Abstract

776,424. Generating combustion products under pressure. JUNKERS & CO., GES. Sept. 26, 1955 [Oct. 4, 1954], No. 27307/55. Class 51 (1). [Also in Group XIII] In an oscillating column type of combustion apparatus, particularly for heat exchange devices such as a gas-fired water heater, a cooling tube 7 is wound helically round the combustion chamber 4, the coils of the tube being spaced apart so as to form with the combustion chamber wall and an outer wall 8, a helical passage 9 which constitutes the resonator tube. The air inlet to the combustion chamber is shown at 1 and the combustible gas inlet at 2. The opening of the last coil of the cooling tube is closed by a plate 11, and gases issuing from the outlet 5 of the combustion chamber pass through the helical passage 9 which forms the resonator tube to the outlet 10. Water enters the coil 7 at 6 and discharges at 12. In Fig. 2 the cooling water coil 7 is of rectangular section, the upper and lower surfaces of the section being inwardly curved of semi-circular form. The coil is wound helically with the coils abutting, so that the combustion chamber 4 is formed by the inner walls of the coils and the resonator tube 9 is a helix of circular section. In Fig. 3 the cooling water tube 7 is of triangular section, the inner walls of the coils abutting to form the combustion chamber 4 while the resonator tube 9 is formed by the sides of adjacent coils and an outer wall 8. In another embodiment the cooling coil is again of triangular section and is wound around the combustion chamber to form the resonator tube.
