摘要： PURPOSE:To restrict an increasing of occurrence of NOx, provide a stable characteristic of flame and improve a power generating efficiency by a method wherein a combustion flame within a combustion chamber and/or a wall of the combustion chamber is provided with a heat transfer surface of a heat exchanger with supplied air for a combustion device other than combustion air acting as cooling fluid for use in cooling the wall. CONSTITUTION:An air-cooled heat exchanger 4 is installed within a gas turbine combustion device 1. Air supplied from a compressor 2 to the combustion device 1, is distributed into combustion air for getting a stable combustion under an appropriate air ratio in its function and other excessive air (corresponding to air cooling a wall of a prior art gas turbine or diluted air) and its ratio is about 55:45. This diluted air may act as cooling fluid for cooling the combustion flame and restricting a thermal NOx. The air of which temperature shows a high value is mixed with combustion discharged gas at a rear part of the combustion device 1, becomes a desired TIT and is fed into a turbine 3. Fine tubes with diameter of about 3mm are applied in the heat exchanger 4.

摘要： PURPOSE:To form a thin film of annular flame at an outer periphery of a front plate by a method wherein a rear plate is arranged at an outer circumference near an extreme end of an inner tube, several secondary air injection holes are radially arranged in the rear plate and the front plate is arranged at an extreme end of the inner tube. CONSTITUTION:A rear plate 2 is arranged at an outer circumference near an extreme end of an inner tube 1, and several secondary air injection holes 3 are radially arranged. An combustion air is fed into a secondary air flow passage 10, a part of it is fed into the inner tube 1 through primary air injection holes 7. In turn, since combustion gas is being injected from gas injection holes 6, gas and primary air are being mixed and reach an extreme end of the inner tube 1 and injected from mixed gas injection holes 5. During this period, other portions of the secondary air is flowed in the secondary air flow passage 10, reach the secondary air injection holes 3 and then injected from there. A part of the secondary air strikes against the front plate 4 to form a limitless number of small eddy flows over an entire rear area of the front plate 4. Mixed gas is injected from the mixed gas injection holes 5 into the small eddy currents.

摘要： PURPOSE:To generate the steam of specified dryness by furnishing plural spouting pipes to the bottom of a horizontal cylinder provided above a mixed phase unit to be connected with it and fixing a baffle plate horizontally near the longitudinal central axis of the horizontal cylinder. CONSTITUTION:The horizontal cylinder 3 is provided above the mixed the phase unit 1 in which mixed matter of vapor and liquid is allowed to flow, and plural spouting pipes 2-2' are provided to the bottom of the horizontal cylinder 3 to form spouting passages of the mixed matter of vapor and liquid and to be connected with the mixed phase unit 1, and the baffle plate 7 is horizontally fixed near the longitudinal central axis of the horizontal cylinder 3. The area ratio of the area of the space 11 between the end part 6' of baffle plate and the end plate 5' of horizontal cylinder to the total cross-sectional inner area of the spouting pipes 2-2' is specified to 150-200, defining the total cross-sectional inner area of the spouting pipes to be 100, and the area ratio of the area of vertical height between the upper surface of the baffle plate 7 and the inner surface 3' of horizontal cylinder to the total area of the plural spouting pipes is specified to 70-150. One end or both ends of the baffle plate above a part of the spouting pipes is/are eliminated. Thus, the steam of specified dryness is obtained.

摘要： PURPOSE:To maintain the pressure and temperature of a boiler out of operation at certain values in safety for providing ease of quick steam generation by supplying the boiler water of a boiler in operation to the lower portion of the boiler water in the boiler out of operation and returning the boiler water form the boiler out of operation to the boiler in operation. CONSTITUTION:Boiler main bodies 1 and 1' are connected with each other by connecting pipes 5 and 5', a valve 5'', pipes 6 and 6' and a valve 6''. In case the boiler 1 is shut down for a short time period, or prepared for re-start after a long term shut-down, valves 5'' and 6'' are opened. A portion of saturated water is supplied underwater in the boiler main body 1 out of operation from the boiler main body 1' through the pipe 5', the valve 5'' and the pipe 5, and the water in the boiler 1 that is rather cold and has a larger density is returned to the boiler 1' in operation through the pipe 6, the valve 6'' and the pipe 6'. The water in the boiler 1 is heated by the saturated water supplied from the boiler 1', and the boiler water is circulated between the two boilers so that the pressure and the temperature in the boiler 1 are maintained at certain values.

摘要： PURPOSE:To make the installation space small and to facilitate the manufacture thereof, by a method wherein a cylindrical inner boiler, interior of which is partitioned by a water piping equipped with partitions having vertical fins into right and left sections, leaving a gas passageway at the end parts thereof, with both sections provided with a combustion chamber and flow-down water tubes respectively, is loaded in a cylindrical outer boiler vertically. CONSTITUTION:In a vertical cylindrical outer boiler 1, a cylindrical inner boiler 2 is vertically inserted. In the cylindrical boiler 2, a gas passageway 10 is formed at its end parts by a partitioning water tube 4 having vertical fins 11 of membrane structure, thus forming a partitioned combustion chamber 3 and a group of down- stream side water tubes 5. When fire combustion is performed in the combustion chamber 3, the flue gas generated by the combustion, flows into downstream side water tube group 5 through a gas passageway 10, passes through the water tube group 5, and is discharged from a discharge port 7. Further, only over the all area at the lower part interior surface of the combustion chamber 3, a refractory material 8 is provided, or on the lower part outside surface, stud-fins are attached, and thereby the lower surface of the inner surface 2 as a whole is kept horizontal. By the above constitution, the installation area is made small, and its manufacture is facilitated.

摘要： PURPOSE:To increase the efficiency of a vertical boiler, miniaturize the vertical boiler and suppress the generation of NOx by arranging many heat absorbing water tubes in a combustion chamber. CONSTITUTION:Heat absorbing water tubes 5b are closely arranged in a combustion chamber 3 in a vertical boiler inserting a vertical cylindrical inner shell 2 in a vertical cylindrical outer shell 1. For example, a gas passage 10 is left at the end thereof to stand water tubes 4 with vertical fins 8 of membrane constitution in which the combustion chamber 3 and downstream side water tube groups 5a are provided at the righthand and lefthand in the vertical cylindrical inner shell 2. Thereby a fuel gas burned by a burner 6 is burned in the combustion chamber 3 and exhausted from an outlet 7 through downstream water tube groups 5a composed of the heat absorbing tubes 5b and the water tubes 4. By such constitution, heat efficiency is heightened with low NOx generation and the boiler itself can be miniaturized by the reaction of the water tubes.
