regenerative furnace

An open-hearth furnace using producer gas as a fuel, but so arranged that the gas is conducted to the hearth area through a passage-way filled with red-hot bricks stacked to form an open checkerwork. As the hot gas enters the furnace, it is mingled, in proper proportions, with air similarly heated; so that complete combustion is produced. The escaping hot gases are conducted through a second passage-way filled with bricks, which absorb much of the waste heat. The two passage-ways are used alternately to heat the producer gas as it is fed into the furnace. (Bridge, 2019)
