LOW WATER LEVEL DETECTION CONTROL METHOD FOR BOILER

摘要

PROBLEM TO BE SOLVED: To safely and efficiently operate a boiler by preventing the generation of low water level trip due to an excessive fluctuation of water level of a water separator 14 generated by a load fluctuation. SOLUTION: Water level lowering time of the water separator 14 in the boiler is measured, and when the measured time is shorter than the lowering time of water level due to a lack of the water supply quantity, operation of interlock is delayed to prevent an unnecessary stop of the boiler.
