Low and medium pressure boilers must be protected from scale deposition and corrosion to promote optimum energy efficiency and prolong the useful life of the plant equipment. The definition of low and medium pressure is somewhat discretionary. For the purposes of this discussion, low pressure shall apply to boilers up to 150 psig. These boilers
Whatever the type of fuel being fired, all high pressure boilers are bound to have a tube failure during the course of their working life. Did you know that a single tube failure in a 500 MW boiler requiring four days of repair work can result in a loss of more than $1,000,000 apart from the generation loss?

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.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes
The HP boiler worked at approx 850 psi (5.86 MPa), and the low-pressure boiler at 200 to 250 psi (1.38 to 1.72 MPa). The UHP and HP boilers were of a water tube design, while the LP boiler was a fire tube boiler typical for steam locomotives. The LP cylinders were driven with a mixture of the HP cylinder exhaust and the LP boiler output.
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.

3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar. 4.Flex tube boilers: a)Primarily for non-critical service firing gas fuel and with stable steam demands.
Special features of water tube boiler: Water tube boilers have the high evaporating capacity (20,000 to 40,000 kg/h) compared with other boilers. The operating pressure lies between 11.5 to 17.5 bar. The draft losses are minimum. The defective tubes in water tube boilers can be identified and replaced easily.

The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.
This boiler is chosen if the steam demand and steam pressure are very high as in the case of a boiler for power plants. A very modern water tube boiler designed with a steam capacity between 4,500-12,000 kg / hour, with very high pressure. Working of water tube boiler. The ignition process occurs outside the pipe. The heat produced is used to
stable in boiler water. Rather, like many boiler chemi- cals, it has a limited stability that does not preclude its use in boilers. In field studies feeding H EDP or PBTC, there has always been a residual found, even when being applied at 800 psig and at 20 cycles of concentration. Temperature and corresponding pressure affect stability;
A complete line of Indeck Volcano "A" style package boilers are offered to provide the ability to fire the dirtier fuels while still incorporating the benefits offered with a package designed steam generator.

pressure boilers, pressurized ﬂuidized bed boilers, gas turbine-combined power generation boilers, and high-efﬁciency industrial waste incineration boilers have been constructed one after another, as new ther-mal power generation boilers. Steel tubes and pipes, to be used to respond to these situations, have been
Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers.

BOILER AND PRESSURE VESSEL INSPECTION (R.I.G.L. - 28-25) High Pressure, High-Temperature Boiler - A boiler in which water, oil, or other fluid is heated and at a pressure not exceeding l5 psi steam pressure or a hot water boiler in which water or other fluid is heated and intended for operation at pressures not exceeding l60 psi or
systems. Chemical treatment of hot water heating boilers is discussed in this section and also in chapter 4 (cooling water). This chapter is organized by chemical treatment (oxygen scavengers, internal treatments, condensate treatment, etc.). Then the treatments are classified by application to boilers in the pressure groupings above.
Why Water Tube Boilers ? In contrast to its internal construction, which includes a small steam drum and small diameter tubes, the water tube boiler is used to generate steam having high pressure and temperature. These small internal parts produce high volume steam for high capacity applications.

The Columbia Multi-Pass Horizontal (MPH) boiler is a modified scotch boiler designed for hot water, and/or low pressure steam applications. The pressure vessel is available as a welded pipe boiler or a rolled tube boile r. These units are manufac - tured to the specifications set forth by Section IV of the ASME Boiler and Pressure Vessel Code.
Water-tube boiler - Wikipedia. 2019-5-16 · 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 system pressure must be at least 25 psig above the saturation pressure of the high-temperature water's maximum temperature to prevent pump cavitation and flashing of superheated water to steam. Section 1004 of the International Mechanical Code (IMC) describes the minimum allowable requirements for boilers.
The whole point is that the Babcock-Wilcox is a water tube boiler designed for large volumes of steam, while the Cochran one is a firetube one for small plants designed with a small foot print.
High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.
For more on Boiler Selection Firetube. Non-condensing firetube boilers are available for low- or high-pressure steam, or for hot water applications. Typically used for applications ranging from 15 to 2,200 horsepower, a firetube boiler uses a cylindrical vessel, with the flame in the furnace and the combustion gases inside the tubes.

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
Fire-tube boilers have the advantage of being easy to install and operate. They are widely used in small installations to heat buildings and to provide power for factory processes. Fire-tube boilers are also used in steam locomotives. In the watertube boiler, the water is inside tubes with the hot furnace gases circulating outside the tubes
