Fresnel lens panels could be used instead of clear glass to increase the amount of light gathered and then focused by the reflector onto the boiler pipe. I was also thinking about their use, incorporated as panel arrays with the glazing in a greenhouse, where their focal points would each increase the amount of solar energy hitting black

Concurrent analytical and experimental studies were carried out on linear Fresnel lens solar collectors to determine their potential for producing superheated steam. Nine tracking Northrup collectors were connected in parallel as a single pass boiler. Flat plate collectors were used to preheat the water entering the Fresnel collectors, and superheated steam was produced for all …

Oct 23, 2014 · This paper proposes a new kind of system for effective indirect solar cooking by utilizing a novel Fresnel lens. A semi-cylindrical vessel (solar boiler) for producing steam and a jacketed cooker was designed, fabricated and tested experimentally for cooking applications. The solar boiler produced high temperature steam of 146°C and pressure

The first commercial linear Fresnel reflector (LFR) system called Puerto-Errado 2 (PE 2) was completed in Spain in 2012 and built by Novatec Solar. PE 2 is a 30 MW plant with a solar boiler of 302,000 m 2 mirror surface area. The system is designed to produce approximately 50 million kWh of electricity every year being the world's largest CSP

A theoretical analysis of a series of Fresnel lens collectors which are connected in parallel for tracking the sun to produce wet steam is presented. Equations which are derived for the efficiency of the Fresnel lens-target tube absorber combination (boiler efficiency), fluid temperature distribution, and the mass fraction of fluid vaporized

Final Report | Concentrated Solar Distillation as a Means … A second parameter to be tested was the use of a secondary solar collector versus direct heating of the boiler unit by the Fresnel lens. Secondary collection would allow multiple lenses to apply solar energy to a single boiler unit.

Fresnel lens will be used to heat up the feed water to increase the temperature up to 300 degree Celsius steam before entering the boiler. High temperature feed water will enter into the boiler and increase the steam temperature to almost 500 degree Celsius. So boiler will need less fuel for combustion to reach its

Dec 06, 2009 · When I did some experiments with a fresnel lens water distiller, the lens needed to be moved fairly often to track the sun and direct enough intense sunlight to the boiler. Ambient, reflected and refracted light didn't produce much heat at the focal point and beyond.

An average of 1.6 litres of water was produced per day by the system with boiler volume 3.18 litres and rectangular Fresnel lens of size 345 x 345 mm. Heat loss from system may be further controlled by larger aperture lens and selective insulation of copper duct. Addition of baffle for heating and fins at condenser may increase heat transfer rate.

Supplementary heat or steam generation for power plants. Fresnel mirrors are being considered as a means to supplement heat in thermal power stations. Parts of the cycle such as preheating of the boiler feed water use low to medium temperature heat sources, and solar thermal systems can provide this heat.

This allows multipurpose use such as making and annealing fused glass objects, heat treating knives, and annealing glass objects made by blowing or lampworking. An alternate method for powering is to have fresnel lenses heat a boiler and run a steam engine in place of fire. Of course you can use a J-tube to heat the boiler on cloudy days.
