Abstract: Different methods are used for the heat energy desired to be obtained from large-scale furnaces used in industry. Our study includes the analysis of petroleum coke and natural gas data used in the firing of large-scale rotary kilns. After firing, the temperature must rise to 1800 0C in order to sinter the material in the kiln. Therefore, two fuel type hybrids are used for the desired energy. Rotary kilns are fired with natural gas fuel since it is easier to control. Then, petroleum coke is used to increase the temperature and perform the sintering process. Rotary kilns can have certain lengths according to the material to be sintered. After this process, the waste heat goes to the boiler.....

Abstract: A significant challenge in air-conditioning installation is the precise calculation of the cooling load—the total heat that needs to be extracted from a space for effective cooling. Traditional methods for these calculations are either laborious manual computations or unreliable estimations based on simplistic rules of thumb, which can lead to inaccuracies in equipment sizing due to the complex nature of modern architectural designs. Most existing cooling load calculation software target HVAC professionals and are often expensive and impractical for wider usage in developing....

Abstract: SuperNi 276 is widely recognized for its outstanding corrosion resistance and high-temperature performance, making it an essential material in the aerospace and power generation sectors. However, fabricating precise micro-holes in this alloy presents challenges with conventional machining methods. This study investigates the application of Electro Discharge Drilling (EDD) to produce high-quality micro-holes in SuperNi 276. By varying input parameters such as pulse on time, pulse off time, and peak current—using tool diameters of 0.5 mm, 0.6 mm, 0.7 mm, and 0.8 mm while maintaining a constant voltage of 2V—key output parameters, including Tool Wear Rate (TWR) and Material Removal Rate (MRR), were evaluated.....
