Executive Summary

The Newington VA Medical Center is an ambulatory care center that provides primary and specialty care to veterans. The campus has a main complex and a set of auxiliary buildings, which are powered by a central plant with three water tube boilers and a chiller plant. The boilers are outdated, inefficient, and no longer comply with current VA standards, and need to be replaced with new equipment that can meet the current and future demand for heating. The boilers also need to have seamless fuel firing transition capability, which they currently lack. This project will address the installation and operation of a temporary boiler unit at the Newington facility to ensure uninterrupted service during the heating season. The project aims to enhance the quality of healthcare delivery and the healthful environment for the veterans and the staff.

Existing Conditions

Existing Boiler Plant

The existing steam-generating boiler plant consists of three dual-fuel steam boilers that are beyond their expected life. Two of the boilers (Numbers 2 and 3) are 20,580 lbs/hr and were installed in 1958.

Currently, Boiler number 3 is off-line due to a concern with a weak piping flange. Boiler number 1 is

12,000 lbs/hr and installed in 1975. The fuel oil tanks were removed in 2023 and natural gas is the lone fuel source for the boilers currently.

These boilers are headered together to provide 90 pounds of steam in the winter months and reduced pressure of 30 pounds of steam in the summer months to the respective distribution loops for the campus serving the hospital sterilizers and heating coils. Prior studies have indicated that a hot-water generating boiler plant could be installed to better serve the needs of the campus, but the alterations to the campus distribution system to incorporate those changes is outside of the scope of this project.

Known deficiencies with the Boiler Plant: (per VHA Directive 1810-2023):

1. Two-valve isolation not installed on steam supply system (Appendix B, section 3.f)

2. Redundant fuel option is lacking (Appendix B, section 2.a.3)

3. Boiler line-of-sight requirements are not in compliance with VHA directive.

4. Gas line location is not in compliance with PSRDM.

5. Plant set-backs are not in compliance with PSRDM.

Design Considerations – Temporary Boiler

Two respective design projects are being considered for this project. The first and chronologically more important one is providing a design for a reliable back-up boiler or temporary boiler plant to provide reliable redundancy in case the existing aged boilers cannot meet the heating demand.

One option has been selected by the VA for providing redundant steam to the campus distribution system.

1. Installation of one 500HP temporary boiler on trailer outside of the boiler plant, while the existing

Boiler 3 is being repaired.

This least-intrusive and most-simple option does not require major demolition work inside the boiler plant.

The temporary boilers are also rental units and will be returned to and removed by the vendor at the end of the contract.

Boiler #3 is beyond its functional life and is prone to break down or even fail. The recommended repairs will address currently-known issues, however, any other potential failures due to age are unknown and difficult to plan for. A third-party assessment for repairs to Boiler #3 is planned for by the VA, but not provided at this date.

Temporary Boiler Option – Temporary Boiler mounted outdoors in a trailer during the Repair of

Current Boiler #3

Advantages

Retaining the existing Boiler #3 provides the VA with functional (temporarily, at least) boiler option that does not require additional equipment purchases. This will also be the most cost-effective option if there are no unforeseen repairs or breakdowns beyond what VA staff at the boiler plant have disclosed from a past inspection report and repair quote. While the existing boiler is being repaired, a temporary boiler mounted outdoors in a trailer will assume its place to ensure uninterrupted N+1 duties.

The temporary boiler is a rental unit in a large trailer, the rental period is only for the duration of the repair of existing Boiler #3 with a minimum of 6 months, and the trailer is returned to and removed by the vendor at the end of the rental period. This rented trailer houses one 500 HP boiler.

The vendor states that it is acceptable for the VA to assume the operation and maintenance of the rental equipment for the duration of the rental period.

In case of a breakdown of the rental unit, the vendor states that service personnel can be dispatched immediately and be on-site within 6 hours of notification.

Disadvantages

Boiler #3 is beyond its functional life and is prone to breakdown or even failure. The recommended repairs will address currently-known issues, however, any other potential failures due to age are unknown and difficult to plan for.

The rental fees are charged continuously and may become very expensive if the temporary period is prolonged.

In case of a complete failure of the rental unit, the vendor states that replacement units would depend on equipment availability at the time. If a complete trailer replacement is needed and available, relocating the replacement equipment is normally a permitted transport load which would require a few days.

Operation and maintenance of rental equipment duties may vary with different vendors other than the quoted Delval Rental Systems.

Electrical Basis of Design

To provide power to the temporary boiler system, power will be tapped from the exiting boiler plant electrical equipment. This will be connected downstream of ATS-6 to ensure continued operation of the temporary boiler during loss of utility power. The tap will occur at the secondary side spare lugs of fused disconnect switch (BPMCC-FDS). Power will be fed to a new fused disconnect switch (FDS-1) installed as close as allowable to BPMCC-FDS. Post FDS-1, power will be stepped up from 208V to 480V in a delta-delta transformer located in a room adjacent to the boiler plant electrical equipment room. The transformer will be temporary and rented along with the temporary boiler. Immediately following the temporary transformer will be another new fused disconnect switch (FDS-2). From FDS-2, feeders will be routed through surface mounted or hung rigid metal conduit (RMC) to a penetration point in the existing boiler plant’s south wall and then along the rooftop in line with temporary boiler piping. Prior to temporary boiler connection point, conduit will be switched to flexible metal conduit (FMC) to avoid hardware displacement caused by temporary boiler starting and operating vibration. Pump P-1 shall be powered from a temporary panel provided with and located in the temporary boiler trailer. The temporary transformer will be removed and returned in parallel with the temporary boiler. The remaining fused disconnect switches, conduit, cable, and ancillary hardware will remain on site to be handled at

Newington VAMC’s discretion. Heat trace for the temporary boiler steam piping will be circuited into existing panel 6110-0476 in Building 3, room 11-101. Conduit for this circuit shall be routed adjacent to temporary boiler power circuit conduit up to a junction box adjacent to the south wall penetration. The heat trace will be splice to the feeder at this junction box.
