1. A hydraulic fracturing system, comprising:
a fracturing equipment comprising a turbine engine fueled by natural gas or diesel as a power source, an exhaust duct, and a plunger pump assembly;
wherein:
the plunger pump assembly comprises a plunger pump and a reduction gearbox integrated with the plunger pump; and
an exhaust end of the turbine engine is connected to the exhaust duct whereas an output driving end of the turbine engine is connected to the plunger pump assembly by a direct coupling without a transmission shaft between the reduction gear box integrated with the plunger pump and the output driving end of the turbine engine.
