“…The value of is kept unaltered thought out the experiment since the amount of butane supplied is kept constant. The calculated thermal efficiencies at maximum surface and submerged flame where at par with previously performed experimental work by researchers [10,13]. Among the three reaction layer considered the maximum with surface flame is seen at t=20mm, while with under submerge flame t=10mm can be an ideal choice.…”

“…FIGURE 9 indicates the top view of the reaction zone at ER 0.3 with t=10mm, a gradual distribution of temperature can be encountered with the help temperature scale, at this stage experimental measured value was 714 o C, but the displace image has indicated >620 o C, this is due to device limitation, it can able to reach maximum of 620oC. FIGURE 10 indicate the wall temperature distribution of the burner with t=20mm at ER=0.6 which is under surface mode.Since the current experimental works deal with micro burner, size of the reaction layer size is very less as compared to the whole burner housing [5,10], so the emission produces is low. Burner was tested for its emission characteristics using gas analyser at various ER.…”

“…Emission particles generated from combustion in micro burner are analyzed using KANE-9106 QUINTOX Combustion Analyser (made in UK) which is professionally built for measuring low emission with accuracy if 1ppm (parts per million). Moreover, actual picture of the experimental setup can be seen in FIGURE 3.An expression used to compute ER is as shown in Equation (1), where the actual air-fuel ratio ( ) was directly noted from the experimental procedure, while stoichiometric air fuel ratio ( ) for butane gas, was can be calculated by considering Avogadro's and Dalton's laws [10], which was computed a value of 30.95 with air at room temperature.…”

“…It can be easily identified that a large amount of numerical and experimental research has already been published by using PM in making novel burners [6][7][8], but still many technical parameters can be still tested to make the upcoming burner more efficient and reliable. Moreover, most of the previous work done on PMB has taken LPG as source of fuel rather than pure propane or butane, the one of the possible reason for selecting LPG is its ease access [9,10]. As far as the authors are aware, most of the past research works performed where mainly restricted to predefined thickness of reaction layer with a fixed equivalence ratio ( ).…”

Abstract.The applications of porous media burners are of often keen interest to researchers because of many modern advantages, such as high thermal efficiency, stable flame and low emission rate. In this current experimental work, a microburner was made built to achieve both surface and submerged flame for three different thicknesses of reaction layers. A reaction layer of discrete alumina with a predefined thickness of preheat layer was used for combustion. Reaction layer was accordingly replaced with different thicknesses of 10mm, 20mm and 30mm. This work mainly aimed to show burner behavior with increase in thickness of reaction layer thus suggesting the optimum equivalence ratio from best burner performance. Interesting and unique behavior of the burner was encountered for each thickness of the reaction layer. Highest surface temperature was found out with 10mm of reaction layer, while highest wall temperature was incorporated with 20mm of reaction layer. Equivalence ratio of 0.3 is best suitable for optimum performance of the burner. Finally, thermal efficiencies were calculated for surface and submerged modes at optimum equivalence ratio. Emission parameters, such as NOx and CO were also taken into consideration.

“…So both developed and developing nations prime moto is to come up with novel idea for improving the systems running of depleting fuels. In present scenarios super-fast demand has seen in liquid/gas fuels since large position of mankind depend on them to run their routine life like burner and stoves [4,5]. Hence one of the advanced and promising agent can be used so called porous media (PM).…”

Abstract. Addition of porous materials in reaction zone give rise to significant improvements in combustion performance. In this work, a dual layered micro porous media burner was tested for stable flame and emissions. Reaction and preheat layer was made up of discrete (zirconia) and foam (porcelain) type of materials respectively. Three different thickness of reaction zone was tested, each with 10, 20 and 30mm. Interestingly, only 20mm thick layer can able to show better thermal efficiency of 72% as compared to 10 and 30mm. Best equivalence ratio came out to be 0.7 for surface and 0.6 for submerged flame conditions. Moreover, emission was continuously monitored to detect presence of NOx and CO, which were under controlled limits.

Thermal Emission‐Enhanced and Optically Modulated Radioisotope Thermophotovoltaic Generators

Infrared radiation generated by high‐energy‐density radioisotope decay can be converted to electrical energy in radioisotope thermophotovoltaic (RTPV) generators. Thermal emission intensity and spectral properties have substantial implications in this thermal energy conversion process. To improve the performance of the RTPV generator, a silicone coating material is used as a thermal emission enhancer, and SiO2 is used as a filter. The silicone coating has excellent thermal emissivity at high temperatures. The SiO2 filter is used for optical modulation during the thermal energy conversion process. The heat transfer optimization problem caused by the internal temperature distribution of the system is discussed. Compared with the experimental model before optimization, the output power of the RTPV generator increased by 126% obtains an open‐circuit voltage of 2.64 V, an electric power of 89.88 mW, and an energy conversion efficiency of 5.62%. The RTPV generator is expected to be a potential candidate for energy supply in extreme environments.
