50kW class micro gas turbine set in FREA
The gas turbine facility
50kW class micro gas turbine firing kerosene was
remodeled for power generation firing ammonia.
A standard combustor is replaced with a prototype
combustor which enables a bi-fuel supply of
kerosene and ammonia gas.
Diffusion combustion is employed to the prototype
combustor due to its flame stability.

Summary
• 50kW class micro gas turbine firing kerosene was remodeled for power
generation firing ammonia.
• A standard combustor is replaced with a prototype combustor which enables
a bi-fuel supply of kerosene and ammonia gas.
• Diffusion combustion is employed to the prototype combustor due to its flame
stability.
• Demonstration test of co-firing of kerosene and ammonia gas was achieved to
check the functionality of the each component of the micro gas turbine.
• The gas turbine started firing kerosene and increased its electric power
output.
• After achievement of stable power output, ammonia gas was started to be
supplied and its flow rate increased gradually.
• Over 25kW power generation was achieved by supplying about 10% heat
from ammonia gas in HHV.
• 21kW power generation was achieved by supplying about 30% heat from
ammonia gas in HHV.
