The temperature of the steam is a crucial factor in the safe operation of the boiler, as overheating can lead to damage. To ensure the normal operation of the waste heat boiler, it is necessary to design a control system that maintains the outlet steam temperature at a set value. The design utilizes a single-loop control system with an AT89S51 single-chip microcontroller as the core. The system comprises various modules including temperature sensing, key processing, temperature display, control output, actuator, and communication. The key to temperature control lies in temperature measurement and temperature regulation. Temperature measurement technology is well-established; however, as control objects become more complex, there are still several challenges in temperature control. To overcome these challenges, this study adopts a PID algorithm for the design of the boiler temperature control system and utilizes Matlab/Simulink simulation software to simulate the control algorithm. The PID algorithm allows for precise temperature regulation and helps to maintain a stable steam temperature in the waste heat boiler. In conclusion, this paper presents the design of a temperature control system for superheated steam in a waste heat boiler using a single-chip microcontroller. The system employs a single-loop control approach and incorporates various modules for temperature sensing, control, and actuation. The PID algorithm ensures accurate temperature regulation and the Matlab/Simulink simulation validates the effectiveness of the control algorithm. This design contributes to the safe and efficient operation of waste heat boilers, preventing damage caused by overheating.
