Italy has been trying it’s best to follow the world in a clean energy reform despite having economic and political difficulties over the years. Italy has still managed to pull off a good noteworthy advancement in the field of energy.
Italy has been focusing on various methods of sustainable and clean energy generation. Italy has embraced the common renewable forms such as solar, wind, tidal and geothermal energy, also, it has tried out Heat Recovery Steam Generators (HRSGs) which have been deployed by only a few countries around the globe. A heat recovery steam generator or HRSG is an energy recovery heat exchanger that recovers heat from a hot gas stream, usually coming from gas turbines or engines. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle). HRSGs consist of four major components: the economizer, evaporator, superheater and water preheater. The different components are put together to meet the operating requirements of the unit. Modular HRSGs can be categorized in several ways such as the direction of exhaust gas flow or several pressure levels. The systems could be of two types: one, where gas turbine is coupled directly to the steam generator and the major components are disposed in line: superheater, evaporator, and economizer (one pressure level); other type is a classic steam generator: the exhaust gas coming from gas turbine reaches the burners, which are installed on boiler front wall. The HRSG industry market is not that concentrated as the manufacturing technology of HRSG is relatively much more mature than some high-tech equipment.
Italy is one of the few countries that are remarkable in his technology and have made noteworthy advancements in this sector of the energy market of HSRGs.
