Project introduction

The overhaul life of the patented combined furnace lining of the power generation boiler invented by Luohua Company is more than 10 years, and it is rarely repaired during operation. In 1995, Yueguangxi academician of Tsinghua University and experts from the Institute of Thermal Energy of the Chinese Academy of Sciences came to our unit to appraise the achievements. In 2001, "Research on non-metallic new hanging structure composite furnace wall structure and new material application at the top of circulating fluidized bed boiler"; "Domestic research and application of imported large circulating fluidized bed (CFB) and intermediate reheat natural circulation boiler lining" was appraised by China Nonferrous Metals Industry Association in 2007, and "Research on non-metallic new hanging structure, composite furnace wall structure and new material application at the top of circulating fluidized bed boiler" won the third prize of Luoyang Municipal Government Science and Technology Progress Award.

　　The project has obtained the patent number of Anti-wear Structure at the Bottom of the Furnace Hole of Circulating Fluidized Bed Boiler (200720091848.5), the patent number of Anti-wear Structure at the Coal Drop Tube of Circulating Fluidized Bed Boiler (200720091849. X), the patent number of Anti-wear Structure Design at the Boundary of Boiler Lining (200710055138.1), and the patent number of Localized Lining Structure of Large Circulating Fluidized Bed Boiler (200710055139.6) The patent number 01262211.7, the patent number 01262212.5, and the patent number 01262212.5 of the new non-metallic hanging furnace lining structure at the top of the circulating fluidized bed boiler.
