Brief Description of the Plant Giral Lignite Power Limited is
situated about 12Kms from village Bhadka at Barmer-Jaisalmer
National Highway. Total installed capacity of the plant is 2x125
MW.The principal raw material is lignite and
light diesel oil and furnance oil is also used to start & to
maintain temperature as and when required. 1- Process Involved in
Power Generation:- Lignite having 6% sulphur from near by RSMM
mines are
unloaded at stock pile area through dumpers. The lignite is
crushed in crusher and is transported
through conveyer belt to lignite bunkers from which lignite is
feed in to combustor. This lignite with the
help of air supplied through PA &SA fans, is burn in the
combustor in which temperature of 800-850oC is
being maintained during the operation of the unit.
This is circulating fluidized bed combustion (CFBC) based
technology wherein large portion
of flue gases with heavy particles are returned beck to
combustor with the help of 2 nos of cyclones. The
combustor is having sufficient quantity of bed material, which
is being fluidized with the help of the
primary air, which helps in combustion of lignite and flue gases
from the furnace are extracted by
induced draft fan which maintains balance draft in the furnace.
These flue gases emits their heat energy
to water tubes located in combustor, and in the second pass and
finally passes through air pre heater
and goes to electro static precipitator where the ash particles
are extracted. Electro-Static Precipitator
consists of metal plates which are electrically charged. Ash
particles are attracted on to these plates, so
that they do not pass through the chimney to pollute the
atmosphere. Regular mechanical hammers
blows cause the accumuled of ash to fall to the bottom of the
precipitator where they are collected in a
hopper for disposal.
2- STEAM TO POWER:- A steam pipe conveyers steam to the turbine
through a stop valve (Which can be used to shut off steam in
emergency ) and through control valve that automatically regulate
the supply of
steam to the turbine. Stop valve and control valves are located
in a steam chest and a governor driven,
shaft operates the control valves to regulate the amount of
steam used. (This depends upon the speed
of the turbine and the amount of electricity required from the
generator).
Steam from the control valve enter the high pressure cylinder of
the turbine, where it passes
through a ring of stationary blades fixed to the cylinder wall.
These act as nozzle and direct the steam in
to a second ring of moving blades mounted on a disc secured to
the turbine shaft. This second ring turn
the shaft as a result of the steam. The stationary and moving
blades together constitute a Stage of the
turbine and in practice many stages are necessary, so that the
cylinder contains a number of ring of
stationary blades with ring of moving blades arranged between
them.
The steam passes through each stage in turn until it reaches the
end of the high pressure
cylinder and in its passage some of its heat energy is changed
into mechanical energy.
The steam leaving the high pressure cylinder goes back to the
boiler for reheating and returns
by a further pipe to the intermediate pressure cylinder. Here it
passes through another series of
stationary and moving blades.
Finally the steam is taken to the low pressure cylinder, in
which it enters at the center flowing
-
8
outwards in opposite directions through the rows of turbine
blades (An arrangement known as double
flow) to the extremities of the cylinders. As the steams give up
its heat energy to drive the turbine its
temp., and pressure fall and it expands. Because of this
expansion the blades are much large and longer
towards the low pressure end of the turbine.
The turbine shaft usually rotates at 3000 RPM (Revolution Per
Minutes).This speed is
determined by the frequency of the electrical system used in the
country and is the speed at which a-2-
polegenerator must be driven to generate alternate current at a
frequency of 50 cycle per second.
When as much energy as possible has been extended from the steam
it is exhausted directly to
the condenser. Cold water is circulated through these tubes and
as the steam from the turbine passes
round them it is rapidly condensed into water
(Condensate).Because water has a much smaller
comparative volume then steam, a vacuum is created in the
condenser. This allow the steam to reduce
down to pressure below that of the normal atmosphere and more
energy can be utilized.
