Notes:
(a) The gas fuel system is designed to operate with fuels that comply with Solar’s Engineering
Specification ES 9-98. Most commercially available natural gas fuels comply with ES 9-98.
The gas fuel system can be modified to operate with fuels that do not comply with ES 9-98.
Solar gas turbines can operate on low Btu fuels. Please contact Solar Turbines for
assistance in evaluating fuel characteristics and gas turbine requirements.
(b) Fuel pressure and flow requirements can be affected by several factors such as: fuel
temperature, fuel lower heating value, air inlet temperature, fuel composition, fuel specific
gravity, engine injector type, inlet duct loss, relative humidity, site elevation, and piping length
and diameter. Based on site conditions, minimum fuel pressure and flow requirements may
be less than stated values. Please contact Solar Turbines for site-specific fuel pressure and
flow requirements.
(c) Fuel must have a differential temperature (ΔT) of at least 27°C (50°F) above fuel dew point
temperature.
(d) The particle size in the air stream should not exceed 10μ. Since it is impractical to remove
100% of all particles larger than 10μ, this is defined as ß10 > 100, or 99% efficient. Oil or
hydrocarbon content should not exceed 1 ppm. The dew point at line pressure shall be at
least 6°C (10°F) below the minimum temperature to which any part of the air system is
exposed or between -29°C and 93°C (-20°F and 200°F). Air should be free of all corrosive
contaminants, hazardous gases, flammables, and toxics.
