Flued boiler - Wikipedia

The simplest form of flued boiler was Richard Trevithick's "high-pressure" Cornish boiler, first installed at Dolcoath mine in 1812. This is a long horizontal cylinder with a single large flue containing the fire. As the furnace relied on natural draught, a tall chimney was required at the far end of the flue to encourage a good supply of air (oxygen) to the fire.
