Abstract

A fuel reduction rate output system that calculates a fuel reduction rate affecting a fuel reduction measure, which is applied to a boiler combustion control system, wherein the fuel reduction rate output system has: a deviation determination unit that records the history of measured main steam pressures as a main steam pressure history, that calculates the deviation between the main steam pressure history and the measured main steam pressures, and that outputs the history of the main steam pressure for which the deviation is within a prescribed range as a history of control main steam pressure; a standard deviation calculation unit that calculates a standard deviation on the basis of the history of control main steam pressure output by the deviation determination unit; and a fuel reduction rate output unit that calculates a standard deviation improvement rate on the basis of the standard deviation calculated by the standard deviation calculation unit and that calculates and outputs the fuel reduction rate on the basis of a reference equation indicating the relationship between the standard deviation improvement rate and the fuel reduction rate.

Description

technical field [0001] The present invention relates to a technology for controlling the combustion of a boiler, and in particular to an effective fuel reduction rate output system, a fuel reduction rate output method, and a fuel reduction rate output program applied to calculate a fuel reduction rate obtained by improving boiler efficiency. technology. Background technique [0002] For example, when using boiler equipment to obtain energy, fuel (solid fuel such as coal, liquid fuel, or gaseous fuel) is supplied to the boiler (furnace) for combustion, and the heat is absorbed by a heat exchanger to generate steam to obtain thermal energy. The generated steam is converted from thermal energy into rotational motion by being supplied to a steam turbine, for example, and is used for power generation of a generator or the like. The amount of fuel input to the boiler is determined by the load demand (for example, power generation demand MWD (Mega Watt Demand), hereinafter, someti...
