Description

本発明は、重質油を高温高圧水と混合して改質する燃料改質器と、この燃料改質器で生成した改質燃料を燃焼器で燃焼し、発生した燃焼ガスにより駆動するガスタービンとをそれぞれ備えた複数のガスタービン設備を有する改質燃料焚きガスタービンシステムに関する。   The present invention relates to a fuel reformer for reforming by mixing heavy oil with high-temperature and high-pressure water, and a gas driven by the generated combustion gas after the reformed fuel generated by the fuel reformer is combusted in the combustor. The present invention relates to a reformed fuel-fired gas turbine system having a plurality of gas turbine facilities each including a turbine.

一般に、ガスタービン設備は、圧縮空気を生成する圧縮機と、この圧縮機からの圧縮空気と燃料を混合燃焼する燃焼器と、この燃焼器で発生した燃焼ガスにより駆動するガスタービンと、このガスタービンの駆動によって発電する発電機とを備えている。近年、重質油を軽質化、脱硫黄化、及び脱金属化して、ガスタービンに利用可能な燃料に改質する方法が提唱されている（例えば、特許文献１参照）。燃料改質器（超臨界反応器）は、重質油の改質反応条件（例えば温度３８０℃、圧力２５ＭＰａ）で重質油と高温高圧水を混合反応させ、熱分解と加水分解を行って改質燃料を生成し、この生成した改質燃料を燃焼器に供給するようになっている。   In general, a gas turbine facility includes a compressor that generates compressed air, a combustor that mixes and burns compressed air and fuel from the compressor, a gas turbine that is driven by the combustion gas generated in the combustor, and the gas. And a generator for generating electricity by driving the turbine. In recent years, a method has been proposed in which heavy oil is lightened, desulfurized, and demetalized to be reformed into a fuel that can be used in a gas turbine (see, for example, Patent Document 1). The fuel reformer (supercritical reactor) performs the thermal decomposition and hydrolysis by mixing and reacting heavy oil and high-temperature high-pressure water under the reforming reaction conditions of heavy oil (for example, temperature 380 ° C., pressure 25 MPa). A reformed fuel is generated, and the generated reformed fuel is supplied to the combustor.

ガスタービンを複数台設け、電力需要等に応じて台数制御する方法が一般に知られている。そこで、上述した燃料改質器、燃焼器、及びガスタービン等をそれぞれ備えた複数のガスタービン設備を想定する。すなわち、これら複数のガスタービン設備のうち少なくとも１台はベース運転用として連続運転し、他のガスタービン設備は台数制御用として電力需要に応じて運転・停止制御する。ところが、このような構成において台数制御用ガスタービン発電設備を停止させる場合、燃料改質器への重質油及び高温高圧水の供給を停止すると、燃料改質器が自然放熱により常温近くまで冷却される可能性がある。そのため、台数制御用ガスタービンを再起動させるときに、重質油及び高温高圧水の供給を開始しても、燃料改質器内の温度が重質油の改質反応温度まで上昇するのに時間を要してしまう。   A method is generally known in which a plurality of gas turbines are provided and the number of gas turbines is controlled according to electric power demand or the like.

And.

台数制御用ガスタービン設備１Ｂは、ベース運転用ガスタービン設備１Ａと同様の構成であり、重質油を高温高圧水と混合して改質する燃料改質器２Ｂと、この燃料改質器２Ａで生成した改質燃料を減圧するオリフィス等の減圧器３Ｂと、減圧した改質燃料を気液分離する気液分離器４Ｂと、この気液分離器４Ｂで分離した改質ガス（気体改質燃料）又は改質油（液体改質燃料）を、圧縮機５Ｂで生成した圧縮空気とともに混合燃焼する燃焼器６Ｂと、この燃焼器６Ｂで発生した燃焼ガスにより駆動するガスタービン７Ｂと、このガスタービン７Ｂの駆動によって発電する発電機（図示せず）とを備えている。なお、ガスタービン７Ａ，７Ｂからの排熱ガス（燃焼排ガス）は、煙突８を介し大気に放出されるようになっている。   The number control gas turbine equipment 1B has the same configuration as the base operation gas turbine equipment 1A, a fuel reformer 2B for reforming by mixing heavy oil with high-temperature high-pressure water, and the fuel reformer 2A. The decompressor 3B such as an orifice for decompressing the reformed fuel generated in step 1, the gas-liquid separator 4B for separating the decompressed reformed fuel into gas and liquid, and the reformed gas (gas reforming) separated by the gas-liquid separator 4B Fuel) or reformed oil (liquid reformed fuel) together with the compressed air generated by the compressor 5B, a combustor 6B, a gas turbine 7B driven by the combustion gas generated in the combustor 6B, and the gas And a generator (not shown) that generates electricity by driving the turbine 7B. The exhaust heat gas (combustion exhaust gas) from the gas turbines 7A and 7B is released to the atmosphere via the chimney 8.

