Performance Analysis of Novel Perforated LPG Burner for Domestic Application

Abstract

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.
