Claims (1)
ボイラ装置の燃料を制御するものにおいて、各バ
ーナ段に対する燃料の供給を行う回路に対して、
圧力偏差による燃料供給量修正信号を発する回路
と、再熱蒸気温度偏差による燃料供給量修正信号
を発する回路とを接続したボイラ燃料制御装置。 (2) 実用新案登録請求の範囲第(1)項記載におい
て、前記圧力偏差による燃料供給量修正信号を発
する回路は、燃料供給量の調節が下段バーナほど
多く影響するよう信号を発信し、再熱蒸気温度偏
差による燃料供給量修正信号を発する回路は、上
段のバーナほど多く影響するよう信号を発信する
よう構成したボイラ燃料制御装置。[Scope of Claim for Utility Model Registration] (1) In a boiler device that controls fuel in a boiler device in which burners are arranged in multiple stages in the height direction of the furnace, a circuit that supplies fuel to each burner stage,
A boiler fuel control device that connects a circuit that issues a fuel supply amount correction signal based on pressure deviation and a circuit that issues a fuel supply amount correction signal based on reheat steam temperature deviation. (2) In the utility model registration claim (1), the circuit that generates the fuel supply amount correction signal based on the pressure deviation transmits the signal so that the lower burner is affected more by the adjustment of the fuel supply amount, and The circuit that emits the fuel supply amount correction signal based on the thermal steam temperature deviation is a boiler fuel control device configured to emit a signal so that the higher the burner in the upper stage, the more the signal is affected.
