摘要：Lab-scale investigations have been conducted on the impact of additives on the abatement of chlorine corrosion induced by combustion or co-firing of agricultural biofuels in boilers. The effect of potassium retention and chlorine liberation was examined applying domestic aluminosilicates. The following additives were examined: kaolin, bentonite, halloysite and lignite fly ash. The samples of potassium chloride and the additive mixtures were heated in the muffle furnace at the temperature range 600–1000 ºC. The obtained sintered samples were examined on: chlorine content, potassium retention and crystalline structure. Three minerals additives (kaolin, bentonite and halloysite) appeared to be effective in potassium binding in high temperature melting potassium aluminosilicates and in liberating chlorine at the temperature range 800–1000 ºC. Also the aluminosilicate type lignite fly ash can be considered as very effective and inexpensive additive that prevents chlorine corrosion during biomass co-firing.
