Special Issue Information

Dear Colleagues,

Recent natural disasters caused by climate change have reinvigorated concerns regarding carbon mitigation. Thus, advances in combustion processes and carbon capture are becoming a hot issue, with the number of studies on these topics growing rapidly. Moreover, issues related to combustion analysis, as well as the applications of emerging combustors to promote carbon capture, need to be deeply elaborated upon. This is a call for papers from the journal Processes for the Special Issue “Advances in Combustion Analysis and Carbon Capture of Emerging Combustors”. The Special Issue involves original research, reviews, and application papers. The topics cover but are not limited to: Strategies on Carbon Mitigation, Carbon Capture Technologies, Advanced Combustion Technologies, and Improvements in Combustion Analysis.

The related keywords on the above-mentioned topics are listed below:

  • Strategies on Carbon Mitigation: Life Cycle Assessments of Carbon and the Circular Economy of Carbon.
  • Carbon Capture Technologies: Chemical, Physical, and Biological Methods.
  • Advanced Combustion Technologies: Oxy-fuel, IGCC.
  • Improvements in Combustion Analysis: Fluidized Bed Reactors and Computational Fluid Dynamics.

The papers accepted for this Special Issue will be published in MDPI’s Processes journal under open access. Each submission to the Special Issue should contain new material, e.g., in the form of technical extensions, in-depth evaluations, or additional-use cases. A comprehensive peer-review process according to the journal’s rules of action will be carried out for each submission during the selection period. At least two technical committees will review each submitted article, and additional external reviewers will be invited to provide a high-quality review process.

We are looking forward to your compelling submission.

Kindly regards,

The Helmholtz method is developed to predict the self-excited thermoacoustic instabilities in a gas turbine combustor, combining flame describing functions, the measured damping rates under the firing condition, and the non-uniform spatial distributions of the physical parameters. The impact of the hydrodynamic and geometrical parameters on the thermoacoustic instabilities is investigated. The measured damping rates show lower values under a hot condition compared with those in a cold state. The experimental results indicate that the relative errors of the predicted eigenfrequencies and the velocity fluctuation levels are below 10%. The pressure amplitude decreases and the phase increases in the axial direction, indicating a typical 1/4-wavelengh mode. At a higher equivalence ratio, the mode shape in the axial direction becomes steeper due to the elevated fluctuation amplitude at the pressure antinode after enhancing the thermal power. When the air flow rate increases, the discrepancies between the pressure shape on the flame tube side and that on the plenum side are reduced. The velocity fluctuation level increases as the combustor length increases at a constant damping rate. In fact, the velocity fluctuation level first increases and then declines, caused by more significant damping rates when employing longer flame tubes. Self-excited thermoacoustic instabilities can be well predicted using the proposed method. Full article

Considering the worsening of global warming, development of efficient strategies in carbon capture process is essential. The chemical looping process (CLP) is considered a promising method applicable in various carbon capture strategies. In pre-, post-, or oxy-fuel combustion strategies, the efficiency of CLP has been explored and tested. This review discusses the applied CLP in each type of carbon capture strategy. Chemical looping gasification and reforming are categorized in the pre-combustion system. On the other hand, the popularity of calcium looping and amine looping are recognized as post-combustion strategies. Additionally, numerous oxygen carrier materials have been determined to reach high efficiency in oxy-fuel combustion. The review of the characters and the principle of the method was complemented by justification for real-scale application. Nonetheless, the popularity of CLP’s real implementation as a carbon capture strategy was still limited by several factors, including required cost for the facilities and energy demand. Thus, analysis on the prospect of CLP utilization was also included in this study. Full article
