“…These swirls enhance the mixing rate of the fuel and air that used in the combustion procedure, which increases the energy produced and decreases emissions. The combustion procedure by this technology has a more stable range of blowoff and flashback levels, high levels of turbulent flame speed and low burning volumes by using these technique of flow [47][48][49].…”

“…Bending the glass progress with time and increase temperature. The cooling process [46][47][48][49] is in the same furnace and it is also gradually with the time to avoid deformation in the glass model, where the burner is extinguished and left the furnace is closed until the temperature is reduced naturally within it [50][51][52].…”

The extant research design LPG give a good temperature distribution for a specific burner design of low consumption burners and relays to a method for bending the glass sheets, in which method the swirl burner LPG is used in a small furnace. Using LPG fuel gives more stability in the combustion process, the LPG is a gaseous fuel that helps to have easy control of the combustion rate and the temperature behavior inside the combustion zone by increasing and decreasing the mixing ratio with air. The heat flux from the flame moves in the front direction due to the momentum of the fuel mixture and the design of the burner rim, which keep the flow adhesive, such behavior leads to creating different temperature zone since the combustion process is a continuous process. The main result is that clean or low emission combustion of LPG fuel will increase the gained temperature and give a good temperature distribution for a specific burner design of low consumption burners and the clean combustion will reduce the unwanted deformation of soot on melting glass surface. Generally, high energy cost and the environmental pollution are the major issues in the glass industries which must be reduced through reduce the fuel consumption of the glass furnaces. For these reasons, this type of furnace can be used in other applications, not only in melting glass.

“…The increasing of inhibition efficiency with concentration conceals that extra inhibitor particles are being adsorbed at higher attention on the metal surface, affecting larger surface coverage. A deterioration inhibitor is simply a substance that is smeared to environment to significantly reduction the corrosion rate in especially metals in special and materials that are in exposure to that environment [40][41][42][43][44][45][46]. It is labeled the first defense line against deterioration.…”

Thermal deterioration of Machines is the change in the properties of the basic material as a result of thermal reaction with its environment as a result of the presence of moisture in the bodies of machines such as the bodies of aircraft, cars, engineering equipment and related to the mechanics of the machines in the field of mechanical engineering, which is called the medium of deterioration and not as a result of a mechanical process such as friction in the machines as a result of work Continuous in these machines, according to this definition there is a possibility of corrosion not only in metals, but other materials such as concrete and containers that are in direct contact with moisture, air and environmental factors that are a catalyst for mechanical deterioration. Many researchers in mechanical engineering were interested in the thermal processes of machines, so the problem of corrosion and friction of machines and other important problems that have been studied extensively by finding engineering solutions to reduce or eliminate them. Corrosion of Machines be a limiting factor for various materials in many applications. Thus, it is necessary to have a better understanding of the deterioration processes, their prevention and reduction of the associated damage. In this research the preparation of some reagents and their use as deterioration inhibitors to reduce the deterioration process in engineering machinery by measuring the loss in weights resulting from the phenomenon of deterioration in engineering machinery. These thermal reagents were prepared as a thermal inhibitor painting, diagnosed in spectroscopic techniques, and then some thermal measurements were made to studying them as inhibitors of engineering corrosion in machines. The results appeared that the prepared reagents are good deterioration’s inhibitors due to the inhibition efficiency of the selected thermal reagents increased with increasing of concentration, and decreased with increasing of temperature.

“…Moreover, when calculating the absorption power, it is assumed that the PV cell absorbs the entire incoming heat flux because the only type of heat loss from the panels is stationary convection loss. Hence, the three governing equations in this research are the mass Equation 1, momentum Equation 2, and energy Equation 3 [36].…”

Extensive research has been conducted to address the issue of the reduced efficiency of solar photovoltaic (PV) cells at high temperatures. To address this problem, a hybrid cooling system has been developed. This system uses a thermal collector to convert waste heat into reusable heat. Selecting the best configuration and operational parameters for the collector is crucial for maximizing system performance. To achieve this, we conducted computational fluid dynamics (CFD) modeling using ANSYS. Various factors affecting the cooling of PV solar cells were analyzed, including the collector design, mass flow rate, and concentration of the Al2O3 nanofluids. Results showed that the 12S finned thermal collector system exhibits the lowest temperature for PV solar cells, at approximately 29.654 oC. The electrical efficiency of PV solar cells is influenced by the concentration of Al2O3 nanofluids. We found that the 12S finned collector system with 1% water/Al2O3 nanofluid achieved the highest efficiency (approximately 11.749%) at a flow rate of 0.09 kg/s. The addition of finned collectors affects efficiency and variations in fluid mass flow rates, and there is no relation between the connector type and different Al2O3nanofluid concentrations. In other words, the cooling system can be optimized to enhance the efficiency of the PV solar cells under high-temperature conditions. Doi: 10.28991/CEJ-2023-09-12-03 Full Text: PDF
