Inspection, Testing and Calibration Boiler Plant Burners, Controls, Instruments and Data Management (To be performed in addition to maintenance above) 1. Introduction: A. 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. B. This "Statement of Work" describes the requirements for the inspection, testing and calibration of the boiler plant burners, controls and instruments by qualified technicians. 2. Technician Qualifications: A. 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. B. Technicians shall demonstrate familiarity with and ready access to the current versions of the following references: NFPA 85, Boiler and Combustion Systems Hazards Code. VHA Boiler Plant Safety Device Testing Manual, 2nd Edition. C. 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. The technicians must be capable of programming digital controls and have the appropriate hardware and software for this. 3. Inspection, Testing and Calibration Requirements: A. 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 a schedule provided by VAMC. VAMC may extend the schedule for burners in limited service. B. Instrumentation, monitoring and data management systems as listed below shall be calibrated every six months. C. Provide at least two weeks notice to the Contracting Officer's Technical Representative (COTR) 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 COTR or his/her designate is available on site to monitor the work. The COTR is: Jim Coyle ext 2210. D. 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; steam exhaust silencer system operable; all boiler, burner and fuel train pressure gages and thermometers calibrated. E. VAMC will comply with any other requirements of the test personnel that are considered reasonable by VAMC and have been presented in writing at least two weeks prior to the scheduled testing. F. The inspections, testing and calibrations shall comply with: 1) The recommendations and requirements of VHA Boiler Plant Safety Devices Testing Manual, 2nd 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. G. 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 six 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 COTR of any recommended repairs or modifications. H.
