'Flue' is a word that refers to a pipe or tube that allows smoke, gas or air to escape from a building or a device like a stove or furnace. It is usually found inside a chimney or exhaust system. For instance, when you burn wood in a fireplace, the smoke goes up through the flue to vent outside. Similarly, in a gas water heater, the flue removes the harmful gases resulting from the combustion process. Knowing the word 'flue' can be useful when talking about home or industrial heating systems, ventilation, and air conditioning.
