Marine boilers are of two types namely the water tube boiler and the fire tube boiler. The water tube type boiler is used for high-pressure, high-temperature, high-capacity applications. The Main boiler design depends on its application, ie. for motor ships, a small fire tube boiler would be satisfactory.
17.5 kg/cm2. Water tube or "water in tube" boilers in which the conditions are reversed with the water passing through the tubes and the hot gasses passing outside the tubes (see figure 2.3). These boilers can be of single- or multiple-drum type. These boilers can …
A fire-tube boiler is a boiler that passes hot gases through tubes to heat and vaporize water. Contrast a water-tube boiler and a fire-tube boiler. A downcomer has cooler water which is more dense so it falls, and a riser has hotter water which is less dense so it rises.
Two-Drum Bent Tube Boiler An upper and lower drum are interconnected by a number of tube banks. The furnace is surrounded by water tubes, which is often referred to as an "integral-furnace" because the furnace tubes are an integral part of the water circulation circuit. The integral design, not restricted to the two-drum boiler, has advantages

The ASME boiler code states the projection of tube ends into boiler drums and headers shall not be less than 1/4" and not more than 1/2". These are measured on the high side of the drum shell and before the tube end is flared.
With subcritical and supercritical steam pressures, temperatures and capacities, our top-supported, one- or two-drum designs use challenging fuels in a circulating bed of inert particles to control combustion and emissions. The CFB boiler is ideal for high sulfur and high ash fuels and various waste fuels, wood, biomass, gob and culm.
necessary when it is time to choose. This paper reviews watertube and firetube boilers and compares their strengths and their limitations. Watertube boilers contain the water and steam inside a network of mud and steam drums plus the interconnecting bent water tubes. The hot combustion gases used to heat the water circulate outside these tubes.
Boiler feedwater being introduced into the steam drum. Cooler water sinking through tubes called "downcomers." Water absorbing heat from the tubes, then the heated water rising to the steam drum. Due to the critical need for water, modern boilers are equipped with automatic low-water trip switches.
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 boils 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

Feb 24, 2012 · A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. 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
Fig. (2) Shape of fire-tube 2.1.3 Water-tube boilers: • Water-tube boilers have water running through the tubes and fire or gases of combustion surrounding the tubes. The water tubes are connected into a steam drum at the top and a mud drum at the bottom. The fire is in the Combustion chamber. The boiler design can also be
"A" Style - One steam drum and two lower drums set in shape of "A". Furnace is in the center of boiler with two generating banks. "O" Style - One steam drum and one lower drum, centered over each other with furnace in center and two generating banks.

The water within the water drum, and the connecting pipes to the other two upper drums, are heated, and the steam bubbles produced rise into the upper drums where the steam is then taken off. The bent tube or Stirling boiler allows for a large surface heat transfer area, as well as promoting natural water …
Oct 09, 2015 · Two drum cfb boiler has the feature of low cost or high sulphur solid fuels, excellent efficiency, with low emissions,high operational reliability, low NOx emissions, low ash carbon content. This type of boilers are of large capacity up to 280 t/h and widely used for large scale central heating or power generation.
Sep 28, 2009 · This is an old video (but good!) my dad gave me, it shows what is happening inside of a steam boiler. Hope that you find this interesting or educational.
Unlike firetube boilers, watertube boilers pass water through the tubes, which are then heated externally by hot gas from the furnace flue gas. The heated water rises into a steam drum, where it can then be reheated by a superheater to achieve even higher steam temperatures - this superheated steam is a dry gas most commonly used to drive
