Abstract

Some improvements in fluid heaters with forced circulation, characterized by the provision of right-side walls that form an oven for the flow of hot gases, there being means for supplying heating gases at a high temperature to said oven, said walls comprising a first group of Fluid heating tubes directed upwards and laterally separated from each other, whose tubes are rigidly joined by means of metal plates arranged in the intermediate spaces between the tubes, to form a lower part of said wall, extending a second group of tubes for the fluid heating, separated from each other and directed upwards, arranged for the parallel flow of fluid through them and rigidly joined by metal plates arranged in the intermediate spaces of the tubes, to form an upper part of said wall and possessing their longitudinal axes aligned with the longitudinal axes of the tubes of the first group, communicating connection headers with the tubes of the first group, from which they receive fluids that flow from them and mix them, distributing the mixed fluids to the tubes of the second group, providing means for the supply of fluid to the tubes of the first group and said first and second groups of tubes being constructed in such a way as to provide fluid flow in the furnace only in the upward direction, some of the tubes of the first and second groups being bent out of the plane of the wall on a first and second level respectively, for connection to header or connection elements and interposed and laterally separated from each other in the plane of the wall between the first and second levels, the second level being underlying the first level and existing support elements that extend transversely through the longitudinal axes of said tubes and located externally with respect cto the spaces between the tubes interposed with each other, said support means being fixed to the mentioned first and second groups of tubes, whereby the load of said first and second groups of tubes is transferred to the outside of the spaces mentioned towards the mentioned supports and then said second group of tubes, in such a way that the interposed tubes are not joined by welding and said first and second groups of tubes generate a compression force along said support means.
