A boiler is an enclosed vessel in which water is heated and circulated, either as hot water or steam, to produce a source for either heat or power. A central heating plant may have one or more boilers that use gas, oil, or coal as fuel. The steam generated is used to heat buildings, provide hot water, and provide steam for cleaning, sterilizing,
• Water-tube boilers have water running through the tubes and fire or gases of combustion surrounding the tubes. The water tubes are connected into a steam drum at the top and a mud drum at the bottom.
Aug 22, 2018 · A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded b
The firetube boiler design (see Figures 1-1 & 1-2) uses tubes to direct the hot gases from the combustion process through the boiler to a safe point of discharge. The tubes are submerged in the boiler water and transfer the heat from the hot gases into the water. inside a firetube boiler the hot gases travel down the furnace

Water tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam raising and steam generation process is much faster
Apr 17, 2015 · Fire Tube Boilers 8. Water Tube Boilers In this type of boiler water passes through the tubes while the gases remain in the shell side, passing over the tube surfaces • Used for high steam demand and pressure requirements • Capacity range of 4,000 – 120,000 kg/hour • Combustion efficiency enhanced by induced draft fans.
Fire Tube Boilers Also referred to as smoke tube boilers, shell boilers, package boilers Multiple gas paths - 2, 3 and 4 pass Internal furnace or fire box as the 1st pass Dry back or wet back design Single fuel or dual fuel design Little or no steam separation equipment
D type watertube boiler design. D type watertube boilers are designed with a large steam drum at the top, vertically connected to a smaller water drum (or "mud drum") at the bottom, via multiple steam-generating tubes which carry feed water (providing the main heat transfer surfaces for the production of steam).

Water tube boilers are used for high-pressure boilers. Fuel is burned inside the furnace, creating hot gas which heats up water in the steam generating tubes. Types of water tube boiler Babcock Wilcox boiler, Sterling boiler etc. Fig. Schematic Diagram of a Water Tube Boiler. 12 Water Tube Boiler Babcock Wilcox boiler. 13
Nov 19, 2013 · A water-tube design is the exact opposite of a fire tube. Here, the water is inside the tubes and the combustion gases pass around the outside of the tubes. Water-tube boilers may vary in design; however, their basic principles of operation are the same. This type of boiler consists of two drums, a series of water tubes, a feedwater inlet line
an overview of the various types of boilers. In a firetube boiler, water surrounds the furnace and tubes that house the flame and hot gases. Firetube boilers normally range in size from 15 to 2,200 horsepower as a package with design pressures between 15 and 250 pounds for steam and between 30 and 160 pounds for hot water.
