Boiler Inspections summary of requirements: Annual internal and external inspections are required for each boiler. Internal inspections of the feed water de-aerator pressure vessel are required every six years or more frequently if welding repairs have been performed. Contractor shall coordinate with COR to schedule an inspection. The Contractor shall ensure coordination and scheduling of any inspection is conducted at least two weeks prior to the intended date of an inspection. Inspections must be scheduled for periods when the VA determines that the boilers that will be inspected internally will not be needed for steam supply and when the COR or his/her designate is available on site to monitor the inspections. To maintain steam service, typically only one boiler at a time will be scheduled for internal inspections per inspection visit. Thus, multiple visits will be necessary every year to inspect all the boilers internally. The annual Internal/External Boiler inspections are to be performed in June, July and August. Feed water de-aerator pressure vessel inspections must be scheduled during periods of low steam demand. Coordinate the inspection schedule with the COR so that VAMC can have personnel available to monitor the inspections. Boilers scheduled for internal inspection will be prepared by the contractor prior to the scheduled arrival of the Qualified Professional Inspector. This includes cooling the boilers to near ambient temperature and having all man ways, hand holes and furnace access doors open; the boilers cleaned of loose materials waterside and fireside; electrical lock-out, tag-out in place; connecting piping isolated; proper illumination provided; compliance with confined space access requirements including having safety personnel present in the boiler plant. Similar advance preparations will be made to the feed water de-aerator when it is scheduled for internal inspection. VAMC will comply with any other requirements of the contractor that are considered reasonable by VAMC and have been presented in writing at least two weeks prior to the scheduled inspection. The boiler and feed water de-aerator inspections shall comply with the guidelines in the current issue of the NATIONAL BOARD INSPECTION CODE, Part RB, In-service Inspection of Pressure-Retaining Items, and ASME Boiler and Pressure Vessel Code, Section VI or VII as applicable. In addition to those guidelines, the inspections shall comply with all requirements listed in statement of work. The inspector must completely enter the internal spaces of the boiler or feed water de-aerator and visually inspect all internal surfaces that can be accessed. Methods for testing safety devices shall comply with VHA Boiler Plant Safety Device Testing Manual, 5th Edition. Summary of the minimum inspection requirements for boilers: Review the boiler history including: operating conditions, date of last inspection, current inspection certificate, ASME stamping on boiler, National Board registration number, history of repairs and modifications. Review boiler logs, water test reports, and reports on tests performed on the burner controls and interlocks. Assess the external parts of the boilers and boiler accessories and piping and valves for safety, accessibility, proper maintenance and operation, cleanliness, and compliance with codes. Inspect for evidence of leakage of combustion gases or fluids, externally and internally, including all gaskets. Inspect foundations for signs of stress such as cracking or movement. Inspect boilers externally and internally for defects including bulges, blisters, cracks, wasted or eroded material, warping, general corrosion, grooving and pitting, damaged insulation. Inspect all accessible internal surfaces for waterside and fireside deposits, including scaling, sediment, debris, carbon deposits. Examine all stays and stayed plates. Inspect gas side baffles. Inspect internal drum surfaces and steam separating internals. Inspect tubes, tube ends and tube alignment. Check for sagging tubes. Set combustions for boilers number one, two, and three, on natural gas and number two oil. Test all safety devices and perform annually required accumulation tests on boilers one, two and three. Verify that all nozzles of internal piping such as feed water admission and bottom blow off collection are clear with no obstructions. Inspect seating surfaces of man ways and hand holes. Check that boiler structure is plumb and level with no excessive deformations. Check for missing items such as bolts and nuts. Examine all valve and pipe connections to the pressure vessel. Inspect refractory including burner throat, expansion joint, bull ring, furnace seals, furnace walls and floor. Verify proper alignment of burner assembly. Inspect furnace for evidence of flame impingement. Test operation of water level gage glass. Perform mechanical and electrical inspection of disassembled low water cutouts. After reinstallation, test operation to the extent possible. Test low water cutouts on hot boilers by lowering water level gradually. Verify that steam pressure gage is properly calibrated. Test operation of high steam pressure cutouts on hot boilers by raising steam pressure. Inspect safety valve installations and verify that the valves have proper capacity and set pressure and valves, drains and vents are properly installed. Verify that valve locking seals are not broken. On boilers that are hot, perform an operation test under pressure to confirm operation at proper set pressures. Operate boiler with burner at high fire to verify adequate steam flow capacity of the safety valves ( accumulation test ). Inspect piping connected to the boilers for evidence of leakage, provision for expansion, provision of adequate support, proper alignment, and evidence of detrimental conditions. Inspect piping to the water column, low water cutoffs and alarms, gage glass. Verify that interior of piping is clear of obstructions. Inspect valves on boiler feed water, blow down, drain and steam systems. Perform service and Calibration of boiler instrumentation and controls. Provide recommendations for non-destructive testing when the inspections indicate that this is necessary to assure continued safety and reliability under current operating conditions. Summary of the minimum inspection requirements for Feed water Deaerators: Review the feed water de-aerator history including: operating conditions, date of last inspection, current inspection certificate, ASME stamping, National Board registration number, materials of construction, extent of post weld heat treatment, history of repairs and modifications. Assess the external parts of the feed water de-aerator and accessories and piping for safety, accessibility, cleanliness, proper operation, and compliance with codes. Test hazardous gas monitoring system. Inspect for evidence of leakage. Note feed water de-aerator pressure gage and thermometer readings and verify gage and thermometer accuracy. Inspect safety valve installation and verify that the valves have proper set pressure and capacity and are properly installed. Perform an operation test under pressure to confirm operation at proper set pressures. Verify that the de-aerator can safety withstand the test pressure prior to testing the valve(s) in-situ. Verify that non-condensable gas vent line is open and proper orifice is provided to permit venting of gases. Inspect support structures for proper integrity and allowance for thermal expansion. Internal Inspections Visually inspect all visible pressure vessel surfaces for corrosion, material thinning, deposits, and weld cracking. Inspect spray nozzles and trays.
