INTRODUCTION

In a diesel power station, diesel engine is used as the prime mover. The diesel burns

inside the engine and the products of this combustion act as the working fluid to

produce mechanical energy. The diesel engine drives alternator which converts

mechanical energy into electrical energy. As the generation cost is considerable due to

high price of diesel, therefore, such power stations are only used to produce small

power.

Although steam power stations and hydro-electric plants are invariably used to generate

bulk power at cheaper costs, yet diesel power stations are finding favour at places

where demand of power is less, sufficient quantity of coal and water is not available and

the transportation facilities are inadequate. This plants are also standby sets for

continuity of supply to important points such as hospitals, radio stations, cinema houses

and telephone exchanges. Power Plant Design / MEP544D2

The diesel engine is recognized as the most promising powertrain in the foreseeable

future due to its superior thermal efficiency and reliability. The diesel engine has been widely used in commercial vehicles, industrial applications and today’s passenger cars

and light-duty trucks.

A diesel engine is a type of compression-ignition engine using diesel fuel. Diesel

engines can be classified into various categories. Understanding the differences and the

unique characteristics of each category of diesel engines is important for diesel engine

system design.

HISTORY The first man, who had invented the engine with ignition from compression, was E. Steward. He was interested in engines, what can work without spark plugs. In Steward’s

engine the air was compressed and compressed air was blown into the combustion

Power Plant Design / MEP544D2

4 Power Plant Design for Sagay, Camiguin chamber. Unfortunately, Steward had not come into mind to test the efficiency of that

type of engines.

Developing the concept of “economy-type heat-engine”, Rudolph Diesel in 1890

invented the engine much more efficient due to high compression ratio. In his book he suggested to use the powdered coal, but it was difficult in real life – the coal dust has an

abrasive properties and it should be found the way to put it somehow in combustion

chamber. So it was suggested to use the tailing that remains after oil refining in such

engines. So in 1897 Diesel had patented the engine design, later named Diesel engine.

Rudolf Diesel was born in Paris in 1858. His parents were Bavarian immigrants. Rudolf

Diesel was educated at Munich Polytechnic. After graduation he was employed as a

refrigerator engineer. However, he true love lay in engine design. Rudolf Diesel

designed many heat engines, including a solar-powered air engine. In 1893, he

published a paper describing an engine with combustion within a cylinder, the internal

Power Plant Design / MEP544D2

5 Power Plant Design for Sagay, Camiguin combustion engine. In 1894, he filed for a patent for his new invention, dubbed the

diesel engine. Rudolf Diesel was almost killed by his engine when it exploded. However,

his engine was the first that proved that fuel could be ignited without a spark. He

operated his first successful engine in 1897.

POWER PLANT DESIGN FOR SAGAY Diesel Power Plant for Sagay, Camiguin produces power in the range of 6.4 MW.

And they are used standby sets for continuity of supply such as hospitals, cinema

theatres and industries.

ADVANTAGES OF A DIESEL ENGINE  More efficient and economical to use.  Fuel vapor is not explosive.  Exhaust gases are less poisonous – less carbon monoxide.  Greater lugging power and torque. Power Plant Design / MEP544D2

6 Power Plant Design for Sagay, Camiguin  Engines are durable and if properly cared for will maintain their economy.  Fuel is less volatile – no vapor lock problems  Can use a variety of fuels and mixtures.

DISADVANTAGES OF DIESEL ENGINE  The fuel in diesel engine is ignited by the heat of the compressed air.  HPFP of diesel engine is extremely unreliable unit.  The exhaust filter is warming up in the flow of exhaust gas.  it is expensive  Noise and vibration till the latest times could not be separated from the words “Diesel engine”.

ADVANTAGES OF DIESEL POWER PLANT  The design and layout of the plant are quite simple.  It occupies less space as the number and size of the auxiliaries is small.  It can be located at any place.  It can be started quickly and it can pickup load in a short time.  There are no standby losses.

