Abstract

The effect of ammonium dihydrogen phosphate (NH4H2PO4) on the migration and transformation of potassium (K) during rice straw combustion was carried out in a laboratory-scale tube furnace at temperatures of 750 °C, 850 °C, and 950 °C. The characteristics of ashes were analyzed by chemical fractionation, scanning electron microscopy, X-ray fluorescence and X-ray diffraction. Results indicated that with the temperature increasing, the higher PO43−/K molar ratio, the stronger the ability of K-retention. When the molar ratio of PO43−/K was 1:1, the change rate of K retention increased by 4.95%, 23.12% and 47.99% compared to 1:2 molar ratio of PO43−/K at 750 °C, 850 °C and 950 °C, respectively. Water-soluble potassium of RS reacted with PO43− actively and was converted to insoluble potassium, which could avoid potassium migrating into gaseous phase. The addition of NH4H2PO4 can combine with K and Ca to generate the ternary complex salts of Ca–P–K. The compounds are mainly in the form of K2CaP2O7 that has a high melting point, which can improve the ash melting characteristics effectively.
