Abstract

Hot air generator, perfected, characterized by being constituted by two concentric cylindrical chambers, of different diameter, delimited by two walls of different thickness, of sheet welded by its edges, being the central one the combustión chamber of solid materials, such as firewood, coal or the like and said chamber having a basal grid for evacuating the ash falling in a drawer for its extraction, three legs equidistant to support the whole, two tubes of variable length equipped with air trap doors and regulation of the shot and communicating with the outside through the upper base, where it also incorporates a chimney for evacuation of smoke and a lid with handle to load the fuel to the generator, which has a semicircular development, being hinged to the rest of the plane upper, having the combustión chamber a series of generatrices joists of section in t, united to his pa internal network, reinforcing it, arranged housed between said beams, a series of curved refractory bricks, to accommodate the profile of the sheet, protecting its integrity and presenting the outer annular chamber, in its lower part, laterally, nozzles of variable diameter, according to power, for supply by means of a turbine of low pressure, of air to its interior, whose fluid is extracted clean and hot, by means of two independent pipes, defined on the side of its upper part, being arranged inside said annular chamber, two spiral strips, superimposed, linked to the base and the inner cylinder, designed to cause a longer vehiculation, of the air supplied by the turbine and therefore a slowed upward movement of the same, allowing it to extract a maximum of the heat power of the camera.
