1. Main structure of the natural gas generator setNatural gas
generator sets include natural gas-fueled reciprocating internal
combustion engines, alternators, electrical parts, control devices,
cooling systems, lubrication systems, exhaust systems, fuel
systems, and auxiliary equipment. Except for the exhaust pipe and
silencer of the exhaust system, they are mounted on a steel
chassis. The generator set is a fixed permanent installed
generator set. The steel underframe is mounted to the concrete
foundation.2. Main structure of the biogas engineThe gas fuel of
this engine series can be natural gas, biogas, syngas, coal mine
gas, and etc. In order to meet the requirements of different
customers, this gas engine can be packaged into generating set or
other power take-off.3. AlternatorThe brushless constant-voltage
synchronous alternators are of the self-excited type with an
electronic voltage regulator integrated in the excitation system.
They are used as main or standby units in land based power
installations and for ships' electrical systems and can be driven
by internal combustion engines or gas, steam and water turbines and
electric motors.Structure: The alternator comprises the main
machine exciter and excitation system. The main machine is of
revolving magnetic field with cylindrical rotor and damper winding.
The exciter is revolving armature machine. The exciter power is
supplied to the rotor of the main machine via rotating
rectifiers.4. Genset control panelDedicated gas genset control
panel is in the shape of cabinet. With controller, various
indicating instruments, regulating buttons, protection indicators,
emergency shut-down button installing inside to monitor the working
status of the genset. Speed regulation is executed by the
electronic governor and the fine regulation can also can be done by
the buttons on the control panel. The voltage of the genset is
automatic through the buttons on the control panel.5. Parameter
