Abstract: Abstract Faults such as high-temperature gas leakage and electrode rod leakage in the heater present substantial risks to operational safety and reliability. This study conducts three-dimensional modeling and coupling simulation analysis of a heater subjected to multiple physical fields. The heat transfer mechanism is first examined, followed by the development of a three-dimensional model of the heater incorporating heating elements and electrode rods. Using either simplified models or localized simulations, the coupled process of high-speed and high-temperature gas flow within the heater pipeline and the interaction between flow and heat transfer during the cooling of electrode rods are analyzed. Simulation results indicate that the bolt joint experiences peak electrode rod temperatures in the range of 20–80 °C under typical operating conditions. This range aligns closely with field measurement data, thereby validating the accuracy of the coupling simulation model.
