In-Stack Continuous Monitoring of Emissions from Stationary Sources.

摘要

A study was performed on the status of technology of continuous monitors for emissions from stationary sources in California. About 700sources were identified which had emissions of 100tons/year or more of the contaminants considered (NOx, SO2,CO,particulates,hydrocarbons),and which were suitable for installation of a continuous monitor. Systems of stated reliability and moderate cost ($10,000to $20,000) were found to be available from several manufacturers. Direct reading of the mass rate of emissions and electronic data handling and storage were found to be feasible,effective options. Costs were estimated to be about 10% and 25%,respectively,of the basic monitor cost. Examples of specific applications of both in situ and extractive systems were prepared and are presented. The technology of continuous monitors was found to be well developed based on several years of field experience.
