摘要
There is provided a method and apparatus for removing selenium oxide in a sample as well as a method and apparatus for measuring mercury in coal combustion exhaust gas by using the same. The apparatus for removing selenium oxide in a sample, comprising: (1) a heating introduction path for heating a sample, (2) a primary cooling unit having a flow path through which the heated sample flows countercurrently to cooling water, whereby the heated sample is mixed with, and cooled by, cooling water, (3) a secondary cooling unit having a spiral flow path for cooling the mixed gas and having a space for gas/liquid separation at the end of the spiral flow path, (4) a regenerator for introducing condensed water from the secondary cooling unit, and (5) a condensed water-cooling path for connecting the regenerator to the primary cooling unit.
