Solid fuel fired hot water boiler is single drum water tube and fire tube boiler, combustion equipment is chain grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area.
In fire-tube boilers, the flue gas passes inside boiler tubes, and heat is transferred to water on the shell side. A dynamic model has been developed for the analysis of boiler performance, and Matlab has been applied for integrating it.
Importance of fire-tube boiler water treatment is also caused by some design features: primarily by the high density of heat fluxes through the fire-tube surfaces. In modern fire-tube boilers value of this parameter is about three times higher than the water-tube boilers heat fluxes.

The ASME symbol will identify the boiler or accessory type. On a fire tube boiler, it may be located on the right side near the front, by the water column. On a water tube boiler, it will be located next to the manhole on the steam drum.
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.
The boiler consists fundamentally of the combustion and heating chambers and other parts such as: fire tubes, water container, steam trap, steam tap, exhaust pipe and boiler casing which are designed in the geometry of the laboratory fire-tube steam boiler.
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).
The boiler consists of a shell, a tube sheet on each end of the shell, and tubes connecting the two tube sheets. The boiler is mounted above a steel or masonry furnace. The products of combustion leave the furnace and are directed through the tubes at one end of the boiler.

A fire-tube boiler is composed of a gas-box with tubes containing boiling water. When the boiler was new the overall heat-transfer coefficient was found to be 400W/m^2-K. After a few years in service, carbon deposits on the outside (gas-side) of the tubes and scale deposits on the inside (water side) have formed reducing the overall heat
Nov 19, 2013 · A fire-tube boiler’s main components include a cylindrical shell, a series of tubes, a feedwater inlet line, and a combustion gas outlet stack. The name “fire tube” is very descriptive. The fire, or hot flue gases from the burner, is channeled through a group of steel tubes that are surrounded by a shell filled with water.
applications. Fire tube boilers can take a great deal of abuse and inattention and still function at competent levels. Fire tube boilers have a life expectancy of 25 years or more. Boilers that are older than 75 years are still known to be in operation. Consistent maintenance and careful water treatment go a long way towards insuring the long life of these boilers.
Fire Tube Boiler. The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes. Mostly used boiler in small and medium industries with different fuels and steam pressure requirements.
Smoke tube boiler and water tube boiler are the main types of industrial boiler in global market. They are differ from not only structure, but also usage. Smoke tube boiler. Smoke tube boiler, as its name suggests, of which smoke or heat flowing through boiler tubes and the water surrounds outside of the tubes to be heated and turned into steam.
Mar 19, 2016 · One is known as fire tube boiler and the other one is known as water tube boiler. These boilers is largely used in power development and other industrial like sugar industries, cotton industries etc. for steam generation. The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water
