Ash Deposit Properties and Radiative Transfer in Coal Fired Plant — Current Understanding and New Developments
Previous research has offered speculations relating the physical and chemical character of ash deposits and their radiative properties. Recent work has confirmed that the physical character — whether the deposit is particulate, sintered or fused, or slag — has the dominant effect. Both online measurements and theoretical predictions suggest that measurements of emissive or reflective spectra from deposits may be used to identify this physical character and possibly the chemical species comprising the deposit, as an aid to on-line cleaning.
