What is a fire tube boiler
Fire tube boiler (also known as boiler shell boiler) and water tube boiler are the two main types of industrial boilers, users can choose fire tube and water tube boiler for specific applications, how to choose the appropriate type of boiler is not an easy thing. It is hard to argue that one of these two types is better than the other: fire-tube boilers and water-tube boilers both have their own unique advantages and disadvantages, and a comprehensive understanding of the differences between these two types of boilers will help to make a correct procurement decision.ZOZEN boiler produces all kinds of fire tube boilers and water tube boilers for sale.
In a fire tube boiler, the high-temperature flue gas from the burner flows through a threaded pipe surrounded by water and heats a mixture of water, steam, or soda outside the pipe wall to produce steam or hot water.

Advantages
1.Simple structure, compact size, easy to install, low production and construction costs.
2.Fire tube boiler has low failure rate, simple maintenance and low operating cost.
3.The screw pipe of high efficiency heat transfer element developed by ZOZEN has been adopted to extend the time of flue gas retention in the furnace and improve the thermal efficiency effectively.
4.Using large diameter corrugated furnace, reduce the boiler thermal stress, with sufficient steam storage space and heating surface, the boiler can efficiently produce higher thermal power and high quality steam.
Advantages
1.The boiler capacity and pressure of fire tube boiler are limited by the structure itself, so it is suitable for boilers with evaporation capacity less than 20t/h and pressure less than 2Mpa.
2.Since the water volume of a fire tube boiler is larger than that of a water tube boiler, the time required to increase steam pressure is relatively long, which means that the boiler takes longer to recover from cold start to operating temperature, and it cannot respond quickly to continuous large load changes because of the large amount of water.
Fire tube boilers and water tube boilers have their own advantages and disadvantages. Each enterprise should select the appropriate boiler type according to the actual requirements of its own production line, such as steam demand, reasonable boiler room area, boiler operation cost and easy maintenance, etc. As one of the leading industrial boiler manufacturers, ZOZEN boiler always adheres to providing customized boiler system services for customers. The fire-tube boilers and water-tube boilers produced by ZOZEN are widely used in all walks of life in the world.
