Fire Tube Boilers. Fire tube boilers are the backbone of low pressure steam and hot water applications. The flue gases pass through the furnace and various smoke tubes. Typically, such boilers provide saturated steam or hot water. However, superheated steam supply is possible. With ERK Tubes such boilers can be very compact and low cost.
The segmentation of a steam boiler is based on the type i.e. Water Tube and Fire Tube Boiler. The ability to generate high pressure and dry superheated steam makes water tube boiler attractive in power generation, chemical and refining industries. In water tube boiler, water flows through tubes which are heated by surrounding hot gases.

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 is a kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is just opposite of fire tube boiler. In this boiler, boiler feed water flows through the tubes and enters the boiler drum. The circulated water is heated by the combustion gases and converted into steam at the vapour space in the
Generally, hard fuel is fired at the grate. This is the first heating process and it produces flue gases. Then generated flue gases pass through the fire tube. This flue gas can pass from one side to another side, inside the boiler fire tube. Boiler fire tubes can transfer 80 to 90 percent of total heat to the water.
Industrial boiler systems can cope with much higher pressures than pressure cookers. These them back in the 2nd smoke tube pass. On the front of the boiler is an external reversing using process heat generated by steam boiler systems the individual applications are far more
Boiler Types - Fire Tube Boilers. Firetube boilers confine the combustion process and gases in tubes, and water circulates these tubes. Some fire tube boilers have turbulators inside of the tubes to cause turbulence of the flue gases. That increases the heat absorption into the water, which makes the boiler more efficient.

Types of Boiler . Here are the types of boiler systems. Steel Boiler - there are two types of steel boilers: Fire-Tube Boiler; The combustion gases or hot gases of a fire-tube boiler passes through straight tubes while water surrounds it. As a result, the water surrounding the tubes gets heated up.
Fire-tube boilers are limited to about 2.4 MPa (350 psig) pressure and are used primarily for heating and process steam applications. This chapter provides information on a variety of topics that are useful for process engineers who are involved with the design, installation, or troubleshooting of a boiler system.
Boiler Types. Fire Tube Boiler. One of the most basic types of boilers, the fire tube boiler is also one of the oldest designs. The burner shoots the flame into a tube that is immersed in water contained in the main vessel of the boiler itself. There may be multiple fire tubes.
A firetube boiler is a boiler that combusts the fuel in a chamber and then passes the hot exhaust gasses through a series of tubes with water on the outside of them. They generally operate at less than 300 psi and produce steam with moderate steam
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.
Scotch Marine Boiler. Scotch marine boiler is a fire tube boiler. It is also a scotch or tank type boiler which is used for the marine works. The reason behind, it is used for marine work is its compactness, efficiency in operation and its ability to work in any type of water.
Fire tube boiler vs Water tube boiler. Boiler is a closed vessel used to produce steam. Industrial boilers mainly can be classified as a fire tube and water tube boilers. The difference between fire tube boiler and water tube boiler depends on many factors.
Water Tube Boilers - In contrast to fire tube boilers; a water tube boiler uses the water rather than the heat which is contained inside of a system of interconnected tubes. The heat moves around the tubes, thereby heating the water within the tubes and gradually transforming it into steam.
You will find boiler, boiler with flames, hot blast heater, blast furnace, firebox boiler, boiler control, oil fired boiler, packaged fire tube boiler, heating furnace, skid-mounted boiler, steam boiler, super heater, etc. How to Create Professional Looking P&ID. Boiler is a closed vessel in which water or other fluid is heated.
The three types of fire tube steam boilers are horizontal return tubular boiler, scotch marine boiler, and vertical fire tube boiler. All fire tube boilers have the same basic operating principles. The heat produced by the gases of combustion pass through the tubes while the water surrounds the tubes.

A boiler must be carefully and properly prepared for start-up. This is a step by step process, and all plants will have their own procedure based on the role that the steam system plays in that plant. It is important to note that the boiler, and steam system, are often prepared and started before the process units in a large
In a water-tube boiler, it 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. When fire tube boilers run low on water, the metal in the boilers shrinks.
Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of the
Fire tube boilers represent one of a number of pressurized equipment options used to heat water or convert water into steam under controlled conditions. In fire tube boilers, combustion gases pass inside boiler tubes, and heat is transferred to water on the shell side.
Roll Beading Fire Tube Boiler Tubes. This will prevent any ligament damage during the beading process. Once the beading has been completed, the tubes can be re-rolled with a straight expander. This final operation requires only a few seconds per tube, to ensure uniform leak-proof joints.
