It is based on a horizontal external combustion smoke and fire tube boiler, and water cooled walls are installed on both sides and rear of the boiler shell to form an external furnace, forming a structural form of water and fire tube combination.

The horizontal water fire tube boiler has a compact structure, convenient manufacturing, transportation, and installation, fast ignition and start-up when in use, and high thermal efficiency. But its shell is directly heated by flame, which is prone to defects such as bulging; The temperature difference on both sides of the rear tube plate is large, and the cooling conditions are poor, making it easy to crack. The cleaning industry currently has some improved structures for this type of boiler.
