The development of efficient and sustainable pyrolysis reactors is critical for advancing bioenergy technologies and waste management. This study presents the design and stress analysis of a pyrolysis reactor incorporating a rocket stove and an advanced heat transfer system, using Autodesk Inventor 2016. The integration of a rocket stove ensures efficient combustion and high-temperature stability, while the advanced heat transfer system maximizes thermal distribution within the reactor, enhancing the pyrolysis process. Stress analysis revealed critical stress points and informed design optimizations to ensure durability and safety. This innovative design approach, validated through advanced simulation tools, offers a significant advancement in the development of sustainable and efficient pyrolysis reactors. The safety factor is defined as the ratio of maximum allowable stress to equivalent stress. The permissible stress value for stainless steel components used in pyrolysis tubes is 187.5 MPa. The stress analysis test revealed that the reactor tube experienced a maximum equivalent stress of 17.72 MPa. The reactor’s design, incorporating materials capable of withstanding high temperatures and stresses, ensures safe and reliable operation. Stress analysis and the implementation of appropriate safety factors play a critical role in maintaining the reactor’s structural integrity.
