“…Three thermocouple plugs with datalogger (multi-channel temperature meter) have been used to measure the temperatures during the experiment. First plug is in front of the glass sheet sample at (x/L=0.28), second plug is in next to glass sheet at (x/L=0.675), and the third plug is behind it at (x/L=0.7) according to studies by Darweesh et al, [26] and Abbas and Muhsin [27].…”

“…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].…”

“…Increase in embracing of liquefied petroleum gas has resulted in development of different design of burner heads used in LPG glass furnaces in the industry and cook stoves. Laboratory analysis by Darweesh et al, [26], Abbas & Mushin [27], Durox et al, [28], Dhaher et al, [29], Saleh et al, [30], Santosa et al, [31], and Abulqasim et al, [32] were investigated on 16 conventional difference LPG burner heads to develop the emission inventories for LPG cook stoves and the study data used to calculate the effects of LPG cook stoves on air quality in the enclosed environment. 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.…”

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.

“…In some deterioration types, there is almost no noticeable change or reduction of weight, nevertheless characteristics change and the material could probably unexpectedly fail as a result of some changes in the material. These changes may resist visual ordinary examination or determinations of weight change [47][48][49][50][51][52].…”

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.
