Abstract
A compact heat source is provided which includes a bell-shaped or conical recuperator that surrounds a combustion chamber. The recuperator consists of parts that are axially tensioned against one another, so that a stable positioning of a partition wall provided with projections both on a bell-shaped outer wall and also on a bell-shaped inner wall is ensured.
Claims12
A heater for generating high temperature heat, comprising:
- an exhaust gas/air heat transfer device having a symmetrical configuration in an axial direction with a circular cross section, a combustion chamber disposed at least partially in an interior space enclosed by the exhaust gas/air heat transfer device, said exhaust gas/air heat transfer device including an outer wall and an inner wall with sides of the outer and inner walls being in spaced apart relation to each other, a partition between said outer and inner walls, said partition having projections engageable with said inner and outer walls, and said inner wall and outer wall being separated by a distance of less than about 2% of the diameter of the exhaust gas/air heat transfer device.
A heater for generating high temperature heat, comprising:
- an exhaust gas/air heat transfer device having a symmetrical configuration in an axial direction with a circular cross section, a combustion chamber enclosed by the exhaust gas/air heat transfer device, said exhaust gas/air heat transfer device including an outer thermal insulation wall and an inner thermal insulation wall, and said outer thermal insulation wall having a thickness which decreases in an axial direction in which a thickness of the inner insulation wall increases.
A heater for generating high temperature heat, comprising:
- an exhaust gas/air heat transfer device having a symmetrical configuration in an axial direction with a circular cross section, a combustion chamber disposed at least partially in an interior space enclosed by the exhaust gas/air heat transfer device, a high temperature heat transfer device connected to said combustion chamber, and said high temperature heat transfer device being transversed by fluid which passes through an endochemical transformation during operation of said heater.
