Design and Performance Analysis of Spiral Solar Water Heater Using Iron Plate/Sand Absorber for Domestic Use

The study included the use of biofuel to reduce the percentage of environmental pollution caused by other environmentally polluting fuels that used in other studies. The current study presents investigations of CI engine performance and emissions at various engine speeds under constant engine load. The fuel under consideration in this work is biodiesel B30. A 2.4-liter, 16-valve, 4-cylinder engine with a compression ratio of 15.5:1 is used. Various inlet air temperatures (10 to 35°C with an increment of 5 degrees) are chosen to study their effects on engine performance and emissions. The results show that increasing the inlet air temperature increases brake explicit fuel feasting (BEFF) beside to nitrogen oxide (NOx), while decreasing the brake power and torque. In this scientific revision, a tentative analysis was conducted on a CI engine at various engine speeds and inlet air temperatures., The results were obtained at engine speeds of 2100 rpm at various engine loads and revealed an increase in BSFC of biodiesel blends (B20, B50, and B100) as injection pressure was increased.

“…The experimental study determined that selecting the right material of manufacture for burner is important for moderating air pollutants from combustion of LPG and enhance air quality greatly. They found that the burners made of cast iron and brass have emission indices which satisfactory standard limit by International Organization for Standardization and other regulations [33][34][35][36][37][38][39][40].…”

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.

“…But the process of erosion occurs due to chemical or physical forces [22][23][24][25][26][27]; for example, the erosion of rocks occurs due to rainwater falling on them. In short, the erosion process may occur as part of the erosion process but the erosion process cannot occur as a result of the erosion [28][29][30][31][32] as appearance in Figure 1.…”

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.
