The heat transfer medium path and structural design are different. In water boiler tubes, water flows inside the tubes, and the high-temperature flue gas outside heats the tubes. In fire boiler tubes, the burning gas flows inside the tubes, heating the water outside the tubes.
What Are The Differences In Performance and Application Scenarios?
Fire boiler tubes are suitable for low-pressure scenarios (such as small-scale industrial and home heating), with faster startup and low cost, but they are inflexible and can only have fixed structures. Water boiler tubes are suitable for high-pressure and large-capacity scenarios (such as large power plants and large industries), with higher working efficiency and better safety. The design is very flexible, but the complex maintenance cost is high.
