RESPONSES FOR REQUEST FOR INFORMATION

SOLICITATION # 1333ND18QNB190228060 – Repair Boiler SG-6

QUESTION: RESPONSE

1) What Welding Certifications/Repairs are required?

For these repairs on the non-pressure side of the boiler it is a AWS certified welder.

Repairs on the steam pressure side of the boiler would require R-1 Welding certification. The boiler currently hydro’s without any evidence of a leak so we do not anticipate the need for the higher welding certification.

2) Please note that the comment for 150 SF inspection may not be enough to make the full repairs. A note needs to be added that an Change Order will be issued if the work exceeds the estimated scope.

You are correct. Without removal of the skin to determine the location where the membrane failure has occurred this 150 SF is an estimated amount. If the repair falls into the amount no further action is required. If the repair exceeds the estimated amount the government will process a modification for the additional SF to make the full repair.

3) NIST to provide pictures of burner and burn through locations. Pictures from inside and outside the boiler are attached.

4) NIST (Dave Henry) to provide report from COEN as to repairs that were discussed (from SG-5).

An internal inspection of the COEN burner components to determine if the flame and hot gases during operations were properly direct to the center of the furnace and found that the burner air diffuse ring was badly disintegrated requiring replacement.

This component affects many aspects of the burner operation and flame placement in the boiler furnace. In its degraded state, it is a significant factor contributing to the cause of the boiler burn through and other operational issues.

5) NIST to provide POC for COEN burner for part required. NIST does not have this information.

6) Will a rental boiler be required while the repair is being done to the 80,000 pph English boiler?

No.

7) May we please have the approximate extent (in SF) of the refractory damage to the burner end wall and firebox?

150 SF

8) Can we do a hydrostatic test to 90% of the lowest safety relief set pressure (per National Board Code of Pressure Vessels) or is NIST requiring the removal of all safeties, blanking off safety ports and doing a 1.5 times hydrostatic test?

90% of Lowest safety relief set point pressure is sufficient.

9) Can you clarify what is required by NIST to “recertify boiler to full operation?”

Boiler needs to: 1. Hydrostatic testing of boiler, 2. Light off on both fuel sources, 3.

Run from low to high fire range while keeping visible emissions clear and spot testing at stack port NOx to insure current Permit to Operate Standards are met.

10) Does this require EPA testing of stack emissions? There is no stack emissions testing required for this repair.

11) On the replacement of the membrane is it required for the membrane material to have mill certs?

Yes – Submit a mill certification of material used to indicate that it meets the English Boiler specification of the membrane wall.
