Estimating the term…
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.
A burner apparatus comprising an inner tube defining a second channel and an outer tube defining a first channel surrounding the inner tube, oxygen-containing gas supplying means for supplying oxygen-containing gas 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 fluid distributor disposed across three channels including first and second channels through which a first fluid is caused to flow and a fluid channel through which a second fluid is caused to flow, so that the distributor distributes the fuel gas inside the fluid channel between the first channel and the second channel;
