ガスタービン燃焼器に送っている。The blast furnace gas contains iron oxide dust such as FeO and Fe 2 O 2 and corrosive gas components. The fuel for the blast furnace gas-fired gas turbine is a mixture of two or more types of fuel that are by-produced from a converter or the like, and is burned up to the calorie required for combustion in the gas turbine. However, since the accelerating gas has a very low pressure, it is compressed to a high pressure by the fuel gas compressor and sent to the gas turbine combustor.

The blast furnace gas generated in the blast furnace (1) is collected by the dust collector (2) and stored in the blast furnace gas holder (3). When it is used, it is taken out of the blast furnace gas holder (3), mixed with another fuel gas in the mixer (4), and then sucked and compressed by the fuel gas compressor (6). Then, it is sent to the combustor (9) and mixed with the compressed air by the air compressor (8) of the gas turbine (7) and burned to drive the gas turbine (7).

【発明が解決しようとする課題】前記従来の高炉ガス焚
ガスタービンには次のような解決すべき課題があった。The conventional blast furnace gas-fired gas turbine has the following problems to be solved.
【０００７】１）前述したように酸化鉄の粉塵が含まれ

面に付着して性能や寿命を少なからぬ影響を与えるなど
している。1) As described above, since iron oxide dust is contained, the blast furnace gas collects dust at the outlet of the blast furnace, but it is impossible to completely remove even fine powder. Therefore, the dust that has passed through the dust collector is sucked into the fuel gas compressor (axial flow type), leaving dent marks on the blade surface and adhering to the blade surface, which considerably affects performance and life. .
【０００８】２）また燃料ガス圧縮機は、軸流式である

運転しないとサージングを起す。したがって低負荷運転

リーにバラツキが生じ、ガスタービンの回転数や負荷が
変動する。2) Further, since the fuel gas compressor is of the axial flow type, it has a wide surging region and causes surging unless it is operated at a flow rate of 50 to 60% or more. Therefore, in the case of low load operation and a small amount of fuel gas, it is necessary to operate in a range that does not cause surging and return the surplus to the intake side mother pipe, but the fuel gas does not flow through the piping and fuel gas cooler. The light and shade of the gas occur during the flow, and the calories of the mother pipe and the return pipe become different, so that the fuel calorie varies downstream of the confluence, and the rotational speed and load of the gas turbine fluctuate.

とする高炉ガス焚ガスタービンを提案するものである。In order to solve the above-mentioned conventional problems, the present inventor pressurizes a blast furnace gas discharged from a blast furnace with a fuel gas compressor and then burns it in a combustor. In the gas turbine, a dust collector provided at the inlet of the fuel gas compressor, a fuel gas return line that branches from the outlet of the fuel gas compressor and communicates with the inlet of the dust collector, and the fuel gas return line A blast furnace gas-fired gas turbine characterized by comprising a fuel gas recirculation control valve and a fuel gas cooler provided in a line.

命も延びる。As described above, in the present invention, since the dust collector is provided at the inlet of the fuel gas compressor, the fine dust powder that has passed through the dust collector at the blast furnace outlet is further collected and sucked into the fuel gas compressor. The amount of dust that is generated is very small. Therefore, dents and adhesion to the blade surface due to dust are minimal, deterioration of performance is suppressed, and life is extended.

Are homogenized. Therefore, the variation in the fuel calorie caused by the difference in the calorie between the mother pipe and the return pipe is also eliminated, and the fluctuation in the rotational speed and the load of the gas turbine due to it is eliminated, and the reliability of the blast furnace gas-fired gas turbine plant is improved.

ーが均一化する。The fuel gas compressor (6) is of an axial flow type and has a wide surging range. Therefore, when a small amount of fuel gas is required in low load operation, it is necessary to operate in a range where surging does not occur and to return surplus fuel gas to the suction side of the fuel gas compressor (6) again. Reference numeral (14) is its return line, and this line is provided with a fuel gas recirculation control valve (15) and a fuel gas cooler (16) and communicates with the dust collector (5) immediately before the inlet side. are doing. Since the volume of the dust collector (5) is sufficient to compensate for the volumes of the return pipe (14) and the suction mother pipe, the gas is mixed in the dust collector (5) and the calories are made uniform.
