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.

1. High Thermal Efficiency
1.1 The boiler is circulation heating in liquid phase, there is no heat loss leaded by condensing, thermal efficiency is high, and the boiler is very safe when operating.
1.2 The boiler shell use aluminum silicate board for heat preservation, low heat loss.
3.2 Equip with economizer, make full use of flue gas heat, decrease the exhaust smoke temperature.

2. Large Combustion Chamber
The boiler combustion chamber is composed with large diameter coil, enough fuel combustion space, sufficient combustion, high thermal efficiency. Moreover, the boiler adopt positive pressure combustion, improve the combustion efficiency.

3. Excellent Coil Design
The spiral pipes are made of small diameter multi-head steel tubes, good thermal expansibility, low stress, safe and reliable.
 

4. Sufficient Output
The boiler adopt horizontal type three pass structure, improve the heat utilization efficiency. Large heating area, good heat transfer, achieve high thermal efficiency and sufficient output.

5. Multi-function Safety Explosion-proof Equipment
Equip with explosion proof equipment at the back of boiler, prevent deflagration in furnace, discharge high energy, to ensure the boiler operate safely and efficiently.

6. Perfect Automatic Control
The boiler adopt PLC full automatic intelligent control cabinet and interlock protect system, has the protect function on oil temperature, medium temperature, pressure, etc, adjust conveniently.

7. Convenient installation
The boiler is package boiler, compact structure, covers small area, convenient for installation and maintenance.