From the condenser, the condensate is pumped through low
pressure heaters by the extraction
pump, after which its pressure is raised to boiler pressure by
the boiler feed pump. It is passed through
further feed heater to the economizer and the boiler
reconversion into steam
3- SWITCHING AND TRSANSMISSION. The electricity is usually
produced in the stator winding of large modern generator at 11000V
and is fed through terminal connections to on side of a
generator
transformer that steps up to the voltage to 220000 volts. From
here conductors carry it to a series of
there switches comprising as isolator, a circuit breaker and
another isolator. The circuit-breaker, which is
a heavy duty switch capable of operating in a fraction of a
second, is used to switch of the current
flowing to the transmission lines. Once the current has been
interrupted the isolators can be opened.
These isolate the circuit-breaker from all out-side electrical
sources, so that there is no chance of any
high voltage being applied to its terminals. Maintenance or
repair work can then be carried out in safety. Circuit-breaker work
like combined switches and fuses but they have certain special
features and are very different from the domestic switch and fuse.
When electrical current is switched off by separating two contacts
an arc is created between them. At the voltage used in the home the
arc is very small and only lasts for a fraction of a second but at
the high voltages used for transmission, the size and power of the
arc is considerable and it must be quickly quenched to prevent
damage. One type of circuit-breaker has its contact immersed in
insulating oil so that when the switch
is opened, either by powerful electrical coils or mechanically
by springs the arc is quickly extinguished by
the oil. Another type works by compressed air which operate the
switch and at same time blow-out the
arc.
Three wires are used in a Three Phase system for large power
transmission as it is
cheaper than the two wire Single Phase system that supplies the
home.
The center of the power station is the control room. Here
Engineers monitor the out put of
electricity, supervising and controlling the operation of
generating plant and high voltage switch gear
and directing power to the grid system as required. Instruments
on the control panels show the out put
and conditions which exists on all the main plant and a
miniature diagram indicate precise state of the
electrical system.

Hazards and Medical Management
Chlorine
Hydro Chloric Acid
Caustic Soda
SULPHURIC ACID Hazards and Medical Management
CHLORINE
TOXICITY Chlorine is corrosive. It reacts with body moisture to
form corrosive acids. Chlorine gas is primarily a respiratory
irritant. Concentration above 3 to 5 ppm by volume in air is
readily detectable by a normal person. Inhalation of chlorine may
cause respiratory injury.
ACUTE EFFECT The first symptom of exposure to chlorine is
irritation to the mucous membranes of eyes, nose and throat which
increase to smarting and burning rain. Irritations spread to the
chest. A reflex cough develop which may be intense and often
associated with pain behind the breastbone. The cough may lead to
vomiting. If the duration of exposure or the concentration of
chlorine is excessive, it will cause restlessness, throat
irritation, sneezing and copious salvation. In extreme cases, lung
tissues may be attected resulting in pulmonary edema, full of blood
pressure.
EFFECT OF CHLORINE AT VARIOUS CONCENTRATIONS
Chlorine concentration in air (PPM)
Effects
0.2 0.5 No toxious long term effect. 0.5 Slight odour. 1.0 3.0
Definite odour, irritation to eyes and nose. 6.0 Irritation of the
throat. 30.0 Intense cough fits. 40.0 60.0 Exposure without
effective respirator for 30 to 60 Minutes or
more may cause serious damage. 100 May cause lethal damage.
10000 Danger to life even after few deep inhalations.
CHROINIA EFFECT: Prolonged exposure to concentration more then 5
ppm may result into bronchial problems. Due to long exposure to
chlorine, affected persons may get Acne.

Call a physician immediately. 5. As the victim begins to breathe
un-aided or to move lay him down with his body raised and
continuous to
administer oxygen. 6. The physician will keep the victim under
medical supervision for microbial infection may be caused. Therapy
for specific physiological disturbance- for the guidance and
attention of medical profession:-
Pulmonary Edema 1 Administer 60 to 100% _ Oxygen at 6 ltr. /
min. 2. Intermittent positive pressure breathing apparatus set to
deliver positive pressure 5-15 cm. of water in the
respiratory cycle, is valuable in reducing the formation of
edema. 3. Steroid therapy, given early is effective is preventing
or alleviating pulmonary edema. There is chlorine
intoxication. 4. The use of diuretics and antibiotics should be
considered to reduce adoma and protection against
secondary pulmonary infection.
