How Water Tube Type Boilers Work. If the steam cools and condenses back into water droplets, that water can drain from the steam drum to the feed water drum via the downcomer tube. This allows that water to re-enter the boiler's water supply, go back into the
Learn MoreVelox Boiler is a forced circulation water tube boiler. Let's start with the Feed Pump. This Feed Pump supply the water at a pressure and water pass through the Economizer like Loeffler Boiler. Hot fuel GAS passes through the Economizer from the Combustion Chamber. When water passes through the Economizer Tube then water is pre-heated.
Learn MoreWorking Principle. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls.
Learn MoreBabcock and Wilcox water tube boiler working principle. The water at the bottom of steam drum flows in to water tubes through the down take header at the rear end of the drum. Thus, a continuous circulation of water from the steam drum to the water tubes and water tubes to the drum is maintained.

Type of water tube boiler Simple vertical boiler A vertical boiler is a type of water- tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation. Vertical boilers were used for a variety of steam- powered vehicles and other mobile machines, including early steam locomotives.
Learn MoreWater Tube Boilers. In water tube boiler systems, the water to be heated is enclosed inside the boiler tubes whereas the hot combustion gases exhausted by the burner keep circulating around the tube surfaces. The water within the tubes then gets heated via
Learn MoreFire Tube Boiler Construction and Working Principle of Fire Tube Boiler. The construction of a water tube boiler can be equipped with cylindrical shell, vertical, firebox in the base, space for water in the center segment, and space for steam in the higher segment. A fire-grate is located at the fire-box base as well as coal is fired-up on the firebox.

Learn MoreWater Tube Boiler Working Principle: First of all Water Tube Boiler and Fire Tube Boiler are completely opposite to its structural designs. In Water Tube Boiler water will be heated inside the Boiler Tube and heat will passes around the Tubes.
Learn MoreFire Tube Boiler. The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes. Mostly used boiler in small and medium industries with different fuels and steam pressure requirements.
Learn MoreJun 10, 2017· Special features of water tube boiler: Water tube boilers have the high evaporating capacity (20,000 to 40,000 kg/h) compared with other boilers. The operating pressure lies between 11.5 to 17.5 bar. The draft losses are minimum. The defective tubes in water tube boilers can be identified and replaced easily.

Learn MoreMachinery Spaces.com. 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
Learn MorePrecautions for Cleaning Water-tube Boilers NOTE: The following is adapted from a report based on work by the Yale Occupational Health Program with CEUI/SEIU Local 511, a state employees union in Connecticut, in 1990 and 1992. A. Shut-down and cooling. Boilers must be shut down several days prior to cleaning to allow cooling.
Learn MoreWater 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
Learn MoreA boiler can be defined as a closed vessel in which steam is produced from water by combustion of fuel. A boiler is used in many industries such as in steam power generation, in sugar industries, in textile industries for sizing and bleaching etc. and in many other chemical industries.
Learn MoreFire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more compacts.
Learn MoreJun 10, 2017· Construction: A horizontal steam and water drum: this is the main part of the boiler. It is supported by a steel structure at a certain height and is independent of brickworks. The size of the boiler drum is small as compared with the boiler drum of a fire-tube boiler of the same capacity. It has water
