[First Embodiment: Gas Turbine System 100]
FIG. 1 is a diagram illustrating a gas turbine system 100 according to a first embodiment. In FIG. 1, solid arrows indicate the flow of gas and liquid.

As shown in FIG. 1, the gas turbine system 100 includes an air compressor 110, a fuel supply unit 120, a combustor 130, a turbine 140, an exhaust heat recovery boiler 150, a heating unit 160, and a liquid to be processed. Including part 170.

The suction side of the air compressor 110 is connected to an air supply source (for example, outside air). The discharge side of the air compressor 110 is connected to the combustor 130, which will be described later, through the air supply path 114. The air compressor 110 compresses air to a predetermined pressure to generate compressed air. Compressed air is supplied to the combustor 130.

The fuel supply unit 120 supplies fuel to the combustor 130. The fuel is, for example, a gas fuel such as natural gas or hydrogen, or a liquid fuel such as heavy oil. Here, the case where the fuel is a gaseous fuel will be taken as an example. In the present embodiment, the fuel supply unit 120 includes a fuel compressor 122 and a fuel cooler 124. The suction side of the fuel compressor 122 is connected to the fuel supply source through the fuel suction pipe 122a. The discharge side of the fuel compressor 122 is connected to the combustor 130 through the fuel supply pipe 122b. The fuel compressor 122 compresses the fuel to a predetermined pressure to produce compressed fuel. The fuel compressor 122 is driven by a motor.

The fuel cooler 124 is provided in the fuel supply pipe 122b. The fuel cooler 124 cools the compressed fuel passing through the fuel supply pipe 122b. The fuel cooler 124 is, for example, a heat exchanger that exchanges heat between compressed fuel and cooling water. The cooled compressed fuel is supplied to the combustor 130 through the fuel supply pipe 122b.

The combustor 130 uses oxygen contained in compressed air to burn a compressed fuel and a combustible substance described later to generate a combustion gas. The combustion gas generated by the combustor 130 is supplied to the turbine 140 through the combustion gas supply path 132.

The turbine 140 is connected to the combustor 130 through the combustion gas supply path 132. The turbine 140 converts the combustion gas supplied from the combustor 130 into rotational power. In this embodiment, the turbine 140 is coaxially connected to the air compressor 110 and the generator 142. Therefore, the rotational power (output) generated by the turbine 140 is transmitted to the air compressor 110 and the generator 142. The air compressor 110 and the generator 142 are driven by the rotational power of the turbine 140.

The combustion gas exhaust passage 144 is connected to the turbine 140. The combustion gas after the power is recovered by the turbine 140 is exhausted to the outside through the combustion gas exhaust passage 144.

The exhaust heat recovery steam generator (HRSG) 150 is provided in the combustion gas exhaust passage 144. The exhaust heat recovery boiler 150 recovers the heat of the combustion gas exhausted from the turbine 140 to generate steam. In the present embodiment, the exhaust heat recovery boiler 150 is a heat exchanger that exchanges heat between combustion gas and water. The steam generated by the exhaust heat recovery boiler 150 is supplied to the steam utilization equipment of the factory where the gas turbine system 100 is installed.

The heating unit 160 heats the liquid to be treated. In the present embodiment, the heating unit 160 includes a first heat exchanger 162. The first heat exchanger 162 is provided on the downstream side of the exhaust heat recovery boiler 150 in the combustion gas exhaust passage 144. The first heat exchanger 162 exchanges heat between the combustion gas (for example, about 150 ° C.) that has passed through the exhaust heat recovery boiler 150 and the liquid to be treated. In the present embodiment, the liquid to be treated contains water and ammonia (flammable substance). That is, the liquid to be treated is aqueous ammonia. The liquid to be treated may be, for example, waste liquid generated in a factory where the gas turbine system 100 is installed.

The liquid to be treated unit 170 supplies the liquid to be treated to the combustor 130. In the present embodiment, the liquid to be treated unit 170 includes a tank 172, a pump 174, and a liquid to be treated pipe 176. The tank 172 stores the liquid to be treated. The suction side of the pump 174 is connected to the tank 172 through the connecting pipe 172a. The discharge side of the pump 174 is connected to the first heat exchanger 162 through the connecting pipe 174a. The liquid supply pipe 176 to be processed connects the first heat exchanger 162 and the combustor 130.

When the pump 174 is driven, the liquid to be treated stored in the tank 172 is supplied to the combustor 130 after passing through the first heat exchanger 162. That is, the liquid to be treated unit 170 supplies the liquid to be treated heated by the heating unit 160 to the combustor 130. Further, in the present embodiment, the heating unit 160 (first heat exchanger 162) vaporizes the liquid to be treated to generate a mixed gas containing water vapor and ammonia gas. Therefore, the liquid to be processed supply unit 170 supplies the mixed gas to the combustor 130.

