What is Solar Furnaces? Definition, Advantage, and Disadvantages

In this article, we will learn about What is Solar Furnaces? Definition, Advantage, and Disadvantages.

Solar furnaces

A solar furnace is a device designed to integrate solar radiation over a specimen and obtain a higher temperature. The external structure of the solar furnace is shown. It consists of a concentrator (collector), receiver, and heliostat.

A large number of heliostats (turnable mirrors) are placed on top of a sloping surface so that the solar radiation always falls on a large parabolic reflecting collector.

The collector then concentrates the radiation in a small volume receiver. Heliostats are pivoted at 15 per hour throughout the day

Rotate slowly to the level of. The maximum temperature available at the point of accumulation in the mirror is about 3800 C. Its maximum heat flux is about 16,000 kW / sq.m. Is.

Advantages

1. Can be heated without spoiling anything.
2. Gives a very high temperature.
3. The temperature can be easily controlled.
4. No damage by ions.

Disadvantages

1. Its use is only about 4-5 hours a day.
2. The starting price is high.
