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.
Alarm on drum water level is required to control level of boiler water in the steam drum in which steam boilers are run with no continuous supervision that involves the vast majority of steam boilers especially for industries.
The boiler drum which is also known as steam drum is used on water tube boiler.The primary purpose is to separate the saturated steam from the steam-water mixture that leaves the heat transfer surface and enters the drum.The steam free water is recirculated within the boiler with the incoming feed-water for further steam generation.
The boiler tubes in the watertube design carry the heated water inside the tubes between the lower drum (mud drum) and upper drums (steam drum), with the generated steam accumulating in the upper drum.
The main components of a water tube boiler are the furnace, the tubes, the drums, the gas/oil burner, and the economizer. Cool water comes in through the inlet and then flows down the downcomer to then be heat in the pipes. As it heats the warmer water then begins to rise up the risers until it boils and becomes steam.
A steam drum (upper) and mud drum(s) (lower) are connected by the tubes, forming both the convection section and the furnace areas. Ranging in size from 500,000 to more than 20,000,000 BTU input, these boilers provide fast steaming capability because of the relatively low water content, allowing quick response to changing load demands.

For this reason, we can use the generated steam at the pressure from 40 kg to 140kg/cm. Flue GAS: In Water Tube Boiler flue GAS flows vertically.
Water-tube boiler - Wikipedia. A high pressure watertube boiler is a type of boiler in which water circulates. It consists of a large steam drum vertically connected to a smaller water drum (a.k.a. "mud drum") via multiple steam-generating tubes.
Boiler steam drum water level is one of the most important power plant parameters to both measure and control. Control of the proper water level in the boiler is critical for safe operation of the boiler. If the level is too low, boiler tubes will be damaged by overheating. If the
May 23, 2016 · Boiler steam drum acts as reservoir which provides necessary head for circulation of water through evaporation zone. Boiler steam drum has own feed water storage capacity it change according to the design of plant requirement. Steam drum supplied the water to boiler after that unit suddenly stopped or tripping of plant.
May 01, 2011 · The steam drum is 6.5 ft in diameter and collects and distributes the water/steam as it continuously circulates throughout the boiler. Once the water/steam enters the drum from the economizer outlet header via the economizer connecting pipe, it is forced by gravity down pipes called downcomers.
Oct 19, 2014 · THE BROTAN-DEFNER BOILER. The water-tube boiler was made larger so it was now a combined boiler and steam reservoir; ie just like a conventional locomotive boiler. It was this design that was used in over a thousand Hungarian locomotives. The sloping boiler section is a distinctive identification point.
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.
Aug 22, 2018 · These fire tubes or hot gas tubes heated up the water and convert the water into steam and the steam remains in same vessel. As the water and steam both are in same vessel a fire tube boiler cannot produce steam at very high pressure.
Boiler designers used four drums and three drums for designing water tube boilers during the initial days. Later as the boiler technology advanced in capacity and pressure, they switched over to bi-drum and single drum design. slide 1 of 2. High pressure boilers can be classified as single drum and bi-drum boilers.
Often the water tubes connect large drums, the lower ones containing water and the upper ones steam and water; in other cases, such as a mono-tube boiler, water is circulated by a pump through a succession of coils. This type generally gives high steam production rates, but less storage capacity than the above.
Boilers must be shut down several days prior to cleaning to allow cooling. Fireboxes of water-tube boilers should be cooled to essentially ambient temperature prior to entry. They must be left open to the room with the draft open to assure adequate ventilation before entry. B. Lockout/Tagout. In accordance with
4.10.3 Water. The boiler water concentration in the steam drum should be specified in the job specification. Samples of water for testing should be taken from the continuous blowdown. Samples should be taken through a cooling coil to prevent flashing.

A steam boiler is an enclosed container where water is heated under controlled conditions to convert it into steam. Boiler is basically a heat Unilux Steam Boilers, Hot Water Boilers, sold by S.P The larger the Steam drum of the boiler, the better the boiler is capable of large steam swings.
A typical steam boiler consist of a burner used to provide heat source to the water. Horizontal water and steam drum to store feed water and steam; bundles of steel tubes acting as a heat exchanger between hot fumes and water.
One is the water tube steam drum and the other is a waste heat steam drum. Both types of steam drums have the primary and critical purpose of the mechanical phase separation of the water and steam mixture which flows from the Heat Recovery System Generator (HRSG) evaporator into the drum or fired boiler.
In the water tube boiler, boiler feed water flows through the pipes into the drum. The circulated water is heated by the combustion gas to form steam in the steam area in the drum. This boiler is chosen if the steam demand and steam pressure are very high as in the case of a boiler for power plants. A very modern water tube boiler designed with a steam capacity between 4,500-12,000 kg / hour, with very high pressure. Working of water tube boiler
Water tube boiler is a type of boiler in which water passes through the boiler where the tubes are placed in combustion chamber. They are Babcock & Wilcox boiler : Babcock and Wilcox, this type has a single drum, with feed water drawn from the bottom of the drum into a header that supplies inclined water-tubes. The water tubes supply steam back into the top of the drum.

Boiler. In a conventional steam power plant, a boiler consists of a furnace in which fuel is burned, surfaces to transmit heat from the combustion products to the water, and a space where steam can form and collect. A conventional boiler has a furnace that burns a fossil fuel or, in some installations, waste fuels.
The SCHNEIDER Eckrohrkessel is a state-of-the-art natural circulation boiler and it is used as a generator of steam and hot water. The tube cage of this type of boiler is constructed from prefabricated furnace and convection heating surfaces.
Johnson boiler: one of the first "modern" classes of high-pressure marine oil-fired water-tube boilers. They have a single steam drum above a single water drum. Their small-diameter water-tubes curve outwards on each side to form a cylindrical furnace. As there is no grate or ashpan beneath, firing must be by oil.
A water tube boiler runs off of water tubes that are heated externally by fire. The tubes connect to a steam drum and a mud drum, and steam is produced in the upper drum. The water in the tubes creates steam directly, instead of tubes heating water as is the case in a fire tube boiler.
