Paper Details

The solar energy has the greatest potential of all the sources of renewable energy. To use the solar energy,solar collectors are integral part. Different types such as flat plate collector, evacuated tube type collector, parabolictrough collector and dish type collectors are used. Larger space requirement and less thermal efficiency are the problemwith the present solar collectors systems. These problems can be handled with the new idea of solar collector. In thepresent study, the innovative and novel design of the solar collector, known as Rotating Solar Boiler is discussed. Therotating solar boiler is nothing but the modified parabolic trough solar collector in which the absorber is larger in sizeand rotating with certain speed. It’s construction, working principle, thermal analysis, heat losses, performance study tounderstand and to make comparison with other existing solar collectors are given in the paper. The detail and extensivedesign of the device was done. As per design, system was manufactured for experimental investigation. The device wastested for different speeds i.e. stationary, 40 rpm, 60 rpm, 80 rpmand 100 rpm to check its performance. Experimentalresults are studied to determine the optimum speed for Rotating Solar Boiler. Calculated efficiency of device is comparedwith stationary parabolic trough collector. It was found that rotating solar boiler is performing with higher efficiencywhen it is rotating with 80 rpm. This efficiency is more by 9 % to 15 % than that of stationary collector. Area of RotatingBoiler is also less by 20% in comparison with conventional flat plate collector and trough collector. In winter season, themaximum temperature of water obtained in device is around 53oC at 450 – 500 W/m2solar radiation which is greaterthan 8 oC compare to flat plate collector. This high temperature water can be used for any industrial as well as domesticpurpose. Therefore present study is ended with conclusion that the rotating solar boiler may be contributed in the futureof solar energy application considerably
