| 21. | The study implied that this increase in efficiency was due to fuel density, viscosity, and heating values of the fuels.
|
| 22. | Heavier hydrocarbons such as ethane ( C2H6 ), propane ( C3H8 ), and butane ( C4H10 ) increase its heating value.
|
| 23. | Temperature, pressure and heating value compensation must be made to measure actual amount and value of gas moving through a meter.
|
| 24. | :In the conditions found in a residential or commercial heating furnace, Nitrogen will not react and therefore has no heating value.
|
| 25. | Typically, blast furnace gas has a heating value of less than 100 Btu / scf, one-tenth of that of natural gas.
|
| 26. | This increases the efficiency ( energy delivered into the building vs . heating value of gas purchased ) to over 90 %.
|
| 27. | Depending on the intended use of the gas, tar can be beneficial, as well by increasing the heating value of the gas.
|
| 28. | Soils with heating values greater than 2, 000 Btu / lb require blending with cleaner soils to dilute the high concentration of hydrocarbons.
|
| 29. | The total efficiencies of cogeneration incinerators are typically higher than 80 % ( based on the lower heating value of the waste ).
|
| 30. | Flue gas condensation may cause the heat recovered to exceed the Higher Heating Value, which typically results in efficiencies less than 100 %.
