If you plan to invest in a robust used power plant for industrial power supply, this second-hand thermal plant package containing two 150MW thermal power units delivers a complete coal-fired power plant solution built around high-quality steam turbine assembly, turbo generator, cogeneration unit and condensing turbine. Every steam turbine within this used power plant package has accumulated years of stable onsite operation, so this condensing turbine and cogeneration unit can deliver consistent and dependable power output for long-term industrial projects. Commissioned in 2007, the whole coal-fired CHP plant is optimized to burn coal gangue and low calorific value coal to control fuel operating costs, with each thermal power unit fitted with a heavy-duty coal gangue boiler to sustain stable combustion of low-grade fuel.

1. Specifications
1.1 Unit configuration: This second-hand thermal plant includes two 150MW thermal power units. Unit 1 is designed as an extraction condensing cogeneration unit, equipped with a C150 extraction condensing turbine paired with a QFJ-150-2 turbo generator. Unit 4 adopts pure condensing configuration, using an N150 pure condensing turbine matched with a QF-150-2 generator. All steam turbines run at 3000rpm, 50Hz, adopting single shaft turbine, double cylinder turbine and double exhaust design. Each thermal power unit is built as a full power generator set that combines steam turbine and turbo generator for synchronized power production.
1.2 Boiler parameters: Each thermal power unit installs the Wuxi Huaguang UG-480/13.7-M coal gangue boiler. This 480t/h ultra-high pressure boiler with single reheat circuit operates at 13.7MPa and 540℃. The reheat boiler generates superheated steam and feeds superheated steam directly into the steam turbine for power generation inside the closed-loop steam cycle and steam cycle system.
1.3 Auxiliary system: Reserved auxiliary ports connect to cooling water system, feedwater treatment system and flue gas treatment system to form a complete power station auxiliary system that supports stable running of the whole power generator set and every thermal power unit. These auxiliary pipelines are pre-reserved for seamless connection of all auxiliary equipment.
1.4 Technical support: We supply original engineering drawings, factory test reports and full technical documentation to support turbine overhaul, power plant dismantling, site inspection, power plant refurbishment and reinstallation of the steam turbine, condensing turbine, cogeneration unit and turbo generator.
1.5 Operation modes: This steam turbine package supports dual working modes. The cogeneration unit generates electricity while offering continuous industrial steam supply for production processes; the pure condensing turbine maximizes electric output as a dedicated power generation unit. A steam extraction unit can be configured additionally on the basis of this steam turbine structure if process heat supply is required.
2. Advantages
2.1 Proven stable performance: The steam turbine assembly, coal gangue boiler and turbo generator have long-term stable operation records, suitable for uninterrupted base load generation for large industrial zones. As a valuable pre-owned power asset, this used power plant maintains steady performance under continuous load for both cogeneration unit and pure condensing turbine.
2.2 Low fuel cost: This coal-fired CHP plant is compatible with coal gangue and low calorific value coal, greatly cutting fuel expenditure compared with a brand-new coal-fired power plant. The specially designed coal gangue boiler ensures high combustion efficiency of cheap low-grade fuel.
2.3 Flexible application scenarios: This thermal power unit fits utility power supply, factory self-consumption and backup grid-connected power plant scenarios. The cogeneration unit can satisfy both power and heat demand for industrial parks, while the condensing turbine focuses on maximizing power output.
2.4 Competitive capital budget: This used power plant requires far lower investment than constructing a new coal-fired power plant. After power plant refurbishment and plant commissioning, the complete thermal power unit can be put into operation quickly.
2.5 Simple maintenance and service: Globally available spare parts cover the steam turbine, turbo generator, coal gangue boiler and all auxiliary equipment, making daily maintenance and turbine overhaul straightforward for operators.
2.6 Mature integrated system: The complete power generator set integrates boiler island, steam turbine and turbo generator into a reliable closed-loop steam cycle system. It adopts mature steam turbine technology, making this second-hand thermal plant a cost-effective used power plant solution for global energy investors looking for a ready-to-deploy thermal power unit and cogeneration unit.
