• Lower heating value — The lower heating value (also known as net calorific value , net CV , or LHV ) of a fuel is defined as the amount of heat released by combusting a specified quantity (initially at 25 °C or another reference state) and returning the temperature of …   Wikipedia

• Net (Lower) Heating Value — (NHV)   The potential energy available in a fuel as received, taking into account the energy loss in evaporating and superheating the water in the fuel. Equal to the higher heating value minus 1050W where W is the weight of the water formed from… …   Energy terms

• Lower (Net) Heating Value —   The lower or net heat of combustion for a fuel that assumes that all products of combustion are in a gaseous state. (See Net Heating Value below.) …   Energy terms

• Heating Value —   The amount of heat produced from the complete combustion of a unit of fuel. The higher (or gross) heating value is that when all products of combustion are cooled to the pre combustion temperature, water vapor formed during combustion is… …   Energy terms

• Higher heating value — The higher heating value (HHV;also known as the gross calorific value or gross energy) of a fuel is defined as the amount of heat released by a specified quantity (initially at 25 °C) once it is combusted and the products have returned to a… …   Wikipedia

• Higher Heating Value — (HHV)   The maximum heating value of a fuel sample, which includes the calorific value of the fuel (bone dry) and the latent heat of vaporization of the water in the fuel. (See moisture content and net (lower) heating value, below.) …   Energy terms

• Fuel efficiency — is a form of thermal efficiency, meaning the efficiency of a process that converts chemical potential energy contained in a carrier fuel into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per… …   Wikipedia

• Brake specific fuel consumption — (BSFC) is a measure of an engine s efficiency. It is the rate of fuel consumption divided by the power produced. BSFC is specific for shaft engines such as reciprocating engine. The BSFC Calculation (in metric units) To calculate BSFC, use the… …   Wikipedia

• Fuel economy-maximizing behaviors — (also known as green driving) describe techniques that drivers can use to optimize their automobile fuel economy. The energy in fuel consumed in driving is lost in many ways, including engine inefficiency, aerodynamic drag, rolling friction, and… …   Wikipedia

• Space heating — is the heating of a space, usually enclosed, such as a house or room. A space heater keeps the air and surroundings at a comfortable temperature for people or animals, or even plants in a greenhouse. Space heating generally warms a small space,… …   Wikipedia
