摘要： PURPOSE:To effectively deaden the noise of combustion without increasing the resistance to the flow of exhaust gas by providing silencing chambers which are defined by perforated plates forming walls of a bent duct for exhaust gas and are stuffed with sound-absorbing material. CONSTITUTION:In a hot-water supplier, a fan supplies air to a combustion chamber where gas is burned to heat water in a heat exchanger and an exhaust duct 27 conveys the exhaust gas to an outlet 13 to discharge it out of the system. At the exhaust duct 27, the sound of the exhaust gas, which includes the noise from the rotation of the fan and the sound of the combustion, is reflected by perforated plates 22, 23 and by the surfaces 21a, 21b, 21c, 21d of a partition 21 and becomes attenuated by interference with the reflected sound. On the other hand, sound components in a relatively high frequency zone pass through the perforations 24b, 24c in the perforated plates 22, 23 and the perforations 24a in the surfaces 21a, 21c, 21d of the partition 21 and become absorbed by sound-absorbing material 25 in silencing chambers 26a, 26b, 26c. Furthermore, the flow of exhaust gas undergoes constriction at a narrowing 27a in the passage and then expands at an expanding part 27b so that the sound pressure of the exhaust sound is also reduced. As a result, the noise emitted from the equipment through the exhaust outlet 13 can be reduced considerably.

摘要： PURPOSE:To obtain good mixing ratio of gas with air, by directly feeding air to a mixed-gas feeding header and to a plenum chamber without giving pressure losses, in a type of gas burner in which the air needed for combustion is forcibly fed by a fan. CONSTITUTION:The outlet of a fan 1 is directly opened to a plenum chamber 3 being partitioned off in a combustion case 11. A mixed-gas feeding header 5 which has a plurality of juxtaposed burners 4 is provided in the plenum chamber 3. Gas injection nozzles 6 of the same number as of burners 4 are provided to a gas manifold 12, corresponding to each burner 4 respectively, being interposed by apertures 7 provided on the mixed-gas feeding header 5. Besides a mixed-gas contrarotator 8 is provided in the mixed-gas feeding header 5. A structure is such that the air supplied by the fan 1 is fed into the plenum chamber 3, and the mixed-gas feeding header 5 sucks the air fed into the plenum chamber 3 through a number of apertures 7 as primary air. Accordingly the air can be fed smoothly without receiving resistance.

摘要： PURPOSE:To reduce a partial difference in temperature at an intermediate part of a combustion cylinder and reduce a thermal condition of surplus heat to a hot water feeding pipe by a method wherein a water supplying pipe and a hot water feeding pipe which are continuously formed to a water pipe are arranged along an outer circumferential surface of a vertical intermediate part of the combustion cylinder. CONSTITUTION:Water pipes 2b... are formed as one pipe with each of their ends being connected to each other and at the same time its both ends are extended, thereby a water feeding pipe 2b1 is continuously formed to one end and a hot water feeding pipe 2b2 is also continuously formed to the other end. The water feeding pipe 2b1 and hot water feeding pipe 2b2 are wound along an outer circumferential surface of the inner barrel 1a of a combustion cylinder 1 positioned between a heat exchanger 2 and a burner 3 while they are adjacent to each other. An extremity end of the water feeding pipe 2b1 is connected to a water supplying coupler pipe 4 and an extremity end of the hot water feeding pipe 2b2 is connected to a hot water feeding coupler pipe 5, respectively. Heat at the intermediate part of the combustion cylinder is transferred to the water feeding pipe 2b1 and the hot water feeding pipe 2b2, thereby its temperature is decreased to reduce a thermal stress at the position, heat at the hot water feeding pipe is transferred to the water feeding pipe and then a so-called after- boiling within the hot water feeding pipe is prevented and at the same time temperature in the water feeding pipe is increased.

摘要： PURPOSE:To uniformly disperse a surplus wall thickness generated by driving swollen parts over the entire surface of a burner port thereby to prevent the burner from buckling by slightly bending the burner port surface to the inward of the burner in the latitudinal direction thereof and thereafter rectangularly bending both side surfaces with respect to the burner port surface. CONSTITUTION:A metal die B is brought into contact with the inner side of a burner port surface 1 to bend both side surfaces 2 and 2 thereof into a substantial U-shape, and the metal die B is drawn out at a position where the inside protrusion ends abut against the side surface of the metal die B. Further, both side surfaces 2 and 2 are bent until they become flat, and outer peripheral parts are brought into contact with each other and joined. The ends of respective side surface 2 and 2 continuous to long side edges 1b and 1b of the burner port surface 1 are swollen outward of the burners. Swollen part 2' and 2' are driven into the inside of the burner so as to be formed into a planar shape. Surplus wall thickness generated by driving of the swollen parts 2' and 2', fully circulate in the bending direction of the burner port surface 1, whereby the wall thickness is uniformly dispersed over the entire burner port surface 1.
