In flue curing, also known as the Virginian cure, fires are set outside the barn; and the heat led in iron pipes or flues, into the building are under the suspended tobacco, which is placed there quite fresh from the field.
In many mints the flues pass into condensing chambers where volatilized gold and silver are recovered.
[M] church has on its east side the "pisalis" or "calefactory" (H), the common sitting-room of the brethren, warmed by flues beneath the floor.
Beyond this we often find the calefactorium or day-room - an apartment warmed by flues beneath the pavement, where the brethren, half frozen during the night offices, betook themselves after the conclusion of lauds, to gain a little warmth, grease their sandals and get themselves ready for the work of the day.
Plant houses were formerly heated in a variety of ways - by fermenting organic matter, such as dung, by smoke flues, by steam and by hot water circulating in iron pipes.
