This question was addressed to me in class test.

Asked question is from Gaseous Fuels topic in portion Fuels and Combustion of Engineering Chemistry II

Answer 1

Right option is (a) Gaseous coal does not form ash

For explanation: Ash content is present in the fuel itself. Due to the presence of ash content in solid and liquid fuels, its rate of combustion decreases. Also, a lot of smoke is generated due to the presence of ash content.
