Alkali Salt Ash Formation in Four Finnish Industrial

2019-3-10 · Combustion aerosol measurement methods were introduced and applied for extensive ash formation studies at four operating recovery boilers in Finland. Ash particle mass size distributions determined with a Berner-type low-pressure impactor downstream the heat exchangers were clearly bimodal with the fine mode at about 2 μm and the coarse mode above 3 μm aerodynamic diameter.
