Introduction. Arsenic is one of the most volatile and potentially toxic elements to be released from coalfired power plants. Arsenic is primarily volatilized as As 2 O 3 (g) during hightemperature combustion process [1], [2], more than 80% of which is partitioned into the fly ashes afterward and eventually captured by dust removal device [3].

features of major types of coal used for power generation are listed in Table 1. Pulverised coal (PC) is the fuel used in about 97% of the world's coalfired capacity (IEA, 2008). In a pulverised coalfired power plant, coal is milled and burned with air in tall boilers that provide for complete burnout and efficient heat transfer.
