Abstract: The present invention relates to the field of energy recovery from hot exhaust gases, a type of system that is widely used in industrial generator assemblies to produce steam used in industrial processes or cold to cool perishables or to cool environments. The system according to the present invention applies to the recovery of energy from exhaust gases in small generator assemblies, smaller than 10 MW, and comprises a turbo (1) connected to the exhaust gas outlet (2) in a small power plant generator assembly (3) and in which said turbo (1) is connected to a hydraulic pump (4), which generates pressure and transmits this pressure to a hydraulic pressure accumulator (5) which, in turn, sends hydraulic fluid under pressure for a hydraulic motor (6) of constant speed, which moves a pulley (7), and said pulley (7), in turn, moves another pulley (8), installed directly on the alternator shaft (9) of the generator assembly (3).

Abstract: An autonomous modular device for an electric generating plant is described which may be in the form of a container that makes use of a vehicular engine adjacent to the canopy of a modular structure. A drycooler heat exchanger, with a layout different from the other existing layouts, implying improvements in the use of this type of autonomous generator system, is provided insofar as it provides easy transport, adequate consumption without mechanical loss and high energy efficiency. In one embodiment the vehicular engine is placed under the canopy of the modular structure, wherein a drycooler heat exchanger is accommodated, and not an engine radiator, with a different arrangement from the other existing units. A second embodiment is adapted to places where there is no physical space for the model including the heat exchanger under the canopy, forcing the installation on the ceiling of the installation, or for other installations.

Abstract: Structural modules for layout of modular power plants are disclosed. The structural modules comprise a substation module and a power house module, basically formed by platforms having stringers and crossbars designed for the mounting of containment sheets. Both modules include interconnections including, for example, projecting tabs for the mechanical mounting of fixation elements enabling the connection between the modules and the mounting of columns, crossbars and lifting frame so as to form a structural skeleton suitable to contain the canopies, hinged doors and sliding doors and other mechanical structures making up the spatial areas designed for the installation of various equipment, such as a group of generators, fuel tanks and tanks for containment of liquids, motors, busbars. The substation module forms a support base whose stringers and crossbars are lined with containment sheets which, in turn, are secured by welds.
