Diesel Generator Captive Power Plants
Diesel engine power plants are most frequently used in small power
(captive non-utility) systems. The main reason for their extensive use is the
higher efficiency of the diesel engines compared with gas turbines and small
steam turbines in the output range considered. In applications requiring low
captive power, without much requirement of process steam, the ideal method of power
generation would be by installing diesel generator plants. The fuels burnt in
diesel engines range from light distillates to residual fuel oils. Most
frequently used diesel engine sizes are between the range 4 to 15 MW. For
continuous operation, low speed diesel engine is more cost-effective than high
speed diesel engine.
■ Low
installation cost
■ Short
delivery periods and installation period
■ Higher
efficiency (as high as 43 – 45 %)
■ More
efficient plant performance under part loads
■ Suitable
for different type of fuels such as low sulphur heavy stock and heavy fuel oil
in case of large capacities.
■ Minimum
cooling water requirements,
■ Adopted
with air cooled heat exchanger in areas where water is not available
■ Short
start up time
Diesel Generating system
Diesel engine is the prime mover, which drives an alternator to
produce electrical energy. In
the diesel engine, air is drawn into the cylinder and is
compressed to a high ratio (14:1 to 25:1). During this compression, the air is
heated to a temperature of 700–900°C. A metered quantity of diesel fuel is then
injected into the cylinder, which ignites spontaneously because of the high
temperature. Hence, the diesel engine is also known as compression ignition
(CI) engine.
DG set can be classified according to cycle type as: two stroke
and four stroke. However, the bulk of IC engines use the four stroke cycle. Let
us look at the principle of operation of the
four-stroke diesel engine.
The 4 stroke operations in a diesel engine are: induction stroke,
compression stroke, ignition
and power stroke and exhaust stroke.
1st : Induction stroke - while the inlet valve is open, the descending
piston draws in
fresh air.
2nd : Compression stroke - while the valves are closed, the air is
compressed to a pressure of
up to 25 bar.
3rd : Ignition and power stroke - fuel is injected, while the valves are
closed (fuel injection
actually starts at the end of the previous stroke), the fuel
ignites spontaneously and
the piston is forced downwards by the combustion gases.
4th : Exhaust stroke - the exhaust valve is open and the rising piston
discharges the spent
gases
from the cylinder. Detail Click