燃料改質器２Ａ，２Ｂは、例えば温度２００〜４００℃、圧力１０〜３０ＭＰａ程度の重質油と例えば３５０〜５００℃、１０〜３０ＭＰａの高温高圧水とが導入され、これら重質油及び高温高圧水を混合反応させ、重質油を軽質化した改質燃料を生成するようになっている。その際に生じた残渣油であるタールは、燃料改質器２Ａ，２Ｂの底部からタール管９Ａ，９Ｂを介し排出されるようになっている。また、燃料改質器２Ｂへの重質油及び高温高圧水の供給系統には、重質油及び高温高圧水の供給量をそれぞれ制御する流量制御弁１０，１１が設けられている。   In the fuel reformers 2A and 2B, for example, a heavy oil having a temperature of 200 to 400 ° C. and a pressure of about 10 to 30 MPa and a high-temperature high-pressure water having a temperature of 350 to 500 ° C. and 10 to 30 MPa are introduced. A reformed fuel in which heavy oil is lightened is produced by mixing and reacting with high-pressure water.

The heavy oil and high-temperature high-pressure water supply system to the fuel reformer 2B is provided with flow control valves 10 and 11 for controlling the supply amounts of heavy oil and high-temperature high-pressure water, respectively.

気液分離器４Ａは、燃料改質器２Ａで生成された改質燃料を改質ガス及び改質油に気液分離し、改質ガスを改質ガス供給系統１２Ａを介し燃焼器６Ａに導出し、改質油を改質油タンク１３に導出するようになっている。また同様に、気液分離器４Ｂは、燃料改質器２Ａで生成した改質燃料を改質ガス及び改質油に気液分離し、改質ガスを改質ガス供給系統１２Ｂを介し燃焼器６Ｂに導出し、改質油を改質油タンク１３に導出するようになっている。改質油タンク１３内の改質油は、改質油ポンプ１４によって改質油供給系統１５Ａ，１５Ｂを介し燃焼器６Ａ，６Ｂにそれぞれ供給されるようになっている。なお、改質ガス供給系統１２Ａ，１２Ｂには、改質ガスの供給量を制御する流量制御弁１６Ａ，１６Ｂがそれぞれ設けられ、改質油供給系統１５Ａ，１５Ｂには、改質油の供給量を制御する流量制御弁１７Ａ，１７Ｂがそれぞれ設けられている。   The gas-liquid separator 4A gas-liquid separates the reformed fuel generated by the fuel reformer 2A into reformed gas and reformed oil, and the reformed gas is led to the combustor 6A via the reformed gas supply system 12A. Then, the reformed oil is led out to the reformed oil tank 13. Similarly, the gas-liquid separator 4B gas-liquid separates the reformed fuel produced by the fuel reformer 2A into reformed gas and reformed oil, and the reformed gas is combusted via the reformed gas supply system 12B. 6B, the reformed oil is led out to the reformed oil tank 13. The reformed oil in the reformed oil tank 13 is supplied to the combustors 6A and 6B via the reformed oil supply systems 15A and 15B by the reformed oil pump 14, respectively. The reformed gas supply systems 12A and 12B are respectively provided with flow control valves 16A and 16B for controlling the supply amount of the reformed gas, and the reformed oil supply systems 15A and 15B are supplied with the reformed oil supply amount.

