採用した発電プラントに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power generation plant employing a combined cycle of a phosphoric acid electrolyte fuel cell power generation device and an exhaust gas turbine power generation device.

要であり、建設工期も長期間に亘ることが多い。
また火力発電においては、燃料消費量が膨大なも
のとなり、燃焼にともなう排煙による公害問題も
付随する。 As conventional power generation facilities, facilities such as thermal power, hydropower, nuclear power, geothermal power, etc. are well known. However, these power generation systems require a vast amount of land due to the enormous amount of equipment they have, and there are limited locations where they can obtain their power source and cooling water source, so it is difficult to find a site that can meet these conditions. It was limited. Therefore, a long power transmission line is required between the power demand area and the construction period is often long.
Furthermore, in thermal power generation, the amount of fuel consumed is enormous, and there is also the problem of pollution caused by exhaust smoke that accompanies combustion.

ている。 Phosphoric acid electrolyte fuel cell power generation equipment, which has recently been developed, solves the problems caused by these conventional power generation methods, has flexibility in equipment location and equipment placement, shortens construction time, and simplifies maintenance work. This can be said to be a power generation method that does not cause pollution problems. In other words, in phosphoric acid electrolyte fuel cell power generation equipment, highly conductive anodes and cathodes are arranged on both sides of a phosphoric acid electrolyte, and hydrogen is supplied to the anode side and oxygen is supplied to the cathode side, thereby allowing electrochemical reactions to occur. This reaction oxidizes hydrogen to generate hydrogen ions, and the electrons are emitted from the external terminal to the external circuit as direct current electricity.

している状態であつた。 Hydrogen is supplied to the anode side,
Due to equipment and cost considerations, natural gas, naphtha, etc. will be used, which will be raised and supplied to the anode as hydrogen gas. It is necessary to take steps to improve the recovery rate of waste heat from this valuable fuel. On the other hand, oxygen to the cathode side is brought from the atmosphere, boosted in pressure by a turbo compressor, and then sent to the cathode side. Since this turbo compressor uses the exhaust gas from the reformer burner as a driving source, the heat recovery rate is poor during low load operation.
Moreover, the calorific value of the fuel cell itself was disposed of outside the system.

Broadly divided into fuel cell main body 1, this fuel cell main body 1
It consists of a fuel storage facility 2 for storing fuel such as LNG to be supplied to the system, a turbo compressor 3 for extracting oxygen from the atmosphere, an exhaust gas turbine 4 to which exhaust gas from the facility is guided, and a generator 5 driven by this. It is composed of a turbine power generation facility 6.

われる。 The fuel cell main body 1, which has recently been developed to have a large capacity, is constructed by disposing a highly conductive anode 8 and a cathode 9 on both sides of a phosphoric acid electrolyte 7, respectively, as shown in FIG. By supplying hydrogen to the anode 8 side and oxygen to the cathode 9 side, the following electrochemical reaction is performed on the anode 8 side.

に供給する。 Hydrogen is supplied to the anode 8 side according to the above principle, but using pure hydrogen as it is is expensive and requires a large amount of hydrogen, so a large amount of hydrogen storage equipment is required. This increases the risk of the power plant itself. Therefore, in this example,
A relatively inexpensive and easily available gas or liquid hydrocarbon-based fuel such as natural gas or naphtha is used, and this is reformed to produce hydrogen at the anode 8.

On the other hand, oxygen to the cathode 9 side of the fuel cell main body 1 is taken from the atmosphere, boosted in pressure by the turbo compressor 3, and sent through the air control valve 20. At this time, the surplus air is sent through the temperature control valve 22 for combustion in the reformer burner 21.

回収率の向上への貢献である。 One of the features of the present invention is the effective use of exhaust gas containing hydrogen that does not contribute to the reaction on the anode 8 side of the fuel cell main body 1. That is, after the moisture is removed from the exhaust gas in the separator 23, it is sent to the reformer burner 21 and burned. The exhaust gas is then led as a driving gas for the exhaust gas turbine 4 of the turbine power generation equipment 6 according to the present invention. First, the exhaust gas is sent to the exhaust mixer 24, where it is mixed with the exhaust gas containing oxygen from the cathode 9 side of the fuel cell main body 1, from which moisture has been removed by the moisture separator 25, and the temperature is increased. The exhaust gas is led to the turbine 4 via the control valve 26 and drives the generator 5. The so-called exhaust gas on the anode 8 side of the fuel cell main body 1 is effectively used as the driving gas for the exhaust gas turbine 4, thereby contributing to improving the exhaust heat recovery rate by driving the generator 5.

The cooling water heated by the heat of reaction is transferred to the steam generator 1.
4 separates steam and condensate, and the steam is sent to the reformer 16 as reforming steam. The drain from the steam generator 14 exchanges heat with external cooling water in a cooling water cooler 28 at the next stage, and then is recirculated to the fuel cell cooler 27 via a cooling water pump 29.

However, in the above power plants,
A turbo compressor 3 is used as an air supply device to the fuel cell main body 1.
Normally, the exhaust gas from the reformer burner 21 is used as a driving source for the turbo compressor 3, but in this method, the heat recovery rate is poor when the turbo compressor 3 is operated at low load.
The second feature of the present invention is that when liquid fuel such as LNG is used, the liquid fuel is transferred to the fuel tank 2.
The system employs a system in which the gas is taken out from the air, vaporized in the cooling water cooler 28, and then guided to the turbo compressor 3 via the vaporized gas control valve 32 to drive it. The vaporized gas discharged from the turbo compressor 3 is regulated by a vaporized fuel control valve 32 and sent to the fuel mixer 12. Further, the surplus of the discharged vaporized gas returns to the fuel tank 2 via the bypass valve 33. By adopting this system, the vaporized fuel gas from the fuel tank 2 is used as the driving source for the turbo compressor 3, so the turbo compressor 3 has sufficient air supply capacity for the fuel cell main body 1 from the time of startup. established in
This will improve the conventional drop in heat recovery rate during low-load operation.
