本発明は、ガス燃料をバーナに供給するためのガス燃料
供給装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a gas fuel supply device for supplying gas fuel to a burner.
従来のガス燃料供給装置を第2図により説明する。 A conventional gas fuel supply device will be explained with reference to FIG.

いる。When igniting and starting the burner 1, the burner main valve 5 and vent valve 7 are each fully closed, the flow rate adjustment valve 3 is adjusted, and the gas fuel is lowered to a level lower than the source pressure applied to the flow rate adjustment valve 3. Control and supply the pressure for leak check. Thereafter, the flow rate adjustment valve 3 is fully closed, and the burner main valve 5 is checked for leakage. After confirming that there is no leak in the burner main valve 5, the burner main valve 5 is opened to supply gas fuel to the burner 1 and ignite it, and the flow rate adjustment valve 3 is opened to enter normal operation. If the leak check time is long and it takes a considerable amount of time to ignite, gas fuel will leak from the flow rate adjustment valve 3, and the pressure of the gas fuel on the upstream side of the burner source valve 5 will become higher than the burner source pressure. Something happens. In this case, when igniting the burner 1, the pent valve 7 is opened and the gaseous fuel is discharged from the atmosphere discharge pipe 6 to the atmosphere, and the pressure of the gaseous fuel in the fuel pipe 2 is lowered to the burner source pressure. Burner main valve 5 is open.
従来の装置では、リークチェックに長い時間かかり、燃
料管2内のガス燃料の圧力がバーナ元圧より高くなると
バーナ1の点火時にガス燃料を大気放出して圧力を調整
していたため、ガス燃料を無駄にしていた。With conventional devices, it takes a long time to check for leaks, and if the pressure of the gas fuel in the fuel pipe 2 becomes higher than the burner source pressure, the pressure is adjusted by releasing the gas fuel into the atmosphere when the burner 1 is ignited. I was wasting it.
本発明は、ガス燃料を無駄にすることを防ぐためのもの
であり、バーナ元弁をバイパスするバイパス管を燃料管
に設け、バイパス管にバイパス弁とオリフィスを配置し
たガス燃料供給装置を提供するものである。The present invention is intended to prevent waste of gas fuel, and provides a gas fuel supply device in which a fuel pipe is provided with a bypass pipe that bypasses a burner source valve, and a bypass valve and an orifice are arranged in the bypass pipe. It is something.

バイパス弁を閉じて通常の運転に入る。When the leak check becomes longer and the gas fuel pressure in the fuel pipe becomes higher than the burner source pressure, when igniting the burner, first open the bypass valve, let the gas fuel pass through the orifice, and the orifice increases the pressure to the burner source pressure. to send gas fuel to the burner. After that, open the flow rate adjustment valve, and when the gas fuel pressure drops to the burner source pressure, open the burner source valve,
Close the bypass valve and resume normal operation.

配置している。A fuel pipe 2 is connected to the burner 1, and the fuel pipe 2 is connected to a flow rate regulating valve 3, a shroud 4, and
and a burner main valve 5 are arranged. A bypass pipe 8 branches from the fuel pipe 2 on the upstream side of the burner main valve 5 and is connected to the fuel pipe 2 on the downstream side of the burner main valve 5. A bypass valve 9 and an orifice 10 are arranged in the bypass pipe 8 in this order from the upstream side.

ち、バイパス弁9を開く。When igniting and starting the burner 1, the burner main valve 5 and pent valve 7 are each fully closed, the flow rate adjustment valve 3 is adjusted, and the gas fuel is lowered to a level lower than the source pressure applied to the flow rate adjustment valve 3. Supplied after being rolled to the pressure for leak check. Thereafter, the flow rate adjustment valve 3 is fully closed, and the burner main valve 5 is checked for leakage. After confirming that there is no leak in the burner main valve 5, the burner main valve 5 is opened to supply gas fuel to the burner 1 and ignite it, and the flow rate adjustment valve 3 is opened to enter normal operation. If the leak check time is long and it takes a considerable amount of time to ignite, the gas fuel will leak from the flow rate adjustment valve 3, and the pressure of the gas fuel on the upstream side of the burner main valve 5 will be lower than the burner main pressure. It happens that it gets expensive. When this happens, when igniting the burner 1, the burner main valve 5 is kept fully closed and the bypass valve 9 is opened.

て通常運転に入る。Gaseous fuel enters the bypass pipe 8 from the fuel pipe 2, passes through the bypass valve 9 and enters the orifice 10. Orifice 10
When passing through, the gas fuel is lowered to the burner source pressure, enters the fuel pipe 2 from the bypass pipe 8, and is supplied to the burner 1. When the flow rate adjustment valve 3 is opened and the pressure of the gas fuel drops to the burner source pressure, the burner source valve 5 is opened and the bypass valve 9 is closed to enter normal operation.
以上のように操作することができるので、ガス燃料を大
気に放出することなくガス燃料圧力を所定圧力迄下げる
ことができるので、ガス燃料を無駄にするのが防止でき
る。Since the operation can be performed as described above, the gas fuel pressure can be lowered to a predetermined pressure without releasing the gas fuel into the atmosphere, so it is possible to prevent the gas fuel from being wasted.