DISADVANTAGES OF DIESEL POWER PLANT  The plant has high running charges as the fuel (diesel) used is costly.  The plant doesn’t work satisfactorily under overload conditions for a longer

period.  The plant can only generate small power.  The cost of lubrication is generally high.  The maintenances charges are generally high.

WHY WE CHOOSE DIESEL POWER PLANT

Purpose

 Diesel power plants produce energy though the combustion of chemical fuel, in

most cases diesel derived from petroleum, into mechanical energy. This energy

is then used to power an alternator which in turn generates electricity. Diesel is

preferred to other fuel types as these engines have a higher thermal efficiency

than other commercial generators of equivalent size.

Process

 Most modern generators harness mechanical energy through the process of

electromagnetic induction. In this system, the mechanical energy produced by

the diesel engine moves an electrical conductor, such as a magnetically charged

wire, in a magnetic field. The movement of the conductor creates a difference in

voltage between the two ends of the charged wire, creating a flow of electric

charges and thereby generating electricity.

ESSENTIAL ELEMENTS OF DIESEL POWER PLANT

I.

DIESEL ENGINE

 Diesel engine is a compressor ignition (CI) engine.  The two – stroke cycle engine is more favored for diesel power plants.  The air required for the diesel engine is drawn through the air filter form the

atmosphere and compressed inside the cylinder.  The fuel (diesel) from the diesel engine is drawn though a filter from the all-day

tank and injected into the cylinder through fuel injector.  Because of the high temperature and pressure of the compressed air, the fuel

burns and the burn gases expand to do work on the moving part inside the

cylinder called piston.  This movement of the piston rotates a flywheel and the engine is directly couple

to electric generator.  The gases after expansion inside the cylinder are exhaust into the atmosphere

and passes through a silencer in order to reduce the noise.

Power Plant Design / MEP544D2

11 Power Plant Design for Sagay, Camiguin

II.

STARTING SYSTEM

 The starting motor will crank the engine. The starting motor will spin the engine at a high enough rpm to allow the engine’s compression to ignite the fuel and start

the engine running.  The engine will then accelerate to idle speed. When the starter motor is

overdriven by the running motor it will disengage the flywheel.

III.

FUEL SUPPLY SYSTEM

 It consists of storage tank, strainers, fuel transfer pump and all day fuel tank. The

fuel oil is supplied at the plant site by rail or road. The oil is stored in the storage

tank. From the storage tank, oil is pumped to smaller all day tank at daily or short

intervals. From this tank, fuel oil is passed through strainers to remove

suspended impurities. The clean oil is injected into the engine by fuel injection

pump.

Power Plant Design / MEP544D2

12 Power Plant Design for Sagay, Camiguin

IV.

AIR INTAKE SYSTEM

 This system supplies necessary air to the engine for fuel combustion. It consists

of pipes for the supply of fresh air to the engine manifold. Filters are provided to

remove dust particles from air which may act as abrasive in the engine cylinder.

V.

EXHAUST SYSTEM

 This system leads the engine exhaust gas outside the building and discharges it

into atmosphere. A silencer is usually incorporated in the system to reduce the

noise level.

VI.

COOLING SYSTEM

 The temperature of the burning fuel inside the engine cylinder is in the order of 15000 0C to 20000 0C. In order to lower this temperature water is circulated

around the engine.

Power Plant Design / MEP544D2

13 Power Plant Design for Sagay, Camiguin  The water envelopes (water jacket) the engine. The heat from the cylinder,

piston, combustion chamber etc., is carried by the circulating water.  The hot water leaving the jacket is passed through the heat exchanger.  The heat from the heat exchanger is carried away by the raw water circulated

through the heat exchanger and is cooled in the cooling tower.

VII.

LUBRICATING SYSTEM

 The system minimises the wear of rubbing surfaces of the engine. It comprises of

lubricating oil tank, pump, filter and oil cooler. The lubrication oil is drawn from

the lubricating oil tank by the pump and is passed through filter to remove

impurities.
