    Combined cycle plants equipped with systems for using residual thermal energy from both gas turbines that operate with Brayton cycles and Diese! including those of marine propulsion are based on:
    -the cascade association of the Brayton cycle gas turbine operating with a fossil fuel followed by a Rankine cycle fed with the heat recovered from the exhaust gases evacuated by the Brayton cycle gas turbine.
    - the cascading association of one or more alternative internal combustion engines operating with natural gas or other fossil fuel such as fuel oil, followed by a Rankine cycle fed with residual heats not used or rejected by the alternative engine, where the cycle Rankine can be organic, including the Rankine cycle with one or two pressure levels.
    - the cascade association of an alternative internal combustion engine operating with natural gas or other fossil fuel such as fuel oil, where the engine's exhaust gases pass to the turbo-blowers and a gas turbine that drives a generator, and subsequently, the gases evacuated by the turbo-blowers and the gas turbine go to a steam generator with which a Rankine cycle steam turbine is connected to the same electric generator mentioned.
    - the cascading association of the alternative internal combustion engine operating with natural gas or other fossil fuel such as fuel oil, where the engine exhaust passes to the turbo-blowers and from there to a coupled Stirling or Ericsson cycle machine To an electric generator.
    The invention called THERMAL PLANT OF ENERGY CONVERSING MODULES COUPLED IN CASCADE WITH FOSSIL AND / OR RESIDUAL ORIGIN HEAT differs essentially from the mentioned combined cycles in that the residual heat rejected by some industrial processes, as well as the combustion gases of origin Fossil can alternatively be combined to feed a machine composed of a series of heat recuperators where each of them feeds a cascade of actuator modules operating with thermal cycles of closed processes of high thermal efficiency.

    - supply lines and evacuation of thermal heating fluid, (7) and (8),

    - a thermo-actuator cylinder (11) that houses the heat exchangers (15) and (18) through which the heating and cooling thermal fluids circulate, responsible for transferring heat from the heating thermal fluid to the working thermal fluid, and subsequently, from the working thermal fluid to the cooling thermal fluid.
    The heating thermal system operates with two sources of thermal energy:
    - source of thermal energy of fossil origin with fuels such as fuel oil, diesel, natural gas, hydrogen, among others available, and,
    - source of thermal energy of high, medium or low temperature residual origin, which is used by heat recovery exchangers.
    The THERMAL PLANT OF ENERGY CONVERSING MODULES COUPLED IN CASCADE WITH FOSSIL AND / OR RESIDUAL ORIGIN HEAT is implemented under three alternative structures:
    - Thermal plant designed to operate with heat from both sources of thermal energy simultaneously (combustion heat of fossil origin and heat of residual origin), as shown in Figure 3,
    - Thermal plant designed to operate with fossil fuels heat only, according to figure 4, and
    - Thermal plant designed to operate with heat of residual origin only, shown in Figure 5.
    The thermal plant designed to operate with fossil and residual heat simultaneously shown in Figure 3 is composed of at least the following components:
    - fuel supply line (1) to the combustion chamber (23),
    - air supply duct (2) to the combustion chamber (23),
    - circulation pump (5) of the heating circuit,
    - heating fluid inlet duct (7) to the thermomechanical converter module,
    - heating fluid outlet duct (8) f of the thermomechanical converter module,
    - thermal cooling fluid inlet conduit (9) to the thermomechanical converter module,

    - thermal cooling fluid outlet duct (10) of the thermomechanical converter module,
    - thermomechanical converter module (20), which includes all the accessories of each thermo-actuator cylinder,
    - air supply blower (21) to the combustion chamber (23),
    - combustion air heater (22),
    - combustion chamber (23),
    - waste heat recovery exchanger (26),
    - heat recovery heat exchanger (31) for thermal feeding of high temperature modules,
    - heat recovery heat exchanger (32) for thermal feeding of low temperature modules.
    The operation procedure of the thermal plant to simultaneously use combustion heat of fossil origin and heat of residual origin, as shown in Figure 3, consists of simultaneously taking advantage of the two thermal energy sources (of combustion of fossil origin and residual ), for which the air supply blower (21) to the combustion chamber (23), pumps atmospheric air through the combustion air heater (22) through the air supply conduit (22), while through the fuel supply line (1) fossil fuel is added, such as fuel oil, diesel, natural gas or hydrogen, among others. High temperature combustion gases pass through the heat recovery heat exchanger (31) of thermal feed to a cascade of thermo-mechanical converter modules (20). The combustion gases that leave the high temperature heat exchanger (31), then pass through the heat recovery heat exchanger (32) to the thermo-mechanical converter modules (20) operating at low temperature. The combustion gases leaving the low temperature heat exchanger (32) pass through the air heater (22) into the atmosphere, where they give heat to the combustion air with the consequent increase in temperature.
    The heat transfer from the high and low temperature heat recovery exchangers (31) and (32) is carried out by means of a heating thermal circuit through which a heating thermal fluid circulates driven by the circulation pump (5) of the heating circuit, which captures heat in the waste heat recovery exchanger (26), where it increases its temperature and then recovers heat from the

    - combustion chamber (23),
    - heat exchanger for thermal feeding of high temperature modules
    (31),

    (32)
    The operation procedure of the thermal plant designed to operate with fossil fuel fuels only shown in Figure 4, consists in harnessing the heat of the thermal energy source from fossil fuel combustion, for which the blower air supply (21) to the combustion chamber (23), pumps atmospheric air through the combustion air heater (22) through the air supply duct (2), while through the supply duct
