Jul 02, 2019 · A high-pressure boiler is defined as a boiler in which steam or vapor is generated at a pressure equal to or greater than 15 psig, or a boiler in which water is heated at a temperature of 250°F and a pressure greater than 160 psig, when water is heated for use external to the boiler itself.
Watertube boilers are the boiler of choice for industrial process applications and are used much less frequently for building heating purposes. The main advantage of watertube boilers is their increased capacity, including the ability to handle greater pressures up to 5,000 psig and very high temperatures, which offers superior steam generation—in the millions of pounds/hr.

How Water Tube Type Steam Boilers Work. One of the latest advances in steam production 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.
Dec 02, 2016 · Fire tube boilers are designed to transfer hot gases from the heating source and cycle these gases through tubes that circulate through a drum filled with water. This process effectively transfers the heat from the gas into the water, which effectively generates steam.
C. Boiler Water Level: On every steam boiler there is a small glass tube located on the outside of the boiler. Commonly called a "Gauge Glass", this tube indicates the precise level of the water in the boiler.

One of the latest advances in steam production 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.
Two types of boilers are most common—fire-tube boilers, containing long steel tubes through which the hot gases from the furnace pass and around which the water to be changed to steam circulates, and water-tube boilers, in which the conditions are reversed. Water is changed to steam in these continuous circuits and also is super-heated in transit.
Retubing & tube replacement for boilers of all sizes. IB&M specializes in the retubing of firetube boilers, watertube boilers, superheaters, pre-heaters, heat exchangers and other pressure vessels. Boiler tubes must be able to endure extremely high temperatures, pressures, and potentially wide fluctuations in demand depending on the application.

Alternative water-tube boiler layouts. The following layouts work on the same principles as other water-tube boilers, and are available with capacities from 5 000 kg/h to 180 000 kg/h. Longitudinal drum boiler. The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5).
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.
Water-tube boilers feed water (rather than combustion gases) through tubes. A large number of these tubes run through a boiler drum (casing) where heated gases or heating elements surrounding the tube bring the water to its boiling point.
In a water-tube boiler (" 'Figure 3" '), the water is inside the tubes and combustion gases pass around the outside of the tubes. The advantages of a water-tube boiler are a lower unit weight-per-pound of steam generated, less time required to raise steam pressure , a greater flexibility for responding to load changes, and a greater ability to operate at high rates of steam generation.
Tubes are the heart of any boiler unit. Improper deaeration and water treatment can significantly affect the lifespan of tubes. Additionally, tube replacement can often indicate water quality issues that need to be addressed. Retubing can increase the life of the unit by many years.
The boiler consists of a shell, a tube sheet on each end of the shell, and tubes connecting the two tube sheets. The boiler is mounted above a steel or masonry furnace. The products of combustion leave the furnace and are directed through the tubes at one end of the boiler.
May 01, 2011 · A boiler is a box formed by tubes that uses fire inside that box to heat water into steam. Surrounding those tubes and completely encasing the tube walls and the firebox area are the bril (brick, refractory, insulation, and lagging) materials.
A water-tube boiler is a type of boiler in which water circulates in tubes heated by fire from outside. The fire is produced by the fuel being burned inside the furnace for the boiler.
