General Background: Waste management and alternative energy utilization are critical challenges in sustainable engineering systems. Specific Background: Conventional combustion systems often rely on mechanical devices such as blowers to improve combustion, which increases complexity and energy consumption. Knowledge Gap: Limited studies integrate steam boiler systems directly into combustion processes to generate airflow without additional mechanical assistance. Aims: This study aims to design and analyze a steam-assisted combustion stove using waste oil as fuel, focusing on thermal performance, steam generation, and flow characteristics. Results: The system employs a steam boiler with dimensions of 40 × 40 × 40 cm, producing steam at a rate of 0.0170 kg/s with a required heating power of 38,382 W and fuel consumption of 1.2 kg/h. Simulation results show flow velocities ranging from 52.8 m/s in the pipe to 531 m/s at the nozzle, indicating significant acceleration due to geometric constriction. Novelty: The integration of a steam boiler into a combustion system enables the conversion of thermal energy into kinetic energy flow without mechanical air supply devices. Implications: The design provides a practical solution for improving combustion performance using waste-derived fuel while maintaining system simplicity and safety.
