The release and behavior of mercury, selenium, and boron in coal combustion

摘要: The release of mercury, selenium and boron from coal is investigated at high temperatures using a drop tube furnace combustion test facility. results show that under conditions, most the mercury are released did not remain in fly ash temperatures, but some remains temperature. Under reducing all coal, char 1473 K. This indicates oxidation reaction contributes to coal. transfer these elements gas tested as function captured on below 773 K, capture ratio increases temperature decreases. small between 393 K 1273
