摘要： PROBLEM TO BE SOLVED: To maintain long-hour recycling operation, and effectively use fuel by detecting the concentration of unreactive fuel in a recycling pipe, and controlling two opening-closing means so as to be opened and closed on the basis of this concentration. SOLUTION: A recycling pipe 17 is connected to a compressor 14. This pipe 17 branches off, and one leads to a chimney 19 through a recycling bypass valve 15, and the other leads to a flowmeter 18 and a hydrogen concentration meter 23 through a delivery valve 16 of the compressor. The meter 23 is a concentration detecting means to detect unreactive fuel. The recycling pipe 17 recycles the compressed unreactive fuel to a solid electrolyte fuel cell, and two opening-closing means 24 and 25 are arranged in the recycling pipe 17 and a recycling discharging line 26, and respectively open and close passages of the recycling pipe 17 and the line 26. Therefore, supply of the unreactive fuel to a fuel cell can be stopped simultaneously when the concentration of the compressed unreactive fuel reaches a prescribed value. Then, deflagation of the fuel cell 1 caused by the concentration can be checked, and safety can be enhanced.

摘要： PURPOSE:To carry out heating under pressure without increasing the temperature of a light-receiving vessel and without deteriorating its strength by a method wherein a porous ceramic is heated and a gas is passed therethrough to be heated, said gas being supplied at low temperatures prior to the heating and, after being passed through a space between the porous ceramic and a light-receiving vessel, heated to high temperatures under pressure. CONSTITUTION:A porous ceramic is heated by condensed solar light 36; through this porous ceramic steam and argon gas are passed and then heated to temperatures of approximately 1,000 deg.C; the heated steam is supplied to an electrolytic cell 30, where, by applying a DC voltage to a negative electrode 35 connected to a hydrogen pole 31 and a positive electrode 34 connected to an oxygen pole 32, the steam is electrolyzed, liberating hydrogen on the side of the hydrogen pole 31 and oxygen on the side of the oxygen pole 32; the oxygen thus produced is carried by argon gas supplied through a carrier gas inlet pipe 28 and discharged to the outside through an oxygen outlet pipe 33. By passing cool gases through a space between the porous ceramic 27 and a light-receiving vessel 21 of fused quartz prior to the heating of the gases, the light-receiving vessel 21 is cooled by the cool gases and kept from being heated to high temperatures.

摘要： PROBLEM TO BE SOLVED: To emit reaction gas to the outside of a system at a sufficiently low concentration without using an expensive, large-sized maintenance power source, and to maintain the internal pressure of a container at an atmospheric pressure or less. SOLUTION: A safety device is equipped with a reaction container 11 to which stock and process gas are fed from a stock feeder to provide a reaction inside, an exhauster 13 which is connected with the reaction container 11 and exhausts the gas inside the reaction container 11, an eliminator 14 which eliminates a deleterious ingredient contained in the exhaust air in the exhauster 13, an ejector 20 which is connected to the line between the reaction container 11 and exhauster 13 to dilute the exhaust air and gas from the reaction container 11, and a nitrogen feeder 25 connected with the ejector. In the normal operation, the reaction container 11 is exhausted by means of the exhauster 13, and deleterious gas is eliminated by means of the eliminator 14 to be exhausted. In the emergency operation, nitrogen is fed to the ejector 20 from the nitrogen feeder 25 to generate the negative pressure at the throat part of the ejector 20 by the flow of nitrogen, thus exhausting the reaction gas from the reaction container 11.

摘要： PURPOSE: To prevent the adhesion, solidifying and growth of slag on the inner wall of a starting combustor, in a two-stage jet stream bed gasifying furnace. CONSTITUTION: A plurality of slag dropping plates 25a, 25b, 25c are installed in up-and-down direction and circumferential direction along an outer wall refractory 24 below a starting combustor. The slag dropping plates are connected directly to air cylinder shafts 26a, 26b, 26c and slag 21, adhered to and solidified on the inner wall of the starting combustor, is collapsed partially by a shearing force due to the reciprocating motion of air cylinders 27a, 27b, 27c, installed at the outside of the wall, and is dropped into a slag box provided at the lower part of the device. The collapse of the slag through the reciprocating operation of the air cylinders or the slag dropping plates is effected by sending or discharging air into the air cylinders through three-way solenoid valves 28a, 28b, 28c while the sending or discharging air into or out of the cylinders are effected automatically with a given time interval employing timers 29a, 29b, 29c.

摘要： PURPOSE:To prevent a heat receptor from being damaged owing to thermal elongation by fixing a press flange having a hole through which the heat receptor passes and facing a heat insulation piping flange and a transparent cylindrical cover having a cup shaped upper end and a lower end including a flange and further having a lower end surface coaxially placed on a flange surface of a tower body. CONSTITUTION:A heat insulation piping 7 is coaxially disposed on the upper end of a tower body 6. A flange 7a of the heat insulation piping 7 is filled with a high temperature sealing member 36 upwardly thereof and a press flange 38 having a hole through which a heat receptor 8 passes is made to abut on the flange 7a and is tightened with a bolt 10. With the bolt 10 tightening the press flange 38 and the flange 7a, the high temperature sealing member 36 is pressed against the side of the heat receptor 8 and the flange 7a to fix both of the heat receptor 8 and the flange 7a. A cylindrical cover 9 having a flange 9a at the lower end thereof and having the cup-shaped upper end is placed at the lower end thereof and is coaxially disposed. Thereafter, a press ring 30 is placed and a ring 30 and a flange 29 are tightened with the bolt 10. Thus, the heat receptor 8 is prevented from being damaged owing to thermal elogation.

摘要： PURPOSE:To secure stabilized combustion state by a method wherein, solid contents, contained in flue gas, are collected and sent directly into a combustion furnace to throw them thereinto and burn them again. CONSTITUTION:A conveyor tube 18, connected to a mixing machine 13, is communicated with a fuel supplying tube 5. Solid contents, separated from the exhaust gas and collected by a dust collecting machine 9, are supplied to the half way of the fuel supplying tube 5 by air transportation and are sent directly into a burner 6 together with solid fuel 1, crushed by a crusher 4, then, are thrown into a boiler 7. Accordingly, it becomes unnecessary to send them into a banker 2 through a bag filter whereby a phenomenon, such as the formation of a bridge in the banker 2 by the collected solid contents or the generation of slip in the crusher, which is caused in case a roll mill type crusher is utilized especially, may be eliminated.

摘要： PURPOSE: To improve a coefficient of desulfurization and to reduce production of NOX, by a method wherein secondary air, charged in a combustion chamber at the rear part of a combustion range, is mixed with a desulfurizing agent carried by a part of a primary air to charge the mixture.
CONSTITUTION: Coal 1 is pulverized into fine particle by a coal crusher 7, and the pulverized coal, carried by a primary air fed in the coal crusher 7 through primary air passage 11 and 11a, passes through a pulverized coal feed pipe 8 and is blown in a furnace 13 through a burner 9 to ignite it for burning. Limestone 4, serving as a desulfurizing agent, is crushed into fine particle by a limestone crusher 7b and passes through primary air passages 11 and 11b to carry it by means of a primary air fed in the limestone crusher 7b. The pulverized coal, passing through a pulverized coal feed pipe 8b, is mixed with OFA passing through a combustion air OFA passage 14, and the mixture is blown in a rear part 20 in a furnace 13 through an OFA port 15. This permits improvement of a coefficient of desulfurization and enables reduction in production of SOX and NOX.
