Principal Investigator / Author(s): Chang, Daniel P. Y. and Bell, Richard L.

Contractor: Department of Civil Engineering and Department of Chemical Engineering, UC Davis

Contract Number: A4-159-32

Research Program Area: Emissions Monitoring & Control

The California Air Resources Board (CARB) is charged with assisting the Department of Health Services (DOHS) and local air pollution control districts (APCDS) in evaluating applications to burn hazardous wastes in a variety of incinerators. Incinerator evaluation tests typically involve determining the destruction and removal efficiency (DRE) of the incinerator for selected principal organic hazardous compounds (POHCs), as well as determining the emissions of certain products of incomplete combustion (PICs). Because these tests require extensive analyses which are very expensive, unanticipated problems with sampling at the test site or subsequently with analytical methods can cause costly delays or require further testing.

The CARB has contracted with the UC Davis Department of Civil Engineering to investigate the feasibility of developing an experimental program to study hazardous waste incineration. Such a program would be geared toward improving the efficiency of conducting these tests, lowering test costs, and interpreting test results. The desired goals of an experimental program on waste incineration are:

1. To develop and test sampling methods for incineration studies.

2. To perform studies of products of incomplete combustion.

3. To study the effect of mixing of fuels on emissions.

4. To evaluate the feasibility of using surrogate hazardous waste compounds in incinerator studies.

5. To study the influence of various "failure conditions" on the destruction efficiency (DE) of hazardous compounds.

6. To determine the significant operational parameters such as minimum temperature, residence time, oxygen concentration, etc., for effective destruction of hazardous compounds.

7. To determine which surrogate compounds best represent complete combustion of the hazardous waste.

The purpose of this report is to assess the feasibility of the CARB's development of an experimental program in hazardous waste incineration. This study will focus on answering the following questions:

1. What can be accomplished in pilot scale and laboratory hazardous waste incineration studies?

2. What are the advantages, disadvantages, costs, and commitments of the following options:

a) CARB designs a test program then contracts for use of an existing facility to carry out the study.
b) CARB builds and operates its own facilities to carry out its studies.

3. What laboratory scale studies may be beneficial to CARB's hazardous waste incineration program?

This study will be divided into five sections: I. Benefits and Limitations of Pilot Scale and Laboratory Hazardous Waste Incineration Studies, II. Contracting for Use of an Existing Pilot Scale Hazardous Waste Incinerators, III. Development of a CARB Pilot Scale Hazardous Waste Incinerator, IV. Laboratory Scale Hazardous Waste Incineration Studies and V. Conclusions and Recommendations.
