Combined Cycle CHP Stations SYSTEM HUTTER are specially suitable for Enterprises, who need continuously and simultaneously useful heat and electricity.
The fuel gas (e.g. natural gas) is available in required quality and in sufficient quantity or a fuel gas pipeline can be built with economically reasonable lenght
The necessary prerequisites at the Operator for the operation of a gas turbine and a steam turbine are fulfilled or can be gained by working within the execution of the project
The annual operation time of the gas turbine is normally at least 5000 hours/year
Either the public electrical grid is reliable and stable or the new CHP Station can be operated continuously in island mode and thereby can cover with its operating range the energy demand of the Customer
Simultaneous need of electricity and useful heat
The Customer preferably need useful heat in form of steam (process steam or district heating steam)
If an existing steam turbine CHP Station can be extended with an upstream installation of a gas turbine to a Combined Cycle CHP Station SYSTEM HUTTER, than a CHP Station SYSTEM HUTTER normally is economically optimal for the application with useful heat in form of hot water as well
Without consideration of subsidies or other governmental support, the following basic rules are valid for the economic use of Combined Cycle CHP Stations SYSTEM HUTTER:
The price ratio electricity to fuel is in the range between 1.8 and 3.6, but this may deviate significantly depending on the project boundary conditions
The operational electricity-to-heat ratio (electricity demand in MW divided by useful heat demand in MW) is in the range between 0.2 and approximately 0.8
It has to be emphasised, that some further important project boundary conditions do have significant influence on the choice of the optimal power plant process. All project boundary conditions and their influence shall be investigated in a study, prior to the choice of the process for the project execution.
Based on above prerequisites, the use of Combined Cycle CHP Stations SYSTEM HUTTER is recommended for the following Customer branches:
