“…They reported that, with reduction in hole spacing, the curvature of flame base increases and the flame thickness decreases. Hindasageri et al 234 experimentally and numerically studied the heat transfer distribution of impinging flame from PP burner for three different configurations (inline, staggered, and star) over range of Reynolds number (50 to 600) and at three different pitch to diameter (p/d) ratios (1.67, 2.33, 3.33) but 7 mm pitch is considered optimal for the entire study. Oh, Shin, and Kim 235 reported that the oscillations induced by combustion in a PP burner can be well stabilized by decreasing the hole diameter or by reducing the plate thickness.…”

Summary The use of fossil fuel is expected to increase significantly by midcentury because of the large rise in the world energy demand despite the effective integration of renewable energies in the energy production sector. This increase, alongside with the development of stricter emission regulations, forced the manufacturers of combustion systems, especially gas turbines, to develop novel combustion techniques for the control of NOx and CO2 emissions, the latter being a greenhouse gas responsible for more than 60% to the global warming problem. The present review addresses different burner designs and combustion techniques for clean power production in gas turbines. Combustion and emission characteristics, flame instabilities, and solution techniques are presented, such as lean premixed air‐fuel (LPM) and premixed oxy‐fuel combustion techniques, and the combustor performance is compared for both cases. The fuel flexibility approach is also reviewed, as one of the combustion techniques for controlling emissions and reducing flame instabilities, focusing on the hydrogen‐enrichment and the integrated fuel‐flexible premixed oxy‐combustion approaches. State‐of‐the‐art burner designs for gas turbine combustion applications are reviewed in this study, including stagnation point reverse flow (SPRF) burner, dry low NOx (DLN) and dry low‐emission (DLE) burners, EnVironmental burners (including EV, AEV, and SEV burners), perforated plate (PP) burner, and micromixer (MM) burner. Special emphasis is made on the MM combustor technology, as one of the most recent advances in gas turbines for stable premixed flame operation with wide turndown and effective control of NOx emissions. Since the generation of pure oxygen is prerequisite to oxy‐combustion, oxygen‐separation membranes became of immense importance either for air separation for clean oxy‐combustion applications or for conversion/splitting of the effluent CO2 into useful chemical and energy products. The different carbon‐capture technologies, along with the most recent carbon‐utilization approaches towards CO2 emissions control, are also reviewed.

“…It is also seen that there is no information available in the literature using twisted tape as a swirler to study the swirling flame jet heat transfer characteristics of IDF. In the present work, the distribution of the heat fluxes on an impingement plate are studied by the novel method of inverse heat conduction problem (IHCP) in a semi-infinite medium using a thermal infrared camera [27][28][29]. The heat flux distribution is presented for the air jet Reynolds number (Rea) = 1000 to 2500 and burner to impingement plate distance (H/da) = 2 to 20 for a constant equivalence ratio (ϕ) of 1.1.…”

Flame jet has a wide range of applications in the industries and also in domestics field. The efforts have been put to enhance the heat transfer and to reduce the emissions from the premixed and inverse diffusion flame burners. Especially, the IDF burner suffers from lack of proper air and fuel mixing, the swirl generated motion from twisted tape would improve the combustion efficiency. Therefore, an aim of experiment is to study the heat transfer characteristics of an inverse diffusion flame (IDF) jet impinging on a flat surface in a coaxial tube burner with swirl. The twisted tape of 15mm pitch creates the swirl in the flame jet (Corresponding to the twist ratio of 3 and swirl number of 0.52). An effect of swirl at air jet Reynolds number of 1000 to 2500 and surface of the burner-to-impingement plate distance (H/da) varying from 2 to 20 is studied at fixed equivalence ratio (ϕ) of 1.1. An average heat flux and peak heat flux are studied for the region of 0<r/da<3 on an impingement plate. From an investigation, it is found that the swirling in the flame jet enhances the average heat flux by up to 179.2%. The maximum average heat flux is found at the optimal burner-to-target plate distance of 8.

“…Jets with an array can help to enhance the heat transfer for heating a large surface area and to avoid local hot spots [25]. Multiple impinging flame jet studies on laminar combustion have investigated the effects of flame jet arrays [26][27][28][29][30]. Experiments revealed the effect of the parameters on the local heat flux distribution on an impinging plate.…”

The temperature distribution on a steel plate during a preheating process was comparedusing gas torch models with and without guide vanes. Numerical simulations were done usingANSYS FLUENT software, and experiments were done using thermal images obtained by aTVS-200EX infrared thermal camera. Liquefied petroleum gas (LPG) was used as fuel for the gastorch in the simulation and experiment. The temperature distribution on the steel plate and theflame region were first compared. The temperature increase caused by the flame concentrationwith the guide vanes was 65 C. The transient and steady-state temperature distribution on theback side of the steel plate were then examined. The results showed good agreement between thesimulation and experimental results. At steady state, the back-side temperature deviation of thesteel plate between the numerical simulation and experimental results was approximately 4.9%.The effects of the equivalence ratio (Φ), Reynolds number (Re), and the downstream distance ratioof the combustion gas from the torch outlet to the steel plate (H/d) on the temperature distributionwere also investigated. The highest temperature distribution was found in stoichiometriccombustion. The temperature of the plate increased as the Reynolds number increased from 2368 to4876 but decreased as the distance ratio (H/d) increased from 25 to 75. The guide vane angles at thegas torch outlet were from 30 to 60 degrees, and the angle of 40 degrees resulted in the highesttemperature of the steel plate.
