Mar 04, 2020 · There are mainly two types of boiler – water tube boiler and fire tube boiler. In fire tube boiler, there are numbers of tubes through which hot gases are passed and water surrounds these tubes. Water tube boiler is reverse of the fire tube boiler. In water tube boiler the water is heated inside tubes and hot gasses surround these tubes.
Steam Boiler Types : Types Of Boiler based on Functions, Designs and Consumption Industrial Boiler, Steam Boiler Industrial boilers are closed vessels requiring a fuel source or electricity in order to heat water or producing steam regarding industrial heating and humidification applications.
There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler. It is a fuel-fired hot water heater.
Water tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam raising and steam generation process is much faster
Rite's horizontal inclined water-tube boiler is also one of the most versatile boiler designs ever: equally at home as a hot water boiler, a low pressure steam boiler, a high pressure steam boiler. Rite Boilers are also available in two knock down versions, as weatherproof boilers, and can fire on most fuels including #2 oil (diesel) and biogas.
The steam cools and condenses into water. The cooled water flows back to the boiler to be reheated. Steam boilers need a pressure relief valve and a low water cutoff. The majority of steam boilers have a manual valve to allow for adding water to the system when necessary. Keep an eye on the water level gauge to keep the water level at its
Sitong boiler product multiple types of coal fired boilers, steam boilers, hot water boilers, thermal oil boilers, and other large industry boilers in china.
Jan 15, 2019 · A boiler is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy.
Apr 12, 2020 · boiler basics and types of boilers, water tube boiler and fire tube boiler. what is a boiler and its types, smoke tube boiler and water tube boiler. advantages and disadvantages of it. wet back design, dry back design.
Steam Production When heat is added to water, its temperature rises at a rate of 0.56°C (1°F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0°C (32°F) and we
Water-tube boiler. In water tube boilers, possibly in number of configurations water tubes are arranged inside the furnace. Normally there is lower and upper water tubes connecting large drums with lower ones containing water and upper ones with steam and water. In other types like monotube boiler through succession of coils water is circulated
Jul 19, 2019 · It is a fire tube, horizontal, internally fired, and natural circulation boiler, stationary and low-pressure boiler. Since it is a low-pressure boiler steam production will be less. Due to the lower steam production, the efficiency of the boiler is also low compared to the water tube boiler. The Lancashire boiler is shown in the figure below.
Different types of coal fired steam boilers are supplied by us for power stations. 240 ton coal fired steam boiler for power station . Chain grate coal fired boiler for power stations. DHL series corner tube chain grate boiler designed by is mainly based on the introduced GEF technology and technical researches on the chain grate boiler
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.
A fire tube boiler passes the hot combustion gases through the tubes, which are surrounded by the water to be converted to steam. A water tube boiler passes the hot combustion gases around the tubes, which contain the water to be converted to steam. In either type of boiler, the steam passes into a steam drum and then into the steam lines.

Other Boiler Types. Whilst fire tube and water tube boilers are the most common types, especially where high steam capacity is required, other designs do exist. i) Coil Boiler. The basic design is for feedwater to be pumped to single or multiple coils arranged around a burner.
The Stirling boiler is one type of water tube boiler, used for generating steam (50,000 kg steam/hour and 60 kgf /cm2 pressure) in the large area of the stationary plant. This type of boiler consists of 3 steam drums as well as 2 mud drums.
Carryover of impurities from boiler water to steam is also inherent to boiler operation. Though separation devices in drum boilers remove most water droplets carried by steam, some residual droplets containing small amounts of dissolved solids always carry through with the steam. Also, at higher pressures, there is some vaporous carryover.
Advantage and disadvantage of water tube boiler over fire tube boilers: Advantage: steam can be raised more quickly. steam at higher pressure can be produced. higher rate of evaporation. Sediment deposition is less. Suitable for any types of fuel and method of firing, More effective heat transfer.
2. Boilers Bureau of Energy Efficiency 29 2.3 Boiler Types and Classifications There are virtually infinite numbers of boiler designs but generally they fit into one of two cat-egories: Fire tubeor "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to
The boiler is a closed pressure vessel used to produce high pressure or low-pressure steam or to produce hot water fo r industrial or domestic use. Industrial steam boilers are classified in too many ways. Boiler Types According to tubing methods Ther e are two main types of boiler Fire tube boilers and water tube boilers.
May 27, 2019 · What is Boiler:-A boiler is outlined as "A closed vessel during which water or different liquid is heated, steam or vapor is generated, steam is super heated, or any combination therefrom, besieged or vacuum, to be used external to itself, by the direct application of energy from the combustion of fuels, from electricity or energy ".
Mar 04, 2020 · This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water. Advantages of Water Tube Boiler. There are many advantages of water tube boiler due to which these types of boiler are essentially used in large thermal power station.
Nov 02, 2017 · This video describes the complete demonstration that how coal fired boiler actually works by an animated video.
Corner tube boiler: a natural circulation water tube boiler in which the pre-separation of steam takes place from the water-steam mixture outside the drum and the preheated downcomers. Cornish boiler : a large horizontal stationary boiler with a single flue.
Water tube boiler parts and their functions. There are many pressure parts and non pressure parts in a water tube boiler we only discuss main water tube boiler parts and function. Steam drum. Steam drum is a collection vessel for steam & water. Here water & steam is separated. It has steam separators.
These types of boilers are ideal in operations where there is a large and constant steam demand. However, they are typically not suitable for high pressure applications. Water-Tube Conversely, in a water tube boiler the water is inside the tubes and the heat source is on the outside. This ability for rapid heat transfer makes water-tube setups
