Abstract

The purpose of the present invention is to evaluate the unit price of a fuel supplied to a plant as time-series data or real-time data. This makes it possible to grasp the increment of fuel cost in time series or real time by combination with data pertaining to fuel increment that accompanies a decline in the efficiency of the constituent apparatuses of the plant. In order to achieve the aforementioned purpose, a plant monitoring system according to the present invention is characterized by being provided with: a fuel information registration unit for registering unit price information for each type of fuel; a reserve fuel management unit for managing, for each type of fuel, the supply amount of fuel supplied to the plant; and a supplied fuel calculation unit for calculating the unit priceof fuel supplied to the plant on the basis of the unit price information and the supply amount.

Description

technical field [0001] The present invention relates to a device monitoring system and a device monitoring method. In the device, the unit price of fuel provided to the device is calculated according to the received weight, the used weight, and the purchase unit price of the fuel management, and the efficiency of the constituting machine is further calculated based on the data obtained from the device. The amount of drop, thereby evaluating the loss cost due to the increase in fuel that occurs with the decrease in efficiency. Background technique [0002] Power generation equipment such as coal-fired boiler equipment degrades in efficiency over time due to dust adhering to heat transfer pipes and the like. If the efficiency is lowered, fuel will be consumed excessively, and the running cost will increase. A soot blower is installed in the boiler as a device for removing dirt from the pipe surface. The soot blower is a device that removes dust by injecting high-temperature ...
