KWH in one cu Mtr of natural Gas

Re: KWH in one cu Mtr of natural Gas There is no exact value, because the density of gas depends on additional factors. You can get a fairly good estimate though. The Physics Factbook lists energy density of Natural Gas at about 34.6 to 38.3 megajoule per cubic meter. That is about 9.6 to 10.6 kilowatt hours

Ideal Fuel

Natural Gas is as close as you can get to an ideal fuel. It requires minimal processing before use and it has high calorific value. Due to its gaseous state, it mixes with oxygen easily for more efficient combustion. By producing relatively few pollutants, it also helps to reduce emissions that can contribute to the greenhouse effect.

Natural gas price, market and curtailment information

FortisBC uses the Higher Heating Value (HHV) of the natural gas in the conversion formula. The HHV can be defined as the total heat obtained from combustion of a specified amount of fuel and its stoichiometrically correct amount of air, both being at 60 F when combustion starts, and the combustion products being cooled to 60 F before heat release is measured.

CHAPTER 1 INTRODUCTION

Anthracite Anthracite is a high rank coal used for industrial and residential applications. It has generally less than 10 percent volatile matter and a high carbon content (about 90 percent fixed carbon). Its gross calorific value is greater than 23 865 kJ/kg (5 700 kcal/kg) on an ash-free but moist basis.

Calorific value of fuels

The calorific value of fuels helps us to decide that which fuel is good for us. This is done by comparing the calorific values of fuels with each other. Usually, a fuel having higher calorific value is considered to be a good fuel. 1) Case of Hydrogen Gas Hydrogen gas has the highest calorific value of 150 KJ/g among all the fuels. So, hydrogen

Heat of combustion

The quantity known as lower heating value (LHV) (net calorific value (NCV) or lower calorific value (LCV)) is determined by subtracting the heat of vaporization of the water from the higher heating value. This treats any H 2 O formed as a vapor. The energy required to vaporize the water therefore is not released as heat.

Calorific Value

Therefore, the gross calorific value is always higher than the net calorific value. If the water remains in the exhaust gas as water vapor, the net calorific value is specified. But if the exhaust gases are cooled below the condensation point of water vapor (for example, in condensing boilers) the gross calorific value
