Decarbonization and cost reduction in industrial heating systems with electric hot oil heaters
The adoption of electric thermal oil heaters has seen significant growth in recent years, aligning with the global trend of electrification and decarbonization across various industrial processes. Installing an electric hot oil boiler enables the decarbonization of heating systems that previously relied on thermal fluid technology.
This shift is primarily driven by economic and environmental benefits:
1. Electric boilers typically offer lower operational costs due to reduced maintenance requirements and the absence of hazardous fuel handling and storage. Moreover, when electricity prices are lower than natural gas, these cost savings become even more substantial.
2. Replacing combustion-based thermal fluid heaters with electric hot oil boilers helps reduce carbon emissions. Fossil fuel-powered boilers emit COâ‚‚ and other pollutants, while electric alternatives avoid direct emissions during the heating process.
However, the extent of decarbonization depends on the energy source used for the electric boilers. If the electricity comes from renewable sources, the environmental impact is significantly reduced. Conversely, if the grid still relies heavily on fossil fuels, the emission reduction will be less pronounced.
Combustion heaters may still be maintained in certain situations, such as:
- As a backup to the electric boiler.
- To support operations during peak production times.
- When energy cost analysis indicates it is more economical.
**Additional Advantages of Transitioning to Electric Hot Oil Boilers**
Beyond the economic and environmental benefits, electric thermal fluid boilers provide several other advantages:
- Electric heaters are more efficient, requiring less energy to produce the same amount of heat, thus reducing energy consumption and emissions.
- They eliminate the release of pollutants like nitrogen oxides, particulates, and volatile organic compounds, which are common with combustion boilers.
- These systems occupy less space and offer greater flexibility in installation since they do not require fuel storage infrastructure.
- Electric boilers often come with advanced control and automation features, enabling precise temperature regulation and improved efficiency.
- Adopting electric boilers can help companies comply with environmental regulations and avoid potential fines or penalties.
**Key Considerations Before Replacement**
Before replacing a combustion thermal fluid boiler with an electric one, several factors should be carefully evaluated to ensure optimal performance and efficiency:
- Confirm that the new heater can reliably meet the required heat demand and capacity.
- Ensure the electric boiler provides comparable or better energy-to-heat conversion efficiency.
- Analyze both investment and operational costs, including electricity rates and maintenance expenses.
- Evaluate the availability and sustainability of energy sources, especially when aiming for decarbonization.
- Check if the existing electrical infrastructure can handle the additional load without major upgrades.
- Understand the regulatory requirements for installing and operating electric boilers.
- Assess how the new system will integrate with current heating processes and whether it affects production capacity.
- Conduct a life cycle analysis to compare the environmental impact of both options throughout their entire lifespan.
A comprehensive evaluation of these factors will help determine the best solution for the company's operational, financial, and environmental goals. It’s essential to work with experienced engineers and consultants who specialize in industrial energy systems to ensure a smooth transition.
**Hybrid Systems with Parallel Heaters**
Hybrid or parallel systems use both combustion and electric boilers simultaneously, allowing companies to leverage the strengths of each. This setup enhances efficiency, flexibility, and reliability in industrial heating systems.
Before implementing a hybrid system, a detailed engineering analysis is necessary. This includes evaluating the compatibility of existing equipment, assessing the electrical infrastructure, comparing operating costs, and ensuring the system meets efficiency and decarbonization targets. Proper design and planning are crucial to achieving optimal performance.
Reasons for choosing a hybrid system include:
- Cost optimization by selecting the most economical energy source at any given time.
- Enhanced system capacity to meet fluctuating heat demands.
- Greater operational flexibility, allowing both boilers to run together during high-demand periods.
- Improved decarbonization efforts by prioritizing cleaner energy sources when available.
- Increased reliability through redundancy, reducing the risk of production downtime.
Effective control and automation systems are vital to ensure seamless coordination between the two types of boilers.
**Smart Hybrid System**
Pirobloc’s R&D team is developing a smart hybrid system capable of accessing real-time data on gas and electricity prices. The system automatically selects the most cost-effective and environmentally friendly energy source, enhancing both efficiency and sustainability.
Benefits of this intelligent approach include:
- Cost savings by using the cheapest available energy source.
- Improved energy efficiency through optimized resource utilization.
- Flexibility to adapt to changing energy prices and demand patterns.
- Greater decarbonization potential when powered by renewable energy.
- Automation reduces the need for manual decision-making.
- Reduced emissions by favoring cleaner energy sources.
**Case Study 1: Replacing a Thermal Oil Boiler with Two Electric Boilers**
A client sought to replace two 1,500,000 kcal/h fuel oil thermal oil boilers with two electric units. The goal was to switch from a 10-hour daily operation to continuous 24/7 operation to maintain stable temperatures for asphalt tar storage.
Key considerations included maintaining flow rates, optimizing pressure loss, and calculating the required power to sustain the desired temperature. After analysis, two 600 kW electric boilers were recommended, along with a diesel backup boiler to support the transition.
**Case Study 2: Hybrid Installation with a Thermal Oil Heater and an Electric Heater**
In another case, a client explored combining a natural gas-fired thermal oil heater with an electric unit. The objective was to alternate between the two based on fuel price fluctuations.
Pirobloc proposed a 700 kW electric boiler to match the existing capacity. The project involved upgrading the pump system, expanding the expansion tank, and integrating a control panel to manage both systems efficiently.
By analyzing energy usage, flow rates, and system compatibility, Pirobloc provided a tailored solution that balanced cost, efficiency, and environmental impact.
