- RULE 433 - aqmd. gov
The WOBBE INDEX (WI) of natural gas is the higher heating value (HHV) of the natural gas, expressed as Btu per standard cubic foot, divided by the square root of the gas’ real relative density (RDreal), i e , WI = HHV RDreal 1 2
- AER Reporting Tool Help and Support Manual - South Coast Air Quality . . .
1 therm = 100,000 Btu 1 therm = 0 0000973 mmscf based on default HHV for natural gas (1,028 Btu scf)
- Enbridge Gas
Enbridge Gas provides no guarantee regarding gas composition or high heating value (HHV) for any specific delivery point It is the responsibility of the information user to ensure that the data meets the applicable regulatory requirements
- Boiler Natural Gas 5-20 MMBtu hr - South Coast Air Quality Management . . .
AQMD BACT limits for new boiler using natural gas with rating 5-20 MMBtu hr are 12 ppmv NOx @ 3%O2 and 100 ppmv CO @ 3% O2 This boiler is expected to meet current BACT limits

For non-standard fuels that are not listed in 40 CFR Part 60, Appendix A, Method 19, a constant F-factor and heating value may be used if the Facility Permit holder demonstrates to the Executive Officer that the natural gas, fuel oil, or other fuels have stable F-factors and gross heating values
- Understanding sCaQMd air QUality rUles for engines - SoCalGas
What size engines require a permit to operate? Anyone planning to install a new gas engine rated > 50 BHP must apply for a permit from the SCAQMD before installation What do i need to provide the sCaQMd to obtain a permit? ecific information about your engine and its use Permit application packages are available from the SCAQMD,
- Higher Calorific Values of Common Fuels: Reference Data
Higher Calorific Value (= Gross Calorific Value - GCV = Higher Heating Value - HHV) - the water of combustion is entirely condensed and the heat contained in the water vapor is recovered
- How to calculate the heating value HHV-LHV of natural gas?
By substituting the known values of carbon content, hydrogen content, and water content, you can calculate the HHV and LHV of natural gas What is the higher heating value (HHV) of natural gas? The HHV of natural gas is the maximum amount of heat released when it is completely combusted
