Denmark SONDERBORG Thermal Power Plant Project
The SONSERBORG Power Plant in Denmark utilizes large-scale LiBr Absorption Heat Pumps as part of its district heating system. Here’s a breakdown of the equipment and its main function:
Equipment Selection:
- 1 unit of 2.8MW LiBr Absorption Heat Pump
- 1 unit of 5.0MW LiBr Absorption Heat Pump
- 1 unit of 11.2MW LiBr Absorption Heat Pump
- 1 unit of 16MW LiBr Absorption Heat Pump
Main Function:
- District Heating: These heat pumps are designed to generate heating for a district-wide network. The system provides heat to residential and commercial buildings within the area, using the absorption heat pumps to recover waste heat from various sources (such as industrial processes or natural gas) and convert it into useful thermal energy. This process helps reduce energy consumption and lowers the carbon footprint by utilizing renewable or waste heat sources.
Key Features:
- Large Scale Heat Pumps: The units range in size from 2.8MW to 16MW, making them suitable for district heating, which requires a high thermal output.
- Absorption Heat Pump Technology: The LiBr absorption heat pumps work by using a heat source (often waste heat or renewable energy) to drive the refrigeration cycle, which then produces hot water for heating purposes.
By integrating multiple absorption heat pumps of different capacities, the SONSERBORG Power Plant is able to provide efficient, scalable district heating to a large area while also minimizing energy consumption.
General introduction
Denmark, as one of Europe's industrial powerhouses, has indeed focused on sustainability and energy efficiency, making significant strides toward reducing reliance on fossil fuels. Despite having limited natural resources, the country has prioritized innovation in energy saving, with goals such as becoming "fossil fuel independent." Over the past three decades, Denmark's economy has seen substantial growth, with energy consumption staying nearly constant, showcasing the effectiveness of their energy-saving initiatives.
In this context, Hope Deepblue has made a substantial contribution to Denmark's energy efficiency goals by supplying the SONSERBORG Power Plant with four units of hot water-fired absorption heat pumps, each with different heating capacities:
Equipment Supplied:
- 1 unit of 2.8MW hot water absorption heat pump
- 1 unit of 5.0MW hot water absorption heat pump
- 1 unit of 11.2MW hot water absorption heat pump
- 1 unit of 16MW hot water absorption heat pump
Total Heating Capacity:
- 35MW (from the combined capacity of the four heat pumps)
Purpose:
- These heat pumps are designed to efficiently generate district heating. The district heating system uses waste or renewable heat sources to supply thermal energy to residential, commercial, and industrial buildings, contributing to reducing the need for fossil fuels.
Key Features of the System:
- Energy Efficiency: The absorption heat pumps utilize available heat sources (often waste heat or low-grade heat) to produce hot water for heating, allowing Denmark to optimize energy usage and minimize environmental impact.
- Large-Scale Heating Solution: With a total heating capacity of 35MW, these heat pumps provide a significant amount of thermal energy, supporting the district heating system for a large area.
- Support for Denmark's Sustainability Goals: By integrating these heat pumps, Denmark can reduce its reliance on imported fossil fuels and meet its ambitious energy efficiency and sustainability targets.
Hope Deepblue's contribution to this project aligns perfectly with Denmark’s energy strategy, helping maintain economic growth while ensuring energy conservation and reduced carbon emissions.
The central heating system you've described integrates geothermal energy heat pumps with heat recovery from both boiler exhaust and geothermal resources, leveraging multi-stage processes to maximize energy efficiency. This approach makes the most of the available heat sources and allows for precise control over temperatures and flow rates to optimize the absorption heat pump's performance.
Here's a breakdown of the key components and features of this specialized system:
Key Features:
- Geothermal Energy and Heat Recovery:
- The system utilizes 47°C low-temperature geothermal energy as one of the primary heat sources. This is a sustainable and renewable source of energy, which is typically abundant in geothermal-rich regions.
- It also uses high-temperature hot water produced by burning timber and household waste. This aligns with the goal of waste-to-energy and renewable energy integration, reducing reliance on traditional fossil fuels.
- Exhaust Heat Recovery: The system recovers heat from the exhaust gases discharged by the boiler, using it to preheat water or support the district heating network, contributing to the overall energy efficiency.
- Multistage Heat Recovery:
- The exhaust gases go through a multistage wet scrubbing system, which removes dust and particulates before the heat is fully recovered. This ensures both environmental and system efficiency by preventing contamination of the heat recovery system.
- By recovering exhaust heat at multiple stages, the system maximizes the usable heat and reduces waste, making it more energy-efficient.
- Precise Temperature Control:
- Temperature control is highly precise, with each part of the system needing to maintain temperatures within a 0.1°C range. This ensures that the geothermal and waste heat are utilized as efficiently as possible, preventing energy loss and maximizing system performance.
- Temperature and flow rate are regulated separately to ensure optimal heat utilization and to adjust for varying heating demands, which can improve the overall absorption heat pump efficiency.
- Absorption Heat Pump:
- The system utilizes an absorption heat pump, where heat is absorbed from the geothermal and exhaust heat sources and transferred to the heating system. The absorption cycle typically uses lithium bromide (LiBr) or ammonia as the absorbent, efficiently converting waste or low-grade heat into usable thermal energy.
- The special structure of the heat pump system is evident, where the absorber and condenser are separately controlled, allowing them to output hot water at different temperatures for various uses, such as district heating or industrial processes.
- Complicated Flow Chart and Control Mode:
- The flow chart of the absorption heat pump system is complex due to the integration of multiple heat sources and the need for precise control of the temperature, flow rates, and heat recovery processes. This requires advanced control systems to manage the heat flow, temperature regulation, and integration of the various energy sources.
- The control mode ensures that all components of the system operate efficiently in unison, adjusting for fluctuations in heating demand and available heat sources.
Benefits of the System:
- Energy Efficiency: By combining geothermal energy with heat recovery from boiler exhaust, this system significantly reduces the need for external energy inputs, leading to lower operational costs and reduced environmental impact.
- Sustainability: The use of renewable geothermal energy and the conversion of waste materials into heat aligns with sustainability goals, reducing the reliance on fossil fuels.
- Reduced Emissions: The wet scrubbing system helps clean exhaust gases, minimizing particulate emissions, and contributing to better air quality.
- Optimized Heat Utilization: The precise temperature and flow control ensures that all available heat is efficiently utilized, preventing energy waste and maximizing the effectiveness of the absorption heat pump.
Overall System Performance:
This sophisticated system combines several energy sources, including geothermal, biomass, and waste heat, with advanced temperature control to optimize the efficiency of the absorption heat pump, enabling highly efficient district heating and process cooling applications.
