Slip stream test of Cannon Technology`s LTO environmental system at Duquesne Light Company coal-fired Elrama Plant: Demonstration of an oxidative process
For the past decade, Cannon Boiler Works, Inc. has been developing a new low temperature process (LTO) for removing both nitrogen and sulfur oxides from exhaust gas streams. In this process, ozone is mixed with the exhaust gas and the NO and NO{sub 2} gas components are oxidized to higher oxides nitrogen in a plug-flow reactor. The exhaust gas stream is then fed to an absorber chamber where the nitrogen oxides are absorbed into an aqueous solution as soluble nitrates and the sulfur oxides as insoluble sulfites and sulfates. In order to answer questions about the suitability of the Cannon LTO System for applications in the field of coal-fired Utility boilers, it was proposed to Duquesne Light Company that a slip stream test be carried out using gases from the main exhaust duct leaving the ESPs. The most serious questions to be answered were whether the system could operate at the normal exhaust gas temperatures of utility boilers, whether the fly ash and S02 gases would interfere, and whether the stations normal scrubber lime slurry could be used as the absorbent for both the nitrogen and sulfur oxides leaving the LTO System`s reactor. The slip stream test was performed at the Elrama Station with the financial support of Duquesne Light Company and members of PERC. Preliminary results of the slip stream tests have shown that: (1) The Cannon LTO System performs well with coal-fired exhaust gases -- as it did with those from natural gas-fired burners, (2) 100% NO{sub x} removal was achieved and (3) the absorption of the higher oxides of nitrogen was almost unaffected by the pH of the aqueous absorbent.
