[0002] The boiler used by the power plant to generate electricity is called the power station boiler. The energy consumption of the power station boiler is very large, so the current power station boilers are saving energy through various means. The current thermal power plant boilers often have the problem of low coal utilization rate and unclear energy-saving effect. It is necessary to analyze the energy consumption data of the thermal power plant boilers and calculate the energy-saving potential, so that the thermal power plant boilers can be repaired or replaced at any time to improve the energy utilization rate. The existing thermal power plant boiler energy-saving potential analysis is completed by comparing the theory with the actual use value over a period of time. The actual use value is only calculated by the average, and the calculation error is large. Because there are many influencing factors, such as the working environment temperature of the boiler, the boiler load rate and the use time (life) of the boiler, the calculation result is not accurate enough, and only the energy-saving potential analysis value in the current time period is provided. It is impossible to predict the subsequent energy-saving potential analysis trend and avoid risks in advance.
