Abstract


Drum water-level is important parameter of the boiler.It influences the operating reliability and economics of the boiler.This paper elaborates and analyzes the aspect existent problem of the water-level diagraph to give analysis to the power station after the document delivered by national power corporation《Some Prescript About Configure、Installation And Employ Drum Water-Level Instruments System In Power Stations By national power corporation》,studying the measurement characteristic to various instruments.Propose that the difference-pressure type water-level instrument is more precise project measuring technique,how the connection formula pluviograph does reduce the measuring error the suggestion.And unified the new power plant actual situation to design the differential pressure pluviograph in the water monitor protection system application set of plans,and proposed how the protection system did solve the false water level to create the protection disoperation the good method.
