Abstract
A solid fuel bar preferred to be pressed from cleaned coal powder to a high density is led into a combustion chamber. Air is compressed to high pressure and temperature exceeding the self ignition temperature of the fuel bar and this compressed air is led into a combustion place in the combustion chamber, where the tip of the fuel bar moves into the compressed hot air and ignites and burns therein. The burned and expanded air is led into an expander, which drives the compressor, whereby a running combustion engine is obtained. The invention discloses the details, by which the ignition and combustion of the solid fuel bar in the engine is obtained.
Claims12
A combustion chamber which has in a housing at least one airflow passage for the continuous supply of compressed air to a combustion place in combination with a fuel supply arrangement and ignition means to supply fuel into said combustion place and to ignite said fuel in said air in said combustion place,
- wherein said fuel supply arrangement comprises, in combination, a fuel container with a storage space, a transfer mechanism and longitudinally straight rigid fuel bars of equal cross sectional configuration throughout their entire lengths from their front tips to their rear ends, with said fuel bars having at least the same density and heating value as an average grade of anthracite,
- wherein said transfer mechanism includes a linear guide way with at least one linear inner face which meets at least one linear outer face of a fuel bar for guidance of said fuel bar at longitudinally forward movement of said fuel bar,
- wherein said transfer mechanism includes a linearly moving member,
- wherein said linearly moving member touches the rear end of at least one of said fuel bars to move the respective fuel bar forward in said linear direction and through said guide way to cause said fuel bar to meet with its front tip said compressed air in said combustion place for burning in said combustion place,
- wherein a compressor is communicated to said airflow passage to supply in a continuous operation in average a first volume per unit of time of compressed hot air of a temperature exceeding the self-ignition temperature of said fuel of said fuel bar,
- wherein the forward speed of said linear movement of said fuel bar towards said combustion place per equal unit of time defines by the cross sectional area of said fuel bar multiplied with said forward speed a second volume with said second volume consisting of fuel, and,
- wherein said first volume consists of the minimum of quantity of air which is required to burn said second volume which consists of fuel in said first volume of air completely.
