This research aim to improve a combustion system of boiler within increase combustion efficiency and use all out of the energy. The large boilers were used in the industrial factories which consume a lot of energy for production. By oil and gas fuel will be increasing costs everyday cause many factories interested in energy saving with any method technical engineering specifically for production costs and environment effect decreasing. This researching was installed and program was invented in the industrial factory. This industry factory consumed cogeneration energy for fabric dying. The efficiency before installing the software is measured about 65.85 - 71.98% which heat in exhaust gas about 20% of overall energy is filled in the system. After installing heat loss in the system has been fallen until remain about 5 - 12% and efficiency of heat in system has been reached a peak of 80 - 85%.

Now a day the mostly air condition are use vapor compression refrigeration system in which R-22 refrigerant is used as a working substance. From the results of study it found that the quantity of water vapor or moisture in the air is condensed with in the fan coil unit while through out the evaporator. The fluid after condense is called condensed water. By this process the quantity of condensed water is increases when the air condition is used in the long time. To increase the utility the condensed water is recovered for the heart reduction in the finned-tube condenser. The experiment is consist of two conditions by using the air and condensed water to heart reduction. But in case of condensed water the pressure operation is controlled at 280 and 260 Psig respectively. The results of experiment shown the refrigeration effect coefficient of performance (C.O.P) and energy efficiency ratio (EER) is 39675 Btu/hr 3.01 and 10.3 Btu/hr.Watt respectively with the air is used. At the pressure operation 280 Psig refrigeration effect (C.O.P) and (EER) is 44212 Btu/hr 3.38 and 11.5 Btu/hr.Watt respectively and 49856 Btu/hr 3.99 and 13.6 Btu/hr.Watt at pressure operation 260 Psig. Furthermore the capacity of condenser is increases to 11.43% and 25.6% and also the refrigerant efficient is increases to 12.43% and 32.43% at the pressure operation 280 and 260 Psig. Thus the parameter of the energy efficiency ratio depends on the capacity of condenser working substance temperature (pressure operation) and air surrounding temperature.

This research aimed to improve combustion burning system of boiler and to increase burning efficiency and use all out of the energy. The large boilers were used in the industrial factories which consume a lot of energy for production. The Increasing oil and gas fuel costs everyday cause many factories interested in energy saving with any technical engineering methods specifically for production costs and environment effect decreasing. This research program software was installed and invented for the industrial factory. This industry factory consumed cogeneration energy for fabric dying. The efficiency before installing the software is measured about 65.85-71.98% and heat loss by 50% of overall energy in the system. After installing heat loss in the system has been fallen to 5-12% and efficiency of heat in system has been reached a peak of 80-85%.

The attempt to fabricate gold films on glass slide (Au/glass) and silicon wafer (Au/Si) with gold leaf was unsuccessful due to poor adhesion between the gold leaf and substrates. Alternatively Au/glass and Au/Si films were fabricated by placing the substrate into the free space within sputtering chamber to collect the access Au vapor during the typical sputtering process for other samples. In this study the physical changes were observed in both Au/glass and Au/Si film under the film annealing from 300⁰C-700⁰C. The visual inspection via cell phone camera the micrograph via Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) revealed the morphological changes with respect the annealing temperature in Au films due to solid state dewetting mechanism. The changes were more pronounce in Au/glass films than Au/Si films at the same annealing temperature. The X-ray diffraction measurement three phases of Au including Au(111) Au(200) and Au(220) in Au/glass films and one phase of Au(111) in Au/silicon films. The concentration and single crystallinity of Au(111) were increased with respect to annealing temperature in Au/glass film. For Au/Si films the concentration and single crystallinity of Au(111) were decreased at 300⁰C and then were increased at 700⁰C respectively. The physical changes of Au films are likely due to the movement of Au atoms via solid state dewetting and recrystallization. The heat intake from annealing process is likely induced the dewetting process by increasing the kinetic energy of Au atoms. While the recrystallization process is likely occur during the cooling period of the samples. Finally another factor that can affects the physical changes of Au films is the interface interaction between Au films and substrates.

This research is to develop and experiment the hybrid solar dryer by using cultivated banana as the ingredient in the experiment. The objective is to design create and test the hybrid solar dryer that using heat energy with infrared heater. The result from the experiment of drying cultivated banana at night-time by using heat energy from infrared heater is found that at night-time experiment cultivated bananas moisture is decrease more than at day-times experiment for 61.25 %. The temperature inside the hybrid solar dryer at night when using heat energy from infrared heater is at 49.1-55.0°C. Using heat from sunlight together with infrared heater cause the cultivated bananas moisture to decrease better approximately 27 % when compare to drying with heat energy by only sunlight.
