ANNEALING FURNACES RECUPERATIVE BURNERS

MASSACHUSETTS

CHALLENGE

B2Q was retained to complete an investment grade study and design services at an old industrial manufacturing building for replacing an outdated annealing furnace, plagued with operational challenges, with a high-efficiency natural gas furnace.

OPPORTUNITY

B2Q led the design of the high-temperature, corrosion-resistant exhaust system for the new 4,500 CFH natural gas annealing furnace with 18 recuperative burners. Several challenges were overcome including physical space constraints and a small installation window. In 9 weeks, B2Q finished the design and bid out the exhaust system, including mechanical, electrical, and controls. B2Q was involved throughout commissioning to ensure seamless integration and was retained during furnace installation to re-design the manufacturer-provided gas train to meet code requirements.

RESULT

The furnace replacement allowed our Client to expand their product offering by providing the ability to manufacture a new product not previously possible as well as reduce electricity consumption by more than 1M kWh. The project qualified and obtained a utility incentive of more than $450,000 and had a return on investment of approximately 15% based on energy savings alone.

The ETIC RCx project was an outstanding success, delivering verified energy savings and operational improvements that exceeded UMass Lowell’s expectations. The project achieved impressive annual cost savings—10% higher than initially projected—while reducing energy intensity by 14% for UMass Lowell’s third-largest utility account.

Beyond cost savings, the initiative delivered significant environmental benefits, cutting annual carbon emissions by 530,000 lbCO2e. Additionally, it enhanced lab safety through robust lab pressurization tracking and the recalibration of all terminal devices.

This success was made possible through the unwavering collaboration between UMass Lowell, B2Q, and NGRID, demonstrating the power of partnership and a shared commitment to cost efficiency, sustainability, and operational excellence.
