What is the main feature of a water tube boiler?

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 the hot flue gases and finally converted into steam.

What is the pressure range for water tube boiler?

The capacity of the water-tube boiler can range from 5 to 120 t/h of steam, with an operating pressure of between 0.5 to 120 bar(g). The boiler can also be used in hot-water systems.

How are boiler tubes made?

How Are Boiler Tubes Made? Both medium-pressure and high-pressure boiler tubes undergo the same initial process of manufacturing, which includes fine drawing, surface bright, hot rolling, cold drawn and heat expansion. Quenching is done to increase the hardness of the high-pressure boiler tube.

What is difference between fire tube and water tube boiler?

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 and produce steam.

What is difference between fire tube boiler and water tube boiler?

The main differences between the fire tube and the water tube boiler are the hot gases flow inside the tube and water surround them in the fire tube boiler whereas, In the water tube, water flows inside the tube and Hot gases surround them.

What is accessories of boiler?

Boiler accessories are devices and plants that are installed with boilers to improve the operating condition and overall efficiency of the boiler plant. Boiler accessories are devices that are installed along the boiler and the surrounding area to increase the efficiency of the boiler.

What material is boiler tube?

Boiler tubes are seamless tubes and are made of either carbon steel or alloy steel. They are widely used in steam boilers, for power generation, in fossil fuel plants, industrial processing plants, electric power plants, etc.

How does the ‘boiler’ work to heat the House?

The boiler process Your home’s thermostat senses a drop in your home’s temperature and calls for the boiler to turn on. Your boiler powers on and uses either oil, gas or electricity to create heat. The heat from the fuel source is used to heat up water inside the boiler.

How does a heat exchanger in a boiler work?

In a boiler heat exchanger, heat is transferred from the hot gases of a combustion process to water moving through the exchanger’s internal piping system. As a result, the water heats up as the gas cools down.

How hot does a boiler get?

Firebox temperatures reach 2000 F during the combustion process, but most outside surfaces are only warm to the touch. However, some boiler surfaces can get very hot so observe the warning labels on the boiler to avoid injury. The water temperature is approximately 180 F when it leaves the boiler and 160 F upon return.

How does a radiant heat boiler work?

In radiant heat boilers, metal tubes or pipes are embedded in walls and floors, which can carry hot water or steam. A water boiler, which is usually kept in the cellar, is used for heating water. The heated water is then pushed into the circulation system through a pumping system.
