DESIGN AND CONSTRUCTION OF A CONCENTRATOR TYPE SOLAR COOKER

Abstract

ABSTRACT A concentrator type solar cooker has been designed and constructed. The concentrator is made up of two concentrating systems: a spherical dish and a reflector field. The spherical dish consisted of segmented plane mirrors while the reflector field consisted of an array of plane mirrors mounted on individual stands. The data were collected at the observatory of the Department of Meteorology, Federal University of Technology, Akure (7. ISDN, 5.050E). Data collected include, water temperature (the content of the pot), air temperature; wind speed and insolation. The time interval for data collection was 1 minute. The average is taken for 10 minutes, this was done by a logger. But that of water temperature was done manually at an interval of five minutes, and the average taken over 10 minutes. The power of the cooker was found by multiplying the mass of water by temperature gain within the 10 minutes interval and dividing by 600 seconds, The results of the test Was 72.5 percent satisfactory.
