Claims (1)
量信号と燃料要求信号との偏差に基き燃料流量制御弁に
よって制御するようにした燃料流量制御装置において、
ボイラ負荷変化率に応じて自動的に異なるレベルの信号
を発信する信号発生器と、この信号発生器の信号を微分
する微分器と１、前記信号発生器と前記微分器との間に
各バーナ弁に対応して設けられそれぞれ対応するバーナ
弁の開閉に応じて開閉動作をする接点と、前記微分器の
出力信号を前記燃料流量制御弁への制御信号へ加える加
算器とを備えたことを特徴とする燃料流量制御装置。A fuel flow control device in which fuel supplied to a plurality of burner valves and the burner is controlled by a fuel flow control valve based on a deviation between a fuel flow signal and a fuel demand signal,
a signal generator that automatically transmits signals of different levels according to the boiler load change rate; a differentiator that differentiates the signal of this signal generator; and 1, each burner between the signal generator and the differentiator. A contact point is provided corresponding to the valve and opens and closes in response to the opening and closing of the corresponding burner valve, and an adder that adds the output signal of the differentiator to the control signal to the fuel flow control valve. Characteristic fuel flow control device.
