Boiler Maintenance and Repair (Scaling Calculation Reduction)Boilers that play a role in water conversion into steam requirespecialtreatment and care.Problems arising on the boiler are generally caused by boiler feed water thatdoes not meet the requirements. For the maintenance and maintenance of the boiler can be done in thefollowing ways:
1.Early Commisioning process
2.Operation under normal and emergency conditions
The Early Commisioning Process
The initial preparation process that is carried out both on a new boiler or an old boileris a main inspection consisting of the removal of scale or foreign material in the boiler after the hydrostatic test and inspection on the boiler leak. Kettle
operated byboiling method using alkali solution
to removeoil-bearingmaterialsand other deposits. During boiling, the boiler
operated atlow pressure maintained half of full pressure. Boiling time is approximately 24 hours
.For high pressure boilers
cleaning on chemistry
by reducing the substances made toremove the scale. After boiling or acid cleaning the boiler is
emptied, refilled and washed with fresh water. Boilers are then ready to operate atoptimal steam pressure anduse security buttons.
Operation in Normal and Emergency
Operation in normal circumstances be done by factories kettle that requires pemeliharaa nand condition air boiler that well for menceg ahemergence need or corrosion. Tocheck properly / well needed
note the steam and temperature of the steam produced andmaintain the cleanliness of the gas
. The time to start iand for cooling the boiler after it isturned off, it is specified in the manual of the boiler and must be followed / followed properly.Operation in an emergency is an important thing to note. This situationcan be in the form of errors in the supply of feed water or fuel preparations. Air loss orfault in combustion fire. Modern boiler units are equipped withautomaticsafety locksfor fuel supply flow and at the timethe kettle stops operating, ifa dangeroussituation occurs.
External cleaning is often done by curing and jetting gas or withrunningwater. Internal cleaning with water and steam is done manually if possible and can also use chemical cleaners automatically for modern kettle on unit boiler especially on part boiler that not all acould reachable by hands.Chemical cleaning should be done under the supervision supervision. Mosthydrochloricacidis used together with chemicals to remove hard crusts.Cleaningacid if made by uncompressed people can cause itexcess chemical substancesin the boiler.
After washing with acid, neutralize with alkaline solution and last time the boileroperated on pressure heating low with inert solution. When The kettle is stoppedfor a long period of about 1 or 2 months. Dry storage method is recommended to protect the boilerfrom attack corrosion. This would need ancleaning and drying that carefully against the boilerand cover all hole too eliminate itair and air in the room boiler and measuringinstrumentspressure.
