(a) 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.

(b) Fuel must have a differential temperature (T) of at least 50F (27C) above fuel dew point temperature and be between 40 to 200F (-40 to 93C).

(c) Fuel pressure must be maintained above engine compressor discharge pressure (Pcd).
