Problems solved by technology

[0016] The above-mentioned deposits lead to the work of removing the deposits, or the life of high-temperature parts is shortened due to deposits, so there is a problem that the time required for maintenance work such as deposit removal or high-temperature parts replacement increases.
Such an increase in the downtime of the equipment will cause the availability of the BFG incineration gas turbine equipment to decrease, so it is not preferable for the economical efficiency of the equipment, and therefore, measures to reduce the deposit are desired.

Embodiment Construction

[0049] Hereinafter, an embodiment of the gas turbine plant of the present invention will be described based on the drawings.

[0050] figure 1 The gas turbine facility of the illustrated embodiment is a BFG incineration gas turbine facility that operates by using ironworks by-product gas (BFG) produced in large quantities in the ironmaking process as fuel, and the output of the gas turbine 10 is used for power generation of the generator. drive etc.

[0051]The illustrated gas turbine plant operates by supplying fuel BFG from which dust has been removed by a dust collector 50 to the combustor 2 of the gas turbine 10 .

[0052] The gas turbine 10 is a prime mover of an internal combustion engine mainly composed of a compressor 1, a combustor 2, and a steam turbine 3. High-temperature combustion gas generated by combustion of fuel or the like rotates the steam turbine 3 to obtain rotational kinetic energy (shaft output).

[0053] The compressor 1 takes in external air and sup...

Abstract

The present invention provides a gas turbine device. Fuel is supplied to a combustor (2) of a gas turbine (10) to realize operation, the fuel is obtained by removing dust from gas fuel comprising dust and sulfur through a wet-type electric dust precipitator(50), and a flow path for leading the fuel from the wet-type electric dust precipitator(50) to the combustor (2) is a rust-proof piping (70).

Description

technical field [0001] The present invention relates to a gas turbine facility that operates using, for example, gas containing dust and sulfur components in the fuel, such as by-product gas of ironworks generated from an ironmaking process, as fuel. Background technique [0002] Conventionally, there is known a gas turbine facility that operates by-product gas (Blast Furnace Gas: BFG) generated in large quantities in the ironmaking process, that is, a BFG incinerator that operates by using BFG as fuel. Steam turbine equipment. [0003] Conventional BFG incineration gas turbine equipment such as Figure 4 As shown, a gas turbine 10 having a compressor 1 , a combustor 2 , and a steam turbine 3 as main components operates using BFG generated from a blast furnace 40 in an ironmaking process as fuel. The BFG generated in the blast furnace 40 is compressed by a gas compressor 60 and supplied to the combustor 2 after dust is removed by a wet electric precipitator (EP) 50 . A str...
