"基于单片机的余热锅炉蒸汽温度控制系统设计研究"

The superheated steam temperature is an important parameter that affects the safe operation of the waste heat boiler. If the steam temperature is too high, it can weaken the metal strength of the superheater wall and potentially lead to overheating and damage. To ensure the normal operation of the waste heat boiler, a control system must be designed specifically for its characteristics to maintain the outlet steam temperature at a set value. This thesis focuses on the design of a control system for the superheated steam temperature of a waste heat boiler using a single-loop control system. The system is centered around the AT89S51 single-chip microcontroller and consists of modules for temperature acquisition, key processing, temperature display, control output, actuator, and communication. The key to temperature control lies in temperature measurement and control. While temperature measurement technology is mature, there are still challenges in temperature control, especially with increasingly complex control objects. The thesis employs a PID algorithm for the design of the boiler temperature control system and utilizes simulation software Matlab/Simulink to simulate the control algorithm. The study aims to address the issues in temperature control with a focus on superheated steam temperature in waste heat boilers. Key words: single-loop, superheated steam, single-chip microcontroller, temperature control. Overall, this thesis provides valuable insights into the design and implementation of a control system for the superheated steam temperature of a waste heat boiler, ensuring safe and efficient operation. The use of advanced control algorithms and simulation tools demonstrates the feasibility of the proposed system and lays the foundation for further research in the field of waste heat boiler control systems.
