“…Te oxy-enriched combustion or incineration (OEC) of MSW appears capable of addressing the conventional incineration issues, through the use of O 2 /N 2 as an oxidizing agent with an oxygen concentration higher than 21% (typically lesser than 30%). Te uses of OEC have several merits, such as high combustion efciency, low pollutant emissions (CO 2 concentration of only 30-40 vol%), acceleration of combustion speed, and promotion of combustion safety [67][68][69].…”

Oxygen, an odorless and colorless gas constituent of the atmosphere, is a vital gas component for the Earth, as it makes up 21% of the composition of the air we breathe. Apart from the importance of oxygen for human breathing, its highly pure form is demanding for industrial applications. As such, several technologies have been established to increase the oxygen purity from 21% to somewhat higher than 95%. One of the competitive technologies for producing this high-purity oxygen from the air is through pressure swing adsorption (PSA), which has the advantages of low cost and energy while being highly efficient. Also, PSA is a simple and flexible system due to its ability to start up and shut down more rapidly since its operation occurs at ambient temperature, which is enabled through the use of adsorbents to bind and separate the air molecules. The enhancement of the PSA’s performances was reported through the modification of PSA step cycles and material (zeolite) tailoring. A simplified complete set of a mathematical model is included for modelling the PSA system, aiming to ease the experimental burden of the process design and optimization of an infinite modification of PSA step cycles. Finally, some technological importance of oxygen production via PSA, particularly for onboard oxygen generation system and oxy-enriched incineration of municipal solid waste, was discussed. Continuous development of PSA will make significant contributions to a wide range of chemical industries in the near future, be it for oxygen production or other gas separation applications.

“…As it comes to lean combustion, there are serious issues to take care of, such as extinction of the flame. Riahi et al [10] published an article on the subject, which investigates the effects of the change in fuel richness (from 0.7 to 1.0), hydrogen enrichment in the fuel and oxygen enrichment of the oxidizer on the flame structure and its stability and emissions. Particle Image Velocimetry was used to observe the flame form and the dynamic changes on it as well.…”

Verimsiz enerji kullanımı, kaynakların hızla tükenmesinin ve aynı zamanda tam yanmanın gerçekleşmediğine işaret edebilecek, yüksek orandaki emisyonlara bağlı küresel ısınmanın ana nedenlerinden biridir. Genel olarak, toplu sistemler ya da büyük ölçekli sistemler yukarda belirtilen problemlerin en büyük pay sahibidirler. Endüstriyel yakıcılar metal şekillendirme sanayisinde ve büyük ölçekli elektrik üretim süreçlerinde yaygın bir şekilde kullanılmaktadır. Bu alanlarda, hem karbon hem de azot bazlı emisyonlar için katı kurallar vardır. Buradan yola çıkarak, bu çalışma, çevresel kirleticilerin minimize edilmesi için oksi-yakıt yanması, yanmış gazların iç devirdaimi ya da ön karışımlama gibi konsept ve tasarımları içeren farklı teknikler kullanarak, yanma verimi ve emisyon düşüşü açısından iyileştirme sağlamayı amaçlamaktadır. Bütün sonuçlar birbiriyle karşılaştırılmış ve birçok parametreyi içeren tablolar ile sıcaklık konturları şeklinde verilmiştir. Bazı konseptlerin diğerlerinden performans ve emisyonlar açısından daha etkin olduğu gösterilmiştir.

To understand the role of functional groups in the spontaneous combustion of lignite coal, the distribution of functional groups in the lignite coal of the Sajau Formation in the Berau Basin, Indonesia, was studied. The functional group characterization was carried out using the Fourier Transform Infra Red (FTIR) method. The results revealed the presence of four functional groups, namely hydroxyl structures, aliphatic structures, oxygen-containing structures, and aromatic structures. The lignite contained more hydroxyl and oxygen-bearing functional groups, from which aliphatic and aromatic; therefore, spontaneous combustion becomes easy in lignite coal.
