Sheet 2: Conversion Factors

Energy and Emissions Conversions

Energy Conversions:

·         Conversion from Btu Higher Heating Value (HHV) to Btu Lower Heating Value (LHV) multiply by 0.91 for natural gas

·         Conversion from lb/MMBtu HHV to lb/MMBtu LHV multiply by 1.099 for natural gas

·         HHV Natural Gas 1,030 (Btu/scf), 21,980 (Btu/lb)

·         LHV Natural Gas 937 (Btu/scf), 20,000 (Btu/lb)

·         1 horsepower hour (hp-hr) = 2,545 Btu

·         1,000,000 Btu = 1 MMBtu = 392.9 hp-hr

·         1 kW = 3,413 Btu per hour (Btu/hr)

·         1 MMBtu/hr = 293 kW

·         1 kWh = 3,413 Btu

·         1 MMBtu = 293 kWh

·         0.7457 kW = 1 hp

·         1 kW = 1.341 hp

Emissions Conversions:

Combustion Turbines and Microturbines

Criteria pollutant emissions for turbines are typically presented as parts per million (ppm) reported at 15 percent O2 in the exhaust stack. The eCatalog is requesting emissions data in an output based format (lb per MWh) in order to facilitate a common comparison among technologies and systems.

Recip Engines

Criteria pollutant emissions for engines typically are reported as g/hp-hr. The eCatolog is requesting emissions data in an output based format (lb per MWh) in order to facilitate a common comparison among technologies and systems. The efficiency of engines is described in terms of percent efficiency or brake specific fuel consumption (BSFC) in Btu/hp-hr.
