Boiler tubes are made in various sizes and arrangements relying upon the attributes of the fuel, the predetermined heating yield, and the required emissions controls. A few boilers are just fit for heating water, while others are intended to deliver steam. The traditional steam boiler has 2 sorts: fire-tube heater and water-tube heater. Fire-tube heater is anything but difficult to set-up and work. Fire-tube heater is utilized on steam trains.Water-tube heater is typically connected to boats and factories lines. Boats use the steam delivered for different procedures, for example, heating, sanitation, and so forth. Oil refineries, steel factories, synthetic plants and paper plants are some of the industries that need substantial kind of water-tube boilers
Copper used to be the most favored material for the construction of pressure vessel that was found in boiler tubes. Copper was highly favored due to its better formability and extraordinary thermal conductivity. However, its high cost gave rise to individuals to search for a less expensive substitute, for example, steel. Today, steel is used majorly in creating boilers. Steel is cheap, durable and can be welded because of which It is rising to be the top material of choice.
Fire-Tube Boilers
Fire-Tube Boilers have straight tubes in a series set inside an outer shell filled with water. The main aim of this set-up is to allow the hot flammable gases to flow through these tubes. Fire-tube boilers are subdivided into three groups.
Water-Tube Boilers
Around the exterior of a large number of water-filled tubes, Water-tube boilers circulates hot combustion gases. Water-tube boilers are generally utilized as a part of industries, for example, sugar mill, chemical industry, paper mill, a textile factory, power plant, and so on.
