第１項に記載のボイラー用水位制御装置。 −ブロー率 −気水分離器補集効率 −缶内圧力 −蒸気乾き度。[Scope of Claim for Utility Model Registration] (1) The boiler 1 is provided with a water level detector 2 for detecting the water level in the can, and the water level in the can is maintained within a predetermined control range by the signal from this water level detector. In order to achieve this, in a water level control device that ON-OFF controls the water supply pump 3, a temperature detector 4 is provided to detect the water temperature at the inlet of the heating section 13 of the boiler 1, and the detected temperature is determined by a signal from this temperature detector. Comparison calculator 5 that functions to determine the optimum water level control range by lowering the water level control range when the water level is higher than the reference value, and increasing the water level control range when the water level control range is higher than the reference value.
A water level control device for a boiler, comprising: a controller 6 for controlling ON/OFF of a water supply pump 3 in order to maintain the controlled water level within the optimum water level control range. (2) Water level for a boiler according to claim 1, further comprising a reference value calculator 7 that calculates the reference value from a plurality of optional additional data extracted from the following data: Control device. −Blow rate −Steam separator collection efficiency −Inner pressure −Steam dryness.
