High efficiency cogeneration

Cogeneration is the process that allows the simultaneous production of kinetic energy, turned into electricity, and heat, which can be used for heating purpose and/or industrial production tasks. It allows not to waste any residual heat associated to production fumes and cooling circuits in the environment, otherwise lost. Cogeneration is a technology extremely useful in those industrial activities that need electric and thermal energy at the same time. The related energy saving turn into significant money saving, and the possibility to achieve bonuses for high efficiency plants is an opportunity that RENOVIS can help you catch. Gas and steam turbines, gas-steam combined cycles, internal combustion engines, micro turbines, etc. are all common cogeneration systems.

Cogeneration allows to save about 32% of the original consumption of primary energy, assuming the following data:

  • standard thermal performance: 85%
  • standard electric performance: 40%
  • thermal performance with cogeneration: 45%
  • electric performance with cogeneration: 38%

Another technology allowing to maximize benefit is trigeneration: it is a cogeneration process where produced heat is used to generate “cold” through proper reverse absorption cycles (see Chillers section).

Another application is the efficiency improvement of existing cogeneration plants thanks to the adoption of system allowing to recover all waste heat through fumes.

RENOVIS guarantees the best customer-oriented assistance both for cogeneration and trigeneration feasibility studies.