The merging system 18 is provided with a switching valve 19 that can be switched to a communication / blocking state.

次に、本実施形態による改質燃料焚きガスタービンシステムの運転方法を説明する。   Next, an operation method of the reformed fuel-fired gas turbine system according to the present embodiment will be described.

例えばベース運転用ガスタービン設備１Ａの最大出力より電力需要が大きい場合、ベース運転用ガスタービン設備１Ａ及び台数制御用ガスタービン設備１Ｂをともに運転させる。詳細には、ベース運転用ガスタービン設備１Ａにおける改質ガス供給系統１２Ａの流量制御弁１６Ａ及び改質油供給系統１５Ａの流量制御弁１７を開放し、台数制御用ガスタービン設備１Ｂにおける改質ガス供給系統１２Ｂの流量制御弁１６Ｂ及び改質油供給系統１５Ｂの流量制御弁１７を開放し、合流系統１８の切換弁１９を閉止する。そして、ベース運転用ガスタービン設備１Ａの燃料改質器２Ａに重質油及び高温高圧水を供給し、これら重質油と高温高圧水を混合反応させて改質燃料を生成し、気液分離器４Ａで改質ガスと改質油に気液分離する。改質ガス及び改質油（但し、改質燃料を生成するまでは改質油タンク１３内の改質油のみ）は、それぞれ改質ガス供給系統１２Ａ及び改質油供給系統１５Ａ等を介し燃焼器６Ａに導入され、圧縮機５Ａからの圧縮空気とともに混合燃焼される。その結果、ガスタービン７Ａが駆動して発電する。   For example, when the power demand is larger than the maximum output of the base operation gas turbine equipment 1A, both the base operation gas turbine equipment 1A and the unit control gas turbine equipment 1B are operated. Specifically, the flow rate control valve 16A of the reformed gas supply system 12A and the flow rate control valve 17 of the reformed oil supply system 15A in the gas turbine facility 1A for base operation are opened, and the reformed gas in the gas turbine facility 1B for unit control is opened. The flow control valve 16B of the supply system 12B and the flow control valve 17 of the reforming oil supply system 15B are opened, and the switching valve 19 of the merge system 18 is closed. Then, heavy oil and high-temperature high-pressure water are supplied to the fuel reformer 2A of the base operation gas turbine equipment 1A, and these heavy oil and high-temperature high-pressure water are mixed and reacted to generate reformed fuel, and gas-liquid separation Gas-liquid separation into reformed gas and reformed oil is performed in the vessel 4A. The reformed gas and reformed oil (however, until the reformed fuel is generated, only the reformed oil in the reformed oil tank 13) is combusted through the reformed gas supply system 12A, the reformed oil supply system 15A, etc., respectively. It is introduced into the vessel 6A and mixed and burned together with the compressed air from the compressor 5A. As a result, the gas turbine 7A is driven to generate power.

また、流量制御弁１０，１１を開放して台数制御用ガスタービン設備１Ｂの燃料改質器２Ｂに重質油及び高温高圧水を供給し、これら重質油と高温高圧水を混合反応させて改質燃料を生成し、気液分離器４Ｂで改質ガスと改質油に気液分離する。改質ガス及び改質油（但し、改質燃料を生成するまでは改質油タンク１３内の改質油のみ）は、それぞれ改質ガス供給系統１２Ｂ及び改質油供給系統１５Ｂを介し燃焼器６Ｂに導入され、圧縮機５Ｂからの圧縮空気とともに混合燃焼される。その結果、ガスタービン７Ｂが駆動して発電する。そして、例えば流量制御弁１６Ａ，１７Ａ又は１６Ｂ，１７Ｂを制御して燃焼器６Ａ，６Ｂへの改質ガス及び改質油の供給量をそれそれ調整することにより、ガスタービン７Ａ，７Ｂの負荷を変動させ、電力需要に応じた発電を行うことができる。   Further, the flow control valves 10 and 11 are opened to supply heavy oil and high-temperature and high-pressure water to the fuel reformer 2B of the gas turbine equipment 1B for controlling the number of units, and these heavy oil and high-temperature and high-pressure water are mixed and reacted. The reformed fuel is generated and gas-liquid separated into reformed gas and reformed oil by the gas-liquid separator 4B. The reformed gas and reformed oil (however, until the reformed fuel is generated, only the reformed oil in the reformed oil tank 13) are combusted via the reformed gas supply system 12B and the reformed oil supply system 15B, respectively. 6B and mixed and burned together with the compressed air from the compressor 5B. As a result, the gas turbine 7B is driven to generate power. Then, for example, by controlling the flow rate control valves 16A, 17A or 16B, 17B to adjust the supply amounts of the reformed gas and reformed oil to the combustors 6A, 6B, the loads on the gas turbines 7A, 7B are adjusted. It is possible to vary the power generation according to the power demand.

