Boiler combustion machine care and maintenance is common methodological collect, these do you understand?

1, pressure maintains

When stopping furnace time not to surpass a week, can use pressure to maintain. Make before process stopping furnace is stopped soda water fastens all fill full water namely, maintain beyond pressure for (0.05~0.1) MPa, maintain boiler water temperature to be in 100 ℃ above, can prevent air to enter boiler so inside. Safeguard the measure of the temperature of force of boiler internal pressure to be: Connect steam to heat by adjacent furnace, or this furnace heats regularly

2, wet maintain

Do not exceed a month when time of boiler out of service when, can use wet maintain. Wet maintaining is the soft water that makes the flood in system of boiler soda water contains lye, do not take steam space. Because have the aqueous solution of proper alkalinity to be able to form the oxidation film of a stability with metallic surface, prevent to corrode proceed thereby. In wet maintain in the process, answer to use drying-out of low baking temperature regularly, maintain heating surface exterior and dry. Open pump to make boiler circulation flows regularly. The alkalinity of water of regular chemical examination, if alkalinity is reduced,should fill appropriately add lye.

3, dry method maintains

When time of boiler out of service is longer, can use dry method to maintain. Dry method maintains point to the means that desiccative sets to undertake defending inside the chamber of a stove or furnace is reached inside boiler. Particular way is: After stopping furnace, put boiler water clean, use the chamber of a stove or furnace drying of boiler of Yu Wen general, broken bits dirties in time inside cleared boiler, will put of the tray of desiccative next furnace platoon is reached to go up inside drum, door of all valve and manhole, hand-hole is closed after. Regular examination maintains circumstance, change in time the desiccative of invalidation.

4, aerate maintain

Aerate maintain can use at stopping furnace for a long time to maintain. After boiler stops furnace, do not want to turn on the water, make water level maintains go up in line of high water level, adopt measure to make boiler to oxigenate, isolate boiler water and outside next. Know nitrogen or ammoniac energy of life, the pressure after making aerate is maintained in (0.2~0.3) MPa. Because nitrogen can generate oxidation nitrogen with oxygen, make oxygen cannot be contacted with armor plate. Ammoniac dissolve makes after water water is shown alkalescent, prevent oxygen effectively to corrode, because this nitrogen and ammonia are very good antiseptic. Aerate maintain the effect is better, the close sex that protects it to ask system of boiler soda water has been had.
