Abstract
The main goal of the current study is to investigate how the gas stove burner geometry affects flame behavior and, consequently, combustion performance. To fulfill this objective, both natural gas and hydrogen-natural gas blends are experimentally investigated to assess their burning performance. Among the different geometries, six burner geometries are designed and manufactured for experimental studies. For each of the considered six burner heads, an identical volumetric flow rate of 5 liters per minute is used to evaluate the pure natural gas and the hydrogen-natural gas blend (by 30% volumetric hydrogen) to analyse how the geometry affects the flame distribution and burning quality. In different time steps of 1, 5, and 10 s, the flame picture is captured to compare its variations and combustion behavior. The experiments are repeated for every geometry to guarantee steady circumstances and produce accurate images. The experimental results show that by injection of the hydrogen, the height of the flame shortens while the flame color tends to be bluish, implying better combustion. This is more pronounced in the geometry with three lateral sets of holes and two circular sets of holes at the top of the burner. Furthermore, the present results show that the width to height ratio of the flame changes between 0.27 and 0.67.
期刊介绍:
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
