>> Introduction
SZL series double drums boiler is horizontal type large capacity water tube boiler with high steam quality. Compare with the previous boiler, the new type SZL boiler adopts membrane water cooling wall, low thermal inertia design, and water cooling combustion chamber. Boiler with steam capacity lower than 4t/h is fast assembly water tube structure, the boiler with steam capacity between 6~25t/h is consisted of upper part (boiler heating part) and lower part (combustion equipment). This series boiler has reached the international advanced level on technology and performance, has the advantages of compact structure, convenient installation, short install period, low cost, and environmental protect.
Introduction
>> Features
Membrane water wall

1. Membrane water wall

Adopts water cooling combustion chamber, increase the radiant heating area, improve the output and thermal efficiency.The boiler body use membrane water wall structure, good sealing, low heat lose.

2. Excellent chain grate

The grate is 500~1000mm longer than others, the fuel combustion time is longer, improve the combustion efficiency. The small scale flake grate could resist the temperature as high as 1200℃, long working life.The chain grate has a low coal leakage because of the small gap.
Membrane water wall
Sufficient output

3. Sufficient output

The boiler is equipped with double drums, membrane water wall, and large diameter furnace, the radiant heating area increases more than 50%, achieves sufficient output.

4. Both sides air inlets

Boiler adopts bilateral air inlets and independent wind chambers, could adjust wind volume and pressure flexible, to ensure the sufficient combustion.
