China Energy Investment Corporation's Ningxia Liupanshan Power Plant 1-million-kilowatt unit put into operation

en.Wedoany.com Reported - At 10:56 on October 30, Unit 1 of the Liupanshan Power Plant of China Energy Ningxia Electric Power under China Energy Investment Corporation in Guyuan City, Ningxia, China, passed a 168-hour full-load trial operation and was officially put into commercial operation. With an installed capacity of 1 million kilowatts and core power generation equipment supplied by Dongfang Electric Corporation, the unit is the first unit to be put into operation under a typical demonstration project featuring the "two joint operations" of coal power with coal and coal power with new energy at the 1-million-kilowatt level in China.

The Liupanshan Power Plant is planned for the overall construction of two 1-million-kilowatt high-efficiency ultra-supercritical indirect air-cooled coal-fired power generation units, complete with desulfurization and denitrification facilities and a dedicated railway line, and new energy projects configured at a ratio of coal power installed capacity to new energy installed capacity of 1:2. The supporting coal project includes the Nanwan Coal Mine with an approved annual production capacity of 4 million tonnes.

Unit 1 adopts a new-generation high-efficiency ultra-supercritical flexible power generation technology, applies full-range adaptive intelligent cruise control technology across the 20%–100% load range, and is equipped with a new high-efficiency plasma ignition system suitable for high-moisture, low-calorific-value coal types. The plant site has completed a 1-million-kilowatt-class single-shell hyperbolic steel structure indirect air-cooling tower and a single-row frame–combined side coal bunker structure, and adopts ultra-high building safety intelligent monitoring technology integrating laser and BeiDou.

Dongfang Electric Corporation is responsible for the supply of the unit's main power generation equipment. Dongfang Electric Machinery supplied the 1000 MW turbine generator, featuring flexible stator support, elastic rotor winding support, and a split-type inner and outer stator transport structure; Dongfang Turbine supplied the 1000 MW steam turbine, equipped with a new-generation high-efficiency wide-load blade profile and capable of industrial steam extraction and heating steam extraction; Dongfang Boiler supplied the high-efficiency ultra-supercritical single-reheat boiler, applying an intelligent sootblowing system and a combined side coal bunker steel frame design.

The power plant adopts a water resource cascade utilization system, equipped with a "low-temperature concentration + high-temperature drying" wastewater treatment process, using the compliant tailwater from Guyuan City's urban sewage treatment plants as the main production water source, with a designed annual consumption of 4.1 million cubic meters of reclaimed water. Nearly 8,000 concrete pile heads generated during construction were crushed and reused for site hardening and railway access road paving.

The project's dedicated railway line connects to the logistics system of the Guyuan New Materials Industrial Park. The power plant is also equipped with industrial steam supply and centralized heating facilities, and undertakes peak-shaving and power supply tasks for the southern Ningxia power grid.
