Abstract

The burner is fitted with air and fuel connections and with an ignition spark plug fitted with an extension so that the electrodes are within the combustion chamber. The combustion chamber is an innter tube with a number of holes allowing exhaust gases to pass directly into the outer tube, most of the gases passing into the outer tube through the open end of the chamber. The gases then flow back through the annular space which lies between the inner tube and the outer tube. The exhaust gases are expelled through an outlet port. An alternative to the radial holes is to drill the holes at an angle in the direction of flow of the gas.
