摘要： PROBLEM TO BE SOLVED: To provide a thick and thin type gas burner which, even when the gas nozzle has come out of position vertically somewhat in its position of attachment or deviated from the right position, enables the quantity of gas flowing into a gas-bifurcating mechanism to keep from variation and to be kept constant. SOLUTION: In a thick and thin type gas burner a thin gas with a large quantity of air, carried through a main passageway, is discharged from main burner ports at the upper end and bunt as main flames, whereas a thick gas with a smaller quantity of air, carried through an auxiliary passageway, is discharged from auxiliary burner parts adjoining the main burner ports at their outer side and burnt as a flame retention. In this constitution a funnel- shaped gas-induction guide 5 tapering in the direction of the flow of the gas is provided between a gas-bifurcating mechanism 3 and a gas-air inlet 1a.

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of heat exchange by passing water in a branched manner to a main heat exchanger and an auxiliary heat exchanger, and controlling the water flow quantity to branched pipes at least according to either the supply quantity of hot water or the combustion quantity of a burner. SOLUTION: Water to be fed is branched on the upstream side of a main heat exchanger 2 and an auxiliary heat exchanger 4, and passed into a water pipe 3 and a branched pipe 5. The water fed into the branched pipe 5 and the water fed into the water pipe 3 is respectively heated in the auxiliary heat exchanger 4 and in the main heat exchanger 2 respectively, and then, merged to each other, and supplied from a hot water supply pipe. A flow rate control valve 9 is provided on the upstream side of the auxiliary heat exchanger 4 in the branched pipe 5 to control the water flow quantity to the main heat exchanger 2 and the auxiliary heat exchanger 4. When the requested quantity of hot water to be supplied is small, and the combustion quantity of a burner is small, the flow rate control valve 9 makes a control so that the water flow quantity to the auxiliary heat exchanger 4 is increased. On the contrary, when the requested quantity of hot water is large, and the combustion quantity of the burner is large, the water flow quantity to the auxiliary heat exchanger 4 is decreased, and the water flow rate to the main heat exchanger 2 is increased.

摘要： PROBLEM TO BE SOLVED: To make it possible to maintain a predetermined burner port shape without dropping a metal plate even if the connector of a burner port surface side is damaged by providing a protrusion protruding at the upper or lower part of a contact part on the plates coupled by the connector disposed at the burner port surface side. SOLUTION: A protrusion 63 provided on a metal plate 1A protrudes from the upper part of a contact part 62 in the space 61 between metal plates 1A and 1C coupled with one another by a connector 53 protruding at a burner port surface side, and a protrusion 65 provided on a metal plate 1B protrudes from the upper part of the contact part 66 in space 64 between the plates 1B and 1D coupled similarly by a connector 54. Thus, even if the connectors 53, 54 are broken, the couplings between the plates 1A and 1C and between the plates 1B and 1D are interrupted, and the plates 1A, 1C are moved down, the protrusion 63 of the plate 1A is engaged with the protrusion of the plate 1C for forming the part 62 and the protrusion 65 of the plate 1B is engaged with the protrusion of the plate 1D for forming the part 66, thereby preventing the drops of the plates 1A, 1B.