一方、例えばベース運転用ガスタービン設備１Ａの最大出力より電力需要が小さい場合は、台数制御用ガスタービン１Ｂを停止させる。詳細には、台数制御用ガスタービン１Ｂにおける改質ガス供給系統１２Ｂの流量制御弁１６Ｂ及び改質油供給系統１５Ｂの流量制御弁１７Ｂを閉止する。これにより、燃焼器６Ｂへの改質ガス及び改質油の供給が停止され、ガスタービン７Ｂが停止する。そして、例えばベース運転用ガスタービン設備１Ａの流量制御弁１６Ａ，１７Ａを制御して改質ガス及び改質油の供給量を調整することにより、ガスタービン７Ａの負荷を変動させ、電力需要に応じた発電を行うことができる。   On the other hand, for example, when the power demand is smaller than the maximum output of the base operation gas turbine equipment 1A, the number control gas turbine 1B is stopped. Specifically, the flow rate control valve 16B of the reformed gas supply system 12B and the flow rate control valve 17B of the reformed oil supply system 15B in the unit number control gas turbine 1B are closed. Thereby, supply of the reformed gas and reformed oil to the combustor 6B is stopped, and the gas turbine 7B is stopped. Then, for example, by controlling the flow rate control valves 16A and 17A of the gas turbine equipment 1A for base operation to adjust the supply amount of the reformed gas and the reformed oil, the load of the gas turbine 7A is fluctuated to meet the power demand. Can generate electricity.

また、台数制御用ガスタービン１Ｂの重質油供給系統の流量制御弁１０を閉止するとともに、高温高圧水供給系統の流量制御弁１１を制御して定格流量より少量（燃料改質器２Ｂを所定の温度に維持するために必要な流量）の高温高圧水を燃料改質器２Ｂに供給する。これにより、燃料改質器２Ｂを加熱して燃料改質器２Ｂ内の温度を所定の温度（例えば重質油を改質反応させる最適温度）に維持するとともに、燃料改質器２Ｂ内を洗浄することができる（コークスの除去効果も得られる）。その結果、台数制御用ガスタービン設備１Ｂを再起動する場合に、重質油供給系統の流量制御弁１０を開放し、高温高圧水供給系統の流量制御弁１１を定格流量に制御して、燃料改質器２Ｂへの重質油及び高温高圧水の供給を開始すると、重質油と高温高圧水とがすみやかに混合反応して改質燃料を生成することができる。   In addition, the flow control valve 10 of the heavy oil supply system of the gas turbine 1B for controlling the number of units is closed, and the flow control valve 11 of the high-temperature and high-pressure water supply system is controlled so that the flow rate is less than the rated flow (the fuel reformer 2B is predetermined). High temperature and high pressure water at a flow rate necessary to maintain the temperature of the fuel reformer 2B. As a result, the fuel reformer 2B is heated to maintain the temperature in the fuel reformer 2B at a predetermined temperature (for example, the optimum temperature for reforming the heavy oil), and the fuel reformer 2B is cleaned. (Coke removal effect is also obtained). As a result, when the number control gas turbine equipment 1B is restarted, the flow control valve 10 of the heavy oil supply system is opened, the flow control valve 11 of the high temperature and high pressure water supply system is controlled to the rated flow, and the fuel is supplied. When the supply of the heavy oil and the high temperature / high pressure water to the reformer 2B is started, the heavy oil and the high temperature / high pressure water can be immediately mixed and reacted to generate the reformed fuel.

