: : I would like to know the daily,weekly,monthly and annually maintenance needed to be done. : : Thank you. : Just as a point, this is in the National Board : main window this week. : SUGGESTED MAINTENANCE LOG PROGRAM : The following maintenance items, as appropriate to the specific boiler system, need to be considered for implementation on a regular basis (e.g., : daily, weekly, monthly, semiannually, annually). A checklist of the items should be incorporated into a maintenance log with provisions for : checking off the item for the appropriate period. A separate log sheet is suggested for each period. The log sheets can be filed in a loose-leaf : binder, and should be retained as a permanent maintenance record. : The log sheets can be used as a handy check-off system when establishing a facility maintenance program. In all cases the equipment : manufacturer's recommendations should be followed. : DAILY : Blow down and test low water cutoffs of steam boilers (once per shift for high pressure) : Blow down gage glasses (steam) : Blow down make up feeder (low pressure steam) : Blow down boiler (steam) : Check boiler control linkage : Check boiler and system for leaks : Check burner flame : WEEKLY : Check compressor(s) lubricating oil level (control and atomizing) : Check flame signal strength for both pilot and main flame, and record readings : Check flame failure cutoff and timing : Check pilot and main flame fuel shutoff valve closing : Check igniter and burner operation : Check level in chemical treatment tank : MONTHLY : Check compressor(s) air filter, and clean or replace as required : Check boiler water treatment test results received from treatment company, adjust treatment as required : Lubricate motor and equipment bearings : Test fan and air pressure interlocks : Check main burner fuel safety shutoff valves for leakage : Check low fire start interlock : Check high pressure / temperature interlocks : Test low water cutoffs (hot water) : For oil - test pressure and temperature interlocks : For gas - test high and low gas pressure interlocks : Manually lift safety/safety relief valves and check operation : SEMI ANNUALLY : Inspect burner components : Check flame failure system components : Check piping and wiring of all interlocks and shutoff valves : Recalibrate all indicating and recording gages and instruments : Perform a slow drain test for low water cutoffs (steam) : Check combustion control system : For oil - check atomizers and strainers : Test boiler safety/safety relief valves in accordance with ASME Boiler and Pressure Vessel Code, Sections VI and VII : ANNUALLY : Perform the SEMIANNUAL maintenance procedures : Check all equipment coils and diaphragms : Perform a pilot turndown test : Recondition or replace low water cutoff : For gas - check drip leg and gas strainer : Clean boiler firesides : Drain boiler, open manholes and hand holes, and clean watersides : Have boiler inspected by a commissioned inspector : Clean burner and fans : Replace gaskets : Leak-test all fuel valves : Test operation of al controls and safety devices : Have fuel-burning system adjusted using combustion test instruments : AFTER EACH PERIOD : Make a record of all maintenance and parts replacement in the maintenance log
