wns gas fired steam boiler, and the other is gas fired hot water boiler.
1. The capacity of gas fired steam boiler is 1~10t/h, working pressure is 0.7~1.6MPa.
2. Output of the hot water boiler is 0.7~7MW, water service temperature is 95degree or 115degree, water return temperature is 70degree.
3. The grate shall employ the technology patent of small roller structure, boundary grate and so on, improving the operation reliability of the boiler.
4. The combustion chamber consists of corrugated internal furnace and wet smoke box.
5. The fuel oil is atomized and injected from the burner into the combustion chamber where it's burnt into smoke of high temperature.
6. The smoke enters the second pass threaded smoke tubes after the radiation and the convection heat transfer occurred in the furnace and the smoke box, then it's back to the third pass smoke tubes, and proceeds with the convection heat transfer again.
