摘要: Abstract The combustion of herbaceous biomass can lead to deposit formation on the walls chamber and boiler tubes. These deposits are being caused by fly ash. aim present investigation was identify mechanisms formation, analyse chemical morphological properties deposit, propose measures for reduction. Special attention given from flue gas having been cleaned large particles. It is typically found in boilers moving bed furnaces. Experiments were performed a turbulent flow reactor sampling depositions cooled cylinder after removed particles an obstacle. Furthermore, two furnaces collected. investigations show that similar those achieved when before sampling. identified as accumulations fine nanometer range. KCl, major compound deposit. Among different thermophoresis revealed be crucial process under investigated conditions.
