The Combined Cycle CHP Station SYSTEM HUTTER is an own-developed and patented Combined Gas Turbine- and Steam Turbine CHP Station with radiation-type SYSTEM HUTTER Steam Generator for the simultaneous generation of useful steam and electricity.
The base of the concept gave a research assignment from the german federal ministry for research
and development, with the target to find out the electrical potential of combined heat and power
plants for the industry in germany and to develop suitable measures to increase the electricity generation from these combined heat and power plants.
Today this target is most important, because CO2- diminution became political and
human desire.
The installed Combined Cycle CHP Stations SYSTEM HUTTER have reached 790`000 operation hours and 92 operation years.
The longest Combined Cycle CHP Station SYSTEM HUTTER is in operation since 1990 and has accumulated about 190'000 operation hours.
The fleet time-reliability over the entire period has achieved values > 99 %.
Existing Plant:
no Plant or low- pressure Steam Generator
Solution:
New Combined Cycle CHP Station SYSTEM HUTTER with new Gas Turbine, new SYSTEM HUTTER Steam Generator and new Steam Turbine
Customer Benefits:
Generation of electricity while keepting a high fuel utilisation factor (for back-pressure steam turbine processes up to > 90 %) and consequently saving electricity purchasing cost and achieving electricity sales earnings.
Existing Plant:
Steam Turbine CHP Station
Solution:
Repowering of the existing Steam Turbine CHP Station by retrofitting the existing Steam Generator to a SYSTEM HUTTER Steam Generator and replacement of the existing Boiler Burner, and to install a new Gas Turbine while using the existing Steam Turbine.
Customer Benefits:
Increasing the electricity generation by installing the Gas Turbine while keepting a high fuel utilisation factor (for back-pressure steam turbine processes up to > 90 %) and consequently saving electricity purchasing cost and achieving electricity sales earnings.
Increasing the maximum possible rates of load changes.
Decreasing the minimum possible part load of the Steam Generator and de-coupling the generation of electricity and useful heat and consequently resulting to an extended part load capability, faster load changes and higher operation flexibility.
Existing Plant:
Gas Turbine with low- pressure Heat Recovery Steam Generator
Solution:
Extension of the existing Gas Turbine with low-pressure Heat Recovery Steam Generator by replacement of the Steam Generator with a new high-pressure SYSTEM HUTTER Steam Generator being able to achieve higher nominal steam generation values and by installing a new Steam Turbine while using the existing Gas Turbine.
Customer Benefits:
Increasing the electricity generation by installing the Steam Turbine while increasing the original low fuel utilisation factor to a high fuel utilisation factor (for back-pressure steam turbine processes up to > 90 %) and consequently saving electricity purchasing cost, achieving electricity sales earnings and achieving lower fuel consumptions relative to the electricity generation.
Increasing the maximum possible rates of load changes.
Decreasing the minimum possible part load of the Steam Generator and de-coupling the generation of electricity and useful heat and consequently resulting to an extended part load capability, faster load changes and higher operation flexibility.
Existing Plant:
Gas turbine with high pressure Heat Recovery Steam Generator and Steam Turbine
Solution:
Extension of Gas Turbine with high-pressure Heat Recovery Steam Generator and Steam Turbine by modifying the Steam Generator to a SYSTEM HUTTER Steam Generator using the existing Gas Turbine being able to achieve higher nominal steam generation values and by widly using the existing Heat Recovery Steam Generator and by adding a Steam Turbine to the existing Steam Turbine.
Customer Benefits:
Increasing the electricity generation by installing the additional the Steam Turbine while increasing the original low fuel utilisation factor to a high fuel utilisation factor (for back-pressure steam turbine processes up to > 90 %) and consequently saving electricity purchasing cost, achieving electricity sales earnings and achieving lower fuel consumptions relative to the electricity generation.
Increasing the maximum possible rates of load changes.
Decreasing the minimum possible part load of the Steam Generator and de-coupling the generation of electricity and useful heat and consequently resulting to an extended part load capability, faster load changes and higher operation flexibility.
