The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.
The firebox boiler uses similar tube attachment techniques as the firetube boiler. Its combustion chamber is not round, like the firetube’s cylindrical furnace. The firebox boiler is typically manufactured to low pressure steam or hot water applications. The firebox boiler is a compact, economical unit and serves as a good fit for
Reasons for Increasing Exhaust Gas Temperature of Boiler
The heat loss of exhaust gas is the biggest one of all the heat losses of boiler. Generally the loss heat is 6% of the heat input into the boiler furnace. The heat loss of exhaust gas increases by 0.5% when the temperature of exhaust gas increases 12-15%.
Alternative water-tube boiler layouts. The following layouts work on the same principles as other water-tube boilers, and are available with capacities from 5 000 kg/h to 180 000 kg/h. Longitudinal drum boiler. The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5).
In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.
The structure of SZS series gas fired water tube boiler is arranged as drum longitudinal type “D” shape, it’s quickly assembled boiler with water tubes, has the characteristics of high steam quality, sufficient output, and high thermal efficiency (97%), etc.

Water-tube boiler: In this type, tubes filled with water are arranged inside a furnace in a number of possible configurations. Often the water tubes connect large drums, the lower ones containing water and the upper ones steam and water; in other cases, such as a mono-tube boiler, water is circulated by a pump through a succession of coils.
A water tube boiler is typically formed of four parts, a lower feed water drum – sometimes known as a mud drum – an upper steam drum with water surface from which the steam is evolved, water tubes connecting the two drums together and a super heater / economiser section (depending on the quality of steam required).
This type of boiler is known as an exhaust-gas boiler although it belongs to the Fire Tube boiler family as the exhaust gases are fed through tubes surrounded by water. For a variety of reasons only between 5-10% of the energy in the exhaust gases is recovered in the exhaust gas boiler and the working pressures are generally below 7 bar(g).
