YYL(W) type vertical(horizontal) type fuel oil(gas) heat boiler
Rated thermal power: 0.7MW - 29MW (60xl04Cal/hr - 2500xl04Cal/hr)
Design pressure: 0.6MPa - 1.6MPa
Specific parameters are shown in Table6
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.
