Abstract

Gas burner for laboratories characterized essentially by being constituted by a lower tube for the entrance of the gas, which at the top has a thread to the outside, said tube ending in circular holes arranged around a frusto-conical piece coinciding with the axis of said tube; being coupled, in the threaded part of the lower tube, a washer or saucer, with central hole provided with internal thread, its function being to regulate the air intake; existing in the upper part of the lighter, a tubular piece, constituted by a superior tube for the exit of the mixture of gas and air, and a lower part in the form of a bell, where the mixture of gas and air takes place, this bell on another inferior piece, cylindrical, forming the three pieces a single body; a dish with orifices for air entry, housed inside a cylindrical lower part, is distributed circularly around an orifice, with internal thread, which extends superiorly in tubular form, ending in a truncated-conical tip with a central hole of gas outlet; coupling inside the hole provided with internal thread, the upper end part of the lower gas inlet tube, regulating the passage of this as more or less threaded the upper part of the lower gas inlet tube in the central tubular orifice presents the aforementioned plate, since this will depend on the space left free between the wall of the cone of the lower tube and the walls of the tubular orifice of the plate arranged in the lower part of the upper tube, a space that is regulated by actuating the bell of the upper tube .
