RECOVERY ACT BOILER PLANT DEFICIENCIESSTATEMENT OF WORK Correction of Safety and Reliability Deficiencies Boilers and Boiler Plant Auxiliary Equipment VAMC Clarksburg, WV May 2009 General Requirements: Work on burners and control systems must be performed by a skilled boiler/burner controls service technician. Upon completion of each item, test operation and provide data sheet showing test results including set point and operating point. All testing procedures must comply with VHA Boiler Plant Safety Device Testing Manual, 3rd Edition. Boilers: 1. For Boilers #1 & 2: The high pressure gas fuel cutoff switches (HPFCS) are not located properly. They are now located downstream of the fuel flow control valve where the gas pressure varies when the burner firing rate varies. The proper location is between the gas pressure regulator and the flow control valve, where the pressure is constant. This will protect against a regulator failure at all firing rates. a.Relocate the switches as shown on attached Burner Gas Piping Schematic Diagram. Connections between switches and gas piping must have lockable valves and valved test ports. b.Adjust set points to 120% of regulated gas pressure. c.If there are nuisance burner trips due to inaccurate gas pressure regulation, the pressure regulators must be repaired or replaced to provide the required accurate pressure control. This will make the burner operation more efficient at low loads and allow proper setting of the pressure switch for maximum safety. d.Test switch and interlock operation. 2. For Boilers #1 & 2: The proof of closure switches (POC) on the automatic oil fuel safety shut off valves open at about 60% of valve stroke. The POC switches are "valve seal overtravel" switches and it is apparent that the valves are not properly adjusted when the POC are still made at 60% of valve stroke. It is likely that the valves are flowing oil when the POC switches are made. a.Repair or replace valves. Valve repair must conform to the requirements of the valve manufacturer. b.Test valves for seat leakage and for proper operation of the POC switches. 3. For Boilers #1 & 2: The pre-purge airflow proving switches are not plumbed correctly. a.Replumb the pressure sensing lines to measure pressure differential between the forced draft fan discharges (after any dampers) and the boiler outlets, before the economizers. b.Adjust the switches to "make" at 80% of the maximum pressure differential at high fire. c.Test the switch and interlock operation. 4. For Boilers #1, 2 & 3: The existing forced draft fan motor interlocks not sufficient to prove the forced draft fans are actually running. a.Install "Symcom Model 777" or "Veris Industries Hawkeye 300" forced draft fan motor interlocks that monitor current flow on each power leg and loss of a phase. Connect to burner management control interlock circuits. These devices have provisions for testing the interlock. b.Test interlock operation 5. For Boilers #1 & 2: On each boiler provide low flue gas oxygen interlocks in the burner management control circuits that will automatically shut down the burners if the flue gas oxygen falls below a safe level. a. For Boilers #1 & 2:Utilize the existing flue gas oxygen analyzers to provide the low oxygen signals. b. For Boilers #1, 2 & 3: The existing flue gas oxygen analyzers are reported to be not functioning properly. They must be placed in satisfactory operation by a trained technician. c. For Boilers #1 & 2:Adjust the set points of the interlocks to approximately 0.5% oxygen above the point where the flue gas CO starts to climb above 200 ppm. 6. For Boilers #1, 2 & 3: Provide alarm and burner interlock for control air pressure failure. Control air operates the boiler feedwater flow control valves. As an option, the feedwater control valves could be converted to electric operation. a.Locate pressure switches downstream of the air pressure regulators serving the boiler feedwater flow control valves. b.Provide two switches for each boiler. One switch set at 20 psi above the minimum allowable operating air pressure as an alarm, and a second switch set at 10 psi above the minimum allowable operating air pressure as a burner interlock. c.V.

