Abstract A major problem associated with the use of coals in utility boilers is the tendency to form deposits on fireside heat transfer surfaces. The formation of ash deposits is a complex problem that at the present time cannot be accurately predicted based on coal composition and combustion conditions. The formation of tenacious deposits involves the transformation of inorganic coal components during combustion and gas-cooling phases and the interaction of ash components upon deposition. In many cases, specific inorganic constituents associated with coals playa key role in the formation of ash deposits in coal-fired combustion systems. For example, iron-rich species have been correlated with the formation of slag deposits in the radiative sections of combustors (1) and alkali and alkaline earth elements contribute to the formation of fouling deposits in the convective passes of combustors (2).
