ABSTRACT:
A solid fuel preferred to be prepared from cleaned and pressed coal powder to a high density is led into a combustion chamber. Air is compressed to a high temperature which exceeds the self ignition temperature of the mentioned solid fuel. This compressed air is also led into the combustion chamber to meet there the tip of the solid fuel sheet and to ignite and burn the fuel in the hot air in the combustion chamber. The hot burned gas can then be led into an expander and the expander can drive a compressor for the supply of the mentioned hot air. The device then forms a combustion engine with continuous combustion in an external combustion chamber. In my parental U.S. Pat. No. 4,809,503 the solid fule is a fuel bar. This present application deals mainly with a solid fuel sheet or tape which is wider than it is thick. Thereby it is secured that the fuel portions meet exactly the required amounts of hot air locally at a wide meeting and burning place.
