Analysis of an APCA Baghouse Operation and Maintenance Survey

Baghouse operation and maintenance is probably the most serious problem area of fabric filter operations. Committee TC-1 (Particulates) of the Air Pollution Control Association recently surveyed baghouse installations in'the United States for the purpose of gathering information on operation and maintenance procedures and problems. One hundred thirty-three questionnaires were completed and returned. In this paper, the results of a comprehensive analysis of these data are described and interpreted. A multiple-choice type of compilation of the responses has been used to permit statistical interpretation of the results. Due to the length of the questionnaire and the tables which resulted from the analysis, these are described but not included in the following paper. They are available from the TC-1 Committee c/o APCA.     

Air Pollution Research Problems

The TR-l Research Committee of the Air Pollution Control Association conducted a survey during 1969–70 to determine what air pollution research problems require attention. All APCA committees were requested to contribute topics to this survey, especially within their area of activity. Other professional societies were contacted through liaison representatives of APCA. The responses to the survey have been reviewed, categorized, selected, and edited for inclusion in this report. Additional material and concepts have been contributed by members of the TR-l Committee.     

“The Clean Air Act — A Time for Evaluation”

The Third Government Affairs Seminar sponsored by the Air Pollution Control Association was held in Washington, D. C. on April 16-17, 1975. The APCA South Atlantic Section was host for this very successful meeting. The General Chairman of the Seminar Committee was John V. Brink and the Program Chairman was Richard D. Grundy.

The seminar this year was conducted in three sessions. The first session, entitled “The Clean Air Act: State vs Federal Roles,” considered a topic that is receiving increasing emphasis as the national air pollution control program matures. This discussion was chaired by M. Barry Meyer, Chief Counsel and Chief Clerk, Senate Committee on Public Works.

The second session was “Land Use Planning Aspects of the Clean Air Act—Federal, State and Regional Roles.” Mrs. Mary Jane Due, Chairman of the Public Land and Land Use Committee, Natural Resources Section, American Bar Association, served as Moderator of this discussion of indirect source regulations, no significant deterioration, air quality maintenance—concepts that rely heavily on comprehensive land use planning.

“Clean Air Priorities—The Need for Flexibility,” was the title of the third session which was chaired by Austin H. Phelps, Manager Corporate Air Pollution Control, Procter and Gamble Company and President of APCA. The panelists considered the question of how appropriate the standard setting mechanisms of the Clean Air Act are for the resolution of present and future problems.

In this report condensed versions of the prepared statements of the participants are presented. A more extensive summary of the Proceedings, which includes questions and answers, is available from APCA headquarters. The remarks of John R. Quarles, EPA Deputy Administrator, who was the luncheon speaker, were summarized in the June APCA Journal(p. 642).

Summary of am APCA International Specialty Conference

Ozone continues to be one of the most important air pollution problems in the United States. While significant progress has been made, certain areas of the country still experience unhealthy levels of ozone and are unlikely to achieve current primary standards by 1988. With the prospect of an influx of millions of additional people, and their cars, into these areas by the year 2000, the problem of oxidant regulation and control becomes even greater. From this realization, the Effects Division of the Air Pollution Control Association conceived this conference topic. The summary that follows highlights key issues and findings from the conference held in November 1984 in Houston, Texas. The transactions of the conference will be available from APCA headquarters in the near future.     

Consultant Guide/1973

Grundy and Linda Duncan.     

Information Required for the Selection and Application of Electrostatic Precipitators for the Collection of Dry Particulate Material

This report is a continuation of two prior papers on the selection and application of electrostatic precipitators. The first papers submitted by the TA-5 committee of APCA were primarily concerned with the collection of fly ash from boiler gases. Three other major applications of industrial precipitators include the ferrous, pulp and paper, and cement fields. Other industries utilizing the precipitator but to a lesser degree are: chemical, petroleum, and non-ferrous metals. New application areas in the United States include municipal incinerators and high temperature-high pressure gas cleaning.

While a similarity of theory and equipment is common to all of the above applications, there are sufficient differences both in the processes and types of material collected to make the selection of the Individual precipitator subject to a comprehensive evaluation. In order properly to make this evaluation, it is necessary that a suitable means of communication be established between user and supplier. It is the purpose of this report to recommend ’? terminology, emphasize design factors, and list the information needed by the supplier to make a proper application of his equipment.     

Introduction

The following papers were presented at a technical session held during the 76th APCA Annual Meeting and Exhibition in Atlanta, Georgia in June 1983. The session, which focussed on the relationship between atmospheric deposition and forest activity, was organized by J. S. Jacobson and S. B. McLaughlin, Jr., and sponsored Jby APCA's TT-8 Acid Deposition Committee.     

Guidelines in Application of Explosion Vents

This paper is one of those presented at the APCA Specialty Conference entitled “The User and Fabric Filtration Equipment—III”, held in October 1978 in Niagara Falls, New York. It presents guidelines for the application of vents for explosion protection in fabric filter systems. Detailed design procedures will soon be available in the new edition of National Fire Prevention Association Code 68 on explosion venting.     

Operating History and Current Status of Fabric Filters in the Utility Industry

Electric utilities have made significant progress in recent years in designing and operating baghouses for collection of coal fly ash. As a result, early concerns with high operating and maintenance requirements and short bag lives are no longer an issue. With increasingly stringent air emissions regulations and imminent revision of the Clean Air Act, baghouses have become an attractive particulate collection option for utilities.

In order to keep its member utilities apprised of the latest design and operation and maintenance experience with baghouses, the Electric Power Research Institute has been conducting surveys of utility baghouse user experience. This paper presents results from the latest survey, conducted in 1989. A previous survey was conducted in 1985. The 1989 survey was conducted using questionnaires mailed to the utilities, telephone inquiries, and plant visits. This paper discusses the general trends observed in baghouse design, performance, operation and maintenance.
