Description:
The report gives results of an intensive examination and characterization of a coal-fired boiler prior to retrofit of a full scale flue gas desulfurization (FGD) unit employing the Wellman-Lord/Allied process. The test established a baseline profile of the boiler for later comparison both with design and operating conditions of other boilers for which the Wellman-Lord/Allied process is potentially applicable, and with operating performance after retrofit of the FGD unit. It also established a baseline profile during operation of the boiler at conditions other than normal which have the potential for affecting the performance of the Wellman-Lord/Allied FGD unit. Boiler operating performance was examined for its economic performance, overall energy balance, and the performance of auxiliaries. Detailed profiles of the flue gas at the proposed boiler/FGD unit interface were determined at varying boiler control settings including operation at below normal sulfur, higher than normal flue gas volumes, and higher than normal grain loadings. The tests were performed on Boiler No. 11 of Northern Indiana Public Service Company's Mitchell Power Station.
