Space heating method and apparatus

Claim 1

A COMBINATION LIQUID AND GASEOUS FUEL BURNER COMPRISING AN ELONGATED, UNOBSTRUCTED COMBUSTION CHAMBER HAVING AN OPEN DISCHARGE END AND AN OPPOSITE CLOSED END THROUGH WHICH A PLURALITY OF SUBSTANTIALLY PARALLEL GAS PASSAGEWAYS EXTEND TO SAID CHAMBER, ADJACENT ALTERNATE ONES OF SAID PASSAGEWAYS BEING CONNECTED RESPECTIVELY TO SOURCES OF AN OXYGEN GAS AND A FUEL GAS TO DELIVER CORRESPONDING, SPACED, SUBSTANTIALLY-PARALLEL STREAMS OF AN OXYGEN GAS AND A FUEL GAS INTO THE CLOSED END OF SAID CHAMBER DIRECTED SUBSTANTIALLY TOWARD SAID CHAMBER DISCHARGE OPENING, SAID GAS STREAMS MERGING WITH ONE ANOTHER AT AN INTERMEDIATE ZONE OF SAID CHAMBER, IN A RELATIVELY HIGH VELOCITY COMBUSTION MIXTURE OF SAID OXYGEN GAS AND FUEL GAS AND BURNING IN A FLAME CONFINED AT LEAST IN PART BY THE WALLS OF SAID CHAMBER, THE PARALLEL GAS PASSAGEWAYS BEING CLOSELY ADJACENT TO ONE ANOTHER WITH ZONES BETWEEN THEM INTO WHICH GAS FROM THE STREAMS IS DRAWN TO FORM A RELATIVELY LOW VELOCITY MIXTURE OF OXYGEN GAS AND FUEL GAS WHOSE COMBUSTION FORMS ANCHORING FLAMES CONTIGUOUS WITH SAID GAS STREAMS EFFECTIVELY PREVENTING EXTINCTION OF THE FLAME FORMED BY COMBUSTION OF SAID RELATIVELY HIGH VELOCITY COMBUSTION MIXTURE, AND A LIQUID DELIVERY PASSAGEWAY EXTENDING SUBSTANTIALLY CENTRALLY THROUGH SAID CLOSED END OF SAID CHAMBER HAVING MEANS FOR DISCHARGING A STREAM OF LIQUID FUEL THERETHROUGH TOWARD SAID CHAMBER DISCHARGE OPENING INTO SAID RELATIVELY HIGH VELOCITY GAS MIXTURE WHEREIN SAID RELATIVELY HIGH VELOCITY MIXTURE EFFECTIVELY ATOMIZES SAID LIQUID STREAM TO FACILITATE COMBUSTION THEREOF, AND GAS FLOW REGULATING MEANS FOR THE OXYGEN AND FUEL GAS, THE REGULATING MEANS FOR THE OXYGEN AND FUEL GAS BEING INDEPENDENTLY ADJUSTABLE FOR CONTROLLING THE SUPPLYING OF OXYGEN GAS FOR COMBUSTION WITH SAID LIQUID FUEL BY CONTROLLING THE RELATIVE FLOWS OF SAID OXYGEN GAS AND FUEL GAS STREAMS.
