Abstract
A heat input device for a heat engine comprises a combustion device which is adapted to support surface burning of a fuel and oxidant mixture and a heat exchanger which is adapted to transfer the heat from the hot surface against which the surface burning takes place to the working fluid of the engine.
Claims11
A system of the type comprising, in combustion, a heat engine and a heat input device, said heat engine having a gas working fluid wherein:
- said heat input device comprises a unitary heat exchange body having an extended surface against which surface burning of a fuel and oxidant mixture can take place, and a heat exchange surface forming part of the heat exchange body and in thermal contact with the extended surface, said heat exchange surface being directly heated by conduction of heat from the extended surface and adapted to transfer this heat to the working fluid of the engine.
The system of further comprising a heat exchanger adapted to exchange heat between the exhaust of the surface burning device and the compressor delivery air.
The improvement of claim 11 wherein said surface burning takes place within a matrix having an extended surface.
In a system of the type including a heat engine and a surface burning heat input device the improvement wherein said surface burning heat input device comprises:
- a unitary heat exchange body having an extended surface against which surface burning of a fuel and oxidant mixture can take place, and a heat exchange surface forming part of the heat exchange body and in thermal contact with the extended surface, said heat exchange surface being directly heated by conduction of heat from the extended surface and adapted to transfer this heat to the working fluid of the engine.
