| 摘 要： | 为了研究燃煤过程中铅的排放量及其环境效应,对西安市燃煤电厂的原煤、底灰、飞灰的含铅量,采暖期燃煤锅炉的原煤和炉渣的含铅量,采暖期和非采暖期降尘的含铅量等进行了分析和测算.结果表明: 燃烧1 t含铅量为30 g左右的煤,排放到大气中的铅为20 g左右.燃煤中铅的排放率为66%左右.西安市及邻区每年工农业和民用燃煤1000万t左右,主要为渭北石炭-二叠系煤,含铅量为30 g/t左右,其每年排放到大气中的铅为200t左右.

| Abstract: | For study the lead emission amount from coal combustion and its environment effect, the lead content of coal, ash and cinder of power station and coal-fired boiler, the lead content of dusts in the period of heating time and the non-heating time in Xi'an City were studied in this paper. The results show that amount of lead emission from 1 ton coal combustion, which lead content in coal was 30 g, was 20 g in atmosphere. The rate of lead emission of coal combustion was about 66%. About 10 million tons of coal was straight burning every year in Xi'an City and suburb, those coal mainly come from Permo-Carboniferous coal in Weibei coal mine, Shaanxi, their average lead content was 30 mg/kg. So the total lead emission from coal combustion to atmosphere was about 200 t annually in Xi'an City. |
