## What is the LHV of propane?

Fuel | Density | Lower Heating Value (LHV) (Net Calorific Value – NCV) |
---|---|---|

@0°C/32°F, 1 bar | ||

Pentane | 0.63 | 12.60 |

Petroleum naphtha* | 0.725 | 12.47 |

Propane | 0.498 | 12.88 |

**What is the HHV of propane?**

The HHV The standard heat of combustion of propane is C3H8(g) + 5 O2(g) → 3 CO2(g)+ 4 H2O (l) ΔHm = -2219.2 kJ[7] = HHV = ΔH1 (1) This is the process which yields the HHV, because the fuel is burned and the combustion products are cooled to 25 oC, removing all heat resulting from the condensation of water in the …

**How do you calculate LHV of fuel?**

Heating value of gas fuels is measured by Junker’s gas calorimeter. Hence, LHV = HHV- m hfg, where m is mass of water formed by combustion (kg) and hfg is latent heat of vaporization of water, kJ/kg.

### How many Btus does ethane have?

Gas | Gross Heating Value | Net Heating Value |
---|---|---|

(Btu/ft3) | (Btu/lb) | |

Ethane – C2H6 | 1783 | 20295 |

Ethyl alcohol saturated with water | 1548 | |

Ethylene | 1631 | 20525 |

**What is the difference between LHV and HHV?**

HHV stands for higher heating value while LHV stands for lower heating value. The key difference between HHV and LHV is that HHV can be determined by bringing all the products of combustion back to the original pre-combustion temperature while allowing any produced vapour to condense.

**How many BTU is a gallon of propane?**

91,600 BTU

Of course, a cubic foot is a larger quantity than a gallon. To get a better comparison, you need to convert the BTU figure for propane into BTU/gallon. That gives: 91,600 BTU/gallon for propane.

## How many BTUs does a gallon of propane produce?

91,500 BTUs

Propane has 91,500 BTUs per gallon. 1.52 gallons equals the heat of one gallon of oil. Electricity has 3,413 BTUs per kilowatt hour (kwh).

**Should I use HHV or LHV?**

For simply benchmarking part of a reaction the LHV may be appropriate, but HHV should be used for overall energy efficiency calculations if only to avoid confusion, and in any case, the value or convention should be clearly stated.

**What is the difference between HHV and LHV?**

### How many BTUs are in a gallon of propane?

91,500 British thermal units

Let’s walk through how to do this. Liquid propane (LP) has 91,500 British thermal units (BTUs) per gallon. Electric heat has 3,413 BTUs per kilowatt hour (kWh) or 1,000 watts per hour.

**How many BTUs are in a cubic foot of propane?**

2,516 BTUs

BTUs. One cubic foot of propane = 2,516 BTUs. One cubic foot of natural gas = 1,030 BTUs.

**Why is LHV used instead of HHV?**

## What does LHV stand for?
