Buildings - Capturing furnace emissions - Technology Org:
Oak Ridge National Laboratory researchers have developed a novel solution to reduce the environmental impact of natural gas-condensing furnaces commonly used in U.S. homes. The team built a prototype furnace that incorporates monolithic acidic gas reduction, or AGR, as the catalyst to minimize acidic gases and condensate acidity, and oxidize carbon monoxide, hydrocarbons and methane.
In a demonstration, researchers conducted a 400-hour reliability and durability test and proved that AGR, made of titanium dioxide, copper oxide and minor platinum, removed more than 99.9% of the acidic gas products produced during combustion. It trapped and removed sulfur oxides and reduced additional emissions.
[...] ORNL's Zhiming Gao said [...] "This technology could be applied to commercial rooftop units, thermally driven heat pumps, gas-fired water heaters and boilers."
