The winner of this year’s VESTA Green Product Award, the Earth’s Flame fireplace grate makes conventional fireplaces much cleaner. Designed to fit into existing masonry and zero clearance fireplaces, Earth’s Flame uses an angled refractory panel and pre-heated secondary combustion air to achieve up to 72% reductions in particulate emissions from fireplaces. The award was given based on emissions, and doesn't imply that fireplaces with the Earth's Flame grate are any better at heating a home than conventional fireplaces.
The refractory plate is held above the combustion zone of a traditional fireplace, keeping combustion gases and particulate matter in the hottest zone longer for more complete combustion of potentially harmful pollutants. The plate also increases the turbulence of combustion gases, mixing them more completely with pre-heated air and burning the suspended particulates more completely before gas leaves to the chimney. The resulting fire’s emissions are 33% below EPA Phase 2 voluntary standards for a 36” zero clearance fireplace. The grate is not yet available for purchase, but if you are interested, you can sign up at the producer’s website to be notified when it enters the market.
