The examples of the fire tube boiler are: simple vertical boiler, Cochran boiler, Lancashire boiler, Cornish boiler, Locomotive boiler, Scotch marine boiler and Velcon boiler. (ii). Water Tube Boiler: In water tube boilers, the water is present inside the tubes and the fire or hot gases surrounds these water tubes.
Boiler inspections are dirty, usually hot and wet, confining and always a humbling experience, but they are absolutely essential. (James N. Tanis, Procedures of Industrial Water Treatment , Ltan Inc., 1987) W ith the heating season starting, it is only appropriate to discuss boiler inspections.
The versatile drum orientation allows Indeck's "O" model boilers to meet unique project requirements for shop-assembled or field-erected boilers. The "O" type watertube boiler is capable of producing steam up to 1,000,000 lb/hr at design pressures over 2000 PSIG and superheated steam over 1,050°F.

Special features of water tube boiler: Water tube boilers have the high evaporating capacity (20,000 to 40,000 kg/h) compared with other boilers. The operating pressure lies between 11.5 to 17.5 bar. The draft losses are minimum. The defective tubes in water tube boilers can be identified and replaced easily.
Package boilers are commonly called water or fire tube Boilers. Water tube boilers use convection heating, which draws the heat from the fire source, and passes against the generating tubes of the boiler, causing water inside those tubes to boil off into steam. The fire tube boiler arrangement utilizes conduction heating which transfers heat from physical contact.
The design of water tube boilers is strictly opposite to that of fire tube boilers design. 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.Operating Principle: Natural water circulation..
What is a water tube boiler? Water tube boilers were developed for a variety of reasons, including the need for higher steam pressures, higher steam generation rate, superheated steam. these types of boilers have quicker response to load changes. We briefly discuss about Water tube boiler parts and functions.
Steam Boilers easy. 10. Easy transportation: Water tube boilers can be easily dismantled conveniently transported and erected quickly at the site than a fire tube boiler. Disadvantages: 1. Not suitable for ordinary water: Water tube boilers require relatively pure feed wan because impure feed water forms scale inside the water tubes, consequently there will t overheating and bursting of the
TYPES OF BOILERS. The boilerman is concerned primarily with the FIRE-TUBE type of boiler. However, the WATER- TUBE type of boiler may occasionally be used at some activities. The information in this chapter primarily concerns the different designs and construction features of fire-tube boilers. The basis for identifying the two types is as follows:
Watertube boilers (also spelt as 'water tube' or 'water-tube') are used whenever a large steam production capacity is required; they are typically high pressure and high temperature boilers.
A high pressure, drum less, water tube steam boiler works on forced circulation. . Feed water enters at one end and discharge superheated steam at the other end. . Feed pump increase pressure of water to supercritical pressure. . Water directly transforms into steam without boiling . BENSON BOILER
Belleville boilers worked quite well at pressures between 12 and 16 bar, but false water level readings was a huge problem. Later Belleville water tube boiler always had an economizer on the top.
The water tube boiler generates more steam of high pressure whereas a fire tube boiler generates steam of low pressure. We will discuss the fire tube boiler, different types of firetube boilers, defects, and uses. Fire Tube Boiler. In Fire Tube Boilers, hot flue gases will be flown inside the tube and these tubes are surrounded by water. These
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low