BRONCHOSPASM 1. There is no known antidote for chlorine
exposure. The exposure is associated with acute symptomatology
requiring supporting therapy only. Early treatment is the most
effective. 2. Broncho- dilators nebulizer into the intermittent
positive pressure gas stream are often beneficial. 3. Two effective
drugs are: ISSOPROTERENOL HYDROCHLORIDE CYDO PENTEMIME
HYDROCHLORIDE The comm. Only employed single treatment dosage for
each drug is 0.3 cc This may be altered according to clinical
needs.

PERSONAL PROTECTION EQUIPMENT. 1. Introduction. In industry when
a potential hazard gets out of hand and may affect the safety of
people who are in its ranges, suitable protective devices are
required to be used. The personal protection equipments do not
eliminate a hazard however these devices are designed to interpose
an effective barrier between a person and harmful objects sustance
of radiation. When we deal with chlorine and ammonia one may expose
to hazards which can be harmful to his respirating tract and other
body parts.
2. Requirement of P.P.E:- Suitably of PPE can be listed as
under:-
1. Adequate protection against the hazards to which the works
will be exposed. 2. Maximum comfort and minimum capability with
protective efficiency 3. No restriction in essential.
3. TYPE OF PROTECTIVE EQUIPMENTS:- Personal protective
equipments are classified as under:-
Respiratory protective equipments. This appliances can further
be classified in two classes:-
1- Air Purifying type. 2- Supplied Air Type.
1- Air Purifying type. In this type of appliance according to
the degree of respiratory hazard, that is, the concentrations of
the toxic gas present one may opt for either CARTRIDGE TYPE GAS
MASK or CANISTER TYPE GAS MASK. The cartridge or canister are
filled with appropriate chemicals to be used in a particular gas.
When the chemical exhausts Cartridge/Canister should be replaced
with a fresh one.
2- Supplied Air type. In this type these equipments are covered
which are capable of providing respiratory protection in any
concentration of contaminant gas as these equipments have their own
source of breathable air hence isolate the user from the
contaminated atmosphere. To accomplish it, either the air source (a
compressed air cylinder) remain with the user in that case it is
known as SELF CONTAINED BREATHING APPRATUSor the breathable air is
supplied from plants service air-line/ big air-cylinder/manual or
electrical air blower through a tube and mask.
NON RESPIRATORY PROTECTIVE EQUIPMENTS. In this class these
equipments are covered whether provide protection on the body as a
whole or in part. The details are given below:-
1- SAFETY HELMETS: - Safety helmets are used for protection of
head against fall of corrosive / toxic liquids and hard objects.
These are made from thermoplastic material.
2- SAFETY GOGLES:- Safety goggles are used for protection of
eyes against splash of corrosive/ toxic liquids. These are made
having one piece rubber / plastic molded frame and toughened
visor.
3- FACE SHIELD:- Face shield protects the face of the user
against splash of corrosive /toxic liquids. It is
available in 6, 9 and 12 with head band.
-
48
4- PVC APRON:- PVC apron/ suit protect the users body against
the splash of corrosive/ toxic liquids. These are also available in
rubber or leather. A coating of fabric or reinforcement is also
available with synthetic rubber.
5- HAND GLOVES & GUM BOOTS:-Hand gloves and gum boots
protect the hand & feet of the user against corrosive /toxic
liquids. Gloves are available in leather to handle sharp
objects.
6- FIRE ALLUMINISED SUIT:- This suit is made of alumished
asbestos, its function is to enable a man to go near a fire and
work and to enter into flame for short duration of time. Its
temperature range is 1300oF for 5 to10 minutes and 1000oF for 20
minutes.
