5.1. Condensate Storage Tank High Water Alarm

Purpose: High water level may be an indication of condensate transfer pump failure that could lead to low water condition in the feedwater deaerator and in the boilers. There may be a failure of make-up water controls.

Recommended set point: 4 inches below overflow level and 2/3 of tank height.

Potential hazards due to failure of high-water alarm: Feedwater deaerator running dry and, consequently, boiler feed pumps running dry will cause.

overheating and damage to pumps and potential for plant shut down. Failure of make-up water controls (in open position) could lead to significant cost from waste of water and condensate from the tank overflow if this occurs over a long time period.

Recommended type of device: Conductivity probe type switch. Float type switches have high failure rate in this application where they are exposed to flash steam that causes seals to harden and prevent float movement.

VA Master Specification section: 23 50 11 (old 15625).

www.va.gov/facmgt/standard/ VA Standard Detail: SD232111-05.pdf www.va.gov/facmgt/standard/ Failure rate of float types: 48% (BEI study of VA boiler plants).

Make and Model: Mercoid Float Did it function properly: No Category & Action Time Limit: Upon Failure or Within 5 Years Comments: Float type switches are not allowed for high water alarms. The VA recommended switch type is a conductivity probe type switch. Install the VA recommended switch and set to alarm at 2/3 of the tank height. There are valves that can isolate this alarm. These valves must be made lockable only in the operating position.

d) The draft report shall be submitted to the COR in Word format and include the following as attachments:

(1) On site technicians training documents and certifications.

(2) A list of all test instruments used during the certification and their current certification/calibration documents for each instrument.

(3) Hard copies of data sheets and flue gas analyzer “strip” printouts.

(4) One quote for each piece of equipment itemizing repairs referenced in III(A)(1)(b).

e) The draft report shall be reviewed by the COR and VHSO administration. Any required editing shall be completed by the contractor and submitted to the COR within 15 calendar days.

3. All safety-related deficiencies shall be immediately reported to the COR, Boiler Plant Supervisor and/or Chief Engineer during the inspection visit.

4. Boiler repairs identified and quoted by the contractor shall be performed by contract modification if approved by the COR and the Contracting Officer (CO). All repairs are to be started within thirty (30) days of contract modification. All repairs and a report documenting the repairs shall be completed within 30 days for COR review. Any edits required by the COR to all reports must be completed within thirty (30) days of COR notification.