以上のように本実施形態においては、連続運転するベース運転用ガスタービン設備１Ａと、運転・停止制御する台数制御用ガスタービン１Ｂとを備えた構成とすることにより、電力需要等に応じて効率よく発電することができる。また、停止中の台数制御用ガスタービン設備１Ｂの燃料改質器２Ｂ内に高温高圧水を供給することにより、自然放熱等による燃料改質器２Ｂの温度低下を抑えることができる。したがって、重質油及び高温高圧水を供給したときの改質燃料生成の立ち上げ時間を短縮することができ、台数制御用ガスタービン設備１Ｂの起動時間を短縮することができる。   As described above, in the present embodiment, the configuration includes the base operation gas turbine equipment 1A for continuous operation and the unit control gas turbine 1B for operation / stop control, so that the efficiency depends on the power demand and the like. It can generate electricity well. In addition, by supplying high-temperature high-pressure water into the fuel reformer 2B of the stopped unit number control gas turbine facility 1B, it is possible to suppress a temperature drop of the fuel reformer 2B due to natural heat dissipation or the like. Therefore, the start-up time for generating reformed fuel when supplying heavy oil and high-temperature high-pressure water can be shortened, and the start-up time of the unit control gas turbine equipment 1B can be shortened.

また、停止中の台数制御用ガスタービン設備１Ｂの燃料改質器２Ｂ内に供給された高温高圧水は、燃料改質器２Ｂ内に残留している油分や可燃ガス等の可燃成分を含むようになり、そのままでは大気に放出することができず何らかの処理が必要となる。そこで本実施形態においては、台数制御用ガスタービン設備１Ｂを停止させた場合、改質ガス供給系統１２Ｂの流量制御弁１６Ｂ及び改質油供給系統１５Ｂの流量制御弁１７Ｂを閉止し、合流系統１８の切換弁１９を開放して、燃料改質器２Ｂ内の高温高圧水（蒸気）を減圧弁３Ｂ、気液分離器４Ｂ、及び合流系統１８を経由しベース運転用ガスタービン設備１Ａの改質ガス供給系統１２Ａに合流させる。これにより、改質ガス供給系統１２Ａの改質ガスとともに高温高圧水が燃焼器６Ａに導入され、高温高圧水に含まれた可燃成分が燃焼される。したがって、専用処理装置を別途設けることなく処理することができる。また、高温高圧水を増加させたぶんだけ燃焼器６Ａで発生する燃焼ガスの流量が増加し、ガスタービン７Ａの出力を向上させることができる。   Further, the high-temperature and high-pressure water supplied into the fuel reformer 2B of the gas turbine equipment 1B for controlling the number of units that are stopped includes a combustible component such as oil and combustible gas remaining in the fuel reformer 2B. Therefore, it cannot be released into the atmosphere as it is, and some kind of treatment is required. Therefore, in the present embodiment, when the number control gas turbine equipment 1B is stopped, the flow rate control valve 16B of the reformed gas supply system 12B and the flow rate control valve 17B of the reformed oil supply system 15B are closed, and the merge system 18 The switching valve 19 is opened, and the high-temperature high-pressure water (steam) in the fuel reformer 2B is reformed through the pressure reducing valve 3B, the gas-liquid separator 4B, and the merging system 18 to reform the base operation gas turbine equipment 1A. The gas is fed to the gas supply system 12A. Thereby, the high-temperature high-pressure water is introduced into the combustor 6A together with the reformed gas of the reformed gas supply system 12A, and combustible components contained in the high-temperature high-pressure water are combusted. Therefore, it is possible to perform processing without separately providing a dedicated processing device. Further, the flow rate of the combustion gas generated in the combustor 6A increases as much as the high-temperature high-pressure water is increased, and the output of the gas turbine 7A can be improved.

