In general, condensing boilers are identified by their internal construction as either fire-tube or water-tube boiler designs, as illustrated in Fig. 2 below. A fire-tube, as the name suggests, has the hot flue gases from the combustion chamber, passing through the tubes and out the boiler vent. These tubes are surrounded by a water jacket.
A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.

Answer (1 of 10): A firetube boiler is a boiler that combusts the fuel in a chamber and then passes the hot exhaust gasses through a series of tubes with water on the outside of them. They generally operate at less than 300 psi and produce steam with moderate steam quality (dryness). They general
The Advantages of Fire Tube Boilers: Compact in construction. Fluctuation of steam demand can be met easily. Cheaper than water tube boiler. Disadvantages of Fire Tube Boilers: The time required for steam pressure to rise can be quite long. Steam output pressure cannot be very high since the water and steam are kept in the same vessel.
The general outline of the fire-tube boiler is that it consists of two or more horizontal cylinder furnaces, located at the base of the boiler shell. The burst gases and smoke pass from the furnace to the back of the boiler and return to its small tubes and get worn out of the chimney.
Fire tube boilers are the third of the four historical types of boilers: low-pressure tank or "haystack" boilers, flue boilers with one or two large flues, fire tube boilers and high-pressure boilers with many small tubes. Water Tube Boiler. Water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire.
