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. A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion.
In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads. When the handle of the cocks are vertical, they are in operation and the water level in the tube corresponds to water level in the shell. A red mark on the glass tube indicates the safe water level. C) FUSIBLE PLUG: The function of the fusible plug is to extinguish the fire in the event of the boiler shell failing below a certain specified.
In order to increase the insulation of boilers, we use the water wall tubes. In water wall tubes, water flows and takes away the heat surrounding it. Thus the heat inside the boiler does not get transmitted to the outside of the boiler.
These are of three designs namely: water cooled with refractory covered studded tubes; Close pitched exposed. The main feature of the boiler is that the furnace of the boiler is surrounded by water and therefore there is no requirement of refractory material. It is a single phase pass boiler, which means that the hot gases pass just through the horizontal tube stack before going to the exhaust.
Water-tube boilers; in which the water circulates through tubes exposed to the furnace heat. The Babcock and Wilcox boiler (Fig. 7) is typical of this variety. (2) Fire-tube boilers; in which the hot gases pass through tubes surrounded by water.
The ordinary locomotive boiler (Fig. 6) illustrates this form.

Alternatively, in a Watertube boiler, water flows in the inside of the tubes and the hot gases from combustion flow around the outside of the tubes. Water-tube boilers also have a downcomer tube that connects the steam drum to the feedwater drum. If the steam cools and condenses back into water droplets, that water can drain from the steam drum to the feedwater drum via the downcomer tube.
This allows that water to re-enter the boiler’s water supply, go back into the tubes, and once again. In smoke tube type flue gases are inside the tubes and water is on the shell side while in the water tube type, water is in the tube and flue gases are on the shell side.

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 examples of water tube boilers are a La-Mont, Benson, Stirling, Babcock and Wilcox, Yarrow and Loeffler boiler.
In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3, psi, sometimes higher) are required. Boiler control systems are generally broken down into three main functions: burner controls, feedwater controls, and flame safety controls.
The three are interrelated as far as actual operation of *the boiler is concerned, but they are basically independent systems. They will, therefore, be discussed separately here. Burner Control Systems. The function of the pressure gauge is to indicate the pressure of the steam inside the boiler. Feed check valve: It stops and allows the flow of water inside the boiler. Water level indicator: It indicates the level of water in the boiler. It is placed in front of the boiler.
