Water Tube Boiler For Sale
Water tube boiler, also known as water-tube system, is a type of boiler used to generate steam, generally in large industrial or utility plants. They are most commonly found in large power generation facilities and often have multiple vessels connected to the same central furnace.
What is the name of water tube boiler?
D type water tube boiler
The name water tube boiler can be confusing because the term is also used to refer to other types of boilers. A water tube boiler is essentially a series of tubes that contain water, which are surrounded by another set of tubes containing pressurized steam. This design allows for efficient heat transfer from the firebox to the top of the boiler and then through to its tubes, which in turn helps create steam pressure as needed.
The name fire tube boiler has been largely replaced by “water-tube furnace” or “fire-tube furnace” in modern usage—but these terms still have their origins in early designs employing open fires directly under boilers. These early designs required large amounts of air flow for combustion purposes; this led to cooling problems when combined with water-filled tanks located directly below them (especially during cold weather).
In order for these systems not only function properly but also be safe enough for use indoors (where they could be properly insulated), designers started using cylindrical chambers instead – creating something not unlike what we now think about when describing a standard water-tube design!
How does a water tube boiler work?
How a water tube boiler works
A water tube boiler is a steam boiler that uses water tubes, instead of fire tubes, to heat the water. They have a higher thermal efficiency than fire-tube boilers and can operate at higher steam pressures, but are more vulnerable to corrosion. The first water-tube boiler was patented in 1866 by Hermann von Meyer and was used in many industrial applications quickly thereafter. The first use of the term “water tube” was applied to this type of boiler around 1875 by James Sprunt III when he coined it as part of his company name: Sprunt’s Water Tube Boiler Works (now known as Sprunt Plumbing Products).
Water tube boilers were used for high pressure engines such as those used on railroads. Although this design has been abandoned for these applications, it remains popular for stationary power generation due to its high efficiency and ease of operation with automatic controls (and thus low operator skill requirements) when compared with traditional designs such as drum type boilers or coal fired simple flues.
What is the main feature of a water tube boiler?
Water tube boiler advantages
The main feature of a water tube boiler is its high efficiency. It also has many other advantages that make it the most preferred choice for manufacturing industries. It can produce steam at pressures as high as 20 MPa, temperatures up to 700°C and a variety of media including fossil fuels like oil or gas, biomass, etc.
The design of a water tube boiler allows it to withstand high pressure and temperature conditions while providing efficient heat transfer from reaction to water. Water tubes are usually made from carbon steel plates with thickness about 10mm thick; however, some manufacturers use stainless steel tubes for corrosion resistance purposes or even titanium tubes for higher pressure applications where corrosion resistance is important but cost is not an issue (such as in military-grade aerospace engines).
Where is water tube boiler used?
Industrial water tube boiler
Water tube boilers are used in a wide range of industries, including power plants, industrial plants and chemical industry. This type of boiler is used for the following applications:
- Boiler-turbine units in thermal power stations.
- Boiler-steam generators in nuclear power stations.
- Heat exchangers in oil refineries and petrochemical plants.
What is advantage of water-tube boiler?
Advantages of water tube boiler
Water-tube boilers are high efficiency and reliable because of their compact size, light weight and good heat transfer.
Water tube boiler has the following advantages:
- High efficiency (45% – 60%)
- Good reliability and low maintenance cost
- Low emissions (NOx)
- High safety due to its simple design with only one moving part
Water tube boilers produce more steam than fire-tube boilers of equal size. The higher steam production can be attributed to the use of water tubes in which there is better contact between the steam and the radiant heating surfaces than in firetube boilers.
How much is the efficiency of a water tube boilers?
Water tube boiler efficiency
The efficiency of a water tube boiler is between 70% and 85%. This means that for every unit of fuel burned, the water tube boiler produces 70%-85% of the potential energy.
The efficiency of a fire tube boiler is between 60% and 75%. So why is it that the efficiency of a water tube boiler is higher than that of a fire tube boiler? The answer lies in how they are constructed.
The tubes used in both boilers are made from copper or steel, but the difference lies in what kind of insulation they use between each tube. In a fire-tube type boiler (such as an oil-fired furnace), each individual pipe has its own layer of insulation around it—this works well when trying to keep heat contained within these pipes because there’s no way for hot gases to leak out onto other parts further away that would normally be colder than where they started out;
however, since there’s less metal involved here compared with when we talk about water tubes (which have their own metal frame surrounding them), this means there isn’t enough material available for insulation purposes so not all those fumes get trapped inside where they belong! Instead some escape into surrounding areas where temperatures might be lower yet still high enough so as not to cause damage if left unchecked over time.”
Water tube boilers are a type of boiler that uses water tubes to transfer heat to the water in order to produce steam. They are very efficient and used in many industries including power plants, chemical production facilities and oil refineries because of their ability to handle large amounts of heat without overheating or burning out like other types of boilers would do.
Water tube boilers are also much safer than other types because they don’t use any fuel oil or natural gas so there is no chance for an explosion like there would be if someone tried start up a coal-fired boiler room without properly monitoring everything first!
