Abstract
The utility model relates to a natural-ventilating automatic low-pressure natural gas combustor of a heating stove for oil fields. The utility model comprises a cylindrical nozzle casing (12) whose front end has a plurality of oblong inclined spinning holes (6) sheathed on the periphery of the included angle of the axial line, and the front end of the cylindrical nozzle casing (12) forms an included angle beta of 15 DEG to 30 DEG with the axial line. The back inner wall of the spinning hole (6) is provided with a flame holding sheet (5). The rear end of the casing is provided with an oblong primary air inlet (11), and the rear end head is connected with a shell cover (10) of which the external diameter is larger than that of the cylindrical nozzle casing (12). The cylindrical nozzle casing (12) is sheathed with a cone of which the front end forms an included angle beta of 15 DEG to 30 DEG with the axial line. The rear end of the cone is in a cylindrical shape, the end head is an annular jacket (2), and a gas inlet (7) is arranged on the lower part of the round wall on the rear end of the jacket (2). A cone-shaped wind-guiding sleeve (4) which forms an included angle alpha of 20 DEG to 40 DEG with the axial line is sheathed on the external front end of the jacket (2). The external front end of the coned-shaped wind-guiding sleeve (4) is connected with an ignition electrode frame (17), and the flange-shaped rear end of the coned-shaped wind-guiding sleeve (4) is connected with a quadratic air regulating shutter (8) through a quadratic wind-inlet plate (13) and fixed on the jacket (2). The quadratic wind-inlet plate (13) is externally provided with a quadratic regulating wind plate (3) of a regulating rod (1). The primary air inlet (11) of the nozzle casing (12) is externally provided with a primary wind regulating plate (14) of the regulating rod (1). The utility model is a device which is matched with a heating stove for oil fields.
