Practical incinerator implications from a fundamental flat flame study of dichloromethane combustion

Abstract

This paper discusses a number of results obtained from a hazardous waste flat flame combustion study with implications to full scale incinerators. The results demonstrate that it is possible to obtain DREs of up to 99.95 percent firing mixtures of CH2Cl2/CH4 and air in such a facility. These results are significant since residence times are at the millisecond level. The paper presents DRE results obtained with this CH2Cl2 flat flame system when systematically varying the chlorine loading and equivalence ratio within the flames. Additionally, a PIC DRE is defined as an alternative approach to measure total stack emissions. PIC DRE results are presented for systematic variation of chlorine loading and equivalence ratio. Based upon the data of the paper, a suggested two-stage incineration process is presented which may be both economically advantageous and result in less total PIC emissions as compared with conventional incinerators for certain wastes. The data of this work further indicate that it is kineti...
