Boiler Heating With Fresnel Lenses


Giant Fresnel Lens Deathray: an Experiment in Optics : 12

A solid glass lens that size would be silly, but instead we can use a 4 foot wide Fresnel lens. You know, those clear, flat things with the ridges, you find them on overhead projectors and rear windows on some buses? The idea is pretty simple: a Fresnel lens is just a normal curved lens chopped into thousands of little rings, but just as effective.

Superheated steam generation in a Fresnel lens

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 cases.

Study of Performance of Fresnel Lens Solar Concentrator

The demand for process heat particularly low pressure steam is increasing in recent past. Solar energy can be utilized for generating medium temperature (100°C -150°C) low pressure (T<200°C) steam. By using solar concentrators, low pressure steam can be generated by using low cost technology [1]. Fresnel lens solar concentrators are very useful to generate low pressure steam for industrial
