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.

“…Organic Rankine cycles (ORC) operate from low-temperature heat sources are commonly used for power generation. The available energy resources are solar energy, wind, biomass products, geothermal energy, surface seawater, and others, including waste heat from various thermal processes [13][14][15][16][17]. For temperature below 200 o C, Isobutene is a common working fluid, while toluene is often used at higher source temperatures.…”

“…As their oil production is far higher than that of terrestrial plants, biofuels from microalgae feedstock have been shown to be potential feedstock for future organic working fluids. Microalgae feedstock does not compete with food supplies and does not require high quality agricultural land; the supply is available continuously, it is able to grow under hasher condition, it is non-edible, and it shows highly genetically modifiable nature and fast growth rate when compared with conventional fuel [14][15][16][17][18]. In addition, the main advantages of using biofuels from microalgae as organic working fluids in an ORC system compared to a conventional fuel include the following: (i) it does not produce hazardous waste or pollution, (ii) it is carbon neutral, (iii) it produces highly biodegradable biofuels and less toxic, (iv) and it has a lower vapour pressure [19,21,[23][24][25][26].…”

Marine diesel engines are commonly used as a propulsion system in ships. The waste heat generated from marine diesel engines is one of the key disadvantages of this system. This study aims to improve the recovery of waste heat generation. It presents the performance analysis of Organic Rankine Cycle (ORC) for exhaust gas in a marine diesel engine using different types of biofuels production methods from selected microalgae via mathematical modelling. The microalgae are from species of Synechococcus PCC 7002, Nannochloropsis oculata sp, Chlorella protothecoides, and Dunaliella sp. A marine engine with an exhaust gas of 9086.61 kg-h-1 is taken as a case study. While the conventional diesel engine has a performance efficiency of 30-40% with a power output of 35-200K, this study has indicated that the marine diesel engine in the ORC via biofuel from algae shows higher performance at approximately 51% with a net power output of approximately 160kW obtained for each biofuel. Later, the thermal efficiency of the ORC system with exhaust gas from the marine diesel engine as waste heat recovery is improved to 61% with a net power output of approximately 353kW after the heat integration. Biodiesel presents the highest mass flow rate (1.12 kg-s-1) compared to others. This study proved that biofuel from microalgae can achieve the highest performance in the ORC system with the lowest mass flow rate of biofuel compared to those in conventional fuel.

“…Solar reflectance greater than 95% requires a thickness of 160 m. Sweat wicking and drying are hindered. A major personal thermoregulation pathway, moisture management, in hot, humid, and sunny conditions, is essential to wick sweat away from skin and evaporate it quickly so that heat can be dissipated, and the body can cool safely [20][21][22][23][24][25][26][27][28][29][30].…”
