Why is the lower heating value important?

The lower heating value (LHV) or higher heating value (HHV) of a gas is an important consideration when selecting a gas engine or CHP plant. Gas engines efficiency is typically quoted based upon the LHV of the gas. Whenever a hydrocarbon fuel is burned one product of combustion is water.

What does LHV mean?

LHV

Acronym	Definition
LHV	Low Heating Value
LHV	Lady Health Visitor (health care)
LHV	Lock Haven, Pennsylvania (Airport Code)
LHV	Lower Hudson Valley (New York)

Is natural gas HHV or LHV?

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

What is lower heating value?

The lower heating value (also known as net calorific value) of a fuel is defined as the amount of heat released by combusting a specified quantity (initially at 25°C) and returning the temperature of the combustion products to 150°C, which assumes the latent heat of vaporization of water in the reaction products is not …

What is the importance of calorific value of a fuel?

What is Calorific Value and Why is It Important? Calorific value is the energy or amount of heat produced as a result of the complete combustion of a unit volume of the substance. It is important as it gives the value of fuel or food in numbers which can be calculated with a formula.

How do you calculate LHV to HHV?

Under this formula, the relationship between the lower heating value of a fuel and the higher heating value of that fuel is: LHV = HHV – 10.55(W + 9H) Where: LHV = lower heating value of fuel in Btu/lb, HHV = higher heating value of fuel in Btu/lb, W = Weight \% of moisture in fuel, and H = Weight \% of hydrogen in fuel.

What does HHV mean?
