Understanding Boiler Circulation. October 1, 2013. Boilers generate steam using different methods to circulate the steam-water mixture through the evaporator tubes. These methods include natural circulation (Figures 1, 2a-2c), forced circulation (Figure 3a), and a once-through design.
Fire-tube boilers have the advantage of being easy to install and operate. They are widely used in small installations to heat buildings and to provide power for factory processes. Fire-tube boilers are also used in steam locomotives. In the watertube boiler, the water is inside tubes with the hot furnace gases circulating outside the tubes

The biggest disadvantage of the Smithies boiler is the limited water capacity of its inner barrel as compared to other boiler types with similar external dimensions. Vertical Type The vertical boiler is a simple type which consists of a firebox at the bottom and a copper barrel with a smoke tube.
The boiler has no power: The circuit breaker or fuse controlling the furnace may have tripped or blown. Reset the tripped circuit breaker or replace a blown fuse. Water level low: Maintain water level in the boiler at half-full.The boiler's automatic filling system, controlled by the pressure-reducing valve, should maintain the proper water level at 12 to 15 psi of pressure.

A water-tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Water-tube boilers are generally used for high-pressure boilers. Fuel is burned inside the furnace, creating hot gas which heats up water in the steam-generating tubes.
Furnace wall water cooling - eliminates refractory and related maintenance. Gas-tight setting membrane - inhibits dew-point sulfur corrosion and outages caused by gas leaks. Rugged steel-based frame - supports boiler and allows jacking and skidding. Outer lagging - galvanized, weather-tight for outdoor installations. Drum internals - ensure positive circulation, low moisture, high
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

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
Working Principle of Water Tube Boiler . The working principle of water tube boiler is thermal siphoning (circulation of natural water). Basically, this type of boiler includes two drums namely steam, lower or mud drum. The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At

Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy
A sight glass or water gauge is a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within. Regulation Every boiler is to be fitted with at least 2 independent means of indicating the boiler level in it: one of which is to be a glass gauge.
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.

In this type of boiler, the gases of combustion pass through tubes that are surrounded by water. There are a number of auxiliary boilers of the fire-tube type in use in diesel-driven ships. Figure 18-12 illustrates a cutaway view of the fire-tube boiler shown in figure 18-11. Water-Tube, Natural-Circulation Boilers. Water-tube, natural
On the water/steam side, there is a high potential for oxidization of boiler tubes due to high temperature steam and the corrosive action of chemicals in the water supply.
The total heating surface of a boiler includes all parts of the boiler which are exposed on one side of the gases of combustion and on the other side to the water and steam being heated The heating surface incudes: generating surface, generating tubes, screen tubes, waterwall tubes, support tubes, superheater surface, and economizer surface

Boiler Safety and Role of Low Water Levels. Hence, a Low-water condition has the potential to melt the steel tubes. Controlling the boiler drum level is complicated as the "water level" in a steam drum is actually a fairly unstable mixture of water and steam bubbles that shrinks and swells as the pressure changes. This is because of the

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.
Our broad line of economizers covers the spectrum of boiler sizes, ranging from very small hot water boilers with burner inputs of 200,000 BTU/hr to large boilers delivering steam at 250,000 lb/hr. In addition, Cain produces boiler feedwater systems, condensate tank and pump systems, exclusive sootblower assemblies, and unique modulating
An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: Example 3.12.3. A boiler water sample has an unneutralised conductivity of 5 000 μS/cm at 25°C.
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.
