摘要： PURPOSE:To contrive the increasing of the maximum burning quantity and the stabilizing of pulse oscillation by a method wherein an inner cylinder forming a double cylinder is structured to be the same tube diameter from the burning chamber side to the near part of an outer cylinder closed end, in a radiant tube burner provided with a burning chamber for pulse burning. CONSTITUTION:During a pulse burning operation, a burning gas produced by detonating durning in a burning chamber 32 is mainly expanded toward a tail tube corresponding part 33 side, then flowed into an annular discharging passage 34 located between an outer cylinder 1 and an inner cylinder 31 from the tail tube part corresponding part 33, further, flowed out at high speed via an exhaust chamber 26 and an exhaust pipe 27 from the discharging passage 34. In this case, as the inner cylinder 31 is structured to be the same tube diameter from the burning chamber 32 side to the tail tube part corresponding part 33, the burning gas flow rate can be increased, the increasing of the maximum burning quantity can be contrived, further, the outer cylinder 1 can be heated uniformly over whole part thereof, accordingly, the stabilzing of pulse oscillation can be achieved.

摘要： PURPOSE:To improve high temperature strength, by a method wherein a double cylinder, disposed in a heating furnace, is formed by silicone nitride ceramic. CONSTITUTION:In an outer cylinder 3 and an inner cylinder 4 of a single end type radiant tube burner 2 are formed by silicone nitride ceramic. Bending strength is increased about 2 times as high as that of a cylinder formed by silicon carbide ceramic, and the coefficient of thermal expansion is about 0.75 of that of a cylinder formed by silicone carbide ceramic. Thereby, deformation due to external stress or under its own weight and thermal deformation can be reduced, and when the outer cylinder 5 is disposed in a condition that both ends are secured, durability can be improved. Further, since thermal conductivity is increases about 1.8 time as high as that of a product formed by silicon carbide ceramic, temperature distribution of the outer cylinder 3 can be uniformized. A combustion heat is radiated from the outer cylinder 3 to the outside, and this enables improvement of thermal efficiency prevailing during heating of an object to be heated in a heating furnace 1.

摘要： PURPOSE:To prevent the base plate and backer plate of the valve mechanism part of air flap valve from the dew condensation of vapor by equipping the temperature regulation mechanism together with providing a heating body to heat the base plate and backer plate respectively. CONSTITUTION:Where the temperatures of the base plate 19 and backer plate to be detected by the temperatue detector 27, 28 are lower than the specified dew condensation preventive temperature, an electric current is sent to the heater before the pulse combustion begins, and the plate 19 and plate 20 is heated respectively. When the temperatures of 19 and 20 reach not lower than the specified dew condenstion preventive temperature, the sending of electric current to 25 and 26 is stopped. At the same time, the air for combustion and the gas for fuel are supplied in the combustion room and the pulse combustion begins. From the reasons stated above, it is not feared that the vapor, included in the combustion gas during the pulse combustion, produce the dew condensation at the base plate, the backer plate and the like of the valve mechanism part 5.

摘要： PURPOSE:To execute easily a leakage inspection by a simple device by observing a corresponding signal from an acoustic wave sensor installed in an emergency cutoff valve or its adjacent pipe, in case when a process in which the emergency cutoff valve is closed, and a gas pressure is applied to the upstream side generated. CONSTITUTION:An acoustic wave sensor (microphone) 3 is installed in an emergency cutoff valve 1 or its adjacent pipe 2. For instance, in a gas boiler in which the emergency cutoff valve 1 is a constituent element, in case when a gas pressure in an outlet of a main burner 11 rises or drops abnormally, or in case when a discharge pressure of an air blower 6 drops, and in case when a flame is extinguished, the emergency cutoff valve 1 is closed by a signal from pressure switches 12, 13, and a flame monitoring device 9, respectively. Subsequently, a gas pressure is applied to the upstream side until a main valve 5 is closed. When leakage occurs between the upstream side and the downstream side of the valve 1, a jet sound is generated, by which a signal is generated from a signal generating device 4 in accordance with a signal from the sensor 3, and whether leakage exists or not can be detected easily.

摘要： PURPOSE:To miniaturize the whole device and consequently make the installation space smaller and, in addition, contrive to improve the thermal efficiency by a structure wherein a boiler main body, which generates steam by means of a pulse burner consisting in inserting a combustion chamber and a tail pipe in the central portion of a vessel for liquid to be heated, and a decoupler, which is arranged at the upper end discharge port of the tail pipe and to the upper part of which an exhaust pipe is connected, are integrally provided. CONSTITUTION:A boiler main body 1 consists in inserting a pulse burner combustion chamber 5 and a tail pipe 6 in a long vertical cylindrical water tank 2. Because the tail pipe 6 to lead exhaust gas outside, a decoupler 7 and an exhaust pipe 10 are provided integral with the boiler body 1, the whole device is miniaturized and the installation space becomes smaller. Further, because the upper end discharge port 8 of the tail pipe 6 is penetrated in the decoupler 7 with protruded state, the sound filtering effect is enhanced and at the same time drain developed at a heat exchanger 9 for recovery of latent heat of condensation can be prevented from falling in the combustion chamber 5. Because the suction port 12 is not located opposing to the upper end discharge port 8 of the tail pipe 6, the direct sending of combustion gas into the exhaust pipe 10 can be prevented for occurring, resulting in improving the thermal efficiency of the heat exchanger 8 for the recovery of latent heat of condensation.

摘要： PURPOSE:To inspect whether a gas circuit breaker is leaked or not by emitting a sound wave from a sound wave emitter under the gas circuit breaking state and receiving the sound wave by a sound wave receiver at another side. CONSTITUTION:The sound wave emitter 3 and the sound wave receiver 4 are provided at one side and another side of an upstream side (a) or a downstream side (b) of a gas flow path 2 respectively across a gas circuit breaking part of the gas circuit breaker 1 such as gas emergency trip valve. After setting the breaker 1 to the gas circuit breaking state, the sound wave is emitted from the emitter 3, and the presence and absence of the leakage of the gas circuit breaking part is inspected by presence and absence of the received sound wave in the receiver 4. In this way, 200cc/min and 3,000cc/min leakage quantities can be detected in case 500Hz-4kHz and 40kHz sound wave frequencies respectively. Consequently, the leakage can be inspected easily by very simple machine and in a short time.
