Objectives: The objectives of the CHEP project are two fold:

• to study, define and test the most critical and innovative components to be further integrated in a high efficiency, low cost and low emission small gas turbine CHP system;
• to show the validity of the technical choices.

The most critical components of the high efficiency gas turbine system, in the power range from 200 up to 350 kW are: the high efficiency aerodynamic components of the advanced, inter-cooled, recuperated gas turbine; the heat-exchanger recuperator; the catalytic combustor to achieve the "zero" emission goal; and the integrated, into the turbo-machinery shaft High Speed Alternator (HAS) for cost reduction.

Description of work:
The work is divided into seven major tasks:

• System analysis: to fix the technical inputs and targets by thermodynamic analysis.
• Inter-cooled compressor: to design the two inter-cooled compressor stages in view of a low cost production and an isentropic efficiency better than 84%.
• Turbine: to design a turbine stage with a service life higher than 30 000 operating hours and an isentropic efficiency of more than 87%
• Static heat recuperator: to select reliable, low cost, compact technology to meet the targets of pressure drop<7%, efficiency >90% and free maintenance service >30000 hours.
• Combustion: to design a combustion chamber with a pre burner, an air fuel mixer and a catalytic section and to prove the objectives of NOX, CO and UHC emissions below 9 ppm, reliability of the technology (over 8000 operating hours) and capability to use LHV fuels (biogas).
• High Speed Generator: to design, manufacture and test the High Speed Alternator and associated electronics. To study the integration of HSA into the turbine shaft for cost reduction. The electrical generator efficiency goal being > 92%.
• Management and exploitation plan: to manage the project and to exploit the results; to measure the gas turbine final production cost objectives of 300/kW and the maintenance costs of 0.005 /kWh; to assume the dissemination of the results.

Expected Results and Exploitation Plans:

The development of the major critical components of an efficient, innovative small gas turbine CHP system fully complies with the EC targets to reduce CO2 emissions by creating an improved combined heating and power system as opposed to the separate power and heat generating systems. The more efficient thermodynamic gas turbine cycle, which will increase the efficiency of the small gas turbine from between 20 and 25% to more than 35%, will produce a reduction of more than 10% in CO2 emissions. The innovative catalytic combustor, which is one of the main developments, is the most effective way to reduce the emission of pollutants (NOX and CO) to a level which will be required in a the near future (one "digit" emission level). It will also enable low heating value fuels issued from biomass (biogas) to be efficiently burnt. The results will contribute to improve research laboratory and universities know-how and/or validate methods and processes.
