The Life of Hedonism from the Perspective of Al-Tabari and Sayyid Muhammad Rashid Rida (Comparative Study of Tafsir Surah Ali Imran: 14)
No full textThe Qur'an not only tells us about prohibitions and commands, but also talks about the problems of the lives of previous people. Among them are illustrated by the human lifestyle that prioritizes pleasure and physical luxury. Based on the hedonistic lifestyle, it certainly has 'ibrah that can be learned if an in-depth study of the life of hedonism is carried out. The author wants to examine the life of hedonism from the perspective of al-Tabari and Sayyid Muhammad Rasyid Rida. This paper uses a qualitative approach that is classified into library research with library materials, especially Jami' al-Bayan fi Ta'wil Ayi al-Qur'an and Tafsir al-Manar and uses comparative data analysis. The conclusion in this paper is that the life of hedonism according to al-Tabari and Sayyid Muhammad Rasyid Rida is an excessive human lifestyle and indulges in lust in reaching the pleasures of the world. The similarities and differences according to these two mufassirs are almost the same in interpreting the life of hedonism in surah Ali Imran verse 14 that Allah SWT makes beautiful in human views of the pleasures of the world, namely women, children, large assets of gold and silver, selected horses, livestock and rice fields. Sayyid Muhammad Rasyid Rida besides agreeing with Imam al-Tabari, he added that human love for the beauty and pleasure of the world is not only specific to the Jews, but is general

Feasibility Study on the Operation of an Iron Heat Treatment Furnace with Hydrogen Fuel
No full textThe work presented in this report investigates the effect of replacing natural gas fuel in a radiant tube burner in an industrial furnace with hydrogen fuel. The flue gas is fully contained inside the radiant tube burner and does not come into contact with the iron products inside the furnace. The burner interacts with the process side of the furnace only by heat transfer. Therefore, the investigation could be divided into a study of two separate systems: the burner and the furnace systems. In the first part, the burner system was evaluated. The impact of changing the fuel of the burners from natural gas to hydrogen on heat-, flow- and radiation of the existing burner was studied. Moreover, the NOx generation has been considered. The investigations were performed using Reynolds Average Navier Stokes (RANS), Computational Fluid Dynamics (CFD) approach using detailed chemistry. Natural gas combustion was simulated as the basis for comparison. The result shows that the CFD model could estimate the NOx emission of the base case well. Next, the combustion with hydrogen was compared. The result suggests that the thermal efficiency of the burner is slightly higher with hydrogen fuel. On the other hand, the NOx emission is significantly higher. A modified burner including internal flue gas recycle was proposed and studied. The result shows that the modified burner can be operated at the same power and the same level of NOx emission as the existing system. Furthermore, different burner power could be applied in order to comply with the NOx emission limit or to increase processing speed. In the second part, a heat transfer analysis of the furnace has been performed. The model agrees well with measured data of furnace atmosphere temperature. The result suggests that having a higher burner power could increase the processing speed and reduce the energy requirement per ton of iron products.Electrical Engineering | Sustainable Energy Technolog
