The results of experimental studies by the performed complex of thermophysical characteristics of created polymeric microand polycarbonate-based nanocomposites, which comprise from 0.2 to 10% carbon nanotubes and microparticles of aluminum are presented. Materials on the interpretation of the data based on the percolation theory are submitted. The possibilities of using of offered composites for the production of heat exchangers, focused on low-grade heat transfer and operating in hostile environments are previewed.
We have analyzed the major activities carried out for geothermal electricity generation since WGC2010.New data has been taken from WGC2015 Country Update reports, private communications from IGA members and Affiliated Organizations, and we would like to acknowledge all IGA friends for their valuable help. Other updates have been collected from websites of private and public organizations involved in geothermal development. Plants under construction, which are expected to be commissioned in 2015, are included in the installed capacity. An increase of about 1,7 GW in the five year term 2010-2015 has been achieved (about 16%), following the rough standard linear trend of approximately 350 MW/year, with an evident increment of the average value of about 200 MW/year in the precedent
The article presents new developments, in particular, is equipment for neutralization of acid condensates of gas combustion products in heating and industrial boiler houses and a new cavitation type extractor. The article described principle of work and the results of experimental studies are presented which confirm the effectiveness to application of equipment in various industries.
В структуре энергетического баланса Украины доля импорта энергоресурсов превышает собственную их добычу и производство, что ставит страну в серьезную зависимость от импорта, несмотря на то, что Украина имеет все возможности полностью обеспечить себя энергией. Для этого необходимо повышать уровень энергоэффективности и способствовать распространению использования экологически чистых технологий возобновляемой энергетики, в частности геотермальной энергетики. Геотермальная энергетика является устоявшейся и относительно зрелой формой коммерческого использования возобновляемых источников энергии. Важной характеристикой является фактор высокой нагрузки, что означает, что каждый МВт мощности производит значительно больше электроэнергии в течение года чем МВт ветра или солнечного потенциала.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
