Problems solved by technology
[0007] In addition, in order to effectively dehumidify the fuel gas and detect the cause of moisture-related failures, it is also desirable to perform moisture monitoring to confirm that the moisture in the fuel gas is below saturation. However, for example, the moisture in the fuel gas of a gas turbine Moisture monitoring has never been done, so I don't know the monitoring technology
Even if it is intended to use various moisture detectors such as specular reflection type, capacitor type, and resistive type known as general gas moisture detectors for moisture monitoring in fuel gas, because these detectors are mainly used to detect Detectors of moisture in the atmosphere are unsuitable for long-term reliable monitoring of toxic, flammable, and corrosive by-product gases

Fuel gas moisture monitoring apparatus (1) that has a simple and robust construction and exhibits stable monitoring capability. The fuel gas moisture monitoring apparatus (1) includes gas extraction piping (14) for sampling of an aliquot of fuel gas having been fed to fuel gas supply facilities; fuel gas thermometer (15) disposed at a region of fuel gas supply piping (5) where the fuel gas is setfor the state of steam saturation; squeezing member (16) for reducing of the pressure of gas having been sampled by the gas extraction piping (14) to substantially the same pressure as the steam saturation pressure at the temperature detected by the fuel gas thermometer (15); sample gas cooler (13) for adjusting of the temperature of the sample gas having been brought to substantially the same pressure as the steam saturation pressure to the temperature in the vicinity of the temperature detected by the fuel gas thermometer (15); and drain pot (18) fitted with a drain detector for detecting of any water condensed from the sample gas.
Description
technical field [0001] The present invention relates to a fuel gas moisture monitoring device and a moisture monitoring method. More specifically, it relates to an apparatus and method for monitoring moisture contained in fuel gas supplied to combustion equipment. Background technique [0002] In the field of iron and steel production, for example, in the case of producing pig iron by the blast furnace method, a by-product gas top gas (that is, blast furnace gas (Blast farnace gas, hereinafter abbreviated as BFG) is generated from the blast furnace. In recent years, examples of using these by-product gases as fuel gases of gas turbine power generation equipment for the purpose of energy saving and the like are increasing. In addition, new ironmaking processes other than the blast furnace ironmaking method (such as direct reduction iron methods such as FINEX and COREX) are being studied, and examples of the by-product gases generated by such new processes as fuels are being ...
