Aug 28, 2019· What is a Water Tube Boiler Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high.
Boiler Pipe Material Specification and Application. Boiler steel pipes includes medium pressure boiler pipe and high pressure boiler pipe, it is often manufactured in seamless procedures, welded steel pipe is not applicable. It has been widely used at heat exchanger pipe and tubing services, tube exchanger bundle, high pressure boiler, economizer, super heater, petrochemical industry pipes, etc.
Mar 04, 2020· 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
Steam Boiler In India April 10, 2019 April 10, 2019 No Comments on specification of 10tph fire tube boiler BOILERS | Energy-Models 2019-4-5 · Figure 2.3 Water Tube Boiler: 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
Apr 23, 2016· The difference between fire tube boiler and water tube boiler can be done on various points. These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler is very crucial.
In a water tube boiler, specifically, ones designed by Miura, the boiler contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn’t melt and create problems.
Additionally, since the tube holds less water than the water tank of a fire tube design, it takes less time to turn that water to steam — and by extension, less fuel. A water tube boiler produces steam in as little as five minutes, compared to an hour or more for fire tube boilers. As a result, fuel savings costs can be significant over time.
Mar 19, 2016· Difference between Fire Tube Boiler and Water Tube Boiler: Fire Tube boiler. Water Tube Boiler. 1. Hot flue gases flow inside the tube and the water outside the tube. Water flows inside the tube and the flue gases outside the tube. 2. This boiler pressure is limited up to 20 bar.
Fire tube boilers are low pressure or medium pressure boiler. Water tube boilers are high pressure boiler. 3 Boiler pressure range between 20-25 bar (Low pressure) and for medium pressure boiler pressure range about 25-80 bar.
Jun 05, 2018· Comparison between Fire Tube and Water Tube Boiler can be done in 14 aspects. Those aspects are operating pressure, passage of material type in tubes, rate of steam generation, handling of load fluctuation, floor area requirement, efficiency, operator skills, design, maintenance cost are listed below in the tabular form.
Dec 07, 2016· In recent years, fire tube designs have become more compact and efficient, incorporating features like reverse flame to get the most out of the heat source. Water Tube Boilers. Unlike fire tube boiler, where the hot gas is circulated through tubes to heat water in a tank, water tube boilers involve running water through tubes surrounded by a
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low
Cochran Boiler is a simple fire tube boiler with multiple fire tubes. It is a modification of a simple vertical boiler. In the Cochran boiler, the heating surface is replaced with multiple fire tubes that’s why it is the modification of Simple Vertical Boiler. Cochran boiler has …
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.
Fire-tube boiler: Fire-tube boiler is those boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.
A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.
Water tube boiler design and working In a typical Water tube boiler design as shown in the figure, it consists of two drums the steam drum and the water or mud drum. On this design straight tubes were rolled into mud drum, and the front headers were connected to the steam drum.
