AbstractAbstract
[en] As a part of the project 'development of hydrogen production technologies by high temperature electrolysis using very high temperature reactor', we have developed an electrolyzer model for high temperature steam electrolysis (HTSE) system and carried out some preliminary estimations on the effects of heat recovery on the HTSE hydrogen production system. To produce massive hydrogen by using nuclear energy, the HTSE process is one of the promising technologies with sulfur-iodine and hybrid sulfur process. The HTSE produces hydrogen through electrochemical reaction within the solid oxide electrolysis cell (SOEC), which is a reverse reaction of solid oxide fuel cell (SOFC). The HTSE system generally operates in the temperature range of 700∼900 .deg. C. Advantages of HTSE hydrogen production are (a) clean hydrogen production from water without carbon oxide emission, (b) synergy effect due to using the current SOFC technology and (c) higher thermal efficiency of system when it is coupled nuclear reactor. Since the HTSE system operates over 700 .deg. C, the use of heat recovery is an important consideration for higher efficiency. In this paper, four different heat recovery configurations for the HTSE system have been investigated and estimated

AbstractAbstract
[en] The thermal process of wastes with higher calorific value by pyrolysis is reviewed to recover the value added three by-products; a pyrolytic char, a pyrolytic oil, and a non-condensable gas. These by-products from pyrolysis of the waste is converted for electricity power and thermal energy thru gasification process as well as waste heat recovery process. The energy resource and several processes in the integrated pyrolysis gasification combined cycle for waste treatment are investigated with the conceptual design in using the obtained operation data from the pyrolysis pilot, demonstration and commercial plant.

AbstractAbstract
[en] This paper describes the 'crud' measurements performed during the Embalse nuclear power plant's thermal cycle for a power of 100% (645 MWe) under different purification conditions. The aim of this work is to optimize the four steam generators' tube plate cleaning in function of the sweeping produced by their purification. (Author)

AbstractAbstract
[en] For three sites located in Burundi, Madagascar and Rwanda which have been selected after a previous study, this document reports a feasibility study and the definition of the characteristics of micro geothermal plants which could be installed there. These plants convert thermodynamic energy into mechanical and electric energy, with a recoverable power of 15 kWe. After a description of the operation of such micro-plants (principle, hot water and cold water circuits, exchangers, engine, freon circuit, electric power production, regulation and automatism), and a description of the selected sites (location, physical and chemical characteristics), a pre-sizing is reported (fluid selection, needed water flow rates, components). The report discusses the use of the produced electric power, and reports an assessment of construction costs (site development, plant construction and installation), discusses the exploitation and installation of the plant. Results are globally discussed in terms of thermal and cold water flow rates, of possible electric power, and of chemistry of underground waters. If the operation appears to be technically feasible, the cost appears to be high due to the characteristics of the thermal water temperature

AbstractAbstract
[en] One of the most popular and feasible strategies to reduce costs for electrical and other energy supply in remote communities is the development of wind-diesel systems. In these systems, a significant share of the electrical energy requirements of a community can be provided by wind turbines connected to the community electrical distribution system. One of the characteristics of the systems having a relatively large ratio of wind turbine capacity to community load, called High Penetration Wind-Diesel Systems (HPWDS), is that during high wind periods there will be electrical energy available in excess of the net load on the system. An important concept of the HPWDS strategy is that this excess energy can be directed to a practical use, such as heating. The concept of HPWDS was shown to be economically and technically feasible in communities having no heat recovery on the diesel plants. It proved to be even more attractive as a strategy for self sufficiency of electrical supply in communities with waste heat recovery. 1 fig., 1 tab

AbstractAbstract
[en] Small gas turbines in power range of several MWs are quite suitable for application in distributed generation as well as Community Energy Systems (CES). Humidification is an effective way to improve gas turbine performance, and steam injection is the most general and practically feasible method. This study intended to examine the effect of steam injection on the performance of several MW class gas turbines. A primary concern is given to the regenerative cycle gas turbine. The steam injection effect on the performance of a system without the regenerator (i.e. a simple cycle) is also examined. In addition, the influence of bypass of some of the exhaust gas on the performance of the gas turbine, especially the regenerative cycle gas turbine, is evaluated.

AbstractAbstract
[en] This study addresses the funding of heat recovery projects, and aims at identifying brakes to be lifted in order to improve project valorisation, at identifying all risks to be covered during the financial arrangement, and at proposing the most relevant tools to do so. It focused on heat recovery in industrial sites and in waste elimination sites for a purpose of internal or external heat valorisation. It proposes an overview of projects of valorisation of industrial recovery heat (definition, key activities and actors, identification of four main project types, definition of project structure phases and of associated activities), proposes a methodology of project analysis applied to heat recovery (components related to investment decision, funding modes), identifies risks (risk definition, risk assessment, identification of main risks), proposes an overview of the main deadlock points noticed in existing projects, briefly describes solutions which are implemented in the world or in other activity sectors. Then, it reports a synthetic analysis of existing and mobilizable funding tools, and reports an application of this analysis to three different cases. Recommendations are then stated for a higher transparency and a better analysis method, for the implementation of specific arrangements, with a focus on exceptional depreciations and on various subsidies. An appendix contains an inventory of arrangements. A synthetic version of this report is provided
