(23) i) Determination of Water Boiling Test (Wbt ) The PDSC performance can be analyzed using water boiling test method recommended by the Provisional International Standard for Comparison [42] The methods include: Water Boiling Test (WBT): it is a laboratory test that allows the researcher to be able to know the magnitude of heat utilized, thus: (24) (25) where, M w is the mass of the water, M p is the mass of the pot, T f and To is the change in temperature, M V is the mass of water evaporated, L V latent heat of vaporization of water, C W is specific heat capacity of water; C P is specific heat capacity of pot, A is the area of the collector, Q is the radiation intensity, T is the duration. j) Evaluation of Steam Generation Test The performance of solar steam generating system can be evaluated by installing the necessary instrument to measure the required process parameters [43&44] suggested that, the collector field efficiency ƞ field can be computed using the equation below; (26) Where, m is the collector fluid flow rate (kg/s), C p is the collector fluid specific heat capacity (kJ/kg/ 0 C), T 0 -T i is the outlet and the inlet temperature ( 0 C), I is the direct solar insulation, Ac is the effective area of collector field (m 2 ) k) Experimental procedure or Test The components; the parabolic dish, receiver/heat exchanger and the support would be coupled together to form the Parabolic Dish Solar Concentrator System (PDSC). the performance evaluation of the PDSC system, experiments would be conducted for a given period of time on the performance of the receiver for steam generation and as well as for thermal applications (cooking application). The following parameters would be taken into account for the performance evaluation. First the availability of solar irradiation: this is measured using pyranometer instrument. Also ambient condition information like ambient temperature, ambient pressure/relative humidity, wind speed and its S/N PARAMETER MEASURED INSTRUMENT USED 01 Solar insolation Pyranometer 02 Wind speed Anemometer 03 Relative density Maximum and minimum 04 Ambient & content temp Digital Data logger 05 Weight of water and other food substance Electronic Weighing balance direction are essential for the performance calculation of PDSC. Table 4.1 indicates the various parameters measured using the different relevant instruments. Below is a table showing the list of the apparatus used in recording the measurements taken during the experiment. C onclusions and S uggestion To analyse the potential of the parabolic solar concentrating system, the following experimental test facilities would be developed, as schematically presented in Fig.4. Therefore, through these testing facilities, experimental tests would be carried out in order to evaluate the response and the efficiency of the system. E xpected R esults and A nalysis The main expected results from this research work is to come up with improved and efficient system that can produce a higher temperature that is required for power steam generation use for domestic consumption.
