AbstractAbstract
[en] An economic analysis of Quebec residential electricity demand was studied by micro-simulation models. These structural models describe all components which lead to decisions upon durable holdings and electric appliance usage. The demand for space and water heating systems was evaluated. Recent price change in favour of energy sources other than electricity were taken into account. Price and income elasticity ratios were found to be low, as expected when estimating short term use. The role played by socio-economic variables on the choice of space-water heating systems and electricity use was also examined. Recent conversions have indicated a trend toward preference by households in favour of natural gas or oil over electricity. 18 refs., 5 tabs., 1 fig

AbstractAbstract
[en] Currently the market for solar heating applications in Canada is dominated by outdoor swimming pool heating, make-up air pre-heating and domestic water heating in homes, commercial and institutional buildings. All of these involve relatively small systems, except for a few air pre-heating systems on very large buildings. Together these applications make up well over 90% of the solar thermal collectors installed in Canada during 2007. These three applications, along with the recent re-emergence of large-scale concentrated solar thermal for generating electricity, also dominate the world markets. This paper examines some emerging markets for large scale solar heating applications, with a focus on the Canadian climate and market. (author)

AbstractAbstract
[en] Application of exergy analysis methodology for encapsulation of photochromic dyes by spray drying was presented. Spray drying system was investigated considering two subsystems, the heater and the dryer sections. Exergy models for each subsystem were proposed and exergy destruction rate and exergy efficiency of each subsystem and the whole system were computed. Energy and exergy efficiency of the system were calculated to be 5.28% and 3.40%, respectively. It was found that 90% of the total exergy inlet was destroyed during encapsulation by spray drying and the exergy destruction of the heater was found to be higher. (paper)

AbstractAbstract
[en] An integral part of the feedwater heater condition assessment program consists of an inspection program performed on a periodic basis to help extend the availability of feedwater heaters. If applied effectively, NDE can extend the life of feedwater heaters by eliminating insurance plugs, minimizing tube leaks, assisting where necessary with design modifications and improved water chemistry, and repairing defective tubes for safety and remedial reasons. By performing inspection on a periodic basis, more realistic, up-to-date heater conditions can be obtained for a planned and timely heater replacements. This paper presents essential components of an effective NDE program to better prepare and assist utilities with reliable feedwater heater inspections

AbstractAbstract
[en] For the 19th time the title survey has been carried among Dutch households. Total domestic natural gas consumption increased slightly each year, while the natural gas consumption per household decreased. In 1996, however, the total increase appeared to be substantially higher than previous years, while also the use of natural gas by households has increased. The figures for 1997 show a different trend: the total increase is less than 1996, and the decrease of the consumption per household is increasing. This could be caused by a growing market share of condensing boilers and the increasing insulation value of dwellings as well as statistical deviations

AbstractAbstract
[en] The invention concerns a steam generator for a nuclear plant where feed water is preheated before mixing to recirculated water. This preheating allows a better use of the exchange surface and an increase in thermal efficiency of the generator. This result is obtained by directing an important fraction of recirculated water toward the hot leg of the tube bundle, the remainder beeing mixed to the whole of feed water. This fractionation is produced by the pressure-drop created by a flange and two distribution plates with different permeabilities placed respectively in the hot leg and in the cold leg

Cette invention concerne un generateur de vapeur pour centrale nucleaire dans lequel l'eau d'alimentation est prechauffee avant son melange a l'eau de recirculation. Ce prechauffage permet une meilleure utilisation de la surface d'echange et un accroissement du rendement thermique du generateur. On obtient ce resultat en dirigeant une fraction importante de l'eau de recirculation vers la branche chaude du faisceau de tubes, le reste etant melange a la totalite de l'eau d'alimentation. Ce fractionnement est produit par la perte de charge creee par une collerette et deux plaques de distribution de permeabilite differentes placees respectivement dans la branche chaude et dans la branche froideOriginal Title
