capture.
3 This technology will be of benefit to organizations that work
towards reducing carbon footprint in the industries.
A power cycle scheme utilizing a novel
hydrogen fuel injection concept through
a porous diffuser.
2 Potential for efficiency improvement in addition to resolving the
risk with H
2
combustion in an IGCC process with Distributed Fuel
Injection (DFI).
Hydrogen fired gas turbine with exhaust
gas recirculation (EGR
2 Today’s concepts with hydrogen or syngas fired gas turbine
(IGCC or pre-combustion) require to strongly dilute the fuel with
nitrogen to achieve acceptable NO
x
levels. This process costs 2 - 3
efficient points penalty. By applying high EGR rate, we show that
combustion inherently generates low NO
x
without the need for
dilution, nor complex burner development.
Oxy-combustion with high temperature
ceramic oxygen separation membranes
has been described. The concept is to fully
integrate the air separation unit (ASU)
and the oxy-combustion chamber into a
dense ceramic membrane combustor.
2 The concept has the potential of significant improvement in the
heat integration of the membrane based Air Separation Unit and
improved catalytic flame-less combustion.
Production of powder in small scale of
1-10 kg with equipment that is possible
to scale up.
5-6 The innovation is important for Norwegian industry, institutes and
university since they have the possibility to test production of new
materials for different applications, reducing their cost and risk
compared to larger scale test facilities.
The 3 kW test rig is designed to test
attrition properties of oxygen carrier
particles in dual circulating hot CLC rig.
4 This unique test rig will give valuable information on material
strength on realistic operating conditions.
