about 1,000 BTU/ft3. See related link. It is not exact because natural gas composition varies. A richer gas would have a higher heating value. The cubic feet (ft3) is often abbreviated scf, or standard cubic feet, measured at 60 deg F and 14.7 psia. Future market gas prices at quoted in $/mmBTU or dollars per million BTU (currently around $4/mmBTU), equivalent to $4.00/Mscf. See related site.
Natural gas is used for heating and generating electrical energy
They are more enviromental friendly then coal or oil. Natural gas burns cleaner than heating oil, and does not leave product, like ash, behind. Has high heating value of 24,000 Btu per pound.
heating boilers, gas cookers
There are many reason why natural gas is usually a cheaper option for heating when compared to heating with electricity. The biggest reason is heating with therms is cheaper than kilowatts.
Primarily a heating fuel.
Natural gas comes out of the ground. As a product of nature, natural gas is not the same from country to country. Methane is the main component, but metane's percentage can vary between 80% and 95%. Others hydrocarbons' percentage (for example ethane, propane, butane etc) also vary. Since heating value depends on the percentage of the hydrocarbons, heating value also varies.
Natural gasses are a by-product of oil production. Where you will find oil, you will have natural gas. Commercially, natural gasses are used for heating, cooking, and producing of electricity.
gas is converted into electricty, than that is used for heating.
It will vary somewhat with the composition of the natural gas, but roughly 133 cubic ft of natural gas has the same heat value as 1 gallon of #2 heating oil. Minutes do not enter into the calculation
yupe,its efficiency=Q/heating value of fuel
Natural gas is used for heating and generating electrical energy
Oil central heating tends to be more expensive when compared to gas central heating as the price for heating oil tends to be higher when compared to natural gas. The price of heating oil also tends to be more volatile than natural gas.
Methane. It has the chemical formula CH4 which is why it is called this. Common heating gas is natural gas. The main ingredient of natural gas is methane.
