摘要： PURPOSE:To improve response to a change in load on the system side of an evaporator being as an indirect heat exchanger for exchanging heat between a heat supplying fluid and a liq. to be evaporated by making the radiating surface substantially perpendicular. CONSTITUTION:In the evaporator 200 being the indirect heat exchanger where the heat is exchanged between the heat supplying fluid and the liq. to be evaporated, a heat source, the radiating surface 210 for radiating the heat, a heat receiving space brought into contact with the radiating surface 210 in which a liq. is evaporated and a spray 10 for injecting the liq. onto the radiating surface 210 are provided. The radiating surface 210 is made substantially perpendicular. Consequently, since the evaporator is excellent in a cold starting characteristic, the evaporator can be used for an on-site fuel cell, etc. The response to the change in the load on the system side is improved.

摘要： PURPOSE:To miniaturize a reactor, and to obtain hydrogen with low content of carbon monoxide relatively easily, by dividing a contact zone of a mixed gas of methanol and steam and a catalyst into two, bringing the gas into contact with the catalyst under specific conditions. CONSTITUTION:(i) A contact zone of a raw material gas consisting essentially of methanol vapor and steam and a catalyst is divided into two of the first contact zone 16 to bring the gas into contact with the catalyst 17 and the second contact zone 10 to bring it into contact with the catalyst 11, locating at the downstream of the zone. (ii) The temperature of the gas flowing into the first contact zone 16 is 170-500 deg.C, and the temperature of the gas flowing out of it is 250-350 deg.C. (iii) The temperature of the gas flowing into the second contact zone 10 is 200- 300 deg.C, and the temperature of the gas flowing out of it is 170-230 deg.C. The gas that is passing from the first contact zone 16 to the second contact zone 10 and the gas that is reacting in the second contact zone 10 are cooled by the counter current indirect heat change between the gas and the raw material gas. (v) A ratio of a molar fraction of steam to a molar fraction of methanol vapor at the first contact zone 16 is 1.0-2.5.

摘要： PURPOSE:To obtain reformed gas of stable composition by inputting a detection signal of flue gas in addition to a detection temperature signal of a catalytic layer to a controller while utilizing said flue gas temperature signal as an arithmetic correction factor of a burner calory regulation output signal. CONSTITUTION:A temperature detector 11 of flue gas is provided on a flue 3' of a furnace 3 in addition to the temperature detector 8 of a catalytic layer 4 while inputting these detection signals to a controller 9a for operating the temperature of flue gas as a correction factor for the temperature signal of a catalytic layer 4 while regulating an opening degree of a burner fuel feeding valve 10 by its output. When the flue gas temperature exceeds the proper value as compared with the proper value, a control signal of suppressing the opening degree of the fuel feeding valve 10 is outputted to throttle the feeding valve 10 or stop an increase in the opening degree even before the catalytic layer temperature reaches the set value. Thereby, the temperature of the catalytic layer 4 is regulated while smoothly following the set value thus to quantatively and constitutionally stabilize the reformed gas to be fed to a fuel cell FC due to the stabilized reforming and reaction temperature.

摘要： PURPOSE:To simplify the scheme of a device, and thereby make the devise small in size. CONSTITUTION:The system is equipped with a heat exchange type pre-reformer 1, an anode gas manifold 3 and with an internal reforming type fusion carbonate type fuel cell 2, and thereby allows heat exchange to take place within the heat exchange type pre-reformer 1 between exhaust gas from the internal reforming type fusion carbonate type fuel cell 2 and fuel including hydrocarbon the carbon number of which is equal to or more than 2, and light naphtha, and concurrently allows steam reforming reaction to take place in the aforesaid fuel. Electricity is thereby generated by using reformed gas thus obtained through an anode gas manifold as fuel for the aforesaid internal reforming type fuel cell. By this constitution, hydrocarbon such as butane, light hydrocarbon and the like, the carbon number of which is large, can be used as fuel while possibility for carbon precipitation is being greatly reduced. The reformed gas of hydrocarbon becomes larger in volume by far than gas produced when methane is reformed, in this case, since anode gas can be supplied to the internal reforming type fusion carbonate type fuel cell with the volumetric flow rate of anode gas increased, so that anode gas can be uniformly distributed with ease to each single cell within the cell.

摘要： PURPOSE:To cool a stack of fuel cells using hydrogen by introducing hydrogen into a reaction gas passage in an amount in excess of that which is necessary and sufficient for fuel cell to generate power. CONSTITUTION:Hydrogen gas is an efficient heat exchanging medium because of its high heat conductivity. It is convenient for use as a cooling medium because then it will not require especially strict quality control, and in the event of leakage it is readily diffused. Hydrogen gas is economic in that after use for cooling it is re-used together with fuel exhaust gas and is also used as fuel gas; so special cooling piping is not necessary. Hydrogen gas is supplied from a large hydrogen gas manufacturing device to the fuel cell cooling system through a PSA device, etc., so that its purity is heightened.

摘要： PROBLEM TO BE SOLVED: To disturb the surface of a soln. to prevent the reprecipitation of overflowing magnesium hydroxide slurry and to uniformize the property of the discharged magnesium hydroxide slurry by supplying a part of the soln. discharged from the bottom part of a double decomposition tank to the outside part in the double decomposition tank. SOLUTION: In the double decomposition tank 1, the aq. soln. consisting essentially of the magnesium sulfate sent from an oxidation tank and a desulfulizing column of a desulfulizing system is reacted with a calcium hydroxide slurry to be converted to magnesium hydroxide and gypsum dihydride. On the other hand, in a slurry tank 2, a basic calcium compd. and water are mixed to prepare calcium hydroxide slurry. Then a part of the slurry discharged from the bottom part of the double decomposition tank 1 is supplied in circulation to the upper part of the double decomposition tank 1 and also the slurry in the slurry tank 2 is supplied to the double decomposition tank 1. An agitating means is disposed in an inner cylinder 3 of the double decomposition tank 1 so that the influence of the agitation is prevented to be applied to the outside part in the double decomposition tank 1 by the inner cylinder 3.
