In the colder winter months when demand for power is at its highest, many plants will ramp up production efforts and reallocate existing resources in an attempt to maximize production, achieve target loads, and avoid revenue loss.
If your plant utilizes both pulverized coal and natural gas as primary fuels, utilizing both fuels together in the same burner is an easy way to maximize production and reach higher-than-average load requirements.
However, a dual-fuel setup requires modifications, time, money, and support from top management - things most plants don’t have in excess, especially during winter. Furthermore, these operational adjustments are complicated - an improper setup can lead to unburnt fuel, poor airflow mix, and high probability of spin vane linkage lockups.
Even with a proper setup, dual-fuel systems often result in operational strains, higher emissions, and eventual burner damage, leading to more frequent needed repairs and an overworked crew. For many plant owners and managers, these complications make the hassle of facilitating two fuels outweigh the benefits.
On the other hand, plants with outdated and poorly-maintained single-fuel burners typically lead to high LOI and NOx numbers that can test your plant's current environmental and economical position, creating a seemingly no-win situation.
To manage these competing objectives and avoid repeated replacements or repairs, plants should have burner units that can effectively accommodate both coal and gas fuels within the same space. To help plants maximize efficiency through the simultaneous use of pulverized coal and natural gas fuels, Forney’s engineering team developed the Eagle Air II Coal/Gas Burner. This unit was specially designed to cycle through both fuels on varying load and supply conditions, ensuring the seamless use of both coal and gas in a single burner without being subjected to the stress and damage of most traditional dual-fuel setups.
Leveraging Forney’s years of combustion equipment design, we partnered with Storm Technologies, a company that specializes in large utility boiler performance optimization, to offer a powerful and convenient solution:
The Eagle Air II is a cost-effective option to seamlessly convert single-fuel systems to work with both pulverized coal and natural gas simultaneously.
Our Eagle Air II Burner has more effective coal flow into the burner throat which allows for better flame balance. It also has stronger flame anchor stability with close to 100% combustion resulting in lower LOI and NOx.
Our engineers have nearly a century’s worth of experience designing innovative combustion equipment. For the Eagle Air II burner, we combined this experience with the large utility boiler performance optimization expertise from Storm Technologies. This unique package created a solution that delivers the best steam power generation standards for quality and results.
One Eagle Air II can fire two fuels in one space which allows for maximum plant operation convenience and efficiency. This redundancy also provides plants with more flexibility in adjusting demand as needed due to fuel availability or demand.
With its dual fuel capability, the Eagle Air II Burner allows plants to more easily scale up or down to meet fluctuating demand. Plants can utilize existing resources without the need to retire coal plants or invest in entirely new solutions to improve performance metrics.
Additionally, Forney’s dual-fuel burner is more durable than alternative dual-fuel setups, providing for a long-lasting solution instead of a short-term patch.
Eagle Air II’s flue gas reheat system can save your plant from the expense of frequent burner repairs, tight maintenance schedules, burner modifications, wholesale replacement, and high LOI and NOx numbers.
Forney service engineers provide expertise and periodic maintenance capabilities to ensure reliable operation. With field offices and sales representatives around the world, Forney can easily provide reliable service with local product and application support to customers.
