Technical notes for the conceptual design for an atmospheric fluidized-bed direct combustion power generating plant. [Comparison of AFB plant and pulverized coal plant]

doi:10.2172/6742704

Abstract

The first part of this report presents a comparison of the conceptual designs of a large (570 MW(e)) pulverized coal (PC) steam generator equipped with a wet limestone flue gas desulfurization (FGD) system and two equivalent sized atmospheric fluidized bed (AFB) steam generators including balance of plants for electric-power generation. The reader is cautioned that this portion of the report compares a zero generation AFB technology to pulverized coal technology which has been operationally and economically optimized for the past half-century. This comparison is intended to be indicative of whether further development of the AFB concept as a viable alternative to the PC/FGD concept for electric-power generation is merited. In the second part, the load-following capability of a once-through subcritical atmospheric fluidized bed boiler is analyzed. Digital computer simulation predictions of the plant's response to open loop step changes in firing rate, feedwater flow, governor valve, unit load demand, etc, are made. The predicted response of throttle pressure, steam temperature, unit load, etc, are compared to the response of a conventional coal-fired, once-through, subcritical unit. The load-following capability is assessed through this qualitative comparison. Additional model response predictions are also presented for which no test data are presently available.

Technical notes for the conceptual design for an atmospheric fluidized-bed direct combustion power generating plant

Not Available April 1978

The processes involved, achievements in, and current state-of-the-art of the atmospheric fluidized bed (AFB) combustion technology and its application to the generation of electric power are reviewed. The information is intended to be of primary use to the manager rather than to the practicing engineer. Information is included on: fluidized bed combustion technology; sorbent regeneration; and development requirements.

The report covers the conceptual design of a 570 Mwe electric generating plant utilizing an atmospheric fluidized bed (AFB) boiler, its comparison with a 570 Mwe pulverized coal-fired plant equipped with a wet limestone flue gas desulfurization, and the preliminary definition of an AFB demonstration plant.

Norton, R.C. September 1977

Progress is reported in developing a conceptual design for a commercial size (560 MW) complete power generating station, incorporating an atmospheric fluidized combustion boiler. This design is to be developed as a variation of a base which is an established plant design with conventional pulverized coal suspension fired boiler with associated facilities. The activities of this second quarter have concerned the design of the corresponding AFB combustion power plant incorporating the individual AFB designs of the two boiler manufacturers, Babcock and Wilcox and Foster Wheeler.
