What is the LHV of natural gas?

Fuel	Density	Lower Heating Value (LHV) (Net Calorific Value – NCV)
@0°C/32°F, 1 bar
Methane	0.716	13.9
Natural gas (US market)*	0.777	13.1
Town gas

What is the calorific value of wood in MJ kg?

Oven-dry woody biomass typically has a calorific value of 18-21 MJ per kg on a dry basis (this is the gross calorific value). Most fuels are not oven dry when burnt and the water in the wood must be evaporated, detracting from the extractable energy* (or net calorific value).

What is the calorific value of wood in KJ kg?

Calorific value of wood is 18000 kj/kg.

What is the calorific value of wood fuel?

Typical calorific values of fuels

Fuel	Net CV by mass	Energy density by volume
Wood chips (30% MC)	12.5	3,100
Log wood (stacked – air dry: 20% MC)	14.7	5,200-7,400
Wood (solid – oven dry)	19	7,600-11,400
Wood pellets (10% MC)	17	11,000

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.

Is natural gas HHV or LHV?

Lower Heating Value A rule of thumb for natural gas is HHV = LHV x 1.11.

How many KW is a kg of wood?

Each kilogram of (EN Standard) dry wood contains 5.14 kWh of “potential heat” so 1 kWh of energy is contained in (1/5.14=) 0.195 kg of wood.

Which wood has highest calorific value?

The experimental values of the highest calorific value in terms of BDH are (mJ/kg): 19.40… 21.20 – for wood with natural bark content; 18.9…23.6 – for bark; 20.8±0,5 – for coniferous species (including pine – 20.90±0.30); 20.0±0.7 – for hardwood (including alder and aspen – 19.90±1.00; for birch bark – 23.6).

What is the difference between HHV and LHV?

We refer to HHV when liquid water exists in the combustion products and LHV when water vapor exists in the combustion products. Numerically the difference between the two values is the latent heat of vaporization times the mass of water produced by the combustion process.

What is heating value of natural gas?

Heat Values of Various Fuels

	Heat value
Crude oil	42-47 MJ/kg
Liquefied petroleum gas (LPG)	46-51 MJ/kg
Natural gas	42-55 MJ/kg
Hard black coal (IEA definition)	>23.9 MJ/kg

How much energy is in a kg of wood?

In fact, 1 kg of wood gives 3500 (Kcal/kg) × 0.08 (thermal energy yield) = 280 Kcal; 1 kg of wood processed into charcoal (carbonization yield 20 percent) gives = 1 × 0.20 × 0.28 (thermal energy yield) × 75.00 (Kcal/kg) = 420 Kcal.
