Abstract
In order to make full use of surplus gas, metallurgical gas boilers have been widely applied in steel mills, especially in China, India, and other Asian countries. The leakage of air preheater is one of the common faults of metallurgical gas boiler. It is helpful for the steady operation of gas boiler to grasp the air preheater leakage rate in real time. However, the current methods for measuring the air leakage rate cannot be used in online monitoring for metallurgical gas boiler. According to the characteristics of metallurgical gas and the definition of air leakage rate, this paper deduced an online method for measuring the air preheater leakage rate, which is suitable for metallurgical gas boiler and has good practicability. Finally, the online model was verified by experimental data. The results show that the proposed model has high accuracy and can meet the engineering requirement.
