Abstract：Due to the increase in heavy oil prices and the proposal of the'double-carbon'goal,designing dual-purpose burners for oil and gas and enabling 100%load switching for both oil and gas usage has become a preferred choice for some petrochemical users.Based on the principle of calorific value equivalence,a 4-flame swirl burner structure is adopted,and the oil nozzle is designed using bubble atomization technology,the common air supply system is utilized to enable the free switching of the fuel.The results show that the efficiency of the 40 t/h boiler is 91.8%in the oil mode and 93.5%in the gas mode.The steam temperature,pressure,and evaporation volume all meet the design requirements,and the range of oil nozzle atomization steam consumption has been calibrated.The burner enables 100%load-free switching of oil and gas,allowing for flexible selection based on fuel prices,saving fuel costs,and having good economic,safety,and environmental performance.
