Structural features of this series of products

• There are two types of structure: vertical(YYL) and horizontal(YYW).
• The boiler surface adopts the tightening-tube-arrangement with spiral structure. The chimney adopts the three-pass arrangement.
• An air preheater or a water/steam transformer is arranged behind the boiler, reducing the temperature, improving the thermal efficiency of the boiler.
• The quick opening door or the observation door is equipped for the convenience of checking the internal inspection and maintenance.
