摘要： PURPOSE:To unify the thermal expansion of a tank structure, by having stored water of a normal temperature up to an appropriate level in a hot water tank, and gradually pouring hot water to store into the stored water of a normal temperature. CONSTITUTION:When a hot water is stored in a hot water tank 1, firstly, a flow of water of a normal temperature is given by opening a switching valve 5 and closing 5a; after the water of a normal temperature 3 has been stored up to an appropriate level, a hot water is poured in by closing 5 and opening 5a; thus the temperature of the stored fluid is gradually raised to unify the thermal expansion of the tank structure. For this temperature raising method, a hot water mixing equipment is not necessary; since the simplification of the equipment can be promoted, an economical effect, such as reduction of the construction cost, etc., or an excellent effect of converting an existent tank into a hot water tank easily, can be obtained.

摘要： PURPOSE: To increase the output of a heating apparatus and reduce sizes thereof by disposing in an intermediate portion of a pipe or a duct for supplying gas to be heated a fiber sintered mat, which has a circular cylinder shape formed conformingly to the shape of the piping or the duct, so as to arrange a combustion means having a combustion face on an inner surface. CONSTITUTION: Premixed gas (B) fed through a pipe 1 passes between an outer shell 2 and a baffle 3 and is supplied to a cooling portion 4 comprising a mounting member 6b at both ends of a circular cylindrical fiber mat 7 so as to cool the mounting member 6b and the premixed gas (B) is preheated. The preheated premixed gas (B) flows between the baffle 3 and the fiber mat 7 and is made under the static pressure to pass through clearance in the mat 7 and reaches an inner surface of the circular cylinder which constituted a combustion surface. At this moment, the premixed gas (B) is made to burn and combustion is completed on the surface of the fiber mat 7 before high temperature combustion gas is ejected into gas to be heated. Because the fiber mat 7 can carry out combustion of the premixed gas at a high intensity on the surface thereof, a high output of the burner 20 can be obtained.

摘要： PURPOSE:To raise tracking accuracy by calculating a diameter of a coil to be wound, from measured values of a speed, thickness, etc. in case the tail end part of a rolling material passes through the final rolling stand, and presetting this calculated value to a preset counter every time. CONSTITUTION:A speed, thickness and a roll diameter of a rolling material 3 in case the tail end part of the rolling material 3 passes through a final rolling stand 1 are measured by use of a thickness meter 12, etc. Basing on this measured value, a diameter of a coil wound to a mandrel 6 in this case is calculated. Subsequently, the calculated value of the coil diameter is preset to a preset counter 11 every time until the tail end part of the rolling material 3 passes through the final stand 1 and winding of the rolling material 3 to the mandrel 6 is completed.

摘要： PROBLEM TO BE SOLVED: To improve heat efficiency and flame holding effect, and reduce utility for cooling and hence simplify an apparatus and reduce the cost by providing a passage for supplying premixed gas of a gas fuel along a mounting member for fixing a combustion surface, and cooling a flange for pressing a burner outer shell and a combustion mat. SOLUTION: A fiber sintered mat 7, i.e., a fiber mat is fixed with a flange 5 of a burner body and a mat press flange 6 outside the burner. Premixed gas of air and fuel gas is introduced through a supply pipe 1, and is supplied to a cooling passage 4 of a mat holding flange part after passage between an outer shell 2 and a baffleplate 3, and further strikes the flange 5 and the mat holding flange 6 to cool those members while being preheated. The premixed gas flows between the baffleplate and the fiber mat 7 and passes through a gap in the fiber mat 7 with static pressure, and reaches a combustion surface 7a. The premixed bas is there combusted and completes the combustion on the surface of the fiber mat for injection as high temperature gas.

摘要： PROBLEM TO BE SOLVED: To provide a power source system capable of always operation a hybrid power generation system with high efficiency and to provide an operation method for the power source system. SOLUTION: The sum of power generation quantity of an SOFC and that of a power generator is controlled to a power generation quantity giving maximum power generation efficiency of the hybrid system constructed of them according to a command from an optimization operation system. In a direct current line, a vanadium redox-flow cell is connected. In receipt of the command from the optimization operation system, if electric power quantity required by a power system exceeds a basic electric power, the vanadium redox-flow cell carries out feeding control for discharging electric power equivalent to the shortage toward the direct current line. If the basic electric power exceeds the electric power quantity required by the power system, feeding control carried out so that surplus electric power is received from the direct current line to be accumulated.

摘要： PURPOSE:To surely prevent a stress-corrosion-crack of a tank and pipes etc., due to dissolved oxygen gas in high temperature water, by preventing oxygen gas in the air from dissolving into a high temperature water by means of feeding the previously deaerated high temperature water to a tank which is covered by a floating roof on the water in the tank. CONSTITUTION:High temperature water 2 with less dissolved oxygen by previous deaeration is fed into a tank 1 through a conduit pipe 6. Consequently the high temperature water 2 level rises in the tank 1, then the air corresponding to the raised water level according to the fed volume is discharged through a vent-pipe 5 in the air. The high temperature water 2 level lowers in the tank 1 as the water is discharged through a delivery pipe 7. Consequently the air corresponding to the lowered water level according to the delivered volume flows in the tank 1 through the vent-pipe 5. As the high temperature water 2 surface in the tank 1 is covered P by a floating roof 8, oxygen gas dissolved in the high temperature water does not almost increase. Therefore, stress- corrosion-cracks of the tank and pipes etc., due to the dissolved oxygen are surely prevented.
