The Operation of
Natural Gas Air Compressors
The gas engine changes the chemical
energy from natural gas and turns it into mechanical work. The engine
system operates efficiently due to the heat recovery. Usable heat can be
recovered from the jacket water and the exhaust. Hot water can be
produced from the heat from the jacket water. Hot water or low pressure
steam can be produced from the heat taken from the exhaust.
With the air/fuel system natural gas engines have the capability to be
naturally aspirated or turbocharged.
Air is drawn into the engine at atmospheric pressure in the natural
aspirated engines. With turbocharged engines, the intake air is
compressed when the exhaust drives a small turbofan to compress the
intake air. With this particular function, more molecules can be
squeezed into the cylinder when the air fuel mixture is compressed by
the turbofan. More energy is discharged as the mixture is ignited.
Therefore, an engine that is turbocharged has the ability to provide
more shaft work than does a naturally aspirated engine of the same size.
In order to remove heat from compressed air, there must be a heat
exchanger with the turbocharger positioned after the compressor fan. The
density must be increased to cool the compressed air. In order to
accomplish this, the oxygen content for a particular volume of air must
be increased, then more fuel can be burned.
The main advantage of a turbocharged engine with an intercooler over
that of a naturally aspirated engine of the same or similar size is that
approximately 35% more work can be accomplished.
