融合机理与数据驱动的超超临界锅炉水冷壁温度预测模型
Fusion Mechanism and Data-Driven Prediction Model for Water Wall Temperature of Ultra Supercritical Boilers
摘要
Abstract
The temperature field inside the furnace has a high degree of nonlinearity and strong coupling,which makes it difficult to accurately predict the temperature of water-cooled walls inside the furnace,therefore,a fusion mechanism and long short term memory(LSTM)modeling method is proposed to establish a water-cooled wall temperature mecha-nism model considering the temperature inside the furnace,and to establish a data-driven LSTM model for water-cooled wall temperature.The mechanism and data-driven model reliability evaluation indicators are constructed,and used as model switching conditions.The wall temperature data of a 1 050 MW ultra supercritical boiler during the half year are used as the test set,and the results show the average temperature error is less than 0.4%,and the maximum error does not exceed 1.5%.The method proposed in this article has certain advantages in accuracy and robustness,providing a new solution for accurate calculation of water-cooled wall temperature.关键词