本発明の第２の実施形態を図２により説明する。本実施形態は、運転中のベース運転用ガスタービン設備１Ａのガスタービン７Ａからの排熱ガスを利用して生成した蒸気を、停止中の台数制御用ガスタービン設備１Ｂの燃料改質器２Ｂに供給する実施形態である。   A second embodiment of the present invention will be described with reference to FIG.

Then, the supply of heavy oil and high-temperature high-pressure water to the fuel reformer 2B is stopped. Further, the flow control valve 25 of the steam supply system 24 is opened, and the steam (steam having a pressure lower than that of the high-temperature and high-pressure water) generated in the exhaust heat recovery boiler 20 is supplied into the fuel reformer 2B. Thus, the fuel reformer 2B can be heated to maintain the temperature inside the fuel reformer 2B at a predetermined temperature, and the inside of the fuel reformer 2B can be cleaned. As a result, when restarting the number control gas turbine equipment 1B, the flow control valve 25 of the steam supply system 24 is closed, the flow control valve 10 of the heavy oil supply system, and the flow control valve of the high-temperature high-pressure water supply system. 11 is opened, and supply of heavy oil and high-temperature high-pressure water to the fuel reformer 2B is started, the heavy oil and high-temperature high-pressure water can be immediately mixed and reacted to generate reformed fuel. .

Further, the rotational speed and load of the gas turbine 7A at the time of starting the gas turbine facility 1A for base operation, the supply amount of high-temperature high-pressure water and heavy oil to the fuel reformer 2A, and the reforming capacity of the fuel reformer 2B The change with the passage of time is substantially the same as when the gas turbine equipment 1B for controlling the number of units is started up, and therefore illustration is omitted.

最初に、ベース運転用ガスタービン設備１Ａ及び台数制御用ガスタービン設備１Ｂをともに起動させる場合について説明する。ベース運転用ガスタービン設備１Ａ及び台数制御用ガスタービン設備１Ｂにおける改質油供給系統の流量制御弁１７Ａ，１７Ｂを開放して、改質油タンク１１からの改質油を燃焼器６Ａ，６Ｂにそれぞれ供給して燃焼させ、ガスタービン７Ａ，７Ｂを駆動する。これと同時に、タールタンク２９からのタール（又は重質油タンク４４からの重質油）を燃焼炉２８に供給して燃焼させ、高温ガスを発生させる。発生した高温ガスは第１熱交換器４２及び第２熱交換器４７を経由し、燃料改質器２Ａの加熱流路３１Ａ及び燃料改質器２Ｂの加熱流路３１Ｂにそれぞれ導入され、燃料改質器２Ａ，２Ｂを外部から加熱することができる。   First, a case where both the base operation gas turbine equipment 1A and the unit control gas turbine equipment 1B are started will be described. The flow control valves 17A and 17B of the reformed oil supply system in the base operation gas turbine equipment 1A and the unit control gas turbine equipment 1B are opened, and the reformed oil from the reformed oil tank 11 is sent to the combustors 6A and 6B. Each is supplied and burned to drive the gas turbines 7A and 7B. At the same time, tar from the tar tank 29 (or heavy oil from the heavy oil tank 44) is supplied to the combustion furnace 28 and burned to generate high-temperature gas. The generated high temperature gas passes through the first heat exchanger 42 and the second heat exchanger 47, and is introduced into the heating flow path 31A of the fuel reformer 2A and the heating flow path 31B of the fuel reformer 2B, respectively. The quality devices 2A and 2B can be heated from the outside.

