TL;DR: In this paper, the steady laminar counterflow diffusion flame exhibits a very similar scalar structure as unsteady distorted mixing layers in a turbulent flow field, and the conserved scalar model is interpreted as the most basic flamelet structure.

TL;DR: In this paper, a comprehensive model of high temperature hydrocarbon oxidation in combustion is presented, with emphasis on the hierarchical structure of reaction mechanisms for complex fuels, including both inhibition and promotion of combustion.

TL;DR: In this paper, the authors examined the geometry and thermal radiation characteristics of large hydrocarbon pool fires and concluded that the analysis and correlation results could be used as a sequential algorithm for the evaluation of thermal radiation hazards produced by hydrocar pool fires.

TL;DR: In this article, the Damkoehler number, the Lewis number, and the Arrhenius number are discussed on physical bases within the framework of the three non-dimensional parameters of interest to heat and mass transfer in chemically-reacting flows.

TL;DR: A review and evaluation of the development of coal-reaction models is presented in this article, where the state of development of models for fixed (or slowly moving) beds, fluidized beds and suspended (or entrained) beds is presented.

TL;DR: The Brigham Young University's coal combustion research has been extensively studied over the past decade as discussed by the authors, with a focus on pulverized coal processes and the development and application of coal combustion models.

TL;DR: In this paper, the authors describe the characteristics of the mineral matter in coal, show how the non-combustible material behaves at the high temperatures of boiler furnaces, explain how coal ash can lead to metal wastage by erosion and corrosion, and review problems in the collection of flyash attributable to coal ash composition.

TL;DR: In this paper, the authors present an overview of non-intrusive diagnostic techniques that are suitable for measurements on coal-combustion systems, such as X-ray and microwave or longwavelength infrared tomography.

TL;DR: Improved and new methods for direct coal utilization are reviewed in this paper, including the following: direct burning of pulverized coals, clean-fuel-combined-cycle systems, atmospheric pressure fluidized-bed combustion, advanced and pressurized fluidized bed combustion, slagging combustors, coaloil mixtures, coal-water mixtures and other coal slurries, etc.

TL;DR: In this paper, a broad review of the available technology, the implications of using coal-derived fuel gas a substitute for conventional fuels, and the economic viability of on-site fuel gas generation are discussed.
