An early development in watertube boilers was bent tube design. This boiler has two drums, an integral furnace and is often referred to as the 'D' type because of its shape . The furnace is at the side of the two drums and is surrounded on all sides by walls of tubes.
As the superheated steam passes through the tube bundle, it gives up heat to the boiler water in the water drum. The boiler is protected from the high temperatures of combustion by the refractory. Refractory lines the inside surface of the inner casing enclosing all of the furnace area and extending to the outer row of generating tubes.
Flexible Watertube (Bent Tube) Boilers Flexible watertube boilers are a common type of boiler used for heating applications because of their resistance to thermal shock. Flexible watertube boilers are available in size ranges from 2 to 9 MMBtu/hr input. Flexible watertube boilers are available for low pressure steam or hot water applications.
Fire tube boilers produce steam rates up to 26,000 pounds per hour. Water tubes, also known as high pressure boilers , have an inverse structure compared to fire tube boilers. Water flows through tubes that are surrounded by a cavity of hot gases. Water tube boilers are capable of producing 10,000 to 1,000,000 pounds of steam per hour.
Packaged boiler types. While there are various types of small packaged equipment that produce steam, this article focuses on two primary types: watertube and traditional firetube boilers. In watertube boilers, water flows through the tubes, while combustion gases pass over the tubes.

Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler.
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.
Watertube boilers are great and one thing, turning water into steam. Watch today as Ritchie and Steven talk about how a watertube steam boiler works. Boiler's are just over sized tea kettles
The steam generated by the boiler can also be use for cleaning, and heating of the seawater in the freshwater generator thus evaporating it to make it potable water. There are two types of boiler mainly use in the Marine Industry, The water-tube boilers and the fire-tube boilers. The most common of which is the water-tube.
Water tube boilers are used for high-pressure boilers. Fuel is burned inside the furnace, creating hot gas which heats up water in the steam generating tubes.

meet the turbulator Turbulators are designed to create and maintain turbulent flow and help to increase the tube-side heat transfer efficiency. A turbulator is a device which is inserted on the tube side of firetube boilers, shell & tube heat exchangers and other types of heat transfer equipment.
For more information on older boiler types including back boilers, wall mounted and free standing systems, visit our guide to other types of central heating boilers. Condensing Boilers Condensing boilers typically extract over 90% of the heat from the fuel they burn, making them both cost effective and energy efficient.
3. There are two different types of boilers: fire tube and water tube. A fire-tube boiler works when hot gas passes from a fire through tubes running through a sealed container of water. The heat of the gas is transferred through the walls of the tubes by thermal conduction, heating the water to create steam 2. A water tube boiler circulates
Boiler accidents can occur when the boiler is allowed to operate without adequate water in the boiler. Proper functioning low water cutoffs are essential to prevent these types of accidents. Boiler damage can run from severe buckling and deforming of the boiler to complete meltdown or potential boiler explosions.
