Analysis of Fouling Degree of Individual Heating Surfaces

The paper presents the method of fouling degree evaluation of the heating surfaces in pulverized coal-fired boiler during coal combustion and biomass co-combustion. The fouling processes have a negative impact on the boiler operation by reducing the steam outlet temperature, increasing the mass flow rate of cooling spray water, and may be the reason for overheating of the superheater (SH) tube material.
