Scalding/burns
Hot furnace / combustion tube / analyzer parts
– Parts of the analyzer can be very hot.
• Check the furnace temperature in the software.
• For maintenance the furnace temperature has to be less than 40°C.
High temperature / Burning of the skin
Hot combustion tube
• When the analyzer (HTF, resistance furnace) is switched on again after
switching off, the adjusted set point is driven immediately. Please
check this!
6.1 General information
6.1.1 Resistance furnace operation
Maintenance every 25 to 40 analyses:
• Replace the magnesium perchlorate of the moisture trap of the resistance furnace. To
save material, replace first the upper half. The next time replace the whole quantity. See
chapter “Filling the reagent tubes”. It is not necessary to replace the glass wool, unless it
is penetrated by dust and particles from the magnesium perchlorate.
Remark
The above is related to coal analyses.
6.1.2 Induction furnace operation
The maintenance example mentioned below is related to steel analyses and oxygen 99.5%
pure.
Maintenance every 100 analyses:
Or at least once a month
• Replace the magnesium perchlorate after the metal filter. See chapter Reagent tubes
filling
• Brush the metal filter. See chapter dust trap cleaning.
Maintenance every 500 analyses:
• Clean the metal filter in an ultrasonic cleaner. See chapter dust trap cleaning
Maintenance every 1000 analyses:
Or if 1/3 of the material turned grey
• Replace the paper filters.
• Replace the magnesium perchlorate of both glass tubes. See chapter Reagent tubes
filling
• Replace the sodium hydroxide. See chapter Reagent tubes filling
Maintenance every 2000 analyses:
• Replace the copper oxide in the catalyst furnace. See chapter Reagent tubes filling
• Replace the furnace cleaning brush. See chapter furnace cleaning brush-replacing
