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
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
Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy
Furnaces consist of boilers, soot blowers to transfer the mixture of steam-water to furnace, burners and combustion air systems, a pressure system for emission of flue gases, and pressurized air system for sealing the system to avoid flue gas emission. The boiler tubes are placed between steam distribution drums and water collectors at the

water tubes and cause tube failure. Re-tubing of the boilers is a very expensive upgrade and thus it makes feed water treatment an essential step in boiler operation. Phosphates, chelates, and polymers are commonly used for water treatment in boiler plant. By properly treating the water the life of the boiler tubes will be extended.

Firebox boilers 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
Benson Boiler is a high pressure, drum less, supercritical, water tube steam boiler with forced circulation. This boiler was invented in the year 1922 by Mark Benson. This boiler is a super critical boiler in which the feed water is compressed to a supercritical pressure and this prevents the formation of bubbles in the water tube surface.
Water-level control and low-water fuel cutoff. Many systems combine these two separate boiler-safety functions into one unit. They are designed to ensure the water level within a boiler never falls below a predetermined amount. Should that situation occur, the system is designed to shut down the boiler by cutting off its fuel.
treated boiler water and the tube materials. As the oxide-scale on the tube wall increases, it acts as a thermal barrier and an effective insulator causes slow heat transfer from the hot flue
Superheater—tubes located near the boiler outlet that increase (superheat) the temperature of the steam, p. 297. Waste heat boiler—a device that uses waste heat from a process to produce steam, p. 297. Water tube boiler—a type of boiler that contains water-filled tubes that allow water to circulate through a heated firebox, p. 296.
large water tube boilers and some fire tube boilers. In order for an individual to gain access to a boiler through a manhole, there must be a confined space entry permit procedure in place for proper and safe entry. New gaskets should always be used after inspection so that boiler openings will seal properly when placing the boiler back into

Water treatment program for boiler systems Water treatment = preventative maintenance program to minimize corrosion and scale in the boiler and carry over/deposits on the turbine. Well designed water treatment program can significantly reduce your energy, water, and maintenance costs while ensuring safe and reliable operation. Small reductions in boiler or condenser efficiency - huge increases

Due to the flexible water tube design, floor space require-ments are minimized, while heating surface area per boiler HP is exceptionally high. The CL Series requires only 24" clearance for servicing the water tubes, only on one side of the boiler. Dramatically reduced space requirements in a boiler room mean considerable savings in building costs.
Another problem associated with water chemistry and water-side deposits is the corro- sion of the tube. A common corrosion problem is the pitting of tubes due to the ingress of oxygen into the boiler water. The oxygen tends to attack welds and backing rings preferen- tially and can lead to eventual failure. In addition there are two major types
FIRE TUBE refers to a boiler with straight tubes, which are sur-rounded by water and steam and through which the products of combustion pass. BOILER RATINGS Packaged boilers are rated on the basis of maximum continuous nozzle output, in terms of boiler horsepower, B.T.U. per hour, or pounds of steam per hour at 212° F. Available information can be

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

How Water Tube Type Steam Boilers Work. One of the latest advances in steam boiler technology is the use of water tube boilers.This type of boiler is distinct from conventional fire tube boilers. Water tube boilers are more efficient than fire tube boilers, generating more steam but using less fuel. They are also much safer than fire tube boilers and easier to manage when it comes to routine