また、第２供給系統４６の流量制御弁４９を閉止し、分岐系統５１の流量制御弁５２を開放して、水ポンプ４０で加圧した水を第１熱交換器４２及び第２熱交換器４７に導入して加熱する。このようにして得た高温高圧水を、流量制御弁４３Ａ，４８Ａを開放して燃料改質器２Ａに供給し、また流量制御弁４３Ｂ，４８Ｂを開放して燃料改質器２Ｂに供給し（このとき、燃料改質器２Ａ，２Ｂへの高温高圧水の供給量は定格流量（１００％）を超える）、これによって燃料改質器２Ａ，２Ｂを加熱するとともに洗浄することができる。   Further, the flow control valve 49 of the second supply system 46 is closed, the flow control valve 52 of the branch system 51 is opened, and the water pressurized by the water pump 40 is supplied to the first heat exchanger 42 and the second heat exchanger. It introduce | transduces into 47 and heats. The high-temperature and high-pressure water thus obtained is supplied to the fuel reformer 2A with the flow control valves 43A and 48A open, and supplied to the fuel reformer 2B with the flow control valves 43B and 48B open ( At this time, the supply amount of the high-temperature high-pressure water to the fuel reformers 2A and 2B exceeds the rated flow rate (100%)), whereby the fuel reformers 2A and 2B can be heated and cleaned.

その後、燃料改質器２Ａ，２Ｂ内の温度が所定の温度（例えば重質油を改質反応させる最適温度）に達したら、分岐系統５１の流量制御弁５１を徐々に閉じて燃料改質器２Ａ，２Ｂへの高温高圧水の供給量を減少させ定格流量とするとともに、第２供給系統の流量制御弁４９を徐々に開いて燃料改質器２Ａ，２Ｂへの重質油の供給量を増加させて定格流量とする。このような流量制御により、熱交換器４２，４７における水及び重質油と高温ガスとのヒートバランス（熱収支）を維持しつつ、重質油の供給量を増加させることができる。そして、燃料改質器２Ａ，２Ｂ内に供給された重質油と高温高圧水とがすみやかに混合反応して改質燃料を生成することができ、生成した改質燃料（改質ガス及び改質油）を燃焼器６Ａ，６Ｂに安定して供給することができるようになる。   After that, when the temperature in the fuel reformers 2A and 2B reaches a predetermined temperature (for example, the optimum temperature for reforming the heavy oil), the flow control valve 51 of the branch system 51 is gradually closed to close the fuel reformer. While reducing the supply amount of high-temperature and high-pressure water to 2A and 2B to obtain a rated flow rate, the flow control valve 49 of the second supply system is gradually opened to reduce the supply amount of heavy oil to the fuel reformers 2A and 2B. Increase to the rated flow rate. By such flow rate control, it is possible to increase the supply amount of heavy oil while maintaining the heat balance (heat balance) of water and heavy oil and high-temperature gas in the heat exchangers 42 and 47. Then, the heavy oil supplied into the fuel reformers 2A and 2B and the high-temperature and high-pressure water can be immediately mixed and reacted to generate a reformed fuel. The generated reformed fuel (reformed gas and reformed gas) Quality oil) can be stably supplied to the combustors 6A and 6B.

