摘要:
A fluid distributor includes a first feed port for feeding fuel gas into a main fuel flow path, a feed path for feeding the fuel gas inside a gas flow path to the first feed port, and distributedly into a pilot fuel flow path so as to increase the distribution ratio of the fuel gas to the first feed port according to an increase in an overall feed flow rate of the fuel gas from the gas flow path to a feed path and, inversely, to decrease the distribution ratio of the fuel gas to the first feed port according to a decrease in the overall feed flow rate. A plurality of fluid distributors are disposed in the main fuel flow path and pilot fuel flow path distributedly in the peripheral direction to constitute a gas feed means.

Disclosed is a burner apparatus comprising an inner tube defining a second channel and an outer tube defining a first channel surrounding the inner tube, air supplying means for supplying air to the first channel and the second channel, and gas supplying means for supplying fuel gas to the first channel and the second channel, either the first channel or the second channel being used as a main combustion channel and the other being used as a pilot combustion channel, the main combustion channel and the pilot combustion channel receiving the supply of fuel gas for combusting it. A plurality of first supply openings for supplying the fuel gas into the main combustion channel are distributed in the main combustion channel in a direction away from the pilot combustion channel. Discharging resistance of the fuel gas from each first supply opening due to passage of the oxygen-containing gas is set so as to increase as being distant from the pilot combustion channel.

In the present invention, in a burner apparatus comprising an inner tube (2) defining a second channel (A2) and an outer tube (3) defining a first channel (A1) surrounding the inner tube (2), air supplying means for supplying air to the first channel (A1) and the second channel (A2), and gas supplying means for supplying fuel gas G to the first channel (A1) and the second channel (A2), either the first channel (A1) or the second channel (A2) being used as a main combustion channel and the other being used as a pilot combustion channel, the main combustion channel and the pilot combustion channel receiving the supply of fuel gas (G) for combusting it, said gas supplying means includes a plurality of fluid distributors (4) arranged in dispersion in a peripheral direction of the main combustion channel and the pilot combustion channel, each fluid distributor (4) including a first supply opening (5) for supplying the fuel gas G into the main combustion channel, a supply line (6) for supplying the fuel gas G present inside a gas channel (A3) to the first supply opening (5), and distributing means incorporated in the supply line for distributing the fuel gas (G) into the pilot combustion channel so that the distribution ratio of the fuel gas (G) to be supplied to the first supply opening (5) is increased in response to increase in a total supply amount of the fuel gas (G) from the gas channel (A3) and conversely the distribution ratio of the fuel gas (G) to be supplied to the first supply opening (5) is decreased in response to decrease in the total supply amount. And, the first channel (A1) is used as the main combustion channel and the second channel (A2) is used as the pilot combustion channel.

Disclosed is a burner apparatus comprising an inner tube defining a second channel and an outer tube defining a first channel surrounding the inner tube air supplying means for supplying air to the first channel and the second channel, and gas supplying means for supplying fuel gas to the first channel and the second channel, either the first channel or the second channel being used as a main combustion channel and the other being used as a pilot combustion channel, the main combustion channel and the pilot combustion channel receiving the supply of fuel gas for combusting it. The burner apparatus including a common channel formed at one end of the inner tube and the outer tube for supplying the oxygen-containing gas to the main combustion channel and the pilot combustion channel. A common supply opening discharges the fuel gas of the gas channel in the common channel from the upstream side in the flow direction of the oxygen-containing gas of the pilot combustion channel to the upstream side in the flow direction of the oxygen-containing gas of the main combustion channel. A common shielding member adjusts the inflow amount of the oxygen-containing gas for a common gas supply area which extends in a discharging direction of the fuel gas from the upstream side in the oxygen-containing gas flow direction of the common supply opening and from this common supply opening to the common channel.

The main combustion channel includes a mixing promoting member against which the fuel gas discharged from the first supply opening into the main combustion channel is collided to be diffused in the main combustion channel. Alternatively, the pilot combustion channel includes a mixing promoting member against which the fuel gas discharged from the second supply opening for supplying the fuel gas into the pilot combustion channel is collided to be diffused in the pilot combustion channel.

An oxygen sensor of a limiting current type includes a sensing element coated with a porous coating layer having a catalyst supported thereon. The catalyst includes at least one element selected from the group consisting of platinum, rhodium, palladium, iridium and ruthenium, and the content of the catalyst is not more than 50 wt % with respect to the total weight of the porous coating layer, and particles of the catalyst are dispersed within the porous coating layer at spacings of not more than 6 .mu.m. By using the catalyst, the influence of hydrocarbons to the oxygen concentration is reduced.