As described above, the gas turbine system 100 according to the present embodiment includes a combustor 130 and a liquid to be treated 170. As a result, the combustor 130 can supply the combustion gas derived from the liquid to be treated and steam to the turbine 140 in addition to the combustion gas derived from the fuel.

When increasing the output of the turbine 140, the amount of fuel supplied to the combustor 130 is increased to increase the flow rate of the combustion gas supplied to the turbine 140. At this time, the temperatures of the combustor 130 and the turbine 140 rise as the fuel increases.

Therefore, in the prior art without the liquid to be supplied unit 170, the fuel can be increased only up to the heat resistant temperature of the combustor 130 and the turbine 140. That is, in the prior art, the output of the turbine 140 can be increased only up to the upper limit value Qmax of the fuel supply amount determined based on the heat resistant temperature of the combustor 130 and the turbine 140.

On the other hand, the gas turbine system 100 of the present embodiment can supply the combustion gas derived from the liquid to be treated and steam to the turbine 140 in addition to the combustion gas derived from the fuel. Therefore, when the output of the turbine 140 is about the same as that of the conventional technique, the gas turbine system 100 can reduce the fuel supply amount as compared with the conventional technique. As a result, the gas turbine system 100 can improve the power generation end efficiency as compared with the conventional technique. Further, the gas turbine system 100 can suppress the temperature rise of the combustor 130 and the turbine 140.

Further, when the calorific value obtained by burning the ammonia in the liquid to be treated is equal to or less than the calorific value required to raise the temperature of the mixed gas to the same temperature as the combustion gas derived from the fuel, the gas turbine system 100 determines. It is possible to lower the temperature of the combustor 130 and the turbine 140 to increase the output of the turbine 140 by the amount of the combustion gas and steam of ammonia. Further, when the fuel is supplied up to the upper limit value Qmax, the gas turbine system 100 does not raise the temperature of the combustor 130 and the turbine 140 as compared with the prior art, and the maximum output of the turbine 140, that is, the power generation output. It is possible to increase the maximum value of.

When the calorific value obtained by burning ammonia in the liquid to be treated exceeds the calorific value required to raise the temperature of the mixed gas to the same temperature as the combustion gas derived from the fuel, the temperature of the mixed gas rises with ammonia. The calorific value obtained by the combustion of the gas is deprived. Therefore, the gas turbine system 100 can increase the output of the turbine 140 by the amount of the combustion gas and steam of ammonia while lowering the temperatures of the combustor 130 and the turbine 140 as compared with the prior art.

Further, as described above, the liquid to be treated supply unit 170 supplies ammonia as a combustible substance to the combustor 130. By burning the ammonia in the combustor 130, energy can be recovered from the ammonia while detoxifying the ammonia. Further, as described above, when the liquid to be treated is a waste liquid, the gas turbine system 100 can reduce the cost required for treating the waste liquid.

Further, as described above, the gas turbine system 100 includes a first heat exchanger 162. As a result, the first heat exchanger 162 can turn the liquid to be treated into a mixed gas by using unused energy. As a result, the first heat exchanger 162 can reduce the cost required for heating the liquid to be treated.

In addition, ammonia has a low calorific value (for example, about half of natural gas) and a low combustion rate (for example, about 1/5 of natural gas). Therefore, as described above, the first heat exchanger 162 vaporizes the liquid to be treated. As a result, the first heat exchanger 162 can easily burn ammonia in the combustor 130 as compared with the case where the liquid to be treated is supplied to the combustor 130 as a liquid. Specifically, when the liquid to be treated is supplied to the combustor 130 as a liquid, in the combustor 130, the temperature of the liquid to be treated rises → vaporization of the liquid to be treated → the temperature rise of the mixed gas → combustion of ammonia → combustion of ammonia. The event of temperature rise of combustion gas and water vapor occurs in this order. At this time, in the temperature rise of the liquid to be treated and the vaporization of the liquid to be treated, the liquid to be treated takes heat of the atmosphere in the combustor 130. Therefore, in the combustor 130, the temperature of ammonia may drop and the ammonia may not burn. Therefore, the first heat exchanger 162 is provided, and the liquid to be processed supply unit 170 supplies the mixed gas to the combustor 130, so that the gas of ammonia can be supplied to the combustor 130. Therefore, the combustor 130 can easily burn ammonia.

Further, in the present embodiment, the connection pipe 174a of the liquid to be treated unit 170 connects the discharge side of the pump 174 and the first heat exchanger 262.

The gas turbine system 200 is configured when there is no demand for steam, and since heat is exchanged between the combustion gas having a higher temperature than the gas turbine system 100 and the liquid to be treated, the mixed gas can be heated to a higher temperature. , It becomes possible to improve the combustibility of combustible substances.
