摘要： PURPOSE:To obtain a high power generation efficiency with a simple system constitution even at a partial load by installing an inverter for driving auxiliary devices and controlling the rpm of a motor for driving a compressor. CONSTITUTION:Installing an inverter 90 for auxiliary devices, motors 57, 60 of circulation compressors 18, 34 of an anode 9 and a cathode 11 are controlled by the rpm. Namely, the amperage of the direct current is controlled by the auxiliary device inverter 90 and the voltage is controlled by the reformer reaction temperature, water vapor to carbon ratio, fuel cell operation pressure, or fuel utilization efficiency to supply a required current at a required voltage. Because the current conversion process is simplified from dc to ac in this way by controlling the frequency using the inverter 90 for the auxiliary devices, conversion loss is reduced. This makes it possible to simplify equipment constitution and to maintain a high power generation efficiency at a partial load.

摘要： PURPOSE:To obtain the titled device capable of preventing surging, which is a compressor to raise pressure of high-temperature air, is provided with controlling function for a cooler to make higher temperature of air fed to the compressor in low-load operation than that of air fed to the compressor in high-load operation and has enlarged low-load operation range. CONSTITUTION:In a compressor device to raise pressure of high-temperature air into high-temperature and high-pressure air, relatively high-temperature air A1 is fed to an air cooler 12 equipped with controlling function of cooling effects and subjected to heat exchange with cooling water C1 to give low- temperature air A2. Then the air is introduced to a compressor 13 to raise pressure of air set at the rear part of the cooler 12 to give high-temperature and high-pressure air A3. The temperature of the air A3 is raised by an air heater 14 depending upon use. The temperature of air introduced to the compressor 13 in low-load operation is made higher than that in high-load operation by a means to act on controlling function of the cooler 12 to carry out low-load operation smoothly.

摘要： PURPOSE:To improve efficiency of a plant by heating gasifying air supplied to a gasification furnace by the steam generated in a gasification furnace heat collecting boiler in order to raise the temperature of gasifying air to a high level, and to increase calorific value of the stem generated in the gasification furnace. CONSTITUTION:A gasification furnace 1 generates crude gas 4 by coal 2 and gasifying air 3 being supplied. And the crude gas 4, after being led to a gasification furnace heat collecting boiler 5, reaches to a gas refining device 10 through a high-temperature superheater 6 and each vaporizer 7 and 8 in order to become clean fuel gas 9. After that, the fuel gas 9 is sent to the combustor 21 of a gas turbine 20 to be combusted and drives a generator 24. In this case, steam 73 generated in a gasification furnace heat collecting boiler 5 at the exit of the high-temperature superheater 6 is sent to a gasification air heater 80, and the gasifying air 3 is heated here. By this, the temperature of the gasifying air 3 is raised to a high level, and calorific value of the crude gas 4 generated in the gasification furnace 1 is increased thereby in order to improve efficiency of a plant.

摘要： PURPOSE:To enhance plant efficiency in partial load operation by supplying auxiliary fuel for a gas turbine through a fuel anode during partial load operation. CONSTITUTION:During partial load operation, auxiliary fuel 45 to be supplied to an auxiliary combustor 43 is supplied together with fuel required for a fuel cell to a fuel cell anode 9 through a reformer reaction part 5 as fuel 1. Since the excess amount of fuel exceeding the amount required for power generating is supplied to the anode 9, unreacted fuel is increased in the gas at and outlet of the anode 9. Although fuel concentration at an inlet of the anode 9 is the same, unreacted fuel at the outlet of the anode is increased in inverse proportion to the fuel concentration, and fuel concentration in the anode 9 is increased. Therefore, cell voltage is increased and power generating efficiency is enhanced.
