SRI/USEPA-GHG-VR-27 September 2003 area is about 1.2 watts per square foot. The facility electric demand is never expected to drop below 200 kW in this store. The three-phase 480 volt power generated by the microturbine is wired directly into the store's 480-volt main panel. This CHP unit was integrated with a 20,000-cfm Munters Drycool air- handling unit previously installed at the Waldbaums. The Munters is the primary source of space heating, air conditioning, and air-dehumidification at the store. Recovered heat from the Capstone 60 CHP System is used to supplement the Munters' primary functions of heating the main sales areas of the store, and air dehumidification. The CHP system can provide heat to either the PG coil in the supply air stream that provides space heating in the winter or the PG coil that preheats the air entering the direct-fire burner that regenerates the desiccant wheel. VERIFICATION DESCRIPTION Testing commenced on June 4, 2003, and was completed on June 20, 2003. The testing included a series of controlled test periods in which the GHG Center intentionally modulated the unit to produce electricity at nominal power output commands of 15, 30, 45, and 60 kW. Demand for space heating and dessicant regeneration was low during the testing period due to the mild weather. The PG was, therefore, manually directed to the Munter's space-heating coil during each of the controlled test periods. This was done to maximize the heat demand on the CHP system and verify CHP performance under periods of high heat demand. The controlled tests at the 30 and 60 kW power command points were also repeated with the Unifin heat exchanger damper open (heat recovery bypass mode) to evaluate the impact of heat exchanger back-pressure on microturbine performance. The controlled test periods were followed by 14 days of extended monitoring to verify electric power production, heat recovery, power quality performance, and efficiency during an extended period of normal site operations. The classes of verification parameters evaluated were: • Heat and Power Production Performance • Emissions Performance (NOx, CO, THC, CO2, and CH4) • Power Quality Performance Evaluation of heat and power production performance includes verification of power output, heat recovery rate, electrical efficiency, thermal efficiency, and total system efficiency. Electrical efficiency was determined according to the ASME Performance Test Code for Gas Turbines (ASME PTC-22) and tests consisted of direct measurements of fuel flow rate, fuel lower heating value (LHV), and power output. Heat recovery rate and thermal efficiency were determined according to ANSI/ASHRAE test methods and tests consisted of direct measurements of heat-transfer fluid flow rate, differential temperatures, and specific heat of the heat transfer fluid. Ambient temperature, barometric pressure, and relative humidity measurements were also collected to characterize the condition of the combustion air used by the turbine. The evaluation of emissions performance occurred simultaneously with efficiency testing conducted during the controlled test period. Pollutant concentration and emission rate measurements for nitrogen oxides (NOX), carbon monoxide (CO), total hydrocarbons (THC), carbon dioxide (CO2), and methane (CH4) were conducted in the turbine exhaust stack. All test procedures used in the verification were U.S. EPA reference methods recorded in the Code of Federal Register (CFR). Pollutant emissions are reported in two sets of units – as concentrations in parts per million volume, dry (ppmvd) corrected to 15-percent oxygen (O2), and as mass per unit time (lb/hr). The mass emission rates are also normalized to turbine power output and reported as pounds per kilowatt hour (lb/kWh). S-3PDF Image | Environmental Technology Verification Report
