What is a water tube boiler?
The operation mode of a water tube boiler is exactly the opposite of that of a fire tube boiler. A water tube boiler is such a kind of boiler where the water is heated inside tubes and the hot gas surround them.The high-temperature flue gas heats the water in the pipe to produce steam or hot water.
Parameter comparison:

Advantages
1. The main advantage of this boiler is its large capacity, up to 110T /h, and can withstand higher pressure and temperature.
2. It can produce steam quickly and produce saturated or superheated steam according to actual requirements. Meanwhile, with good adjustment abilities, the boilers can precisely track load fluctuations.
3. The heating area of water tube boilers is the surface of tubes placed in the furnace instead of the boiler drum, which has good heat transfer effects and safety performance.
4. The boilers adopt membrane water wall structure. The reasonable design of the size of drum and steam-water separator can increase the steam quality.
Disadvantage
1. The boiler is complex in design and structure and large in volume, resulting in relatively high cost of manufacturing, construction and maintenance.
2. Water tube boilers should adopt water treatment equipment to avoid the problems caused by boiler scale.
