The net heating value will considering the evaporation of water formed in reaction of natural gas decomposition as follow
CnHm+(n+m/4)O2=nO2+m/2H2O
For Methane : CH4 we have
n=1 " number of carbon
m=4 " number of hydrogen
then: CH4+(1+4/2)O2
O2+2H2O=CH4+3O2=2H2O
Subtracting enthalpy of products from reactants to get enthalpy of decomposition
What else can I help you with?
What common heating gas is defined by the sumbols CH4?
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.
What is a natural gas with the formula CH4?
CH4 stands for methane.It is a neutral gas.
What is the equation for combustion efficiency of natural gas burning furnaces?
The equation for combustion efficiency of natural gas burning furnaces is typically calculated as: Efficiency = (Energy output / Energy input) x 100% where Energy output is the heat released by burning the natural gas, and Energy input is the total energy content of the natural gas fed into the furnace.
What gas do you use for gas cookers?
Natural gas is commonly used for gas cookers in households. It is a clean-burning fuel that is efficient for cooking and heating purposes. Safety precautions should be observed when using natural gas appliances.
Natural gas is a gas consisting of methane?
Natural gas is a fossil fuel composed mainly of methane and is used for heating, cooking, and electricity generation. It is colorless, odorless, and highly flammable.
Is the heating value of natural gas different in different countries?
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.
How many cubic feet of natural gas to equate to 1 gallon per minute of heating oil?
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
How is natural gas used for heating?
gas is converted into electricty, than that is used for heating.
How does oil central heating compare to gas central heating?
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.
What is BTU rating of natural gas?
For the purpose of gas rating 1040 btu's/ft3
What burns hotter oil or natural gas?
Natural gas burns hotter than oil. Natural gas has a higher heating value per unit volume compared to oil, making it a more efficient and hotter-burning fuel.
How much natural gas is required to produce 1 ton of steam?
On average, about 1050 cubic feet of natural gas is required to produce 1 ton of steam. This can vary depending on the efficiency of the boiler and the heating value of the natural gas being used.
What is calor gas?
Natural gas - used for heating, cooking etc.
How much cheaper is natural gas heating than oil heating?
== == It depends on where you live and the cost of the fuel. You have to convert to the heating value of gas and oil, factor in efficiency, and then compare the cost per BTU's. For example: Determine the cost of gas vs. oil in your area: For example, heating oil in Seattle is $4.10 per gallon while gas is $1.09 per therm. Next, calculate the cost of fuel per MMBTU's. Knowing that heating oil has 138,690 BTU per gallon and natural gas has 100,000 BTU per therm, you can calculate using this equation: $ cost --------- X 1,000,000 = cost per MMBTU BTU's The result of the above step is $29.56/MMBTU for oil, and $10.87/MMBTU for gas. Next, divide the above by the efficiency of the furnace. Oil furnaces are 80 to 90% efficient and gas furnaces are typically 83% efficient. The net cost of the fuel per MMBTU is $34.78 for oil and $13.09 for gas in this scenario. If your old house uses 63 MMBTU a heating season, that is a total of $2,200 for oil and $824 for gas for the whole heating season
Why is heating a home with natural gas usually the cheapest option compared to heating with electricity?
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.
What is the original source of energy for this heating system?
The original source of energy for this heating system is electricity or natural gas. Electric heating systems convert electrical energy into heat, while gas heating systems burn natural gas to produce heat.
Can you use natural gas?
Natural gas is used for many purposes, including cooking and home heating.
