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: In the present study the molten hot metal at the fluid state as well as nano fluid of CuO-water combination respectively have been transported through a 3-D rectangular open channel that has to be explored numerically. The governing Laminar Navier-Stokes equation as well as nano fluid flow equations have been solved along with the solution of the energy equation respectively. The detail heat transfer analysis along with the determination of the pressure and velocity field as well as heat transfer coefficient and friction factor etc. will be the major investigations. The pressure and....

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....
