1. a kind of diagnostic method of direct current cooker corrosion and scaling risk, it is characterised in that:

  • the following steps are included;

    When direct current cooker is operating status, diagnostic method are as follows;

    1) investigate direct current cooker water supply system whether cupric, except condenser;

    If cupric, direct current cooker do not use water supply systemWater purification mode should be all-volatile treatment mode;

    If water supply system cupric, the Water purification mode that direct current cooker uses is answeredFor reproducibility all-volatile treatment mode;

    This requirement is not met, then is determined as that boiler corrosion, fouling tendency are serious;

    2) above-mentioned water process mode meets the requirements, then enters and diagnose in next step;

    Whether complete investigate direct current cooker chemical instruments, ifChemical instruments are not complete, then are determined as that boiler corrosion, fouling tendency are serious;

    3) above-mentioned chemical instruments are complete, then enter and diagnose in next step;

    Whether investigation direct current cooker medicine machine and instrument have canBy property and availability, if medicine machine and instrument do not have reliabilty and availability, it is determined as that boiler corrosion, fouling tendency are tightWeight;

    4) above-mentioned direct current cooker medicine machine and instrument meet the requirements, then enter and diagnose in next step;

    Investigate whether monitoring data accord withThe regulation for closing 12145 exposure draft of GB/T that 2015 announce then is determined as no heavy corrosion knot such as monitoring data qualificationDirt tendency;

    If

         5) above-mentioned monitoring data are undesirable, enter and diagnose in next step;

    It investigates and whether locates in time by tertiary treatment principleReason is not handled according to tertiary treatment principle such as in time, then is determined as that corrosion and scaling tendency is serious;

    Since then, direct current cooker runs feelingsCorrosion and scaling diagnosis of risk under condition terminates;

    When direct current cooker is stoppage in transit state, diagnostic method are as follows;

    A) it first investigates whether using reasonable furnace stopping maintenance measure, i.e., when boiler down time is no more than seven days, using wet protectionMethod;

    Down time is more than seven days using dry Protection Code;

    If protection of boiler during shutdown period measure is undesirable, it is determined as that corrosion and scaling inclinesTo serious;

    Whether b) above-mentioned protection of boiler during shutdown period measure meets the requirements, then enters and diagnose in next step, carry out reasonably before investigating boiler operatiopnWater rinses, if not carrying out reasonable water rinses just operation boiler, is determined as that corrosion and scaling tendency is serious;

    C) above-mentioned water flushing meets the requirements, then boiler can operate normally, when hence into above-mentioned direct current cooker being operating statusDiagnosis process.
