Which industrial sites are water tube boilers and fire tube boilers suitable for?

Water tube boilers and fire tube boilers are two types of boilers. Due to the differences in the internal structure of these two types of boilers, the applicable places and industries also have certain differences. For specific industries where water tube boilers and fire tube boilers are suitable, listen to the suggestions of Zhengzhou Fangkuai Boiler Factory.

Water tube and fire tube boiler are defined by the difference of the medium in the tube. The water tube boiler is the pipe passing water, and the water in the pipe is heated by the external flue gas convection/radiation heat exchange. The fire tube boiler is the pipe passing the flue gas, letting The flue gas heats the medium outside the tube to realize heat exchange. The fire tube boiler has a simple structure, large water and steam volume, good adaptability to load changes, and lower water quality requirements than water tube boilers. It is mostly used in the production process of small enterprises and domestic heating. . The heating surface of the water tube boiler is convenient to arrange, and the heat transfer performance is good. It can be used in the working condition of large capacity and high parameters in structure. But it has higher requirements for water quality and operation level. In order to help everyone understand, Zhengzhou Fangkuai Boiler Plant summarized the following points:
       (1) The pressure of water tube boiler has a wide range of adaptability, which can break through the pressure limit and meet the steam supply requirements of 2.5MPa or more. Fire tube boilers are limited by material wall thickness and pressure, and are used for pressures below 2.5MPa;
       (2) Fire tube boilers are shell-type boilers. Due to the limitations of the current equipment and tooling of various boiler manufacturers, it is more difficult to manufacture a fire tube boiler that is too large, usually below 35t/h. The water tube structure boiler can realize the large-scale boiler, and the boiler above 35t/h usually adopts the water tube structure; (3) The fire tube boiler has the characteristics of compact structure. Under the same output, the appearance and equipment weight are lower than the fire tube boiler. Due to the larger volume of the water tube boiler, there is more space for arranging the superheater, so the water tube boiler occupies a relatively large boiler room.
