Fire Tube Boiler - Construction, Types and Its Working

The locomotive boiler is an inactive boiler which is used in train engines. This type of boiler is capable while producing steam as well as it is solid. The design of the locomotive boiler is horizontal multi tubular. The main advantage of using this type of boiler is low cost for construction, installation and steam capacity is high.

Boiler Classification and Application - CED Engineering

in boilers, but the most common types of fuel include coal, oil, and natural gas. During the combustion process, oxygen reacts with carbon, hydrogen, and other elements in the fuel to produce a flame and hot combustion gases. As these gases are drawn through the boiler, they cool as heat is transferred to water.

The Importance of Coal Analysis to Boiler Designers

Jul 03, 2009 · Coal is a heterogeneous fuel and has only an assumed structure – C & H vary highly; C & H in Coal can be only be known if you do an ultimate analysis, and the way in which these hydrocarbon behave can be different from one coal to the other. This will depend on its reactivity and formation. Formation of coal has vast impact on boiler design; the Gondwana coals are different from American and European. (Coal …

The boiler design can also be identified by the shape of the tube configuration, with the common types being called A, O, and D style boilers. The cast iron sectional boiler is neither fire tube nor water tube though it has some operating characteristics of a water tube boiler. The water is inside the sections and the fire is outside the sections.
