The corner tube boiler technology is a kind of high quality and high efficiency, energy saving and environmental protection product which introduced from Denmark by the former Shanghai Si Fang Boiler Works in 1985. Through the digestion and absorption of the introduced corner tube boiler technology, and continuous development for many years combining with China's national conditions (fuel and water quality), its product technology has been widely applied in the field of solid fuel boilers.

Summarizing the advantages and disadvantages of existing gas fired boiler technology, based on the combustion and heat transfer characteristics of gas fired boilers, and combined with the mature corner tube boiler technology, SIBRI has successfully developed a new type corner tube gas fired boiler technology.

1. Typical corner tube boiler self-supporting structure, the structure is mature and stable.

2. The boiler room is designed by single layer layout.

3. The vertical type (commonly used) or horizontal type can be arranged according to the user‘s site conditions.

4. The vertical furnace type is arranged by inverse "N" type, the boiler structure is similar with the traditional II boiler. The horizontal furnace is arranged by tunnel type.

5. The boiler body includes drum, water tube system, superheater, economizer, condenser (or air preheater) and so on.

6. Boiler heating surfaces are arranged flexibly, more suitable for the boiler with capacity of 40t/h above, and no upper limit for the boiler capacity.

7. The boiler body is designed by modules, can be fabricated in segments in the workshop. On site only little welding is to short erection, which more suitable for large capacity boilers.

8. The heating surface adopts 100% water pipe structure, which is suitable for high parameter boilers and no upper limit of working pressure.

9. Natural circulation, safe and reliable, high quality of steam.

10. The structure of the boiler heating surface is simple, and convenient manufacturing, maintain and repairing.

11. The boiler body adopts the structure of membrane wall with good sealing performance.

12. Light furnace wall structure, and rapid start and stop for the boiler. 

13. Less steel consumption, compact structure, light overall load, and low cost of civil engineering.
