Recently, the 330,000-kilowatt unit inverted vertical and three-stage heat transfer U-tube high-pressure heater designed and developed by Harbin Boiler Factory Co., Ltd. successfully passed the 168-hour trial operation at Huaneng Xinhua Power Plant Unit 6. Prior to this, the first 330,000 kW Huaneng Huaiyin Power Plant Phase II, No. 3 and No. 4 units, inverted vertical and three-stage heat transfer U-tube high-pressure heaters were developed in October 2004 and February 2005. Successfully, the high-pressure heaters of No. 3 and No. 4 machines have been running smoothly for more than half a year. At present, all performance indicators have reached the design value, and the equipment runs smoothly. This marked the success of the 330,000-kilowatt inverted U-tube high-pressure heater designed and developed by Haguo.
In the development of large-capacity thermal power units in China, horizontal U-tube high-pressure heaters have a dominant position, but vertical U-tube high-pressure heaters also occupy a considerable share in the electricity market. Before August 2003, in the domestic large-scale unit 300,000 kW class high-pressure heater market, only one enterprise in China had the ability to produce such inverted vertical high-pressure heaters, and the rest were imported products. In order to improve the technical capacity and level of its own high-pressure heaters, and to break the market situation of monopolizing vertical high-pressure heaters with a monopoly of 300,000 kilowatts, Haguo decided to make a breakthrough here.
The design features and structure of the inverted vertical high-pressure heater are quite different from those of the horizontal high-pressure heater. Its structure is complex, and it is quite difficult to design and manufacture. In this regard, Harbin took the approach of "based on self-development, absorbing advanced technology, going out, please come in", through research and research, combined with the technical characteristics of Toshiba and Alstom, developed the company with 33 million kilowatts of units upside down High pressure heater products. After running the test, it proved that the product has excellent performance and achieved satisfactory results. At present, the 330,000-kilowatt inverted vertical high-pressure heater has already ordered 10 sets, which fills the blank of the inverted U-tube high-pressure heater of the large-capacity unit.
