Abstract


Concentrated solar arrays likely to play an important role for the solar powered kitchen, Instead of burning natural gas in the burner to prepare the food it is better to utilize solar power to generate the same quality and temperature of steam as natural gas. Therefore, the use of solar power could reduce demand for natural gas required for cooking purpose, which can be redirected to other economic activities, such as power generation, water desalination and as feedstock and energy for industrial processes.

As by taking the example of India, The solar kitchen has been set up at Taleti, near Mount Abu, situated at a height of 1219 m above sea level in Rajasthan. It boasts of a six-module solar steam cooking system and a total of 84 parabolic dish concentrators shell type receivers. Each oval parabolic concentrator has a reflective surface area of 9.2 square meters, and reflect sunlight on the receivers by special white glass pieces. Steam is collected in the header pipes, which is then directed via insulated pipes to cooking vessels in the kitchen.

The system generates temperatures of up to about 650 degrees, and 3500-4000 kg of steam per day. The food is cooked in 200-400 liters capacity cooking pots, producing an average of 20,000 meals a day, and up to 38,500 meals per day during periods of peak solar radiation maximum.
