The first domestic 2×1000MW secondary reheat ultra-supercritical π-type boiler units, made by Harbin Boiler Co., Ltd. under Harbin Electric Corporation (hereinafter referred to as “HBC”) for Datang International Leizhou Power Plant to follow the state policy of “using high-power units to replace low-power units”, were included in the list of the 1000MW-class gold medal units for reliability in the year of 2020 by the   the National Energy Administration. Such unit was the only one that won such honor in the 1000MW-class units. Before that event, in the Year 2020 Energy Efficiency Benchmarking Activity of Thermal Power Units in the Power Industry organized by China Electricity Council, our unit was successfully included in the list of 5A-class winner units of 1000MW class ultra-supercritical water-cooled units.

Such unit is the first domestic 1000MW-class secondary reheat ultra-supercritical π-type boiler unit manufactured by HBC. The most advanced secondary reheat technology was adopted. Its coal consumption for power generation was as low as 255.29g/kwh, the boiler efficiency at rated load being 95.1%, the nitrogen oxide emission at rated load being as low as 140mg/Nm³. Various parameters of the unit reached international leading level.

With the smooth commissioning of Datang International Leizhou units, HBC has become such an enterprise in this industry that can manufacture the ultra-supercritical secondary reheat boilers with the most complete furnace types and the best performance. HBC’s secondary reheat technology for thousands of MW class units has reached a higher level. With its advanced technical indexes and stability, the unit has successively won China Power Quality Engineering Award, the “Gold Unit” Award by China Southern Power Grid and some other awards one after another.
