Conversion of a Solar Geyser to Solar Cooker & Its Performance Evaluation

Abstract

For reducing the consequences of global warming and fuel scarcity, we need to change dilemma in terms of cooking. For resolving this issue, the solar cooking offers the best alternative. There are various designs of solar cookers. Different types of solar cookers are presented by a number of researchers over the decade that includes the box type solar cookers and parabolic type solar cookers. However, these types of solar cookers have limited performance in terms of tracking and operating during night time. An evacuated tube solar geyser is converted into a solar cooker which is obsolete from tracking and cooking can also carried out during night time having a thermal storage unit (TSU). The performance of the system is observed during clear days and nights of August and September 2019 in Peshawar, Pakistan. The maximum temperature attained by the system is recorded 98.5 o C. From the observed experimented data, the results indicate that the system is faithfully performing under the required climate conditions.
