“…The average surface temperature obtained in this study was 544.8 o C for a flow rate of 0.25 L/min. Impact of using butane have also shown significant improvement in porous media burners [14,15]. Present work deal with compassion between utilization of alumina and zirconia porous media in reaction layer.…”

Occurrence of combustion phenomenon in porous media has always excited researchers to develop various shape and size of burner so that maximum utilization of energy can be taken achieved. Here in this experiential work, dual layer micro burner was exclusively built to carry out porous media combustion characteristic with different type of discrete material in reaction zone. Presently, only alumina and zirconia are compared in discrete form, while preheat layer was made of porcelain ceramic material (foam type). Reaction zone was restricted to thickness of 20mm while preheat zone at 10mm. A concept of equivalence ratio was aided since it involves premixed combustion of air and butane as fuel mixture. Additionally, burner was made to run under lean to ultra-lean modes and finest temperature were recorded. Both surface and submerged flame was generated effectively. Maximum temperatures recorded during surface and submerged flame condition was better by installing alumina rather than zirconia there by reaching a value of 631°C and 470°C respectively. Thus maximum thermal efficiency was calculated and found out to be 84%. Finally, emission parameters like NOx and CO where monitored and found out to be well within acceptable limits.

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.

The demand for efficient and eco-friendly domestic burner is a never-ending challenge. Enhancing combustion efficiency is achievable goal by ensuring better values for thermal efficiency and emissions. In this experimental research work, the performance of combustion in a developed domestic burner with Gypsum perforated plate in combustion chamber was investigated. Key parameters such as flame stability, maximum flame temperature, emission gases, and thermal efficiency with respect to Equivalent Ratio (ER) were reported.ER with is based on LPG and Air ranges from 0.75-1.4. In addition, the effect of number of Gypsum perforated plate in combustion chamber were altered. The results show that using two layers of perforated plates is beneficial. With only one layer of perforated plates enhancement in thermal efficiency at considered ER moved from 8% to 16%. Next, with two layers the value improved from 30% to 52% (if compared with no perforation combustion chamber). The computed percentage increase rise in values of developed burner was considerably high when compared with recently developed burner under this category. With emission analysis, a strong reduction in carbon monoxide emissions was observed, with marginal increase in NOx levels due to the higher flame temperature. Furthermore, Multi-Objective Optimization process was carried out using Pareto optimal front (POF) using two perforated layers at optimal cases.
