general. Moreover, technology transfer and research infrastructure development in the targeted areas will be provided. Disseminating the results of the projects will be done through the organization of summer schools, workshops and conferences towards large public from universities, engineering schools and stakeholders involved in the three selected energy areas and beyond. Another outreach of the project will be the proposal for a roadmap on the technological aspects (research, industry, implementation) of the PV, CSP and grid area as well as on the best practice for the continuation of strong collaboration between the EU and MPCS partners and beyond for for mutual interest and benefits.

The main objective of the project is to develop solutions to recover the waste heat produced in energetic intensive processes of industrial sectors such as cement, glass, steelmaking and petrochemical and transform it into useful energy. These solutions will be designed after an evaluation of the energetic situation of these four industries and will deal with the development of Waste Heat Recovery Systems (WHRS) based on the Organic Rankine Cycle (ORC) technology. This technology is able to recover and transform the thermal energy of the flue gases of EII into electric power for internal or external use. Furthermore, a WHRS will be developed and tested to recover and transform the thermal energy of the flue gases of EII into mechanical energy for internal use (compressors). In order to reach this objective several challenging innovative aspects will have to be approached by the consortium. It is planned to design and develop a multisectorial direct heat exchanger to transfer heat directly from the flue gases to the organic fluid of the ORC system and to develop new heat conductor and anticorrosive materials to be used in parts of the heat exchanger in contact with the flue gases. These aspects will be completed by the design and modelling of a new integrated monitoring and control system for the addressed sectors. The consortium consists of 8 partners from 4 European countries. They cover several relevant sectors of the energy intensive industry, namely cement, steel, glass and petrochemical sectors. The industrial involvement in the project is significant and the project addresses the implementation of a full demonstration of the WHRS for electrical energy generation in one of the industrial partners (CEMENTI ROSSI) and a semi-validation of the WHRS for air compressors energy supply system at pilot scale.

A method for producing syngas from preferably vegetal biomass is described. The method provides for the use of a fixed bed gasifier, equipped with two reactors. The biomass is fed to both reactors together with a primary flow rate of air. Advantageously, the method according to the present invention is different from the known art since a secondary flow rate of air is withdrawn from the first reactor at the area where the biomass dries, and fed to the second reactor at the area where the biomass dries, and vice versa, alternately during time. Alternatively, an oscillating air flow is created in each reactor. The achievable result is a greater syngas production, but not exclusively. The syngas quality is improved too, since the biomass has a longer time for completing the gasification reactions.
