In the current work characterization of thermal properties are find out to the prepared specimens of silicon filler hybrid composite materials (silicon filler glass – fiber chop strand). The specimens were prepared by hand layup followed by compression molding machine by non-heating molding technique. Thermal conductivity (K), Coefficient thermal expansion (CTE) and Thermal gravimetric analysis (TGA) are found by composite slab method and by thermal muffler oven in a laboratory. The guard heater is used to supply heat which is measured by voltmeter and ammeter. Thermocouples are placed between the interface of the copper plates and the specimen of silicon filled hybrid polymer composite material (HPC), to read the temperatures. By the experimental readings it is found that the K of silicon filler hybrid composite material directly proportional to the % of silicon fillers for the different trails. The CTE inversely varies with % of silicon fillers and in thermal gravimetric analysis the failure of material takes place at 300°C for a time of 20 minutes and also reduction in mass of silicon inserted hybrid composite material. From the results it has been concluded that the considerable enhance in thermal conductivity with negligible decrease in CTE and increase in thermal resistivity of hybrid composite materials.

A thermodynamic study of a 20.70-MW bagasse-based cogeneration plant in the Indian sugar industry located in Belgaum is presented in this article. Analyses based on fi rst and second laws of thermodynamics using actual operating data are presented fi rst to acquaint the reader with plant's components and operation. The primary fuel energy savings achieved by the cogeneration plant in comparison with that of separate generation plants is determined and discussed. Secondly using the combustion, fl ue gas and environmental data from the plant, an irreversibility study is outlined that estimates the loss of exergy in the plant's components. The component contributing most to the overall plant ineffi ciency is pinpointed. The results show that the plant's cycle performs with an energy utilization factor of 69% and exergetic effi ciency of 28%. Because of the inherent nature of combustion irreversibility, the largest fuel exergy loss (about 70%) is noticed in the boiler.
