The formation of submicron ash particles during the utility-scale pulverized combustion of South African Klein Kopie and Colombian El Dorado coals was studied by measuring the ash particle number and mass size distributions in the size range 0.01--1 {micro}m upstream of the electrostatic precipitator (ESP). Ash morphology, composition and microstructure were studied by high resolution scanning and transmission electron microscopes (SEM and TEM). The authors propose new mechanisms for the formation of submicron agglomerated ash particles in pulverized coal-fired boiler flames.
