摘要:

工业锅炉在能源转换方面具有非线性、时变性及热惯性大等特性，且易受燃料质量、环境风速等多种外部因素干扰，导致温度控制精度难以保证。因此为提高设备运行效率，现提出基于热电偶温度传感器数据采集的工业锅炉模糊PID温度控制。通过将锅炉输入能量分解为有效利用能量以及热量损失，并考虑排烟损失以及散热损失等因素，对热平衡方程进行构建。基于锅炉的热平衡方程和动态特性，建立主蒸汽温度与控制变量之间的数学模型，描述温度与燃料供应量、减温水流量以及锅炉负荷之间的关系。通过高精度热电偶传感器实时采集锅炉主蒸汽温度数据，并结合模糊控制器，计算燃料供应量与减温水流量调整值，实现对锅炉温度的精确控制。在实验中，对提出的方法进行了控制精度的检验。最终的测试结果表明，采用提出的方法对锅炉进行温度控制时，系统振荡次数较少，具备较为理想的控制效果。

Abstract:

Industrial boiler in the energy conversion with nonlinear, time-varying and thermal inertia characteristics, and susceptible to fuel quality, ambient wind speed and other external factors interference, resulting in temperature control accuracy is difficult to ensure. Therefore, in order to improve the operating efficiency of the equipment, the fuzzy PID temperature control of industrial boiler based on the data acquisition of thermocouple temperature sensor is proposed. The heat balance equation is constructed by decomposing the input energy of the boiler into effectively utilized energy and heat loss, and considering factors such as smoke loss and heat loss. Based on the heat balance equation and the dynamic characteristics of the boiler, a mathematical model between the main steam temperature and the control variables is established to describe the relationship between the temperature and the fuel supply, the desuperheating water flow and the boiler load. The main steam temperature data of the boiler is collected in real time by a high-precision thermocouple sensor, and combined with a fuzzy controller, the adjusted values of fuel supply and desuperheating water flow are calculated to realize the precise control of the boiler temperature. In the experiments, the control accuracy of the proposed method is examined. The final test results show that when the proposed method is used to control the temperature of the boiler, the number of system oscillations is less, and it has a more ideal control effect.
