Abstract

A boiler for the generation of hot water, characterized by having a hearth that is protected from refractory masonry and is formed by two water collectors located one in the upper part and the other in the lower part, according to the longitudinal axis of the boiler ; and an inner series of grafted tubes between the upper and lower collectors which start in divergent direction of the upper collector, then continue vertical and parallel, leaving between them the body of the hearth, and then converge towards the lower manifold, so that it is created a first indoor closed circuit of water circulation; an outer series of water pipes grafted on the upper and lower manifold and again from the lower to the upper on the opposite side, so that a second external closed circuit of water circulation is created at a distance from the first; elongate sheets welded at their longitudinal edges to each pair of tubes of the inner series of tubes, so as to prevent the passage of the combustión gases through them, except at the top, where said closing plates are missing; some elongated sheets welded by their longitudinal edges to each pair of tubes of the external series of tubes, that close the passage of the gases except for below, with which the gases of the combustión coming from the home are forced to leave for the part upper of the 1st inner series of tubes and to circulate between the two series of tubes on each side, heating the water that circulates through the tubes and then going out to the lower expansion chamber, where the chimney is grafted.
