Boilers are essentially shell-and-tube heat exchangers, with water being boiled to steam or transformed to high-pressure hot water. Heat is generated by burning a fossil fuel; the combustion gas can be ducted around tubes containing the water (water-tube boiler), or the hot gas can pass inside the tubes with the water being in the shell (fire
Parker Boiler made and still makes a water tube boiler (bent tube) that can be steam or hot water in sizes starting at 1.5 HP (50,215 BTU input). Lattner makes a vertical tube boiler starting at the same input as the Parker boiler. There have been others that are no longer in production that I saw in my 40+ years of boilers service.
22.214.171.124 Water-Tube Boilers . Most high-pressure and large boilers are of this type (Figure 9.2.2). It is important to note that the small tubes in the water-tube boiler can withstand high pressure better than the large vessels of a ire-tube boiler. In the water-tube boiler, gases low over water-illed tubes. These water-illed tubes

Water tube boilers: In water tube boilers, water and steam flow inside the tubes and the hot gases flow over the outside surface. Modern high capacity boilers are of water tube type. The boiler circulation system is constructed of tubes, headers, and drums joined in arrangement that provide water flow to generate steam.
Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
Parker Steam boilers have been designed to provide complete accessibility for internal inspection.

Fatigue accounts for 80% of the failures investigated in fire tube boilers and 28% in water tube boilers. Significantly in the non-sugar, watertube section this rises to 36% but drops to 17% for sugar boilers. However despite its low incidence in the sugar industry, it is worth a close look at the
The boiler is the heart of the steam system. The typical modern packaged boiler is powered by a burner which sends heat into the boiler tubes. The hot gases from the burner pass backwards and forwards up to 3 times through a series of tubes to gain the maximum transfer of heat through the tube surfaces to the surrounding boiler water.
Water tube boiler working and function 1. 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 2. Water tube boilers 3.
• (D) use a small orifice burner sprayer plate to start If choice D is selected set score to 1. 18. Which of the following is the best reason for opening the air cock when draining a water-tube boiler? o (A) Water flows out of the boiler too rapidly with the air cock closed. o (B) Air coming into the boiler will help dry out the boiler's
Residue that coats the tubes of a boiler will interfere with heat transfer and elevate the flue gas temperature. If incomplete combustion occurs, the resulting soot accumulates on the combustion side of the tubes. Similarly, poor water treatment practices can result in scale accumulation on the water side of the tubes.
Calculate the minimum required wall thickness of a water tube boiler 2.75 in O.D., strength welded (E, or, e = 0) into place in a boiler. The tube has an average wall temperature of 650°F. The Maximum Allowable Working Pressure (MAWP) is 580 psi gauge. Material is carbon steel SA-192. Note: Before starting calculations check the correct stress
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
Some of the most serious boiler operation problems, such as tube warpage, rupture, localized overheat, foaming, priming, and scale formation, can be traced to oil contamination of boiler feedwater.

The water-tube boiler is those boiler in which the water is present inside the tubes and fire or hot gases surround these fire tubes. The examples of water tube boilers are a La-Mont, Benson, Stirling, Babcock and Wilcox, Yarrow and Loeffler boiler.
The tubes are surrounded by water and the water is heated as the tubes also rise in temperature. Eventually steam is released for use. Water Tube Boilers - In contrast to fire tube boilers; a water tube boiler uses the water rather than the heat which is contained inside of a system of interconnected tubes.
