A high velocity 3 phase mixture is pumped down a drill string to a vortex swirl generator/hydrocyclone for 2 phase separation flow into a twin vortex combustion chamber manifold that swirls the air in and around the fuel and water mixture droplets (atomise) producing instant exothermic heat of combustion thereby producing a super-critical thermal spallation jet flow; with surface control of the water to fuel (kerosene) content allows temperature control between 400 °C and 1,800 °C with additional abrasive particles if required, axial pulse jets are also optional for further erosion to the rock face, allowing the spalling of all rocks with high strength to low ductile transformation temperatures. The spallation drilling system makes possible drilling of well bores to allow the use of steam drive and alternating steam injection within oil reservoirs and electrical power generation which are able to use super-critical HDR principles with water temperatures above super-critical 374 °C and critical pressure of 3,204 psi for expansion back to lower pressure with high quality steam. |
