摘要： PURPOSE:To improve the construction of an auxiliary heat-exchanger to be used for preventing the stagnation of noncondensable gas in a heat-transfer tube. CONSTITUTION:A heat-transfer tube passing through the evaporation part of a vacuum boiler-type evaporator is provided with a by-pass line branching at the upstream side of the evaporation part and joining at the downstream side. The by-pass line is passed through an auxiliary heat-exchanger placed in a condensed liquid return line extending from the evaporation part to the evaporator pot. The apparatus has the following merits. (1) It is not necessary to extend the pipe to the installation site of the auxiliary heat-exchanger in contrast with conventional apparatus to use an external fluid as a cooling medium and, accordingly, the apparatus cost and installation space can be reduced. (2) The supplying source of the external fluid and the operation cost of the source can be eliminated. (3) The thermal efficiency of the evaporator is improved by the effective utilization of the condensation heat of the steam for the evaporation of the low-temperature fluid.

摘要： PURPOSE:To remove any deterioration in heat transfer performance and stabilize a carbureted gas temperate in a heat transfer outlet as well as to reduce the extent of adfreezing on the outer surface of a heat transfer pipe by setting a heat exchanger, being set up in the point midway in a condensed water return pipe, down to a noncondensing gas removing part where noncondensing gas is concentrated. CONSTITUTION:Combustion heat in a burner 11 heats water 2 via a burner pipe 12, this water 2 boils under decompression into steam, and it is conducted into a condensing chamber 20 through a steam pipe 21, thus a liquefied natural gas fluid in a heat transfer bundle 24 raises its temperature by condensed heat transfer of the steam. In addition, the steam heat-exchanges with the cold liquefied natural gas fluid, turning to a condensate, and it returns to a boiler part 10 by way of a condensate return pipe 22. At this time, the steam containing noncondensing gas comes into contact with the heat transfer bundle 24 from the steam pipe 21, but a noncondensing gas removing part 23 consisting of the heat exchange is set up in the midway of a condensate return pipe 22, through which the noncondensing gas is able to be concentrated on the said part 23, thus the noncondensing gas is in no case stayed in a portion of the heat transfer pipe bundle 24 where heat exchange takes place mainly.

摘要： PURPOSE:To prevent the degradation of heat transfer performance by disposing a steam lead-in tube and a condensed water return tube for connecting the lower part of a condensation chamber to the lower part of a can body, between a decompression boiler part and a condensation chamber part, and protruding plural heat transfer tubes from other heat transfer tubes in the condensation chamber. CONSTITUTION:A condensation chamber part 20 separate from a decompression boiler part 10 is connected to a steam chamber in an upper space inside the boiler part 10 by a steam lead-in tube 21, and the lower part of the noncondensable gas removing part 22 of the condensation chamber part 20 is connected to the lower part of the boiler part 10 by a condensed water return tube 23 so as to place the condensation chamber part 20 in the same decompressed atmosphere as the decompression boiler part 10. Inside the chamber 20, there is provided a heat transfer tube bundle 30 with LNG flowing inside, and the part, protruding from the heat transfer tube bundle 30, of a noncondensable gas removing heat transfer tube part 31 is made into a separate chamber to form the noncondensable gas removing part 22. The generated steam is led into the condensation chamber 20 from the steam lead-in tube 21, heat-exchanged with a low-temperature fluid, and returned into the boiler chamber 10 through the condensed water return tube 23. The steam containing the noncondensable gas is brought into contact with the heat transfer tube bundle 30, but the noncondensable gas can be collected into the U-shape tube part of the noncondensable gas removing heat transfer tube part 31 longer than the heat transfer tube bundle 30.

摘要： PROBLEM TO BE SOLVED: To judge the remaining service life of an ORV until a crack occurs in a finned tube caused by accumulation of fatigue due to comparatively gradual and mechanical stress such as a bowing phenomenon occurring in association with generation of thermal stress in a long header tank. SOLUTION: Destructive inspection is performed to accurately measure how much remaining service life is left in the ORV from distortion slowly accumulated during a long period of ten years or more. At least one tube for heat exchange joined to the header tank is cut away from this tank along with a welding bead part, a welded part of the tube is bonded and fixed by putty to a fixture for testing, a vibration exciter is connected to an unbonded other end side of the tube to be tested for applying a required vibration until damage occurs in the tube near the welded part, it is counted until pressure of gas filled inside the tube reduces, and it is compared with a cycle until damage of a preset model or a predetermined fatigue occurs for measuring the remaining service life.

摘要： PURPOSE:To reduce the wear and tear of an aluminum alloy flame coating film by sequentially laminating and curing a sealing agent with permeability to the aluminum alloy flame coating film or the like and an epoxy resin or the like whose function as a sacrifice anode is not deteriorated on the surface of a heat exchanger panel made of an aluminum alloy material. CONSTITUTION:A protective film 5 on the surface of the heat exchanger panel of an open rack type carburetor includes a flame coating film 2 formed by flame coating aluminum alloy such as Al-Zn alloy on the surface 1 of a base metal made of an aluminum alloy material of the heat exchanger panel. Then, an achromatic and transparent or little pigment including a sealing agent 3 which has permeability to the flame coating alloy film 2 is applied to the film 2 and cured. Thus, pores in the flame coating film 2 are closed so that the film is integrated with the agent and strengthened. Further, a surface layer resin 4 of an epoxy resin or urethane resin is applied to the sealing agent 3 and cured so that the function of the flame coating film 2 as a sacrifice anode is not deteriorated. Thus, excellent sea-water resistance, cold resistance and abrasion resistance are obtained.

摘要： PROBLEM TO BE SOLVED: To enable continuous operation of a heat exchanger by a method wherein a high pressure water supply pipe is mounted horizontally between heat exchange panels to let the tip of a nozzle be set in the tangential direction of the supply pipe and an injection nozzle itself is turned in the direction of the outer circumference of the pipe or the pipe itself is rotated to achieve a mechanization and automation of cleaning by workers. SOLUTION: Between heat exchange panels 1, a main shaft pipe 10 longer than the width of the panel is pivoted horizontally and one end thereof is supplied with high pressure water from a high pressure pump 12 through a rotary joint 11. The tip part of an injection nozzle of an injection pipe 13 is slightly bent in the tangential direction of the pipe from the radial direction of the pipe so that the main shaft pipe 10 pivoted itself is rotated by an injecting reaction when the high pressure water is injected to be supplied. The high pressure water from the injection nozzle is injected to the surfaces of the heat exchange panels in a specified range of angle, namely, in a conical fashion. The position, especially position in height of the main shaft pipe 10 between the heat exchange panels 1 and the positions, shapes, dimensions and the like of the injection pipe 13 and the injection nozzle are properly selected to cover the most of the heat exchange panels 1 in the height direction as injection cleaning range.
