Fire tube steam boilers (definition)

Fire tube steam boilers - this is a type boilers, in which hot gases produced by burning fuel pass through pipes washed with water, which is then converted into steam. These boilers are widely used to generate steam in industrial plants and thermal power plants.

Fire Tube Steam Boilers: Definition

• Principle of operation: hot gases from the firebox pass through tubes (fire tubes) that are washed with water. As a result of heat transfer, the water heats up and turns into steam.
• Design: consists of a firebox, fire tubes, a boiler drum (where the water is located), and a steam pipe.
• High thermal efficiency: due to maximum heat transfer from hot gases to water.
• Ease of operation and maintenance: relatively simple design and fewer moving parts compared to water tube boilers.
• Pressure limitation: Typically such boilers are used at low and medium steam pressure.

Fire tube steam boilers are often used in industrial processes to generate steam, as well as in the power industry to produce heat and electricity.
