Gas Turbine-CHP Stations with HRSG

Gas Turbine-CHP Stations with Heat Recovery Steam Generators (HRSG):

Depending on the boundary conditions, for example if heat is used in form of hot water or in case of ratios "electricity to fuel price" above 3.6, Gas Turbine Combined Heat and Power (CHP) Stations with Heat Recovery Steam Generators (HRSG) might get the economically benefitial solution.

In these cases HUTTER FREI POWER delivers Gas Turbine CHP Stations with HRSGs, optimised based on the individual project boundary conditions.

With Gas Turbine CHP Stations with HRSGs, the heating energy of the GT exhaust gas is utilised in a downstream Heat Recovery Steam Generator.
HRSGs can be equipped with additional firing or without additional firing. In cogeneration applications, the optimisation of Heat Recovery Steam Generators leads to additional firing.

The size of the additional firing for HRSGs is restricted due to technical and/or economic reasons.

Gas Turbine CHP Stations with HRSGs can be equipped either with Steam Turbines or without Steam Turbines.
In applications with Steam Turbines the Heat Recovery Steam Generators are, depending on the project boundary conditions, designed as single pressure Steam Generator or as multi pressure Steam Generator (dual pressure or triple pressure Steam Generator).
 

HUTTER FREI POWER delivers Gas Turbine CHP Stations with different circuit concepts:

• Gas Turbine CHP Stations with additionally fired multi pressure Heat Recovery Steam Generators and Steam Turbines
  (Combined Gas Turbine- and Steam Turbine CHP Stations)
• Gas Turbine CHP Stations with additionally fired single pressure Heat Recovery Steam Generators and Steam Turbines
  (Combined Gas Turbine- and Steam Turbine CHP Stations)
• Gas Turbine CHP Stations with additionally fired low pressure Heat Recovery Steam Generators without Steam Turbines
   

Area of Application:

• Industries, trade and district heating with simultaneous and continuous hot water and electricity needs, or in the case of price ratios of electricity to fuel > 3.6 for applications with useful steam and electricity needs.
