Performance evaluation of parabolic dish type solar collector for industrial heating application
From Indian perspective there is a large potential available for low cost solar water heating systems. The described system can instantly fulfil needs of hot water in industrial sector. This type of system can be used for heating boiler feed water, laundry applications and other steam generation applications. In general, concentrated solar collectors have high efficiency as compared to flat plate ...

Flat absorbers with trapezoidal cavity for Fresnel reflecting solar concentrator
The absorber is a very important component of the solar concentrating collector. The overall heat loss coefficient of the flat rectangular absorber and multi-tube absorber were studied experimentally. Both absorbers were coated with ordinary dull black paint. The heat loss coefficient was comparatively 4-11% lower in the case of round pipe absorber and increased with the absorber temperature in ...

Advanced Solar Thermal Technologies for Clean Water
Artic Solar proposes to integrate a high temperature solar thermal collector and a proprietary steam generator to provide the steam and the required energy for a solar thermal distillation or evaporation system. The ability to generate steam on a continuous basis using water for the heat transfer fluid in the collector closed loop increases efficiency and lowers the cost of energy required for ...

Alternative scenarios of the utilisation of renewable energy sources in small prefectures: a case study in Lasithi Prefecture, Greece
The sector of Renewable Energy Sources (RESs) is growing very fast, with many innovations and applications becoming a reality. The continuous reduction of natural resources has forced all policymakers to turn to alternative energy sources. The total energy (oil and electricity consumption) consumed in the prefecture of Lasithi during the years 1997?2002 in correlation with the RES exploitation ...

A new type of solar concentrator employing a cone-cylinder combination
Most conventional solar thermal radiation concentrators have some sort of symmetry which allows them to concentrate solar thermal energy for their operation. We report a new system that utilises the symmetry of a cone and a cylinder combination to simulate the concentration of solar radiation on a ring containing a fluid (water). A halogen lamp is used as the source of radiation to simulate solar ...

Heating Water to Create Steam with Solar Power - The XCPC Solar Thermal Solution
Achieves temperatures in excess of 200 Degrees C at more than 50% efficiency (the percentage of incident solar radiation converted to useful heat energy) which current market incumbents cannot approach without tracking. Maintains efficiency even at high operating temperatures. Flat plate and other evacuated tube collectors exhibit good efficiency at lower temperatures but heat losses mean that ...

On rooftops worldwide, a solar water heating revolution
The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors to convert sunlight into heat that can be used to warm ...
