摘要： PURPOSE:To contrive to make the electric power plant compact by constructing the fundamental base in which several fuel cells can be installed as a block so as not to expose the common piping of the fuel gas and the exhaust gas to the outside environment. CONSTITUTION:The fundamental base 2 in which several fuel cells can be installed is constructed with three rooms of the connection piping room 4, the low temperature room 5, and the high temperature room 6 like a box. In the low temperature room 5 the common supply piping 7, 8 of the fuel gas for the anode and the cathode, in the high temperature room 6 the common exhaust gas piping 9, 10, and in the connection piping room 4 the all kinds of piping for connection of the cell 1 to the piping 7-10 are installed respectively. And on the inside of each room 4-6 the common thermal insulator device 11 is provided to prevent the deterioration of the efficiency due to the heat radiation. After fixing the cell 1 on the upper surface the construction of the base is completed by performing the piping. Therefore the power plant of the fuel cell can be made compact and also the work such as installation can be simplified.

摘要： PURPOSE:To make a starting equipment compact, reduce facility cost, and decrease power loss by arranging a combustion chamber in which purified gas is burned, and supply combustion gas to a gas turbine. CONSTITUTION:Gas is purified in a gas purification unit C, and part of purified gas is passed through a bypass value to control its temperature and the other purified gas 17 is supplied to a combustion chamber 40 through a bypass control valve 19. Air for combustion is supplied to the combustion chamber 40 through an air bypass line 41 and an air bypass valve 57. The purified gas supplied to the combustion chamber 40 is burned to form a high temperature and high pressure gas and operates a gas turbine 43 and drives a compressor 46. Thereby, a starting procedure is simplified and storage tanks of heating gas for fuel cell are eliminated. The consumption of fuel for heating is reduced and facility cost for starting equipment is decreased and running cost of starting operation is also decreased.

摘要： PURPOSE:To make the dismantling work of the lid for water chamber safe and shorten a time spent for the work by a method wherein a traveling device, equipped with a hanging fitment, is mounted on a guide rail while a wheel supporting device is attached to a hole for a clamping bolt. CONSTITUTION:The traveling device 12, equipped with a hanging fitment, is mounted on the guide rail 11 attached to a rest 1 and is arranged at the center part of the lid 4 for water chamber. A wire rope 9 is connected to the handing fitment 24 attached to the upper part of the lid 4 for water chamber and the slack of the rope is tightened. A guide plate 14, having the same angle as the installing angle of the lid 4, is attached to the beam 13 of building, which is below the lid 4, in parallel to the guide rail 11. Bolt 21 and nut 22 are removed, the lid 4 is afloated in parallel by a releasing bolt and the wheel supporting device 15, equipped with a wheel 17, is attached to the hole 23 for bolt below the lid 4. The wheel 17 is abutted against the guide plate 14 and the lid 4 is hung by the traveling device 12, thereafter, the lid 4 is moved along the upper guide rail 11 and the lower guide plate 14 to the front of neighboring water chamber. Thus, the operation of hanging the lid 4 in air and the converting work of the same are not necessitated, therefore, the dismantling work becomes safe and a time necessary therefor may be shortened.

摘要： PURPOSE:To effectively utilize all of reaction tubes by operating the same under a proper condition and to miniaturize the titled apparatus while enhancing response, by providing a combustion gas guide tube surrounding each reaction tube at every one reaction tube. CONSTITUTION:Reaction gas is sent into each reaction tube 4 by piping and the formed gas is taken out from piping. The combustion gas from a combustion part 5 flows around each reaction tube to be exhausted from piping 6. Because a combustion gas guide tube 17 is provided at every reaction tube, combustion gas flows through the space 18 structually formed by the guid tubes and the reaction tubes and heat is equally supplied to all of the reaction tubes. Further, this apparatus can be constituted so as to allow combustion gas to flow only through the guide tubes by providing blocking walls to spaces 20, 21 and the supply capacity of heat to the reaction tubes can be also still more enhanced by locating each combustion part directly under each reaction tube.
