摘要： PURPOSE:To make a clearance construction on the water chamber side small and uniform throughout the circumference of a penetrating pipe by a method wherein the cylindrical shells of an inner drum and an outer drum are pressed to form flat planes which have larger diameter than that of the penetrating pipe and to which the penetrating pipe is connected, the brims of the connection holes are perpendicularly bent outward for the outer drum and toward the combustion chamber side for the inner drum so that the penetration pipe comes in contact with the inside of the connection holes, and the penetrating pipe is fitted into them and welded. CONSTITUTION:To connect a penetrating pipe 11 to an outer drum 1, a part of the cylindrical shell of the outer drum 1 is pressed to form a raised flat plane 12 having a diameter larger than that of the penetrating pipe 11, and the brim of a hole is perpendicularly bent outward (burring) so that the penetrating pipe 11 comes in contact with the inside of the hole on the flat plane 12. After that, the penetrating pipe 11 is fitted into the hole and welded. On the other hand, to connect the penetrating pipe 11 to an inner drum 7, a part of cylindrical shell of the inner drum 7 is pressed in the same manner as for the outer drum to from a flat plane 12' having a diameter larger than that of the penetrating pipe 11 and the brim of a hole is perpendicularly bent (burring) toward the side of a combustion chamber 9. Then, the penetrating pipe 11 is fitted into the hole and welded. The clearance construction on a water chamber 8 side between the inner and outer drums 7 and 1 and the penetrating pipe 11 for fixing a heating element 10 can be made uniform and small throughout the circumference of the fitting part of the penetrating pipe 11 to the inner and outer drums 7 and 1.

摘要： PURPOSE:To achieve stable and high burning performance by arranging air smoothing holes at one end of a blow tube to be distributed in an area where the size of opening is larger and an area where the size of opening is smaller in correspondence with the static pressure distribution in a fan case. CONSTITUTION:When the start switch is turned ON, a fan 21 rotates to cause combustion air to flow to the burner head and, after being smoothed by air smoothing holes 30 in the bottom 30 of a blow tube 27, further to a combustion area 29. The dynamic pressure distribution in the B-B' section of the fan case 22 is such that it is higher at the upper left corner in the bottom of the tube 27 and is lower toward the lower left corner. Based on the Bernoulli's principle, the static pressure is low at the upper left corner of the bottom of the tube where the dynamic pressure is high, and the static pressure is high at the lower left corner of the bottom. On the other hand, the air flow rate flowing into the air smoothing holes 30 is higher where the static pressure is higher. Because the number of the air smoothing holes 30 is larger at the upper left corner of the bottom of the tube 27 and smaller at the lower left corner, the air flow rate flowing into the tube 27 becomes uniform, and the flame in the combustion area 29 becomes stable, thereby enabling high burning performance.

摘要： PURPOSE:To stabilize the burning by disposing an ignition electrode in a portion of the combustion air stream caused by a fan where the velocity component parallel with the plane made by the blow tube end is the smallest possible to a practical extent. CONSTITUTION:When the start switch is turned ON, a fan 21 rotates to cause combustion air to flow to the burner head 24 and to a combustion part 26 after being smoothed by multiple air flow smoothing holes 27 in a cylindrical blow tube 28. When the supply air rate reaches a certain level, a spark is generated at an ignition electrode 31, and fuel is jetted out of a fuel injection nozzle 30. The burning is then started in the combustion part 26 as the flame is held by a stabilizer 25. Because the dynamic pressure is relatively low in the part covering the lower right to the right of the end of the flow tube 28, and the speed of combustion air is relatively low in the plane parallel with the end of the blow tube 28, the ignition electrode 31 does not greatly disturb the combustion air flow along the plane parallel with the end of the blow tube despite the fact that the ignition electrode 31 projects from the end of the blow tube 28 into the fan case.

摘要： PURPOSE:To prevent dusts and dirts from depositing on a flame detector thereby to assure the stable operation of a boiler over a long period of time by mounting the flame detector on a fan case without recesses. CONSTITUTION:A transparent plate 23 having a high transparency is provided at the mounting part of a flame detector 22. The mounting part of the flame detector 22 is formed into a smooth plane having no recesses or protrusions. Thus, combustion air delivered from a blast fan 14 smoothly passes over the flame detector 22. Since dusts and dirts are difficult to deposit on the smooth surface, deposition of dusts and dirts on the flame detector 22 is prevented, and hence a stable action of the detector 22 over a long period of time is assured.

摘要： PURPOSE:To prevent the malfunction of a combustion detector by providing a bottomed cylinder having smoothing holes at its bottom within a blast case which supplies combustion air, forming a part of the bottom part of the inner cylinder by a transparent plate, and providing smoothing holes in the transparent plate. CONSTITUTION:A large number of smoothing holes 5 are formed at the bottom part of an inner cylinder 4 so that air to be introduced into the inner cylinder 4 is distributed uniformly. Combustion air is mixed with a fuel supplied through a nozzle 6 and is ignited by an igniter 7, and forms a flame circumferentially uniform and stabilized by a stabilizer 8. Further, combustion air flowing via a blast route 10 passes through air holes 9 and is supplied to the flame stabilized by the stabilizer 8 to promote the combustion and to cause the burner to carry out a complete combustion. A part of the bottom part of the inner cylinder 4 is made of a transparent plate 12; smoothing holes are formed in the transparent plate 12. Thus, uniformity of air passing through the bottom part of the inner cylinder 4 and entering therein is not impaired, and allows the light of the flame formed in the front of the stabilizer 8 to permeate through the transparent plate 12, thus making it possible to sufficiently supply the light thereof to a combustion detector 13. Hence, even when the quantity of light incoming to the combustion detector may be changed more or less, the detector does not malfunction.

摘要： PURPOSE:To lessen dust attachment to a sensor element by mounting a number- of-revolutions sensing element to sense the number of revolutions of a blower fan in the neighborhood of the fan case wind starting point within a fan case. CONSTITUTION:A number-of-revolutions sensing element 5 to sense the number of revolutions of a fan 12 is fixed to a fan case 13, wherein the sensing part protrudes into the fan case 13. The sensing element 5 is located in the position with smaller air passage in the neighborhood of the fan case wind starting point 22 between a throat 21 and a suction hole 19. Thereby dust attachment to the number-of-revolutions sensing element can be extremely lessened to lead to prevention of any failure in sensing of the number of revolutions.

摘要： PURPOSE:To enhance the suction efficiency by locating the air intake hole having a trumpet-shaped opening oriented toward opposite side of a plate-shaped damper to the fan side in the center of an edge-up part when damper having air intake hole blocks the whole edge-up part. CONSTITUTION:For varying the wind quantity a plate-shaped damper 7 is installed on a burner base 1 in such a way as movable round a fulcrum 9. An air intake hole 8 of the damper 7 is set so that the hole 8 is located in the center of the edge-up part 6 when the damper 7 blocks the whole edge-up part 6. Thus air suction by fan 5 will be made in the center of the fan 5, which makes uniform the pressure balance of the air to the fan 5.
