摘要

围绕电站燃煤汞排放量估算

建立了典型燃煤锅炉汞排放量估算模型。在实测的典型电站燃煤锅炉汞排放数据基础上

确定了典型燃煤锅炉系统各部分的汞影响系数Fij。同时

估算了典型电站燃煤锅炉汞的年排放量。我国100 MW机组典型燃煤锅炉总汞排放量在40~50 kg/a左右。当尾部烟气部位仅布置静电除尘器时气态汞比例高达80%左右;当静电除尘和湿法脱硫同时布置时

气态汞排放比例降低至30%左右;当选择性催化还原脱硝、静电除尘及湿法脱硫等装置联合使用时

气态汞的排放降低至总汞量的15%以下。

Abstract

Centred on the estimation of mercury emission from coal-fired boilers in power plants

a model for estimating the mercury emission from typical coal-fired boilers has been established.Based on practically measured data of mercury emission from coal-fired boilers in typical power plants

the mecury emission affecting coefficient Fij in each part of typical coal-fired boiler system has been determined

at the same time

the annual mercury emission from coal-fired boilers in typical power plant being estimated.The total mercury emission from typical coal-fired boilers of of 100 MW unit is about 40~50 kg/year in China.In the event of only electrostatic precipitator(EP) being allocated in tail section of the boiler

the gaseous mercury emission ratio reaches up about 80%;in the case of EP and wet flue gas desulphurization(WFGD) system being simultaneously allocated

the gaseous mercury emission ratio decreased to 30% of the total mercury emission;if EP

WFGD

and selective catalytic reduction(SCR) being used together

the gaseous mercury emission may decrease below 15% of the total mercury emission.
