A pulverized coal/coke (PC) boiler combusts carbon-based fuel with substantially pure oxygen and a flue gas recirculation stream (containing predominately carbon dioxide) at varied ratios to achieve a desired boiler temperature profile while producing captured sulfur, a high purity captured COand electric power. The boiler includes at least one of (a) a mechanism for admixing a pulverized solid carbon-based fuel with an alkali metal salt and (b) injecting alkali metal salt into the boiler combustion zone containing a pulverized solid carbon-based fuel.

A hand-held apparatus and process for measuring the gap and mismatch of two adjacent surfaces. The apparatus includes two strobe lights positioned within a hand-held housing. An optical interface within the housing directs a portion of the light generated by each light source into substantially parallel planes which are projected out of the opening of the housing at converging angles onto the surfaces to be measured. A camera within the housing captures the resulting image and generates a signal corresponding to the image. A signal processor which includes a frame grabber card processes the signal generated by the array of detectors to thereby calculate the amount of gap and mismatch between the surfaces being measured.
