Description:
The Environmental Technology Verification report discusses the technology and performance of the IR PowerWorks 70kW Microturbine System manufactured by Ingersoll-Rand Energy Systems. This system is a 70 kW electrical generator that puts out 480 v AC at 60 Hz and that is driven by a gas turbine fueled by natural gas at 35 psig. It has a gas compressor for boosting low pressure input gas, if necessary. The PowerWorks 70kW can supply heat in addition to electricity through a subsystem that recovers heat from the turbine exhaust gas. The performance verification tests were conducted for 7 days at the Crouse Community Center, a 60,000 square foot skilled nursing facility in Morrisville, NY. At full load, electrical output averaged 50.6 kW at 25.3% efficiency. At full load, the system supplied a maximum of 143,500 Btu/hr of recovered heat at a thermal efficiency of 21.0%, making the total combined heat and power efficiency 46.3%. The average electrical output characteristics over the 7-day test period were 60.001 Hz, 494.75 v, 67.5% power factor, and total harmonic distortion of 4.76% in current and 2.05% in voltage. At full load, the system emissions of nitrogen oxides, carbon monoxide, total hydrocarbons, methane, and carbon dioxide were 0.0000467, 0.0000209, 0.0000448, less than 0.0000493, and 1.60 lb/kWh, respectively.
