Improvement of Energy Efficiency and Effectiveness of Cooking for Parabolic‐Type Solar Cooker Used with Activated‐Carbon‐Coated Aluminium Cooking Pot

Abstract

In India, due to the high price of cooking gases, people still cook with noncommercial fuels like kerosene and firewood. These cause a lot of health problems and also harm the environment. A clean solution to this problem is to use a solar cooker. A solar cooker suffers from the problem of low utility and hence takes a longer period of time for cooking. To counter this problem and reduce cooking time, the solar cooker is tested with charcoal coated utensil. In this paper, a parabolic‐type domestic solar cooker is tested for the same utensil with and without cost effective thermal coating. It is observed that the effectiveness and efficiency of cooking is considerably increased by using the charcoal coating on the utensil. Considering the economic condition of the people of the selected area, this method provides a cost effective way to increase the cooking effectiveness of the solar cooker and reduce dependency on noncommercial fuels.

A review of solar, electric and hybrid cookstoves

“…Further, a concentration ratio greater than 20 and an aluminium vessel with black coating were favourable. Goswami et al [42] observed faster heating with charcoal (activated carbon) coated aluminium vessels. The highest temperature was attained in 60 min compared to 195 min with the uncoated vessel.…”

Statistical estimation of hourly diffuse radiation intensity of Budapest City

“…Diffuse radiation is considered an essential component of solar radiation that could affect the performance of solar energy systems that utilizes the beam radiation components only such as concentrated solar systems, 32‐34 especially for countries with medium radiation intensity like Budapest 35 . Various number of studies in the literature discussed in details diffuse radiation using different categories like diffuse fraction, diffuse coefficient, and clearance index to obtain a good description of the diffuse radiation.…”
