It usually takes a few weeks to analyze dioxins concentration in flue gas from MSW incinerators by official method. In order to reduce the required time for analysis, we have developed an on-line measuring equipment for pentachloro-dibenzofuran(P_5CDF)and a real-time measuring equipment for trichlorobenzene(T_3CB). The following results were obtained from field tests carried out using these equipments. (1) The concentration of DXNs emitted can be estimated and monitored by measuring the concentration of P_5CDF contained in flue gas using a ultraviolet ionization mass spectrometer(VUV analyzer)(2)optimum operating conditions to reduce dioxins emission can be obtained by the T_3CB measuring equipment which relates to dioxins' behavior inside furnaces real-timely, and (3) these equipments can be applied in adjusting operating conditions during trial operation of an incineration plant by monitoring them and for basic research and development.
