Revolutionary Device Enhances Home Furnace Safety and Durability at Low Cost.

Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed an affordable add-on technology that removes more than 99.9% of acidic gases and other emissions to produce an ultraclean natural gas furnace. This acidic gas reduction, or AGR, technology can also be added to other natural gas-driven equipment such as water heaters, commercial boilers, and industrial furnaces. The AGR technology would allow furnace manufacturers to use materials that are more affordable than the stainless steels used in most heat exchangers, which could increase affordability and allow furnace manufacturers to sell more high-efficiency furnaces that meet California’s proposed new standards for residential and commercial furnace emissions.
