Solution
The correct options are
A Cheap fuel
B Non-polluting fuel
C Convenient fuel
D All of these
Cyclone dust collectors use centrifugal force to remove large and high-volumes of dust from industrial applications. Electrostatic Precipitator is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge. Modern automobiles are equipped with a device called catalytic converter that reduces emissions of three harmful compounds found in car exhaust: carbon monoxide (a poisonous gas), nitrogen oxides (a cause of smog and acid rain) and hydrocarbons (a cause of smog). Tall chimneys in factories help to reduce air pollution at lower levels.
