The soot formation, evolution and morphology in inverse jet diffusion flame differ fundamentally from that of the normal jet diffusion flame (NJDF) due to its distinct reactant delivery mode and fluid dynamics. The unique feature of the IJDF configuration is its reduced soot formation as compared to the NJDF configuration, particularly at higher air-fuel velocity ratio, even for hydrocarbon fuels. The literature has reported six types of laminar IJDF based on visual appearance and air-fuel velocity ratio. Furthermore, laminar IJDF is mainly utilized as a lab-scale flame by various researchers for the fundamental investigation of soot evolution in nonpremixed flames.

This work provides a critical review of the recent research on organic pollutants from stationary coal-burning sources, including an overview of the effect of coal composition and coal source, the types of organics material in coal, the generation of organic pollutants during coal combustion, emission of organic pollutants, co-removal by air pollution control devices (APCDs), and the technologies used to remove organic pollutants from coal-fired power plants (CFPPs). Field sampling and analysis showed that the organic pollutants produced from coal combustion processes are mainly composed of volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and organic components in condensable particulate matter (CPM). The VOCs and CPM are mainly discharged into the atmosphere as part of the gas and particulate phases, respectively, whereas, PAHs are mainly concentrated in fly ash and bottom ash. The generation of organic pollutants during coal combustion is mainly affected by coal grade, temperature, heating rate, residence time, and pressure. Considering that the flue gas temperature and composition can vary from one CFPP location to another, the choice of the sampling methods is based on the specific needs of a CFPP. Because, the selection of a sampling method can significantly affect the final results and should be given special attention. Typical sampling methods for VOCs, PAHs, and CPM are summarized and their advantages and disadvantages are compared. The adsorption tube sampling method is more suitable for the sampling of VOCs because it is not limited by the volume and miscellaneous components of the flue gas. EPA Method 0010 and the dry impactor condensation method (EPA Method 202) are more suitable for sampling PAHs and CPM in flue gas due to their higher accuracy. The APCDs in CFPPs have organic pollutants co-removal abilities besides those for conventional pollutants. As a result, they can remove VOCs, PAHs, and CPM at efficiencies of 55.8–87.6 %, 74.7–89.8 %, and 36.3–81.5 %, respectively, with corresponding emission concentrations of 0.058–16.29 mg/m&lt;sup&gt;3&lt;/sup&gt;, 0.42–43.3 μg/m&lt;sup&gt;3&lt;/sup&gt;, and 5.9–65.1 mg/m&lt;sup&gt;3&lt;/sup&gt;. Based on current publicly reported data, the VOCs, PAHs and CPM contents emitted by global coal-fired power plants are estimated to be 88.1 Gg, 6.76 Gg (2.22 Gg in flue gas and 4.54 Gg in fly ash), and 600 Gg (organic components: 328 Gg, inorganic components: 272 Gg), respectively.

Furthermore, the mechanism for detonation initiation is also related to fire safety and industrial disasters. Thus, this review focuses on the recent progress made in the fundamental understanding of the mechanisms of end-gas autoignition phenomena along with detonation combustion in confined spaces through theoretical analyses, optical diagnostics, and high-resolution numerical simulations, with emphasis on the effects of crucial physicochemical factors on the two stages of end-gas autoignition, namely autoignition occurrence and autoignition propagation. Firstly, two basic theories, namely Livengood–Wu (L–W) integral and the reactivity gradient theory, which provide theoretical foundations for understanding autoignition occurrence and autoignition propagation, respectively, are demonstrated. Specially, applications and limitations of L-W integral and the extension of Bradley's diagram to multi-dimensional conditions closer to actual circumstances are elaborated. Then, a comprehensive investigation of several pivotal physicochemical factors involved in end-gas autoignition and detonation development in confined spaces, are conducted, including flame propagation, pressure wave, inhomogeneity, turbulence, chemical reactivity and thermodynamic conditions. The results indicate that, three essential elements are included in end-gas autoignition, namely flame, pressure wave, and autoignition. The flame-pressure interaction induced end-gas autoignition and detonation can be divided into three processes: I-reactivity increase, II-critical and sensitive state, and III-coupling and detonation. The first two processes account for autoignition occurrence and the third accounts for autoignition propagation. As to autoignition occurrence, increasing turbulence flame speed can inhibit end-gas autoignition under weak pressure wave conditions, whereas it can promote end-gas autoignition under strong pressure wave conditions. As to autoignition propagation, various combustion modes can originate from a reactivity gradient induced by temperature, composition, additive, as well as a cold spot within negative temperature coefficient (NTC) region, while the existence of low-temperature chemistry (LTC) and multi-stage ignition complicates autoignition propagation. The results further indicate that an inhomogeneous field with a small characteristic length scale, and an inhomogeneous field with a large characteristic length scale but coupled with the turbulence with a small characteristic length scale and a sufficiently large turbulent velocity fluctuation, can both weaken detonation propensity.
