Abstract
PURPOSE: To minimize the total fuel cost of steam generating facilities while maintaining the quantity of SOx discharged in prescribed value by a system wherein the quantity of fuel oil supplied to each device is decided in consideration of purchase unit cost every each fuel oil of a steam generator.
CONSTITUTION: An arithmetic unit 12 takes in flow-rate signals 9 from the low sulfur containing fuel oil flow-rate transmitters 6 of each device and the properties of fuel and the unit cost of fuel every each fuel tank set to a fuel oil property set instrument 13 on the basis of the results of the analysis of high sulfur containing computing the quantity of heat necessary for each device from signals 16 from steam flow-rate transmitters 15 from a function (an efficiency curve) memorized in the arithmetic unit. Thus, the flow rate of the low sulfur containing fuel oil of each device is counted, and set to flow-rate controllers 8. The flow-rate controllers 8 compare set value and flow-rate signals and operate control valves 5.
