The heater of subsuperfu00cdcie method to heat an area of subsuperfu00cdcie

摘要

The surface heater and method for heating an area of subsuperfu00cdcie. In one aspect, the present invention provides a heater comprising: a subsurface conduit fuel gas supply conduit; a supply of oxygen and an outer housing transmitter including the refractory porous medium heat.The conduit to supply fuel gas and oxygen supply conduit are configured as a pair of concentric provisions within a refractory porous medium and coupled to a plurality of jets of gas prepared in porous refractory. The porous refractory having provisions in a plurality of combustion products from the conduits of return gas.The products of combustion of the gas conduits are configured to receive gas combustion product of refretu00e1rio porous. Also provided in another aspect of the present invention is a method for heating a subsurface zone.
