Burn natural gas cheap or burn cheap, how to charge natural gas
Low calorific value of natural gas is about 36.2MJ/ standard cubic meters, 1 cubic meters of natural gas in the currency unit of, the 1MJ heat generated 124.4/36.2 = 3.42 monetary unit /MJ.1 kwh of electricity to produce a heat of 1000 x = 3.6MJ, then produce 1MJ heat costs 22.6/3.6 = 6.27 currency unit /MJ.Taking into account the minimum heat efficiency of the heater water heater is 84% ("domestic gas rapid water heater energy efficiency limits and energy efficiency rating"), the use of natural gas water heating 1MJ heat = 3.42/84% = 4.07.So as a water heater, natural gas is cheaper than electricity.If used to boil water, household appliances, the average thermal efficiency of 43% - 52%, natural gas is not necessarily cheaper than electricity. As for how much money should be a place a price, this I do not know
1 meters fand natural gas prices in the 2.9~3.2 yuan / m of natural gas in different regions of fand, different prices.Electricity prices in the 0.50~0.8 yuan / degree, the price of 11.09 degrees between 5.5~8.8 yuan.It is obviously cheaper to use natural gas, the use of natural gas costs about 45% of electricity.
Produce 1 kwh heat = 1000 joules / sec x 3600 seconds =3600000 = 857 thousand Joule card.It is 1 meters: gas heat generated fand = 11.09 electrically generated heat (9500/857 = 11.09)
Burning natural gas than burning natural gas electricity is cheap, charge about 3 yuan / m fand.The use of natural gas and electricity is as follows:Gas calorific value is 9 million 500 thousand / M fand card.
