PERFECCIONAMIENTOS EN ESTUFAS PARA LA COMBUSTION DE COMBUS- TIBLE SOLIDO, TAL COMO MADERA, COQUE, CARBON DE PIEDRA Y SI-MILARES

摘要

A stove for combustion of solid fuel comprises a primary combustion chamber (1) and a secondary combustion chamber (6) with separate supply of combustion air to both chambers. Both chambers (1, 6) are thermally insulated in such a manner that the secondary combustion chamber is better heat insulated than the primary combustion chamber. The secondary combustion chamber is a two-stage chamber. There is provided a heat exchanger surface (9) between an inlet passage (8) for the secondary combustion air and the outlet (10) for the hot combustion gases from the secondary combustion chamber (6).
