Corrosion in fuel conditioning system components can shorten equipment lifetimes, reduce
reliability, and increase the risk of sending out-of-specification fuel to the microturbine. Similarly,
higher-than-allowable hydrogen sulfide levels in the microturbine can cause premature failure of
fuel system components, injectors, combustion liners, and, if allowed to progress too long,
catastrophic engine failure and fire risk.
Project developers should be aware that any hydrogen sulfide in the fuel will be combusted to
form sulfur dioxides in the exhaust, which in many parts of the world are regulated as polluting
emissions. Contact your local air quality regulating body for more information.
Hydrogen sulfide is an extremely dangerous gas and toxic to humans even at low concentrations.
Special care and training are necessary when dealing with fuels containing hydrogen sulfide.
6.5.6. Heat Tracing
The fuel conditioning system cannot always be located near the microturbines. For long pipe runs,
heat tracing and insulation may be necessary to maintain dew point suppression. Heat tracing is
an electric heating cable designed specifically for this purpose. Consider wrapping heat tracing
around larger components such as valves, regulators, and filters so that the large thermal capacity
of the metal does not cause local cooling of the fuel stream.
Sunlight and ambient air convection can help heat the fuel piping, but this is not a reliable method.
Pipe insulation is generally added to minimize heat loss during colder seasons which limits
contributions from these sources.
6.5.7. Piping
Fuel delivery piping should be installed by a trained professional. The piping must be rated for
the appropriate pressure and temperature, and the piping material must be compatible with all
components found in the fuel.
The following considerations should be taken for all microturbine fuel delivery piping systems. In
all cases local piping codes must be followed.
 Make sure all fuel connections are tight, leak free, and protected from physical stress.
 Fuel lines must be routed with no kinks or sharp bends.
 Adequate support and protection must be provided for all piping, per local codes.
 Make sure that the piping supplying the unit is well-protected from foot and equipment
traffic.
 Flexible fuel lines may have code restrictions on length, location of service, protection,
pressure, fuel type, end fitting type, and material.
 PVC fuel lines may not be allowed depending on local codes and fuel type.
 The use of existing pipe in a building may be permitted, but it may be necessary to perform
pressurized leak checks with pressures that are higher than the normal service pressure.
 Fuel system must be designed to handle at least 1.5x the maximum operating pressure of
the system. All piping and components must be rated higher than this pressure and the
system should be pressure tested prior to microturbine commissioning. All piping systems
should be protected from overpressure events.
