Linqu Western Thermal Power Station Project
Steam LiBr Absorption Heat Pump
The project located in Linqu, Shandong, involves the installation of a 31.33MW steam-fired LiBr absorption heat pump. This system will primarily be used for exhaust heat recovery, where waste heat generated from industrial processes or energy production is captured and converted into useful thermal energy. The heat pump will then be utilized for district heating, supplying heat to residential, commercial, and industrial areas within the surrounding district. The integration of the heat pump ensures more efficient use of available energy by recovering waste heat and redistributing it for heating purposes, contributing to a more sustainable and energy-efficient heating solution for the region.
General introduction
The Linqu Thermal Power Station, which operates with three back-pressure coal-fired steam boilers, generates 450,000 m³ of exhaust gas per hour. To improve energy efficiency and reduce waste, Hope Deepblue partnered with Yurunfeng Technology Company to implement an exhaust waste heat recovery system at the station. This system, which includes a LiBr absorption heat pump, a spray tower, and other supporting components, is designed to recover and repurpose the waste heat from the exhaust gases.
The system is expected to recover approximately 130,000 GJ of heat annually, offering significant economic and environmental benefits to both the power station and the surrounding district heating network. The project’s main component, the 31.3MW LiBr absorption heat pump, provides a reliable and efficient means of utilizing the recovered heat for district heating purposes. By leveraging this exhaust waste heat recovery system, the power station not only improves its energy efficiency but also contributes to the city's heating needs, further supporting sustainable energy practices in the region.
The system at Linqu Thermal Power Station is designed to recover exhaust heat from the wet desulfurization process of three 75-ton coal-fired steam boilers. By capturing heat from exhaust gases with a temperature difference of 20°C (ranging from 50°C to 30°C), the system is capable of recovering 130,000 GJ of waste heat annually during the heating season. This recovered heat is used to supply heating to an area of 500,000 m², significantly enhancing the station's energy efficiency and contributing to environmental protection.
This waste heat recovery system offers substantial economic benefits to the power plant and similar industrial enterprises like steel plants by enabling the reuse of otherwise wasted energy. It also plays a vital role in expanding the urban heating network, increasing the area covered by district heating, and improving the overall economic performance of heating supply enterprises. Through this innovative approach, the system provides a more sustainable energy solution while supporting the local economy and reducing environmental impact.
