1. The boiler adopts a wet back three return structure, and the smoke pipes are symmetrically arranged and evenly distributed, which can improve the stress distribution of the tube sheet. The wet back structure combustion chamber is completely immersed in water, with good cooling conditions. The rear tube plate is not washed by high temperature flue gas, and has a long service life.

2. The application of corrugated furnace liner not only increases the heating surface, but also alleviates the possible damage of thermal expansion and contraction to the combustion chamber, and improves the strength.

3. The front and rear smoke boxes are hinged for easy opening and maintenance.

4. The large steam space makes the speed of steam leaving the water surface low, and the built-in steam water separation device ensures stable steam output.

5. The threaded smoke pipe is used to enhance the heat transfer effect and improve the thermal efficiency.

6. The applied digital control technology can remotely control the combustion process. High degree of automation, complete protection and automatic control of water level and pressure.

7. Condensation heat exchanger made of special materials can be added at the smoke outlet to reduce the smoke exhaust temperature and collect the sensible and latent heat in the smoke, and improve the efficiency of the boiler (up to 95%).
