Description:
The Greenhouse Gas Technology Center (GHG Center), one of six verification organizations under the Environmental Technology Verification (ETV) program, evaluated the performance of the Parallon 75 kW Turbogenerator (Turbogenerator) with carbon monoxide (CO) emissions control system offered by Honeywell Power Systems, Inc. of Albuquerque, New Mexico. The Turbogenerator is a compact, natural-gas-fired microturbine able to produce approximately 75 kW of 3-phase alternating current electricity at 275 volts that can be connected directly to both the customer and existing transmission and distribution lines. The power electronics allow the system to operate in parallel with the utility grid to provide emergency backup power, peak shaving, baseload generation, or cogeneration (combined heat and power generation). Emissions tests were conducted at 75 and 50% load because CO emissions were not detected at 100 and 90% loads during earlier tests of the unit without CO control. Tests also included determination of electrical power output and efficiency. The verification test was conducted at a commercial office facility operated by the University of Maryland, College Park. The Turbogenerator was connected to the electric grid system and provided about 30% of the electricity requirements for the 55,000 square foot office building. For the load tests, temperature ranged from 52 to 56 degrees F, and relative humidity was approximately 91%. Power delivery by the Turbogenerator with CO control was consistent with that delivered without CO control. Electrical efficiency with CO control was approximately 2% lower than without CO control as a result of higher fuel consumption rates. CO emission rates were below the lower detection limit of the sampling system (approximately 2 ppm) with CO control. NOx emissions were not significantly changed by use of the CO control system. Emissions of hydrocarbons increased slightly at 50% power. Emissions of CO2 increased by approximately 2% at 75% power and 13% at 50% power with CO control. Emissions of total hydrocarbons (THCs) also increased at low load. Increases in CO2 and THC emissions are likely related to the higher fuel consumption rates that occurred during these tests.
