® WorleyParsons <br /> resources&energy <br /> demonstrated using software simulation, but will include sufficient hardware testing to <br /> confirm proper system integration. A test procedure will be developed by the system <br /> supplier to support the factory acceptance test. <br /> 5.4 Local Controls <br /> DCS start/stop functions will not be provided for self-contained components/equipment <br /> packages that do not require constant operator control or intervention (e.g., lubricating oil <br /> pumps, sump pumps, vent fans, etc). <br /> Hard wired local controls for equipment will be limited to hand-off-auto switches in the <br /> MCC's for 480 volt motors and those provided by the equipment/skid manufacturer. <br /> 5.5 Analytical Equipment <br /> 5.5.1 Continuous Emissions Monitoring System <br /> A continuous emissions monitoring system (CEMS) and data acquisition and reporting <br /> system (DARS) will be provided for the HRSG trains in accordance with the air permit. <br /> The CEMS will consist of sampling devices connected via sample lines to emissions rack <br /> mounted analytical measurement devices and CEMS control equipment located in the <br /> CEMS enclosure near the base of one of the stacks. <br /> Adequate rack space will be provided to allow future analyzers if required. <br /> The building containing the CEMS equipment will have an exterior weather shield to <br /> protect the bolted racks, gas cylinders and regulators for connection of the calibration <br /> gases. <br /> The CEMS will be controlled by a PLC and will monitor NOx, CO, 02,and NH3. <br /> Inputs for fuel flow, power generation, and all other required process conditions will be <br /> hard wired from the plant DCS. Emissions will be calculated based on plant fuel flows, <br /> analyzer readings, and surrogate calculations based on fuel analysis. <br /> The primary operator interface with the CEMS will be through a personal computer <br /> workstation (PC) located in the CEMS building. The PC will provide operator access via a <br /> Windows environment to acknowledge alarms, retrieve data, and generate all required <br /> emissions reports and will include exceedance/fault codes as appropriate. System reports <br /> will be modifiable by site personnel, and emission alarms will be adjustable through the PC <br /> interface. All appropriate equations and coefficients used by the systems will be capable of <br /> being modified by authorized plant personnel (via password protection). <br /> The CEMS hardware and reporting package software will meet the requirements of <br /> applicable permits. System reports will be able to include a daily summary of the average <br /> plant generation in megawatts, the average fuel flows, and any other plant data available to <br /> Lodi Energy Center 3.5 -5 LEC AFC <br /> 071608 Rev.A <br />
