The door of a medical waste pyrolysis incinerator plays a critical role in ensuring safe and efficient operation, as it must withstand extreme conditions, including combustion temperatures ranging from 1000 °C to 1200 °C and internal pressure. This study focuses on designing a door that is not only robust and airtight but also highly resistant to these high temperatures, ensuring both operational safety and environmental protection. The design process began with a combustion chamber capacity of 0.5 m3, with the incinerator body measuring 900 mm x 900 mm x 1200 mm and the door measuring 650 mm x 650 mm. The door was fabricated using steel with a yield strength of 245 MPa, equipped with locking bolts, and sealed with high-temperature-resistant asbestos to prevent leaks. The design was initially developed using 2D AutoCAD and 3D SolidWorks software. Analytical calculations were validated through SolidWorks simulations, revealing that the stress at the critical point was 58.185 MPa, providing a safety factor of 4.2 times above the yield stress. This robust design not only enhances the durability of the incinerator door but also contributes to the overall safety and effectiveness of medical waste management, supporting broader environmental safety goals. © Published under licence by IOP Publishing Ltd.
