A Field-tube boiler (also known as a bayonet tube) is a form of water-tube boiler where the water tubes are single-ended. The tubes are closed at one end, and they contain a concentric inner tube. Flow is thus separated into the colder inner flow down the tube and the heated flow upwards through the outer sleeve.
We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt

Field Erected Boiler The ASME Code allows for a boiler to be built, provided certain requirements are followed, on site as opposed to the boiler manufacturers facility. For many years, this meant a high pressure watertube boiler.
FIELD ERECTED BOILERS - DESIGNED TO ORDER If site requirements or specific fuel types dictate a field erected boiler, TIBS offer a proven track record in the design, supply, installation and commissioning of this boiler type.
Water tube boilers are available in a variety of arrangements including package shop assembled, modular and full field erected units that can meet various space and process applications. These watertube boilers are designed to burn a wide range of fuels such as:
A field erected boiler is a boiler where some of the non-pressure and pressure parts (such as water and steam drum) are constructed at the site area. Generally, large water boilers are field erected. Field erected boiler units are the only boiler available for any technologies above 200,000 pph.
Aug 22, 2018 · 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.
