Abstract
Mercury liberated during coal combustion can be either discharged as vapor in the flue as or retained in the furnace ash. About 90 percent (by weight) of the mercury released from a furnace fired with pulverized coal appears to be in the vapor phase, and 10 percent remains with the furnace residual ash. For a 700-megawatt unit, approximately 2.5 kilograms of mercury per day are released.
摘要
在煤炭燃烧过程中释放的汞可以以蒸气的形式排放到烟道中，或者被保留在炉渣中。大约 90%（按重量计）从煤粉炉中释放的汞似乎处于蒸气相，而 10%的汞残留在炉渣中。对于一个 700 兆瓦的机组，每天大约释放 2.5 公斤的汞。
