Abstract | To safely save manpower through automation of various types of adjustment, such as a flow rate of fuel gas, while improving economic efficiency by maintaining a simple configuration without providing a flow meter.SOLUTION: By operating a blower B, combustion gas A is caused to flow in on-site fuel piping H1 via on-site connection piping H3. While a fuel flow control valve RVg is maintained at a predetermined initial set opening and pressure at a primary side inlet is maintained at predetermined fuel flow rate control pressure by using the blower B, pressure at a secondary side outlet is set to be predetermined initial set secondary pressure by using a secondary side fuel pressure adjustment mechanism GV. Then, while fuel piping on-off valves SV1, SV2 are opened and a connection piping on-off valve SV3 is closed, the opening of the fuel flow control valve RVg is controlled on the basis of opening fuel flow rate relation stored in a storage section S3 to control a flow rate of fuel gas G to a target flow rate.SELECTED DRAWING: Figure 1
【課題】流量計を設けることのない簡易な構成を維持して経済性を向上しつつ、燃料ガスの流量等の各種調整の自動化による省人化を安全に実現できる。【解決手段】ブロアBを働かせて燃焼用気体Aを現場接続配管H3を介して現場燃料配管H1に通流させて、燃料流量制御弁RVgを所定の初期設定開度に維持し、ブロアBにて一次側入口の圧力を所定の燃料流量制御圧力に維持した状態で、二次側燃料圧力調整機構GVにて二次側出口の圧力を所定の初期設定二次圧に設定した後に、燃料配管開閉弁SV1、SV2を開放状態として接続配管開閉弁SV3を閉止状態としている状態で、記憶部S3に記憶された開度燃料流量関係に基づいて、燃料流量制御弁RVgの開度を制御して燃料ガスGの流量を目標流量に制御する。【選択図】図1 |
