Abstract

This paper aims to monitor heating surface fouling degree of boiler without fume temperature data recorded. Based on the thermodynamics, this paper analyzes the heat balance mechanism of the heat transfer characteristics of the convection heating surface of the boiler and the endothermic characteristics of the steam and obtains the relationship between the heat transfer coefficient and the temperature difference and it is proved that the temperature difference between the heating surface and heat transfer coefficient has a strong correlation through the gray correlation analysis method. This paper analyzes the actual production data by correlation analysis and regression analysis: the amount of heat released from the combustion of the boiler is certain when the load is stable, and based on the model for the temperature difference of the working fluid to represent the degree of dust accumulation is established. This paper validates the result that the model is able to reflect the degree of dust deposition on the convective heating surface well by simulation and field data verification methods.
