Description

DEPARTMENT OF VETERANS AFFAIRS MEDICAL CENTER NORTHAMPTON BOILER PLANT SERVICE STATEMENT OFWORK Inspection, Testing and Calibration Boiler Plant Burners, Controls, Instruments and Data Management Introduction: This Statement of Work describes all requirements for the inspection, testing, calibration, and combustion tuning of the boiler plant burners, controls and instruments by qualified technicians Boiler plant safety, reliability, efficiency and equipment longevity are paramount concerns of VAMC management. Malfunctioning burners or controls can cause catastrophic events resulting in injuries and death and massive property damage. Inaccurate or inadequate data management and monitoring systems can fail to warn of unsafe or inefficient performance. Regular inspections, testing and calibration by expert technicians are an essential part of a program to address these concerns. Appendix A, attached, lists the specific equipment models and ratings of each boiler. A separate Statement of Work document covers the inspections of the boilers and feed water Deaerator by Qualified Professional Inspectors. Technician Qualifications: Technicians shall have completed at least a one-year trade school and have five years successful experience in this field. The experience shall be largely with institutional and industrial boiler plants similar in design to the VAMC plant. The VAMC facility manager/engineer may define and accept equivalent qualifications. Technicians shall demonstrate familiarity with and ready access to the current versions of the following references: 1.NFPA 85, Boiler and Combustion Systems Hazards Code. 2.VHA Boiler Plant Safety Device Testing Manual, 3rd Edition. Technicians shall be equipped with portable electronic flue gas analyzers and other test instruments necessary for the required tests and calibrations, all calibrated within one month of the site visits. This facility has programmable digital controls; all technicians must be capable of programming the controls and have the appropriate hardware and software for this. Inspection, Testing and Calibration Requirements: Technicians shall perform inspection, tuning, testing, calibrating, and adjustments of burners and boiler and boiler plant controls as specified below. This shall be done every six months in accordance with the schedule provided by VAMC. VAMC may extend the schedule for burners in limited service. Two (2) Semi-annual services for each Boiler and Two (2) Tune-Up Services for each Boiler are specifically covered by this service. Instrumentation, monitoring and data management systems as listed below shall be calibrated every six months. Provide at least a two week notice to the Contracting Officer's Representative (COR) prior to performing the work. Work cannot be scheduled during heavy steam load periods. Only one boiler at a time can be out of service for the inspection, testing and calibration procedures. Work must be conducted when the COR or a designee is available on site to monitor the work. VAMC will have the boilers that are to be serviced prepared for the technicians upon their scheduled arrival. This includes having the boilers clean of soot and loose scale; fully warmed and at normal steam pressure. All inspections, testing and calibrations shall comply with: 1.The recommendations and requirements of VHA Boiler Plant Safety Devices Testing Manual, 3rd Edition. 2.The written recommendations of the equipment manufacturers. 3.The requirements and recommendations of NFPA 85 Boiler and Combustion Systems Hazards Code including applicable appendices. 4.Burner performance requirements in this document. A summary of the work is as follows: 1.Review boiler plant log sheets and alarm and trouble reports. 2.Review records that show combustion performance (flue gas oxygen and carbon monoxide). 3.Perform overall visual inspection of systems. Verify that systems comply with referenced codes and VAMC requirements stated in this contract. 4.Test and record the operation and set points of all burner/boiler safety interlock devices. Refer to list below. Verify that the set points and operating points are within approximately 20% of normal operating parameters. Make adjustments as necessary and record the new settings. The operation of a device must result in burner shutdown and/or proper alarm operation. 5.Operate burner(s) on each fuel from low fire to high fire and back to low fire in at least four increments and record combustion performance (flue gas oxygen, carbon monoxide, NOX where applicable), fuel train pressures, atomizing train pressures, burner pressures, stack temperatures, boiler steam output. 6.Compare the combustion performance data with VAMC requirements (see below) and previous readings. If necessary, make adjustments to the fuel flow and combustion air controllers, control valves and dampers to obtain the required performance. Record the new performance data. 7.Verify accuracy of instrumentation listed below. Verify that all devices are properly selected for the application in terms of type, size, set point range, performance, code approval. Calibrate all instruments that are not within manufacturer's specifications for accuracy. 8.Immediately inform COR of any recommended repairs or modifications. List of interlocks, safety devices, and gauges to be inspected, tested, or calibrated Semi Annually on each boiler/burner: 1.Low-water cutoff (slow drain) 2.Fire each boiler and the pilot on the alternate fuel for 1 hour 3.Low-water cutoff shunt switch 4.Auxiliary low-water cut-off (slow drain) 5.Auxiliary low-water cut-off shunt switch 6.High-water alarm 7.Low-water alarm 8.High-steam pressure cut-out (recycle) 9.High-steam pressure cut-out (non-recycle) 10.Steam safety valves (raise boiler pressure until valve pops). 11.Flame scanner 12.Check gas vent for leaks 13.High-gas fuel pressure cut-off 14.Low-gas fuel pressure cut-off 15.Gas fuel safety shut off valves proof of closure 16.Leak test gas fuel safety shut off valves 17.High-fuel oil temperature cut-off (heated fuel) 18.Low-fuel oil temperature cut-off (heated fuel) 19.Low-atomizing pressure for fuel oil 20.High-fuel oil pressure cut-off Low-fuel oil pressure cut-off 21.Leak test fuel oil safety shut off valves 22.Check operation of Liquid Petroleum Gas pilot 23.Low-pilot gas pressure cut-out 24.Forced draft fan motor interlock 25.Forced draft fan damper wide open for purge 26.Boiler outlet damper wide open for purge 27.Purge air flow interlock 28.Timing for pre-purge 29.Timing for post-purge 30.Igniter timing 31.Low fire position interlock 32.Combustion air interlock 33.Main flame out; i.e., time to close valves 34.Ignition flame out; i.e., it is time to close valves 35.Minimum igniter flame test 36.Scanner not sensing ignition spark 37.Low-oxygen alarm and/or cut-out 38.Pre-purge setting of flue gas recirculation damper 39.Fuel oil safety shut off valves proof of closure The Steam safety valves (accumulation test at high fire) will be completed on an annual basis.