Alarm types shall include: high high, high, low, low low, bad input from I/O, alarm disable, off scan, deadband, change of state, open, close. Support at least three priorities for each alarm type: high, medium, low. b.Message enabling and disabling must be controlled at the block level. The system must be capable of sending messages based on the following events: an operator event occurs, process database event occurs. In addition to alarms, the following types of blocks must be able to generate messages that report to any transactions to and from the hardware: digital input, digital output, digital register, analog output, analog register, text. c.The system must generate applications messages that describe database-related activity or operator entry. These messages shall be logged to alarm areas. Types of messages include: operator changes a process value, loads process database, logs into the system; any recipe upload, download or save condition; send information from a VBA script to all enabled alarm destinations; send a message from the database to all alarm destinations. d.The system shall provide a means for placing an alarm message in one or more of the following locations: alarm summary display, alarm printer, alarm message file on disk, alarm history window. e.Alarm messages shall be independently user-configurable as to what information is provided and its sequence within the message. The following shall be available choices: time of the alarm occurrence, name of tag causing the alarm, engineering units value, descriptor text assigned to the tag, engineering units of the tag. f.When a new alarm condition is detected, an alarm message will be generated. If the alarm condition code text for the block is on the current display, then the text will flash until the alarm is acknowledged. Alarm acknowledgement will be performed from the keyboard or with the mouse and shall require no more than one keystroke or mouse click. The software shall include the following capabilities: alarm suspension which allows the user to specify digital tags that, when closed, cause alarms not to be generated for alarm conditions; re-alarm time which allows the system to re-generate an alarm after a user-configurable amount of time; alarm delay time which allows the user to specify a period of time for which an alarm condition must remain before an alarm is generated; close contact on alarm which allows user to specify digital tags that become closed when certain alarm conditions occur or reopened under certain conditions to allow operation of audible and visual alarms in the plant. g.Provide an alarm summary display as a dynamic link within the graphics package. This must show a list of the pending alarms in the system. As new alarms are detected, entries are made to the display list. Placement of alarm information and color codes shall be configurable. Alarms can be acknowledged from the summary display either individually or for all alarms in the queue. 13. Archiving and Reporting: a.Provide facility for automatically collecting, storing and recalling data. Recalled data shall be made available to a trend display program, a report generation program and to user-written programs. b.Store data in Windows-compatible files in compressed format. Entries containing time, name, value and status will be made in the file whenever the real-time value exceeds the previously stored value by a user-supplied deadband limit. A deadband value of zero will cause an entry in the file each time the real-time value is examined. Files shall be organized according to time and will contain values for multiple, named variables. The files can be placed on the hard disk or floppy disk. Provide a mechanism for on-line maintenance and automatic purging of files. c.The data to be collected by the archiving program will be identified through an interactive, menu-based configuration. The user will enter the tag name, collection rate, and data compression deadband value. Collection rates shall be selectable: 1 second, 2 seconds, 10 seconds, 20 seconds, 30 seconds, 1 minute, 2 minutes, 10 minutes. d.The operator shall be able to recall archived data from the disk to be displayed in graphic format along with real-time data. The display of archived data shall be user-configurable. It shall be possible to configure objects in graphic displays that, when selected, fetch pre-defined historical trend data from disk and display it to the operator. Attributes of pens shall be editable during run-time. e.The historical trend display shall be made up of the following components: 1)Pen Group: Configuration shall be used to define the particular tag names to be displayed. Along with tag names, pen color, marker style and engineering units may be defined. 2)Time Group: Configuration shall be used to define the time period over which the archived data is to be displayed. 3)Legend Group: Configuration shall be used to define the legend parameters for a historical display. Both a primary and alternate legend may be displayed. f.The display shall support unlimited variables to be displayed on the same time/value axis simultaneously. For each entry in the display list, the operator will be able to assign a given tag name and marker to a particular line color selected from palettes of unlimited colors. The operator may also enter display engineering units ranges to cause scaling of the display. Support shall be provided for multiple, different y-axis engineering units to be displayed as appropriate. g.The display shall have two fields of view. The top portion of the screen shall be the graphic field and will display the values of the variables (y-axis) against time (x-axis). It will also contain labels for the axes and graphs. The bottom portion of the screen shall be user-configurable to display information, such as node-names, tag names, and descriptors, pertaining to the tags in the trend display. h.The trend object shall allow for bi-directional trending and scrolling. A movable, vertical line will act as a time cursor on the display. The date, time and values of the trends corresponding to that time will be displayed in the bottom portion of the screen. The grid of the trend object shall be scrollable. The trend shall be shifted forward or backward in time by clicking on the right/left buttons. New data shall be fetched from the historical file as appropriate. The ability to display historical data with current data on the same chart must be supported. A transparent option for the trend must be selectable. The user shall be able to "zoom" on any section of the trend display by "cutting" that section with the mouse. The software will automatically re-scale both the y-axis and the time axis and will fetch the appropriate data for the time period selected. The trend object must have a refresh rate selectable in 0.1 second increments from a minimum of 0.10 seconds to a maximum of 1800 seconds. i.The trend display shall be printable to a black and white or color printer via the standard MS Windows NT print manager. 14.Event Scheduling: a.The system shall support a scheduler with time-based printing of reports. b.The system shall allow for scheduling of the following time-based printing of reports: Hourly, shift, daily, monthly, yearly. 15.Security Management: a.Provide a user-based security system which, when enabled, must allow for the creation of users with certain rights and/or privileges. These rights must include the ability to run any combination or all of the applications in the data acquisition system. The ability to allow or disallow users access to change values, such as set points and control setups, on an individual tag basis shall be supported. b.Groups of users, such as operators or supervisors, can be created and granted rights. All users assigned to a group obtain the rights of the group although they are tracked by the system by their individual ID. Individual members of a group may be also assigned additional rights. c.The system must support a tie to Windows NT security. When user-based security is enabled, an audit trail will be generated in the system, which will tag every operator action with a user ID. d.The system must support at least twenty separate security areas, assignable on a per-tag basis. Each tag can be assigned all of the available security areas, none of the available security areas, or up to three individual security areas. Only users with clearance for those security areas shall have the ability to change parameters. Security area names may be up to twenty characters in length. e.The following functions must be supported: enable/disable user-based security; define users, passwords and login names; define groups to which users may belong; define security paths; define user and/or group rights/privileges; define security area names; define system auto-start user. f.The ability to lock an operator or other user into the runtime graphics environment shall be provided. Disabling any combination of the following shall be supported, as configured by the user: starting other applications; switching to other applications that may be running; exiting from the system; restarting the computer using
