Definitions

  • the present procedure consists in obtaining electrical energy from the use of solid fuels, on the one hand, by an external combustion machine (steam turbine) and fluid fuels, on the other, by internal combustion (alternative engine); combining the thermal cycle of the second machine over the first.
  • an external combustion machine steam turbine
  • fluid fuels on the other, by internal combustion (alternative engine)

  • SUBSTITUTE SHEET (RULE 26) It will be in the form of residual heat. In addition, this work is obtained between two temperature levels, that is, thermal levels, one high and one other, lower.
  • the technique has taken care of maximizing the performance of these thermal devices using increasingly sophisticated machinery, obtaining the maximum production of electrical energy with the minimum consumption of primary energy, that is, minimizing residual heat.
  • Thermal machines are divided into exothermic or external combustion and endothermic or internal combustion.
  • the exothermic ones basically consist of a combustion boiler plus a steam turbine, generally and, the most used endothermic ones are the gas turbine and the alternative engine.
  • the gas turbine has the disadvantage of obtaining a lower performance than the alternative engine, but it has the advantage that the residual heat emits it at a high temperature, around 6QQ ° C, sufficient thermal level to generate steam to move a steam turbine, obtaining, the latter, a good performance.
  • the combination of both achieves high performance on the inverted primary energy.
  • the system that is provided as a novelty consists in obtaining electrical energy through the use of solid fuels, on the one hand and, of fluid fuels, on the other.
  • Solid fuels are burned in a boiler where steam is produced. This fluid is conducted to a condensation steam turbine that generates mechanical and, subsequently, electrical energy.
  • the vapor condenses at low pressure inside a condenser and at a low temperature, around 45 ° C.
  • Fluid fuels are burned inside an alternative engine, also producing mechanical and, subsequently, electrical energy.
  • Solid fuels have, as main drawback, the cost of operation and its low efficiency. If we apply the new invented energy extraction method, we observe how the performance and, as a result, the profitability of a joint installation of solid and fluid fuel increases considerably.
  • the most appropriate system would consist of a steam boiler where solid fuel is burned.
  • the steam would be driven to a condensation turbine and, as an internal combustion group, an alternative "Otto" cycle engine would be used.
  • the new energy policies lead to the use of renewable energy being, biomass, the pending subject in this process.
  • Biomass like the rest of solid fuels, has as its main drawback in the extraction of energy, the operating cost and its low yield, forcing governments to encourage such use based on premiums and subsidies, in order to make viable its operation.
  • a suitable example would be the installation of a thermal power plant in which biomass would be used as main fuel and natural gas as secondary fuel.
  • the main machinery of the installation would be:
  • This set would consume 70% of energy in biomass and 30% of natural gas, measured by its P.C.I.
  • SUBSTITUTE SHEET (RULE 26) A conventional combined cycle (gas turbine - steam turbine) running on the same fuel and the same amount, would not exceed, in the best case, 42% yield and, of course, with much more investment.
  • the main advantage of the system described lies in the high electrical performance obtained by associating the combustion of fluid fuels with solids by means of this new "combined cycle" system described, through conventional machinery; far superior to the performance obtained in combined cycles “gas turbine - steam turbine", without resorting to complex systems such as pyrolysis procedures, anaerobic digestion, gasification, etc. and, all this, at a lower cost of investment in capital goods.
