Field Assemble Chain Grate Coal Fired Steam Boiler

SHL series new type field assemble chain grate boiler is developed by Zhengzhou Boiler, which adopted the latest combustion theory product of Xian Jiaotong University. This is the fourth generation of chain grate boiler. It has features of high output, high combustion efficiency, stable operation, wide range of overload adjustment, can be adjusted to many kinds of coals, energy saving, environment-friendly and so on. 1. It adopts widthwise layout double drums structure, which totally overcomes the phenomenon of bulge by directly heating the drum in the furnace. The layout of the heating surface is more reasonable. 2. The two sides of furnace adopt membrane water structure which can ensure the seal ability of the furnace and higher the boiler efficiency as well. 3. In the heating surface of the boiler convection bank and the economizer, there are junctions of dust blower reserved. To some special material(especially the strong caking fuel), necessary measures can be adopted, to avoid the corresponding problems. 4. It adopts the latest arch research production of Xian Jiaotong University, downside αtype arch technology, the fuel combustibility is improved and it can adjusted itself to many kinds of coal. 5. The arch adopts water cool structure, which can improve both the rigidity and the reliability of the arch, and the service life is extended. 6. It adopts GEFs improved appropriative slag removal technology. The grate adopts new type small flake type, in addition, the unique safety ring is adopted, all these add up, totally overcome the problem of the grate flakes falling of, and reduce the air leak efficiency, so that the grate can be operated stably and the combustion efficiency is greatly improved. 7. The grate adopts double sides wind feeding, separate air chambers, which can meet the requirements of the combustion of the fuel efficiency. 8. It adopts two times wind feeding structure, the aerodynamic field in the furnace is improved effectively. The heated particles of the fuel are threw to the front arch, which is propitious to the ignition of the fuel, at the same time, the fuel is kept in the furnace in a longer time, so that the adjustment and the utilization rate of the fuel is improved. 9. The boiler grate adopts double layers or single layout structure, which can meet the customers requirements better.
