ABSTRACT:
A high efficiency clean burning fireplace for burning solid fuels at pyrolytic temperatures is provided with refractory walls maintained about 1100.degree. Fahrenheit at different burning rates. A top wall of the combustion chamber includes an exhaust stack and a primary air heat exchanger having an exhaust manifold for discharging primary preheated combustion air down and across the inside surface of glass panels in the doors of the fireplace. A secondary air heat exchanger is mounted below the primary air heat exchanger and separated therefrom by a top refractory panel in the combustion chamber. The secondary air heat exchanger exhaust manifold is in the combustion chamber and discharges secondary combustion air across the top of the combustion chamber and into the primary combustion air creating a high turbulence and complete burning of the secondary production of combustion while heating the refractory walls above a pyrolytic temperature at different burning rates.
