Why is stoichiometric combustion rare?
Stoichiometric combustion is almost never possible because of imperfect fuel-air mixing. For economy and safety, most combustion equipment (such as heaters, furnaces, and engines) should operate with excess air to ensure that fuel is not wasted and that combustion is complete
Methanol stoichiometric ratio?
The stoichiometric ratio for methanol is 1:1. This means that one mole of methanol reacts with one mole of an oxidizer, such as oxygen, in a complete combustion reaction. This ratio is essential to calculate the amount of reactants needed to ensure complete conversion of methanol to products.
Can a blue flame produce CO?
Yes, a blue flame can produce carbon monoxide (CO) if there is incomplete combustion of a carbon-containing fuel. Blue flames result from complete combustion, but if the fuel-to-air ratio is not ideal, leading to incomplete combustion, CO can be formed.
What is the constant ratio of carbon monoxide to oxygen in a balanced combustion reaction?
The constant ratio of carbon monoxide to oxygen in a balanced combustion reaction is 1:1.
Best Hydrogen gas to Oxygen gas ratio for combustion to occur?
The reaction is 2H2 + O2-> 2H2O So, both the molar and volume ratios would be 2 moles(liters) of hydrogen to every mole(liter) of oxygen. By weight, the ratio would be about 8 grams of oxygen to every gram of hydrogen
What is the definition of combustion efficiency?
The ratio of optimum energy derived from the minimum use of fuel energy during combustion.
Define complete combustion and write a chemical equation for the complete combustion of methane gas?
Complete combustion is the reaction with oxygen of a material containing at least one of carbon and hydrogen to convert all of the carbon content of the material to carbon dioxide and all of the hydrogen content to water. For methane, CH4 + 2 O2 = CO2 + 2 H2O. But minimum speed range for the CNG vehicle in driving condition should be atleast 50 km per hour for optimum oxygen ratio with methane to achieve complete combustion of CNG

Compression ratio of the internal combustion engine is defined as?
The compression ratio of an internal-combustion engine, or an IC engine as it is more commonly called, is the ratio of the volume the highest capacity of the combustion chamber to its lowest capacity. In the IC engine, the piston makes a stroke, resulting in the compression of the air in the combustion chamber - the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke, is the compression ratio.
What does AFR 14k mean?
AFR 14k refers to an air-fuel ratio (AFR) of 14 parts air to 1 part fuel by weight, which is considered the ideal stoichiometric ratio for gasoline combustion in internal combustion engines. This ratio ensures complete combustion, maximizing efficiency and minimizing emissions. Deviations from this ratio can lead to rich (too much fuel) or lean (too much air) conditions, impacting performance and engine health.
What does a combustion controller maintain?
A combustion controller maintains the optimal air-fuel ratio in a combustion process to ensure efficient and safe operation of the system. It regulates the amount of fuel and air supplied to the combustion chamber to achieve complete combustion and desired results.
Can a blue flame produce CO?
Yes, a blue flame can produce carbon monoxide (CO) if there is incomplete combustion of a carbon-containing fuel. Blue flames result from complete combustion, but if the fuel-to-air ratio is not ideal, leading to incomplete combustion, CO can be formed.
What is the constant ratio of carbon monoxide to oxygen in a balanced combustion reaction?
The constant ratio of carbon monoxide to oxygen in a balanced combustion reaction is 1:1.
How can we reduce the combustion of fossil fuels?
You can change the air-to-fuel ratio to get less optimal combustion.
What is cutoff ratio?
Cutoff ratio is not the ratio of the volume of the cylinder at the end of combustion to the start of the combustion process in a diesel engine. actually cutoff ratio means point at which fuel injected for a period and fuel delivery is stopped at required instant -is called cutoff ratio.............
