摘要： PURPOSE:To improve the efficiency of a coal gasifying power plant employing an oxygen oxidizing type coal gasifying furnace. CONSTITUTION:A gas turbine device comprises an air compressor 1, a combustor 2, a gas turbine 3, and a gas turbine generator 4. An air gas separating device 10 separates air into oxygen and nitrogen and feeds oxygen to a coal gasifying furnace 5 to perform gasification. Since even after nitrogen separated by the air separating device 10 is boosted by a nitrogen gas compressor 113, the temperature thereof is lower than the outlet temperature of the compressor 1, heat- exchange is effected by means of a turbine cooling air cooler 114. A nitrogen gas piping from a fuel gas feed pipe 112 and the air separating device 10 is joined in a position before the combustor 2, nitrogen gas from the air separating device 10 is also fed to the combustor 2. This constitution reduces a gas turbine cooling air temperature and reduces a cooling air amount, whereby the efficiency of a coal gasifying power plant employing an oxygen oxidizing system coal gasifying furnace can be improved.

摘要： PURPOSE:To improve heat transmission and to make the title fuel reformer compact by providing a catalyst supporting material to press the reforming catalyst on the wall surface of a reaction tube in the reformer wherein the catalyst is held on the wall surface of the reaction tube. CONSTITUTION:The reforming catalyst 9 is held on the wall surface of the reaction tube 1 in the fuel reformer. The catalyst supporting material 10 (e.g., stainless steel wool) to press the catalyst 9 on the wall surface of the reaction tube 1 is provided. As a result, the catalyst can be stably held irrespective of a change in the operating condition and with the lapse of time, and the reliability is enhanced. In addition, since the catalyst supporting material has many points of contact with the catalyst, the flow of a fluid reactant is disturbed by the points of contact, hence the heat transmission can be improved, the heat efficiency is increased, and the reformer can be made compact.

摘要： PURPOSE:To realize a system in accordance with the request of a user by applying the experience of the user for control of the system against the exclusive use of the system. CONSTITUTION:An inference means 2 receives the output of a system 4 consisting of a system equipment and a controller as well as an instruction given from outside 3 and outputs the result of inference to the system 4. Furthermore the means 2 delivers the result of inference to a knowledge base 1 by an instruction and selects the rules according to the processing contents to perform the inference processing. The input received from a plant and the data base in the base 1 are used for the answer to the inference. When a rule using a simulator 6 in the base 1 is selected, the means 2 actuates the simulator 6 to use the result of simulation to the inference and to deliver this result to the system 4. The base 1 can be produced based on the experience of a user, the knowhow, etc., and therefore applied suitably to the exclusive use. Thus the user can easily form a rule base in the system 4.

摘要： PURPOSE:To prevent the dissipation of heat to the open air and to reduce the thickness of a heat insulating layer, by providing a combustion gas flow passage and an air flow passage between the flow passage of combustion gas generated and the open air and providing a flow passage between the air flow passage and a combustion apparatus. CONSTITUTION:Raw fuel to be reformed such as methane and steam are mixed to be supplied from a supply pipe 4 and introduced into a reaction tube. The raw fuel passes through the reforming catalyst 3 provided in the inner cylinder 1 and outer cylinder 2 of the reaction tube and, at the same time, receives heat from the combustion gas flowing outside the outer cylinder of the reaction tube to generate reforming reaction being endothermic reaction. The raw fuel passing through the reforming catalyst 3 flows through the inner cylinder 1 of the reaction tube to be discharged out of the reforming device from a discharge pipe 5. Air flows through a flow passage 15 and, at the same time, cools a flow passage guide 11 to rise in its temp. The air leaving the flow passage 15 flows through the space between the flow passage guide 11 and the container 10 in the reforming device to also cool said container 10.

摘要： PURPOSE:To enhance heat transfer capacity near to the tubular wall of a reaction tube by introducing reactive gas into a reactor wherein a reforming catalyst is packed and also the reforming catalyst is held to the surface of the tubular wall, and converting reactive gas into reformed gas. CONSTITUTION:Reactive gas 11 such as a gaseous mixture of i.e. hydrocarbon and steam is fed in a reaction tube 1 via a conduit 3. Since comparatively large endothermic reaction is caused in the reaction tube, the part packed with reforming catalytic particles 9 is heated by a heated catalyst 13 from the outside of the reaction tube 1 to maintain it at 800 deg.C temp. After the reactive gas 11 being the gaseous mixture is introduced into the reaction tube 1 through the conduit 3, reforming reaction is caused in the packed layer of the reforming catalytic particles 9 and on the surface of a reforming catalyst 10 stuck on the surface of the inner wall of the reaction tube 1 and in the inside thereof to reform it to hydrogen-enriched gas.

摘要： PURPOSE:To constitute a highly reliable fuel cell generation system by making a reformed gas supplied to the anode of the fuel cell free from minute catalyst particles contained in the fuel-reforming device. CONSTITUTION:The temperature of the fuel and steam is increased by feeding a high temperature fluid through a heating medium pipe 13 which passes through a heat exchanger 14 and by feeding the fuel and steam respectively through a fuel pipe 12 and a steam pipe 13 introduced into the heat exchanger 14. In the heat exchanger 14, the temperature of the fuel and steam is increased while they are mixed together. During this process, the flow rate of steam is higher than (for example 1.5-2 times) that during the rated operation of the fuel- reforming device. When the temperature of the catalyst in the reaction tube 4 is increased by the heat supplied to the reaction tube 4, the reaction gas composed of the fuel and steam flowing through the reaction tube 4 is reformed to produce a reformed gas. The reformed gas is separated into a gas 27 and a liquid 28 in a steam separator 26 and the gas 27 is discharged through an exhaust tube 29. Cleaning of the fuel-reforming device is completed when it is determined by macroscopic observation that the amount of minute catalyst particles in the liquid 28 is below the maximum allowable level.
