Main engine safety trip which trips the main engine when no corrective action is taken to the alarm and in certain cases the main engine is triped manual .

Manual tripping of main engine is done in chance of the collosion or grounding of the ship when sailing in conjusted water and in navigation of the ship in restricted visibility .

So when any main engine trips are activated the Main engine stops and again it should be started with the help of starting air after correcting the faults .

SOME OF THE MAIN ENGINE TRIPS ARE :

1. Over Speed Trip

2. Low Lube oil pressure Trip

3. Cam shaft Lube oil low pressure Trip

4. Jacket cooling water low pressure Trip

5. Piston cooling water low pressure Trip

6. Thrust Bearing High pressure Trip

7. Main Bearing high pressure and temperature Trip.

8. Oil Mist Detector

9. Spring air pressure Low Trip

10. Emergency Manual Trip.

BASIC KNOWLEDGE OF ELECTRICITY

BASIC KNOWLEDGE OF ELECTRICITY

Electric Circuit-a network of paths designed for electric current to carry out a

specified function.

Circuit Breaker - one form of switch providing ON/OFF function and

automatic tripping of the electric circuit in the event of short

circuit or circuit overload. The point at which the breaker

trips depends on the rating of the circuit. The breaker can be

reset to operate again after the fault has been cleared.

Fuse - a conductor, usually in the form of a wire or a cartridge, of low melting

point material placed in the electrical supply circuit and forms part of

the circuit. It serves to protect the electric circuit from short circuiting

or overloading. It melts to interrupt the electricity supply because the

excess current produces a large amount of heat. Unlike the circuit

b r e a k e r, it must be replaced with a new unit after blowing.

Earth Line - a conductor or wire which electrically connects the boiler metal

casing with the earth terminal provided by the electricity supply

c o m p a n y. This line plays a very vital role in the prevention of

electric shock.

Electric Shock - this is a phenomenon whereby the human body has become a

path for electric current. The human body may suffer burns

and heart difficulties which can result in death.

When an electric wire of high potential becomes loose or exposed and is in

contact with the metal casing of the boiler, the casing will also be at a high

potential relative to the earth. If the earth line is also defective, the casing will

be maintained at a high potential. There may not be any indication of the high

potential but when a person is in contact with the casing and he is also in

contact with the earth, an electric path for current is established through the

human body. Potential differences above 50V, A.C. or D.C., are able to drive

electric current through the body. This is what is termed an electric shock.

Alternating current has a more serious effect in that it can cause the victim to

become paralysed while still holding firmly onto the faulty electric part. The

normal mains supply in Hong Kong is nominally 220V A.C. which is well

above the threshold voltage of 50V. However, it should be noted that,

depending on the physical conditions of a person, potential difference less than

this threshold voltage has been known to cause serious injuries.

I M P O RTANT NOTE:- Never try to repair any faulty electric circuit. The

repair should be carried out by a registered.

electrical worker only.

BLOWING OF WATER LEVEL GAUGE of a Boiler,Procedure of blowing through a gauge glass.

A Typical Water Level Gauge

It is a very common design to have all the FIVE cock handles pointing

downwards while the water gauge is in use.

Procedure of blowing:-

When the boiler is in operation, the steam cocks A, D and water cocks B, E are

open and drain cock C is shut.

(a) First shut both steam and water cocks A, D, B and E. Open drain

cock C to prove that all the gauge cocks are in order. Then, with the

drain cock C still open, cocks B and E should be opened. If water

blows out freely from cock C, cocks B and E are clear.

(b) Shut off cocks B and E and open cocks A and D with the drain cock

C still open. If steam blows out freely from cock C, cocks A and D

are clear.

blows out from cock C, then E, A and the water-column are in order.

(d) Close cocks E and A, leaving D, B and C open. If steam blows out

from cock C, then D, B and the water-column are in order.

When any of the cocks are found to be clogged, shutdown the boiler and

overhaul the water level gauge.

Possible causes of gauge glass indicating incorrect level

(a) If cocks A and D or steam passage is shut or choked, boiler pressure

will press the water level in the glass higher than the real water level

of the boiler. The water level indication in glass will, therefore, be

i n c o r r e c t .

(b) If cocks B and E or water passage is shut or choked, steam will

condense on upper column of glass and accumulate. The apparent

water level shown can be higher than the actual water level, causing

false reading.

Water gauge glass should be tested daily at l e a s t at every change of attendant.

The safety of boiler operation relies greatly on proper functioning of the water

gauge glass.

uptake fires in a boiler on board or ships

Soot and unburnt carbon can deposit on the walls of the boiler uptake

(chimney). They form, in effect, another fuel and can catch fire in

the uptake. Although uptake fires do not often occur, they can be

very difficult to extinguish and the hazard builds up quietly and

usually undetected. The fire is caused by smouldering of the deposits

accumulated in the uptake. It usually occurs during boiler shutdown

or under light load condition. There is evidence that under normal

loads the flue gas "cools" the soot and the carbon deposits so that a

smouldering fire does not occur. In the absence of flue gas or if the

flue gas flow is insufficient to cool the deposits, they can catch fire.

