摘要： A combustion apparatus has a burner, a combustion box containing therein a heat exchanger, an exhaust passage in fluid communication with the combustion box, a fan for supplying the burner with combustion air, and a predetermined length of air suction duct in fluid communication with a suction opening formed in a fan casing. The air suction duct has: on a downstream end thereof, an outlet cylindrical portion which is smaller in diameter than a diameter of the suction opening in the fan casing and which lies opposite to the suction opening; and a flange portion which overhangs radially outward from a perimeter of the air suction duct adjacent to the outlet cylindrical portion into contact with that peripheral portion of the fan casing which forms the suction opening. The flange portion is provided with an auxiliary suction opening in fluid communication with a space surrounding the outlet cylindrical portion.

摘要： A gas turbine engine combustor defining a combustion zone therein and being adapted for receiving compressed air from a compressor. The combustor comprises inner and outer walls spaced-apart by a predetermined spacing distance and defines a cavity therebetween. The outer wall has a first area defining at least an impingement aperture therein, the impingement aperture permits fluid flow communication between the compressor and the cavity. The inner wall has a second area corresponding to the first area and defines a plurality of effusion apertures therein, the effusion apertures permitting fluid flow communication between the cavity and the combustion zone, and each of the effusion aperture defines a cross-sectional area smaller than that of the impingement aperture. The effusion apertures are disposed in groups having a predetermined geometric arrangement relative to the impingement aperture and define a ratio of number of effusion apertures to the impingement aperture of between about 2:1 and about 4:1. The combustor thereby provides damping of audible frequencies less that about 1600 Hz passing therethrough.

摘要： A gas burner is provided for use on the inlet end of a fire tube, and includes a mixer having attached to it a gas delivery pipe, fuel gas and air being combined in the mixer to provide mixed gas and air. A venturi is secured at its inlet end to the mixer to receive the flow of gas and air, the venturi serving to draw air into the mixer. A burner nozzle is affixed to the venturi outlet end and the burner nozzle and extends within the fire tube. A perforated tube surrounds the mixer/venturi and at least a portion of the burner nozzle. A sound absorbing flame cell housing surrounds the perforated tube. A flame arrestor closes an air inlet opening in the flame cell housing air and serves to permit air to pass into the flame cell housing but prohibits the passage of flame therethrough so that flame is confined within the interior of the flame cell housing. A sound absorbing flame arrestor cover is supported exteriorly of the flame cell housing and adjacent the flame arrestor and configured to permit free passage of air into the flame cell housing through the flame arrestor but prohibiting straight line passage of sound through the flame arrestor from the interior to the exterior of the flame cell housing.

摘要： An apparatus and method of operation designed to reduce undesirably high pressure oscillations in lean premix combustion systems burning hydrocarbon fuels are provided. Natural combustion and nozzle acoustics are employed to generate multiple fuel pockets which, when burned in the combustor, counteract the oscillations caused by variations in heat release in the combustor. A hybrid of active and passive control techniques, the apparatus and method eliminate combustion oscillations over a wide operating range, without the use of moving parts or electronics.

摘要： A gas-fired burner apparatus includes a porous combustion surface disposed in a combustion chamber substantially sealed to prevent entry of secondary air. A subatmospheric pressure is maintained in the combustion chamber by a natural or aspirated draft. The subatmospheric pressure cooperates with an aspirating flow of fuel to the burner apparatus to provide an increased flow of primary combustion air which reduces the combustion temperature and the emission of pollutants. Alternatively, the subatmospheric pressure may be used to achieve a given flow of primary combustion air with a reduced combustion surface area. Water heater and room heater applications of the burner apparatus are illustrated.

摘要： The invention is intended to suppress oscillatory combustion of a combustion apparatus. In the invention, acoustic closed ends are provided at an inlet side and an outlet side of the burner port unit, and the combustion apparatus is constituted so that the flame may be positioned between these closed ends, and a buffer chamber is provided at the inlet side. Thus, when the inlet side and outlet side of the burner port unit of the combustion apparatus are formed as acoustic closed ends, oscillatory combustion occurs easily. At this time, when the intake tube communicates at the upstream side of the inlet side closed end, and an exhaust tube communicates at the downstream side of the outlet side closed end, if the length of the intake tube and exhaust tube is changed, the air ratio and combustion amount for generating oscillatory combustion remain constant, and the oscillation frequency and oscillation pressure remain constant. In such condition, when a sound absorbing unit is provided in the buffer chamber, oscillation does not occur, and if the intake tube or exhaust tube is extended, oscillation does not occur.
摘要翻译：本发明旨在抑制燃烧装置的振荡燃烧。在本发明中，在燃烧器端口单元的入口侧和出口侧设置声学闭合端，并且燃烧装置构成为使得火焰可以位于这些封闭端之间，并且在入口处设置有缓冲室侧。因此，当燃烧装置的燃烧器端口单元的入口侧和出口侧形成为声闭合端时，容易发生振荡燃烧。此时，当进气管在入口侧封闭端的上游侧连通，排气管在出口侧封闭端的下游侧连通时，如果进气管和排气管的长度改变，空气比和产生振荡燃烧的燃烧量保持恒定，并且振荡频率和振荡压力保持恒定。在这种情况下，当在缓冲室中设置吸音单元时，不发生振动，如果进气管或排气管延伸，则不会发生振荡。

摘要： The present invention involves a combustion box of a gas furnace which experiences oscillating combustion. The combustion box employs an opening in the housing which is tautly covered with a diaphragm made of elastic material such as silicone rubber. The elastic diaphragm transmits noise and vibration generated by the oscillating combustion of the gas burners in the combustion chamber and thereby dissipates that vibration and noise.
