Title:
BOILER MIXED COMBUSTION CONTROL DEVICE, BOILER MIXED COMBUSTION CONTROL SYSTEM, BOILER MIXED COMBUSTION CONTROL METHOD, AND BOILER MIXED COMBUSTION CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/276117
Kind Code:
A1
Abstract:
A boiler mixed combustion control device according to a representative embodiment of the present disclosure is provided with: an economic efficiency calculation unit for calculating the operating profitability of a power generation facility from a fuel cost acquired from related information on a master fuel and a substitute fuel, and the price of electricity sold from power generation by the power generation facility; a mixed combustion rate calculation unit for calculating an operating mixed combustion rate of the master fuel and the substitute fuel when the power generation facility is operating, and calculating a target mixed combustion rate from the operating mixed combustion rate in correspondence with a profitability ratio between a target profitability calculated from a profitability or a profitability range set for the power generation facility and a calculated profitability calculated by the economic efficiency calculation unit; and, a safety monitoring unit for outputting information indicating that a mixed combustion rate is not to be increased when the profitability or the lower limit value of the profitability range is larger than the value of the calculated profitability, even when the target mixed combustion rate indicates that the mixed combustion rate is to be increased.
