摘要:
The operation of a fossil-fueled thermal system (20) is quantified by obtaining a reference fuel chemistry before on-line operation (270), and thereafter operating on-line. In on-line operation (270), a set of measurable operating parameters is measured, including at least effluent concentrations of oxygen and carbon dioxide, and optionally the concentration of effluent water and the concentration of effluent sulfur oxide. An indicated Air/Fuel ratio is obtained, as are the ambient concentration of oxygen, and air preheater (36) leakage (29) and dilution factors. The fuel ash (Eq. 29) and fuel water are calculated, and the complete As-Fired fuel chemistry is calculated. From the complete As-Fired fuel (Eq. (13)) chemistry, the pertinent systems parameters such as reference fuel heating value, boiler efficiency (32)(Eq. 4(21)), system efficiency, fuel flow rate (Eq. 4(21)), total effluent flow rate (20), individual effluent flow rates (292), and individual emission rates (292) are determined in a fully consistent manner.

@ A system (128) wherein information relating to the performance and availability of equipment is utilized for purposes of appraising the future behavior of the equipment. One purpose, for instance, to which such an appraisal can be put is that of reaching decisions concerning the repair/replacement/refurbishment of the equipment. The subject system (128) includes performance means (130), availability means (132, degradation means (134) and updating means (136), all suitably connected in operative relation one with another. The performance means (130) is operative as a source of data pertaining to the performance of the equipment. The availability means (132), on the other hand, is operative as a source of data pertaining to the availability of the equipment. Continuing, the degradation means (134) is cross-linked to both the performance means (130) and the availability means (132), and is operative as a source of data pertaining to the degradation of the equipment. Lastly, the updating means (136) is operative as a source of data relating to the latest reported status of the equipment.
