Abstract
In this study, a hybrid diesel generator plant system was designed and tested with the help of heat supplied by a parabolic-linear solar collector. This system was defined according to the availability of the solar collector power plant system in order to increase its capacity by using clean and clean fuel production. Also, in order to increase the heat transfer efficiency in the solar collector system, nanoparticles were used in the base fluid. Copper oxide nanoparticles and magnesium oxide have been investigated due to the high thermal conductivity coefficient. Base water and ethylene glycol fluid were also tested individually and the effect of adding nanoparticles on their heat transfer capacity was reported. Each nanoparticle with volume percentages of 0.15%, 0.25% and 0.35% was tested. The results of using nanoparticles in different volumetric percentages indicated that by increasing the volume percentage of nanoparticles inside the fluid carrier, the heat transfer capacity as well as the fluid density coefficient increase and this has led to an increase in the temperature of the outlet from the collector and the entrance to the bio diesel engine reactor. A temperature control system based on fluid flow control was obtained using the transformation functions of each component and the formation of closed circuit loop diagrams. Due to the different outlet temperatures at the output of the solar collector system, different experiments were carried out to produce fuel from rapeseed oil and the results were analyzed. Then, with the optimal conditions for the design temperature of the diesel fuel hybrid system design, it was based on the design of a fluid flow control system in the diesel engine reactor to control the reactor temperature. Bio diesel in this design is produced by using a stear exchange reaction in the presence of a sodium hydroxide catalyst. The diesel fuel produced by using chlorine plant oil was isolated after the production inside the reactor, and the relevant tests and analyzes were performed to ensure the percentage of conversion of oil to fuel as well as the specifications of the fuel produced. The results showed that the percentage of oil-to-fuel conversion in this method was 91.4%, which is acceptable.
