DIESEL POWER
PLANT
INTRODUCTION
A generating station in which internal combustion engine(ICE) or
diesel engine is used as a prime mover for the generation of
electrical energy
Diesel Power Station(also known as Stand-by power station) uses a
diesel engine as prime mover for the generation of electrical energy.
This power station is generally compact and thus can be located
where it is actually required. This kind of power station can be used
to produce limited amounts of electrical energy. In most countries
these power stations are used as emergency supply stations.
Diesel power plants produce power in the range of 2 to 50MW.
INTRODUCTION
They are used as standby sets for continuity of supply such as
hospitals, telephone exchanges, radio stations, cinema theatres and
industries.
They are suitable for mobile power generation and widely used in
railways, submarine and ships.
HOW PETROLEUM DIESEL IS PRODUCED?
Diesel fuel is one of the products created from crude oil. During
the refining process, the viscous dark thick crude oil is turned into the
much lighter diesel fuel.
1.
Crude oil refining starts with heating up the viscous liquid to over
400 degrees Celsius. This process turns the liquid into a vapor. The
vapor then enters a fractional distillation tower. As the vapor rises,
it starts to cool down. The vapor reaches a certain temperature
point and the hydrocarbon chains within it return to a liquid state.
At different levels of the tower are distillation plates that capture
the liquids as they emerge.

2. The longest hydrocarbon chains have a boiling point over 400 degrees
Celsius. As soon as the chains enter the distillation tower, they start turning
into liquid again. This emerges as asphalt or bitumen and exits at the
bottom. As the vapor rises, shorter hydrocarbon chains begin to liquefy.
Fuel oil emerges when the vapor cools down below 370 degrees celsius.
This process continues up the tower, with various distillates emerging as the
vapor cools further.
3. When the vapor reaches between 200 and 350 degrees celsius, diesel fuel
begins to emerge. The vapor collects on the distillation plates where it is
siphoned off into a diesel holding tank.
BRIEF HISTORY
Rudolf Diesel’s Invention
Rudolf Diesel, who is best known for the invention of the engine that bears his
name, was born in Paris, France in 1858. His invention came while the steam
engine was the predominant power source for large industries.
BRIEF HISTORY
In 1885, Diesel set up his first shop in Paris to begin development of a
compression ignition engine. The process would last 13 years.
In the 1890s, he received a number of patents for his invention of an efficient,
slow burning, compression ignition, internal combustion engine.
