Generators need no introduction as
an integral part of power production and back-up systems. Be it for industry,
offices, hospitals, hotels, homes, scientific research laboratories, ships or
military establishments – generators have a crucial role to play for their
smooth and uninterrupted operations.
The range of capabilities and
features associated with generators may vary from case to case, although there
are a few standard manufacturing practices to meet the widely disparate range
of requirements. One cannot expect that a generator for a restaurant will be
similar in size to that of a generator used in a gigantic cargo carrier.
However, generators need fuel so
that the basic operating principle of converting mechanical energy to
electrical energy can be carried out. Every generator has an engine, attached
with which is a rotor. The engine produces rotational movement for the rotor,
which works in coordination with the stator by obeying the principles of electromagnetic
induction. This is fairly complicated process but has been sort of
oversimplified in this post for the sake of the non-technical readers.
Now, to run the engine, some sort of
fuel is necessary. In fact, the basic requirement of any generator is the fuel
itself. The engine design, output characteristics and a host of other technical
matters are intricately related to the choice of the fuel. It would not be an
exaggeration to say that the longevity and resale value of generators are also dependent
on the choice of fuel that powers the engine, because the fuel itself
determines the other aspects.
Coming to the popularity of diesel
as the favorite choice for fuel, there are several factors that make it the
best choice. The reasons are stated below:
·
Availability: Diesel is widely available across
all parts of the world, as it has been a primary choice for automotives,
especially the heavy ones like buses, trucks, trains, etc. There are also a
major portion of the existing cars that run on diesel. Therefore, the supply
chain of diesel is quite strong, and this ensures that it will be available
readily.
·
Price: The price of diesel is low as
compared to other fuel varieties, mainly due to the large usage of diesel as an
automotive fuel for the major period of the automotive history. Besides, diesel
being less refined than gas makes it a bit less costlier, as the cost of
refining doesn’t add up to a great extent.
·
Physical properties: Diesel has low freezing point and
greater viscosity as compared to gas. This makes the transportation of diesel
through pipelines easier than gas, especially through difficult terrains and
cold climates where temperatures hover around zero degree. Most importantly, it
also has a bit higher ignition temperature as compared to gas, which means that
it is not as dangerously inflammable as that of gas. Also, it doesn’t evaporate
easily.
·
Design and Cost: Diesel makes the design of engine
must simpler. This makes the engines of Diesel
Generators more robust, adding to the longevity of the generator
engines. Quite naturally, Used
Diesel Generators usually claim high resale value as compared to their
gas counterparts.
