摘要
燃煤发电厂向大气排放的有害物质生要有烟尘、氮氧化物和二氧化硫.为了使环境质量在标准范围内,需对这三种物质进行监测.一般多采用“外测法”.这种方法由于受本底值、天气等因素影响,测量准确度较低.本文介绍一种新的监测技术,又可称“内测法”.即在除尘器出口烟道上安装仪器监测,应用计算机软件控制,能保证长期,准确地监测这三种污染物的排放浓度.
The power plant to burn coal towards free air exhanst pernicious substance mainly is flue dust, NOx and SO2.
In order that enable the quality of the environmetal within the standard limits, need to be monitoring for the three kinds pernicious substance.
Generally the great majority adopts 'external the survey means'.
Owing to the survey means accepts the effects of background value and weather, accuracy of measure is lower.
This text introduces a new technology of monitor. Again call 'inner the survey means' .
Id est installational instrument monitors to the flue of the exits of a duster, use control of computer software, be able to ensuring a long-term and accurate monitor for exhanst the density of the three kinds pernicious substance.
