True or False: Excess air factor: The ratio of the theoretical amount of air required for fuel combustion to the actual amount of air supplied. （）
The excess air factor is the ratio of the mass of air actually supplied for burning 1 kg of fuel to the mass of air required for the complete combustion of 1 kg of fuel theoretically.
Excess air factor: The ratio of the theoretical amount of air required for fuel combustion to the actual amount of air supplied. (X)
Excess air factor: The ratio of the theoretical amount of air required for fuel combustion to the actual amount of air supplied. (Incorrect) It should be: the ratio of the actual mass of air supplied for burning 1 kg of fuel to the mass of air required for the complete theoretical combustion of 1 kg of fuel.
× Excess air factor: The ratio of the actual amount of air supplied during fuel combustion to the theoretical amount of air.
Error is the ratio of the actual amount of air supplied to the theoretical amount of air
Wrong. The excess air coefficient is the ratio of the mass of air actually supplied for burning 1 kg of fuel to the mass of air required for the complete combustion of 1 kg of fuel theoretically; it is an indicator used in countries such as China and Russia to study the composition of combustible mixtures, and is commonly denoted by the symbol λ.
Error, ---------it’s the opposite. The ratio of the actual mass of air supplied for burning 1 KG of fuel to the mass of air required for the theoretical combustion of 1 KG of that material
