• sub-bituminous

Find out the incorrect statement?

• The handling of liquid fuels is easier and they require less storage space.

• The combustion of liquid fuels is nonuniform

• Liquid fuels pose problems in cold climates since the oil stored in the tanks is to be heated inorder to avoid the stoppage of oil flow.

• The firing of liquid fuels can be easily controlled. This permits to meet the variation in loaddemand easily
