This paper presents a method to estimate the thermal performance of a pulverized-coal-fired boiler based on the detailed information on minerals in coal and a number of mathematical models. These models include transformation of minerals to ash, transportation of ash to heat transfer surfaces, stickiness of ash particles, and thermal properties of deposits.