When an uptake fire occurs, it results in very high exhaust

temperatures and excessive thick black smoke, mixed with sparks,

coming out of the uptake. The boiler must be shutdown immediately

and the blower switched off or the damper closed to stop any air

supply to the uptake. The fire service must be called. If the uptake is

common for several boilers, all the boilers must be shut down. The

key point is to stop the boiler air supply. No attempt should be made

to extinguish the fire by water unless the water supply is plentiful. A

steam fire may result if the water supply is not plentiful. The fire

should be allowed to die out. The fire must be contained by

restricting and removing any combustibles in the near vicinity.

To prevent an uptake fire, the operator must clean the uptake

periodically to eliminate accumulation of soot and unburnt carbon.

He should also exercise care in the daily operation of the boiler and

maintain the correct air/fuel ratio to ensure complete combustion of

fuel and minimize production of soot or unburnt carbon.

Startup from Cold of a Boiler,The following procedures should be followed when starting a fossilfuel boiler from cold condition

Startup from Cold

The following procedures should be followed when starting a fossilfuel

boiler from cold condition:-

(a) Read and be fully conversant with the detailed operating

instruction for the boiler and its auxiliaries.

( b) Check the Certificate of Fitness (CF) for the boiler to ensure

that it has not expired and that the approved maximum

permissible working pressure (MPWP) is indicated on the

pressure gauge by a red line.

valve.

(d) Open the air vent.

(e) Set the water level gauge valves/cocks to the normal operating

positions (see Appendix III for reference).

(f) Feed water into the boiler as appropriate until the water level

is just below the half-gauge level.

(g) Check that the fuel supply is securely connected and there is

no visual loose connection or fuel leakage.

(h) Set the heating at low firing rate.

(i) Switch on the blower to purge the furnace for the period

recommended by the maker or for at least 15 minutes. The

operator should observe the uptake flap to ensure that a

draught for purging, has been established in the furnace. If

such flap is not provided, the operator should make use of the

particular boiler design to ensure that draught has been

e s t a b l i s h e d .

(j) Switch on the oil fuel pump or the main gas supply and see

that fuel pressure is built up and the oil fuel is circulating (no

circulation is necessary for gas fuel). Confirm that there is no

fuel leakage. If there is any leakage, shut down the boiler and

arrange the repair before proceeding.

(k) Now the boiler ignition system may be switched to establish a

flame inside the furnace, for raising steam at a low firing rate.

The operator may choose to a use continuous firing method or

intermittent firing method depending on the design and the

past operating experience of the boiler. Intermittent firing is

safer but takes a longer time to raise steam. In many practices,

intermittent firing is typically 10 minutes fire in every 20

minutes, until steam is generated.

(l) If the ignition fails, repeat from step (i). However, if it fails to

ignite for several times, stop the fuel supply and purge the

furnace for the period recommended by the maker or for at

least 10 minutes. Examine the burner, the flame detector and

the fuel system such as fuel quality (e.g. is there water

contamination in the oil fuel). When everything is found in

o r d e r, repeat from step (i).

(m) The boiler should be heated gradually to raise steam. After

steam has been coming out from the air vent for 3-5 minutes,

shut the air vent. This waiting period is to ensure that all air

trapped inside the boiler has been driven out.

(n) The boiler may now be switched to high firing rate to bring the

steam pressure to the working pressure which shall be less

than the MPWP.

(o) Blow the water level gauge (see Appendix III for blowing

procedures) to see that the gauge is in proper working order.

(p) When the steam pressure has reached the working pressure,

open the steam outlet stop valve gradually and cautiously. If

hammering or any abnormal noise is heard along the steam

pipeline, do not open the stop valve any further. Instead, the

stop valve should be closed to a 'cracked open' position (about

1/2 turn open) to warm the pipeline. If possible, the pipeline

should be drained during this procedure. After warming the

pipeline for a few minutes, the stop valve can be opened

gradually and cautiously again until fully opened.

(q) The steam outlet stop valve should be fully open at all times

during operation. Do not throttle the stop valve.

Fuel Burning Installation in a boiler, Flame Detection

Fuel Burning Installation

The fuel burning installation consists of an air blower, a burner

and fuel supply. The air blower supplies air for combustion and

p u rging before and after any combustion. The burner atomizes the

oil fuel for ease of ignition and good combustion. The burner, or

more exactly nozzle, in a gas fired boiler does not atomize the gas

but provides a cone of flame of the designed length and angle for

optimum combustion.

Flame Detection

A burner-control system must incorporate means of assuring the

presence or absence of flame on each individual burner regardless

of the type of fuel being burned. Ultraviolet (UV) flame detectors

have been successfully applied for all types of fuels. Flame

monitoring devices in current use are designed for on-off type of

operation based on the presence or absence of the flame. Some

plants today are using closed-circuit television to provide a means

of continuous furnace observation by the control room, and more

applications are expected in future.
