Revolutionary device could make gas furnaces safer and greener

Even the cleanest gas furnaces could become even more efficient and safer with a relatively inexpensive, easy-to-operate device. This raises the question: could it serve as an attractive alternative to the widely used heat pumps?

Despite gas furnaces and condensing boilers being categorized as low-emission units, it's crucial to remember that they still emit hazardous substances. Researchers from the Oak Ridge National Laboratory (ORNL) in Tennessee are tackling this issue head-on. They've shared insights in the Chemical Engineering Journal about a newly designed device that significantly reduces pollution from gas furnaces, highlighting its potential affordability.

How Does AGR Technology Work?

The AGR (acidic gas reduction) technology, devised by the ORNL team, can eliminate over 99.9% of harmful gases, such as nitrogen oxides, carbon monoxide, methane, and various hydrocarbons. Suitable for both industrial and residential heating systems, including gas furnaces and water heaters, this device can be integrated into both new and existing models.
Testing over 400 hours on a standard condensing furnace confirmed the AGR technology's capability to remove more than 99.9% of detrimental gases without any adverse consequences.

AGR System: effective, affordable, and virtually maintenance-free

The device produces condensate with a neutral pH level, removing the need for corrosion-resistant materials in its production and lowering costs. The researchers believe that adopting this technology will bolster environmental sustainability and allow for the sale of more efficient heating units.

The ORNL team has stressed that the AGR technology requires minimal user intervention. Systems equipped with AGR only need maintenance every three years. Like replacing gas cylinders, the spent AGR unit can be easily swapped out for a new one by the user or a professional.
