Abstract
A stove for burning solid fuel such as wood, coal or briquets in a more efficient manner utilizes preheated outside air for primary and secondary combustion and has tempered glass windows for observation. The combustion air flow is directed so as to minimize obscuring of the glass by deposits of unburned volatiles. A fire chamber is provided with self-feeding grate, and the stove also has a secondary grate, a high proportion of radiating and convective surfaces, a heat exchanger, a cooking surface, an automatic linkage between a fuel loading door and an opening-reducing damper to limit back drafts and thermostatic control to ensure complete combustion and efficient heat exchange. The self-feeding grate has a thermostatic grate shaker to promote unattended complete combustion, and can be replaced to match the fuel used.
