摘要

Improvements in the construction of heating boilers with reheater built inside for locomotives, with smoke pipe that are crossed by the flow of combustión gases in the direction from the hearth towards the smoke box of the locomotive, and with re-heater tubes that they are traversed by said gases in the opposite direction, with the use of tubes whose cross-section, in a manner known per se, is constantly or stepwise narrowed in the direction of the flow of the combustión gases, characterized in that the heating boiler is subdivided, means of a horizontal separating partition, in an upper vapor-forming enclosure and in a lower pre-heating enclosure, and the bundles of tubes in both enclosures are narrowed in the opposite direction.
