Ghazal, R.M.Akroot, A.Wahhab, H.A.A.2024-09-292024-09-2920231823-4690https://hdl.handle.net/20.500.14619/10192The laminar burning velocities of liquid petroleum gas (LPG)-hydrogen-air mixtures are emphasized. They play a crucial role in designing and predicting combustion progress and the performance of combustion systems that utilize hydrogen as fuel. This work uses laminar burning velocities of different compositions of Iraqi LPG-hydrogen-air mixtures (4 and 10 vol.%). The measurements have been taken at ambient temperature and pressure for various equivalence ratios (? = 0.21 to 1.23). A counter combustor with a symmetrical premixed flame is suggested to enhance stability efficiency and temperature distribution and improve heat transfer with hydrogen gas addition at different percentages. The results have been demonstrated by an increase in the hydrogen concentration within hydrogen-LPG mixtures (0, 4, and 10%vol. of hydrogen) leads to a significant increase in both flame temperature (1070, 1100, and 1154 K) and burning velocities (26.7, 33 and 49.5 cm/s) respectively. Adding hydrogen to LPG makes it an excellent substitute for hydrocarbon fuels since it provides a stable flame and a large explosive area. © 2023 Taylor's University.
