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

Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to …
The following are specified limit for high pressure boiler from different organization:- ASME Guidelines for Water Quality in Modern Industrial Water Tube Boilers for Reliable Continuous Operation:-Boiler Feed Water Boiler Water Drum Pressure (psi) Iron (ppm Fe) Copper (ppm Cu) Total Hardness (ppm CaCO3) Silica (ppm SiO 2) Total Alkalinity**
pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.
Boiler steel pipes includes medium pressure boiler pipe and high pressure boiler pipe, it is often manufactured in seamless procedures, welded steel pipe is not applicable. It has been widely used at heat exchanger pipe and tubing services, tube exchanger bundle, high pressure boiler, economizer, super heater, petrochemical industry pipes, etc.
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. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica
Apr 27, 2015· 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…
The water tube boilers are mainly used for generating steam with high temperature as well as pressure. The internal structure of this boiler includes a tiny steam drum, small width tubes. The components of this boiler generate high-volume vapor for high-capacity applications. These boilers are most frequently used boilers, which has replaced
· Web viewSECTION 23 52 33. WATER TUBE BOILERS. SPEC WRITER NOTES: shall form a part of this specification. With burner at high fire, the boiler pressure shall not rise more than 6 percent above the set pressure of the safety valve with the highest pressure setting and no more than 6 percent above the maximum allowable working pressure of the boiler.
