According to reports, during the trial operation, the overall operation of the unit was very stable, the maximum load reached 224,000 kilowatts, and the main technical performance indicators of the boiler met the design requirements. In particular, the self-developed external heat exchanger, the compact split-flow ash heat exchanger, has stable and reliable operation performance and has withstood the test of operation practice.
In order to develop a domestically produced 200,000 kW class circulating fluidized bed boiler, Xi'an Thermal Power Research Institute independently developed an external heat exchanger - a compact split ash return heat exchanger. The external heat exchanger adopts a unique pneumatic method to control the circulating ash split flow, and integrates the return hot valve and the external bed of the circulating hot ash, and has the characteristics of simple structure, convenient operation and maintenance, saving investment, etc., and is circulating fluidized. The large-scale development of bed boilers has opened up a new way.
The circulating fluidized bed boiler technology is the same as the flue gas purification treatment technology, supercritical and ultra-supercritical unit power generation technology, etc. It is one of the clean coal power generation technologies, which has a significant reduction in pollutant emissions, wide adaptability of coal types, and good load-changing performance. specialty.
I made my first 210,000 kilowatt circulating fluidized bed (CFB) boiler.
On July 14th, it was learned from Huaneng Group that on July 7, Huaneng Holding Xi'an Thermal Power Research Institute developed and designed the first domestically produced 210,000 kilowatt circulating fluidized bed (CFB) boiler unit to pass the 96-hour trial run. This marks the successful development and application of the first large-capacity circulating fluidized bed boiler with complete independent intellectual property rights in China.
