Abstract This paper presents a newly designed coaxial burner capable of simultaneous combustion of oil and gas fuels. The burner addresses the need for renewable energy production from syngas and biofuels deri...ved from solid waste. The focus is on evaluating the burner's effectiveness in co-firing light diesel fuel and LPG, including flame appearance and exhaust emissions. The study establishes a reference for future comparisons when burning syngas and blended biofuels. The burner configuration allows for various influential variables, such as oil/gas ratio, and inner/outer air ratio. The evaluation concentrates on visible flame appearance, exhaust emissions, and heat transfer to the cooling water jacket. The experiments are conducted at a fixed 55 kW input load. Results indicate that different inner/outer air ratios have minimal impact on CO_2 and O_2 levels but affect CO and NOX levels, both in single fuel burning and co-firing scenarios. Increasing inner air reduces CO levels, particularly in oil fuel burning, while decreasing inner air reduces CO levels in co-firing.show more
