Title: In-stack continuous monitoring of emissions from stationary sources

Principal Investigator / Author(s): Arledge, K W

Contractor: KVB, Inc.

Contract Number: 3-733

Research Program Area: Emissions Monitoring & Control

Topic Areas: Stationary Sources


A study was performed on the status of technology of continuous monitors for emissions from stationary sources in California. About 700 sources were identified which had emissions of 100 tons/year or more of the contaminants considered (NOx, S02' CO, particulates, hydrocarbons), and which were suitable for installation of a continuous monitor.

Systems of stated reliability and moderate cost ($10,000 to $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. For many combustion devices the annual fuel cost savings that could result from continuous combustion control would equal the original monitor system cost. The technology of continuous monitors was found to be well developed based on several years of field experience.
