A type of boiler used to generate steam power, fueled by burning wood. In the 19th century, before coal became widely available in Great Lakes ports, wood was the primary fuel source for steamboat boilers.
Usage in the Canadian:
The Canadian used a down-return flue boiler, built by John Dunham of Detroit, that was 11 feet in diameter and 30 feet long. The wood-fired boiler was economical and efficient for the time, capable of running the vessel 150 miles on 10 cords of hardwood while producing 35 pounds of steam pressure.
