Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
choices — a 4 pass dry backed boiler or a 3 pass water backed boiler. This was a hard decision for many users. A 4 pass would have a higher efficiency, but higher maintenance costs associated with frequent refractory repair. While the 3 pass water backed required less maintenance, a decrease in efficiency could be expected.

Plant Theory Chapter 52 Firetube Boilers. Early fire tube boiler design Has an externally-fired brick furnace 2 Pass Boiler Less costly to build, Easy to clean, and has a relatively large water capacity Labour intensive to construct and inefficient to operate Although these boilers are no longer constructed, there are still some in operation. (Mostly in small industrial heating plants)
PACKAGED FIRETUBE BOILER Packaged firetube boilers represent the majority of firetube boilers being manufactured today. They are basically a two-pass, three-pass, or four-pass Scotch boiler, and can be either dryback or wetback in design. The boiler unit is engineered, built, tested, shop assembled, mounted on a steel
It has only one internal flue tube inside the boiler and diameter of the flue tube is 0.6 times the diameter of the cylindrical shell. Construction of Cornish Boiler: This boiler made with a long cylindrical external shell. This shell made by steel plates. You will find only one internal flue tube in this boiler.
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
Boiler Evolution 4 Steam Locomotive Cut-A-Way Furnace Convection tubes Steam dome Tube sheet Stack Water line NOTE: These boilers were an integral part in leading the way in the industrial revolution starting in the 1860’s.
A four-pass boiler design consists of four sets of horizontal tubes, with the stack outlet at the front of the vessel. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler. 4-pass boilers leverage natural draft operation which allows cool water to contact the hottest part of the boiler.

Water cooled, and furnace tubes are part of the boiler circulation circut. Coal, gas, and oil can be used as fuel, and gases are directed by baffles over tubes, making 3 passes from furnace to uptake.
There are two types of steam boilers. One is the fire tube, which is made from one combustion chamber and many tubes. The hot gases that are produced during the combustion process pass from inside the tubes and make a heat transfer with the water that is on the outside of the tubes. The other type is a water tube steam boiler.
