Estimate of costs of a fluidized bed steam generating plant
Technical Report
·
OSTI ID:7089067
The costs of a steam supply plant using an atmospheric fluidized bed (AFB) boiler designed for coal firing are estimated. The estimated costs consist of capital and operating and maintenance costs for a plant with one 250,000 pounds per hour AFB boiler unit producing steam at 650 psig and 750/sup 0/F. The capital cost of this plant is very dependent on the site, application, and type of coal selected. The capital costs are about $60 to $70 per pound per hour of capacity for the single unit plant. Four unit plants can be expected to cost less, approximately $50 to $60 per pound per hour, because of the many systems which are common to all boilers. A summary of the single plant costs is provided. Operating and maintenance costs, excluding oil, were also prepared, and are tabulated. These also can vary widely, depending on the specific plant application. For this estimate, it was assumed that the steam plant would be staffed independently of adjacent process facilities.
