Abstract
Heat recovery apparatus able to be installed, in particular, in a domestic chimney and able to provide hot air and hot water, comprising a horizontal lower chest 2 in which is formed a combustion chamber 12, a vertical chest 1 in which are disposed deflectors 27 and a horizontal upper chest 3, the air being heated during its passage through the vertical chest 1 and in the upper horizontal chest 3, and the water being heated during its passage in the neighborhood of the combustion chamber 12 and in the vertical chest.
Claims13
Heat recovery apparatus intended to be installed in a domestic chimney and adapted to burn a fuel for heating air and a fluid, comprising:
- a vertical chest provided at its lower part with at least one opening for admission of air and at its upper part with at least one opening for escape of air;
- a horizontal chest extending from the lower part of said vertical chest, the upper surface of said horizontal chest forming a hearth;
- a combustion chamber formed in said horizontal chest and provided with an air inlet duct and a smoke duct;
- and
- at least one duct extending in the neighborhood of said combustion chamber for circulating of said fluid, said combustion chamber being limited laterally by substantially vertical walls, at its lower part by a bottom provided with a grid and at its upper part by said upper surface of said horizontal chest provided with an opening whereby said opening can be provided with a grid for permitting escape of ash therethrough and through said combustion chamber and said bottom grid when a fire is desired on said upper surface or with a solid plate when a fire is desired in said combustion chamber or on said upper surface.
