Tongliao Thermal Power Station

Project Overview: Tongliao Thermal Power Station

Project Name: Tongliao Thermal Power Station City Heating System
Location: Tongliao, Inner Mongolia, China
Industry: Thermal Power Generation and District Heating
Main Function: City Heating

Project Details:

The Tongliao Thermal Power Station, located in Inner Mongolia, plays a key role in the region's energy infrastructure. It generates power and provides district heating to the city, which is essential for ensuring the well-being of its residents, particularly during the harsh winters. To improve the station’s heating efficiency and expand its capacity, the facility is adopting a new absorption heat pump system.

Objective:

The goal of this project is to enhance the heating efficiency by incorporating LiBr (Lithium Bromide) absorption heat pumps, enabling more effective use of the energy generated and improving the overall heating capacity. The system is designed to serve the city heating needs of Tongliao and its surrounding areas, especially during the winter season.

System Components:

1. LiBr Absorption Heat Pumps:
   • These heat pumps are used to recover waste heat from the station’s operations and boost heating efficiency.
   • LiBr absorption heat pumps are ideal for district heating systems as they utilize thermal energy (such as waste heat) rather than electrical energy to provide cooling or heating.
   • The heat pumps are powered by waste heat, further improving energy utilization and reducing operational costs.
2. Equipment Selection:
   • 1 unit of 9MW LiBr absorption heat pump: Provides a large capacity for citywide heating demands.
   • 1 unit of 7MW LiBr absorption heat pump: Supports the 9MW unit, allowing for flexibility and increased reliability.
   • 1 unit of 12MW LiBr absorption heat pump: This high-capacity unit will significantly enhance the overall heating output of the system.
   • 1 unit of 3.5MW LiBr absorption heat pump: A smaller unit to support the operation and ensure a balance in heat distribution across the system.

Main Function:

• City Heating: The primary function of this system is to supply heating to the city of Tongliao, providing warmth to residential, commercial, and public buildings during the colder months. This district heating project is particularly important for Inner Mongolia, where winters can be extremely harsh.
• The LiBr absorption heat pumps will recycle waste heat generated during power generation, making the process more efficient and reducing the need for additional fuel consumption.

Benefits of the System:

• Improved Heating Efficiency: By using absorption heat pumps, the project reduces the need for additional energy input to generate heat. Waste heat is utilized effectively, which improves the overall efficiency of the thermal power station.
• Energy Savings: These heat pumps are more energy-efficient than traditional electric heating systems, allowing the Tongliao Thermal Power Station to reduce energy consumption and operational costs.
• Sustainability: The integration of LiBr absorption heat pumps allows for sustainable energy utilization, as it reduces the environmental impact by utilizing waste heat instead of relying solely on fossil fuels.
• Increased Heating Capacity: The system provides a significant boost to the heating capacity of the thermal power station, ensuring that Tongliao can meet its increasing energy demand during peak heating seasons.

Long-term Impact:

This project supports Tongliao’s efforts to become more energy-efficient while addressing the heating demands of the city, especially during long, cold winters. It also contributes to China’s overall energy sustainability goals, particularly in Inner Mongolia, where energy needs for heating are substantial. The project is a step toward more environmentally-friendly energy systems and efficient use of waste heat, which could serve as a model for other cities in similar climates.
