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 …
The water tube boilers are mainly used for generating steam with high temperature as well as pressure. The internal structure of this boiler includes a tiny steam drum, small width tubes. The components of this boiler generate high-volume vapor for high-capacity applications. These boilers are most frequently used boilers, which has replaced several boilers like fire tube due to some reasons like the weight of …
The examples of the fire tube boiler are the simple vertical, Cochran, Lancashire, Cornish, Locomotive, Scotch marine, and Velcon boiler. Water-tube boiler: The water-tube boiler is those boiler in which the water is present inside the tubes and fire or hot gases surround these fire tubes.
The following formula may be used to determine the boiler horsepower required for steam used in a pelleting operation: Boiler horsepower = (F x M) / (0.83 x 34.5) F = Pounds of feed pelleted per hour. M = Percent of moisture as a decimal to be added by steam. 0.83 = An approximate correction factor for make-up water at 50 degrees F. 34.5 = The amount of water evaporated in one hour at 2120 F, which equals one boiler …
The main application of the water-tube boiler is that it is being used at several places Such as paper mill, Sugar mill, a textile factory, Central heating enterprise, Chemical industry, A power plant, and so on. Complete Article. Babcock and Wilcox Boiler Lamont Boiler.
Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g. The higher the pressure, the greater the energy contained in the blowdown water.

For sugar mill power station project, our biomass power plant boiler can burn biomass fuels with low SOx and NOx emissions such as bagasse. In the biomass water tube boiler, the air and fuel (bagasse and/or coal) are burned in a furnace. The hot products of combustion are guided from the combustion zone over the exterior surfaces of the water-tubes.
Jan 09, 2019 · 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. The ignition process occurs outside the pipe. The heat produced is used to heat a pipe containing water. The feed water was previously conditioned first through an economizer.
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
Jul 25, 2017 · Economizer (heat exchanger) is the boiler accessory used to recover the heat of flue gas that leaving the boiler by heating feed water. The efficiency of a boiler can be increased with an economizer. 60C rise in feed water temperature with the help of economizer can save up to 1% of fuel.
Dec 28, 2020 · Boilers vary in size and design (water tube, fire tube, etc.) depending on pellet system capacity. Occasionally multiple boilers are needed to meet the steam requirement of the pellet mills. As a general rule of thumb, the capacity of a boiler should be 3.5 to 5.0 HP per ton of pelleted feed per hour.
Used BABCOCK & WILCOX water tube boiler 30,000lbs superheated steam (per hour), heating surface: 6821 ft2 Operating pressure 180 psi / at 450 deg. F The superheaters were replaced (2011) Boiler was extensively overhauled and refurbished in с 2013.

Feb 01, 2014 · What is a boiler for Textile mills ? List of boiler machine for Textile Mills and Apparel Industry is closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is superheated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …
