This research study analyzes the problem of waste water from the burning of palm trees which are used as fuel for power generation of palm ash. It is used to ferment biogas as a fuel for power generation where a large amount of wastewater from the gas digester is completed. The wastewater is then pumped out of the gas digester. Biological in large quantities Therefore to study the analysis of wastewater to find a method for designing a wastewater treatment system from high voltage systems from the corona discharge principle when adding ozone it is necessary to analyze the chemical effects of the wastewater according to the standard values of the Department of Industrial Works.

The objective of this research is to study the combustion behavior of a gas-saving burner S-10 using computational fluid dynamics (CFD). The simulation model was created using Fluent 6.3 in 3D-model of the same size of the burner. LPG pressure of 4 psi was released for this study. The combustion behavior was shown in temperature contour and velocity vector. The CFD results were verified by measuring the temperature around the burner head with a vessel. From the study it was found that the CFD’s results of flow velocity and combustion temperature distributions were validated with the experimental values. The CFD’s result errors were less than 10.35% and 11.87% comparing with the velocity and temperature measurement respectively. The fluid flow and combustion behaviors can be described by this CFD model. Moreover the CFD model of the gas-saving burner S-10 can be applied to improve the thermal efficiency of the burner in the future.

The objective of this research is to study the combustion characteristic of a low-pressure vertical port burner using computational fluid dynamics (CFD). The simulation model was created using Fluent 6.3 in 3D-model of the same size of the burner. The CFD results were verified by measuring the temperature around the burner head and a vessel. Moreover the results of conventional vertical port burner having the swirl angle of 90o and the inclination angle of 90o (CB-S90I90) and two swirl port burners (SB) being SB-S90I13 and SB-S30I90 were compared. The temperatures obtained from CFD and experiments were similar which the error was less than 9%. From the CFD’s results the temperature and heat flux of the SB-S90I13 burner were higher than those of the CB-S90I90 burner. The maximum temperature and heat flux of SB-S90I13 burner were 1445 K and 5291 W/m2 respectively. It was implied that the combustion characteristic and heat transfer to the vessel of SB-S90I13 burner was better than that of CB-S90I90 burner. It was resulted that the thermal efficiency of SB-S90I13 burner was better than that of CB-S90I90 burner which was the percentage energy saving of 6.93%.

The objective of this research is to study the suitable factor level for the improvement of annealing furnace for rolled coils steel sheet. The experimenting has been performed to find suitable oxygen level by 5 annealing furnace experiment. The research has been started by collection the combustion. After that the burning adjustment by changing combustion technology with 5 levels of BGCV control valve open as 23% 40% 50% 75% and 100% has been implemented. The combustion adjustment data are recorded analyzed and compared with incomplete combustion value. The research result has been found that after improvement the combustion value. The percentage of oxygen level are improved to the better quality which standard at MV0-49% equal 2.5-4 O2% and MV50-100% equal 1.5-2.5 O2% conclusion 1 furnace as follows at the MV23.1% MV40% MV50% MV75% and MV100% level of oxygen as 2.5% 3% 3% 2% 1.5% and level of carbon monoxide as 0 ppm 2 ppm 2 ppm 2 ppm and 0 ppm respectively. Resulting of fuel energy consumption in the annealing process has been reduced around 225608 baht /year/furnace. Therefore it can depict that energy saving and annealing furnace efficiency improving are increased. The modified parameters will be applied to be the new standard reference values for the further engineer’s operational manual.

The results of the study on the optimum temperature for baking soda extinguishers were investigated. B9R-3-EMERALD Using brass material in experiments. It was found that the temperature of 750˚C was good for 48% of the workpiece 52% was found that the workpiece was damaged at the surface of the work very porous at the surface. Caused by the heat of metal water pouring into contact with the moisture of the mold resulting in gas. High temperature of metal water Or eliminate gas in metal water is not exhausted. The workpiece is not suitable at a temperature of 800 ° C with a good workpiece of 76%. The workpiece loses 24%. The workpiece loses less punch at the lower porosity as well at 750˚C in temperature. 850˚C workpiece 96% workpiece 4% workpiece the workpiece is almost out. It is less than 750˚C and 800˚C at porosity. And at 900˚C the workpiece is 100% of the workpiece 0%. The workpiece is the best. Workpiece waste from the minimum. The test results make the temperature at 900 ° C is the cleanest casing temperature
