List of tallest chimneys in the world

A list of the tallest chimneys of the world.

Although many kinds of industrial facilities have tall chimneys most of the chimneys with heights of 200 metres and more are part of thermal, especially coal-fired power stations. Only few smelters, steel mills, chemical factories and oil refineries use such tall chimneys.

Since the beginning of the industrial revolution, tall chimneys were built, at the beginning with bricks, and later also of concrete or steel. Although chimneys never held the absolute height record, they are among the tallest free-standing architectural structures and often hold national records (as tallest free-standing or as overall tallest structure of a country).

Hamon Custodis claims to have built a 707-foot 215.5 meter stack in 1953 but there are no references to the location or client of this/these stack(s). Skyscraperpage indicates the 846 ft 258 m Chimney of Omskaya Cogeneration Plant #4 was built in 1965 but it's likely that this date is referring to the construction of the first section of the plant with the smaller chimney. No other references or information can be found to corroborate this claim.