台数制御用ガスタービン設備１Ｂを停止させる場合について説明する。台数制御用ガスタービン設備１Ｂにおける改質ガス供給系統１２Ｂの流量制御弁１６Ｂ及び改質油供給系統１５Ｂの流量制御弁１７Ｂを閉止して、燃焼器６Ｂへの改質ガス及び改質油の供給を停止し、ガスタービン７Ｂを停止させる。これと同時に、流量制御弁４８Ｂを閉止して燃料改質器２Ｂへの重質油の供給を停止し、流量制御弁４３Ｂを制御して燃料改質器２Ｂへの高温高圧水の供給量を増加させる（定格流量を超えた供給流量とする）。そして、燃焼炉２８に供給するタール（又は重質油）の供給量を徐々に減少させ、これに併せて流量制御弁４３Ｂを制御して燃料改質器２Ｂへの高温高圧水の供給量を定格流量より減少させる（燃料改質器２Ｂを所定の温度に維持するために必要な流量とする）。このような流量制御により、熱交換器４２，４７における水及び重質油と高温ガスとのヒートバランスを維持しつつ、高温高圧水の供給量を減少させることができる。そして、台数制御用ガスタービン設備１Ｂの燃料改質器２Ｂ内に高温高圧水を供給して、燃料改質器２Ｂ内の温度を所定の温度に維持するとともに、燃料改質器２Ｂ内を洗浄することができる。   The case where the number control gas turbine equipment 1B is stopped will be described. Supplying reformed gas and reformed oil to the combustor 6B by closing the flow rate control valve 16B of the reformed gas supply system 12B and the flow rate control valve 17B of the reformed oil supply system 15B in the gas turbine equipment 1B for controlling the number of units. Is stopped, and the gas turbine 7B is stopped. At the same time, the flow control valve 48B is closed to stop the supply of heavy oil to the fuel reformer 2B, and the flow control valve 43B is controlled to reduce the supply amount of high-temperature high-pressure water to the fuel reformer 2B. Increase (the supply flow rate exceeds the rated flow rate). Then, the supply amount of tar (or heavy oil) supplied to the combustion furnace 28 is gradually reduced, and the supply amount of the high-temperature high-pressure water to the fuel reformer 2B is controlled by controlling the flow control valve 43B. The flow rate is reduced from the rated flow rate (the flow rate necessary for maintaining the fuel reformer 2B at a predetermined temperature). With such flow rate control, it is possible to reduce the supply amount of high-temperature and high-pressure water while maintaining the heat balance between water and heavy oil and high-temperature gas in the heat exchangers 42 and 47. Then, high-temperature and high-pressure water is supplied into the fuel reformer 2B of the gas turbine equipment 1B for controlling the number of units to maintain the temperature inside the fuel reformer 2B at a predetermined temperature and clean the inside of the fuel reformer 2B. can do.

その後、台数制御用ガスタービン設備１Ｂを再起動させる場合は、燃焼炉２８に供給するタール（又は重質油）の供給量を徐々に増加させ、これに併せて流量制御弁４３Ｂを制御して高温高圧水の供給量を増加させ定格流量を超えた供給流量とする。そして、流量制御弁４８Ｂを開放して燃料改質器２Ｂへの重質油の供給を開始するするとともに、流量制御弁４３Ｂを制御して燃料改質器２Ｂへの高温高圧水の供給量を減少させ定格流量とする。このような流量制御により、熱交換器４２，４７における水及び重質油と高温ガスとのヒートバランスを維持しつつ、重質油の供給量を増加させることができる。そして、燃料改質器２Ｂ内に供給された重質油と高温高圧水とがすみやかに混合反応して改質燃料を生成することができ、生成した改質燃料（改質ガス及び改質油）を燃焼器６Ｂに安定して供給することができるようになる。   After that, when restarting the number control gas turbine equipment 1B, the supply amount of tar (or heavy oil) supplied to the combustion furnace 28 is gradually increased, and the flow control valve 43B is controlled accordingly. Increase the supply amount of high-temperature and high-pressure water so that the supply flow rate exceeds the rated flow rate. Then, the flow control valve 48B is opened to start the supply of heavy oil to the fuel reformer 2B, and the flow control valve 43B is controlled to control the supply amount of high-temperature high-pressure water to the fuel reformer 2B. Reduce to the rated flow rate. By such flow rate control, it is possible to increase the supply amount of heavy oil while maintaining the heat balance of water and heavy oil and high-temperature gas in the heat exchangers 42 and 47. Then, the heavy oil supplied into the fuel reformer 2B and the high-temperature high-pressure water can be mixed and reacted promptly to generate a reformed fuel, and the generated reformed fuel (reformed gas and reformed oil) ) Can be stably supplied to the combustor 6B.

以上のような変形例においても、上記実施形態同様の効果を得ることができる。またガスタービン設備１Ａ，１Ｂの運転・停止切換時に、熱交換器４２，４７のヒートバランスを考慮した重質油及び高温高圧水の流量制御を行うので、熱交換器４２，４７が過熱し損傷するのを防止することができる。   Even in the modified example as described above, the same effect as in the above embodiment can be obtained. In addition, when the gas turbine equipment 1A and 1B is switched between operation and stop, the flow control of heavy oil and high-temperature and high-pressure water is performed in consideration of the heat balance of the heat exchangers 42 and 47. Can be prevented.
