LP gas is considered more hazardous than natural gas because? LP tends to puddle in low areas but natural gas tends to dissipate. Which of the following is a product of complete combustion?
Which of the following is a product of complete combustion?
During complete combustion carbon and hydrogen combine with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O).
What are the products of incomplete combustion of a hydrocarbon gas?
Incomplete combustion happens when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced.
What are the products of complete combustion of a hydrocarbon gas?
Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat.
What can be done to minimize the pollutants produced by a gas furnace?
What can be done to minimize the pollutants produced by a gas furnace? To prevent air pollution, air intakes, filters, ducts, and system components. And very importantly seal leaks.
What are two products of a combustion reaction?
Most combustion reactions produce carbon dioxide and water, so these chemicals are written as the products on the right of the equation. Charcoal is a fuel that contains carbon atoms but no hydrogen atoms.
What are the 4 possible products of an incomplete combustion?
- Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide.
- In general for incomplete combustion:
- hydrocarbon + oxygen → carbon monoxide + carbon + water.
- propane + oxygen → carbon + water.
What are the basic elements of common fuel gases?
Fuel gases consist of combustible compounds like hydrocarbons, hydrogen (H2), and carbon monoxide (CO), which are the source of energy, and of incombustible compounds like helium (He), nitrogen (N2), and carbon dioxide (CO2), which decrease the specific energy content.
Why does natural gas require the least amount of excess air?
Natural gas requires much less air in combustion because of its relatively low amounts of carbon and high amounts of hydrogen. … In addition to the carbon dioxide emissions, gas burning creates NOx emissions, while the emissions of sulfur dioxide (SO2) and Particles are negligible.
How much air is required for combustion of natural gas?
For natural gas-fired burners, the stoichiometric air required is 9.4-11 ft.3 / 1.0 ft. of natural gas or approximately an air-to-gas ratio of approximately 10:1. In this case, there is an excess oxygen level of 2%. In the combustion zone, it is challenging to measure excess air.
