摘要： PURPOSE:To prevent the base plate and backer plate of the valve mechanism part of air flap valve from the dew condensation of vapor by equipping the temperature regulation mechanism together with providing a heating body to heat the base plate and backer plate respectively. CONSTITUTION:Where the temperatures of the base plate 19 and backer plate to be detected by the temperatue detector 27, 28 are lower than the specified dew condensation preventive temperature, an electric current is sent to the heater before the pulse combustion begins, and the plate 19 and plate 20 is heated respectively. When the temperatures of 19 and 20 reach not lower than the specified dew condenstion preventive temperature, the sending of electric current to 25 and 26 is stopped. At the same time, the air for combustion and the gas for fuel are supplied in the combustion room and the pulse combustion begins. From the reasons stated above, it is not feared that the vapor, included in the combustion gas during the pulse combustion, produce the dew condensation at the base plate, the backer plate and the like of the valve mechanism part 5.

摘要： PROBLEM TO BE SOLVED: To provide a combustion apparatus which is compact with a higher efficiency and achieve a larger capacity varying range of an output. SOLUTION: It is so arranged to include a passage 11, a secondary air supply pipe 12 to supply secondary air to the passage 11, a vaporization chamber 13 arranged in the passage to have an open face on the downstream side of the passage 11, a flame hole part 15 which is arranged to cover the open face of the vaporization chamber 13 and has a plurality of flame holes 14, a primary air supply pipe 16 which is connected to the vaporization chamber 13 to supply primary air to the vaporization chamber 13, a fuel supply pipe 17 which is connected to the vaporization chamber 13 to supply a liquid fuel to the vaporization chamber 13 and a heater 18 which heats the vaporization chamber 13 to vaporize a liquid fuel supplied into the vaporization chamber 13. The vaporization chamber 13 and the flame hole part 15 have each a flat shape in the cross section of a path through which a fuel and the primary air reach the frame holes. Heat released from the external walls of the vaporization chamber 13 and the flame hole part 15 is recovered by the secondary air to improve the efficiency of a combustion apparatus as a whole with a reduction in heat loss. This also increases the area of the internal surface of the vaporization chamber 13 with respect to the capacity of the vaporization chamber 13 thereby achieving an efficient vaporization of the fuel.

摘要： PURPOSE:To conduct a comfortable heating by alternately heating indoor units at least with its set heating capacity based on a heating state of the units when the heating with the indoor units is conducted with the set capacity or less in an apparatus for air conditioning one room with a plurality of the indoor units. CONSTITUTION:When a controller 29 detects a heating operation of both indoor units 1, 3 with set heating capacity or less based on an operating Hz decided by operating Hz deciding units 13, 21 in circumstances in which both the units 1, 3 are operated to heat, it stops either one unit. The controller 29 corrects the operating Hz by the unit 1 to a value added with the operating Hz by the stopped unit 3, and heats a room only by the unit 1. The controller 29 continues the heating only by the unit 1 for a predetermined time, then heats only by the unit 3 this time, and then alternately operates only the one unit while the units 1, 3 must operate to heat with the set capacity or less.

摘要： PURPOSE:To discharge the vaporized fuel at a steady flow during a low fuel flow rate in the same way as it is at a high fuel flow rate by providing a fuel reservoir to store part of the liquid fuel that is supplied to the main body of a carburetor and inserting the end section of a wick on the side of the suction into the inside of the fuel reservoir. CONSTITUTION:With a carburetor 4 the fuel is sucked up from a fuel pump 11a to a wick 12 through the fuel in a fuel reservoir 13 that is filled while in the high combustion zone in which the quantity of combustion is much, and the pulsating flow is absorbed by the fuel stored in the fuel reservoir 13. Namely, when in the pulsating flow that enters a casing 5 from the fuel reservoir 11a, the fuel does not enter the casing 5, the fuel that is stored in the fuel reservoir 13 is sucked up alternately to the wick 12 through the end section 14 for suction. With this arrangement the fuel suction by the wick 12 is continuous without an intermission even if the fuel entering the carburetor 4 pulsates. However, the vaporized fuel out of the fuel injection nozzle 3 of the carburetor 4 is a flow with no variation, that is, a steady flow.

摘要： PURPOSE:To reduce nitrogen oxide concentration without particularly changing carbon monoxide concentration in exhaust gas, by a method wherein cross- sections of a combustion chamber and a tail pipe, coupled to the combustion chamber, are formed in the shape of an oval or a rectangle, both having length in a longitudinal different from that in a lateral direction. CONSTITUTION:The cross-sections of a combustion chamber 14 and a pair of branch pipe parts 16, with which a tail pipe 15 is formed, are formed in the shape of, for example, an oval having length in a longitudinal direction different from that in a lateral direction, and the combustion chamber 14 and the branch pipe parts 16 are installed in a manner that their longitudinal directions are extended in a vertical direction. This constitution enables increase of a heat transfer area of each of the combustion chamber 14 and the tail pipe 15 compared with that available when they are formed in the shape of a circle in cross section. Thereby, nitrogen oxide concentration can be reduced without particularly changing carbon monoxide concentration. A relation between a length L1 of the combustion chamber 14 and a length L2 of each of a pair of the branch pipe parts 16, with which the tail pipe 15 is formed, is set to L1/L2

摘要： PURPOSE:To suppress the amount of NOX exhausted and to reduce a running cost, by employing a structure for heating an outer pipe and installing a muffler between a tail pipe and the outer pipe. CONSTITUTION:An outer pipe 25 with a bottom is concentrically installed around a tail pipe 3 of a head part 1. The opening part side of the outer pipe 25 is communicated with the open end of a passage 8 of the head part 1, and an exhaust passage 26, through which the opening part of the tail pipe 3 is connected to an exhaust port 9, is formed by a space provided between the tail pipe 3 and the outer pipe 25. This enables formation of a heating part 27 which can heat the outer pipe 25 by means of combustion gas exhausted through a tail pipe 6. A pipe 29, forming a cylindrical muffler with a bottom having a number of pores 28a bored in the peripheral surface and the end surface, is placed so that it surrounds the tail pipe 3. This enables reduction of the amount of NOX exhausted and a running cost, and allows reduction in the total size of a device.
