BOILER GAUGE GLASS BLOW THROUGH

 GAUGE GLASS BLOW THROUGH

• SHUT THE STEAM SIDE VALVE 
• SHUT THE WATER SIDE VALVE 
• NOW OPEN THE DRAIN VALVE 
• NOW GAUGE GLASS BECOME EMPTY.
• NOW OPEN THE STEAM SIDE VALVE ,IF STEAM COME OUT WITHOUT ANY DEFICIENCY WHICH MEANS STEAM SIDE IS CLEAR .
• NOW CLOSE THE STEAM SIDE 
• OPEN THE WATER SIDE, IF WATER  WILL COME OUT WITHOUT ANY DEFICIENCY WHICH MEANS  WATER SIDE IS CLEAR.
• NOW CLOSE THE WATER SIDE 
• AND CLOSE THE DRAIN VALVE.
• NOW OPEN THE WATER SIDE FIRST, WATER WILL RISE AND FILL UP THE GAUGE GLASS.
• NOW OPEN THE STEAM SIDE STEAM WILL COME INTO GAUGE GLASS AND SHOW THE EXTRACT LEVEL OF INSIDE  BOILER WATER.

Notes

SURVIVER MAY ASK YOU OPEN WATER SIDE FIRST 

(If we open steam side first gauge glass will breake because of lantern heat.)

2/S Cross-Head Engines Vs 4/S Trunk Piston Engines

 

STARTING OF IG SYSTEM& IG PLANT PARTS AND FUNCTIONS

 Starting of IG System

• Boiler should be on.
• Set the line for deck seal pump 
• Set the line for scrubber pump
• Set the line for O2 analyser.
• Set the line on blower,
• Now put the breaker to on position.
•  Ig starts & running.

Function of ig parts.

Scrubber tower:

• Gas will be cooled down to working temperature.
• Solid particles will removed 
• Soluble gas and Sox and carbon gases set mixed with water and draun out.

Demister 

•  Demister made on wire gauge.
• Act as a water absorbent.
• It Moisture will removed and gas will br dry.

Blower

• There will be two blower .
• One for stand by another one will send the gas freeing to cargo tank.

Pressure regulator valve 

• It regulates ig pressure asper discharge rate of cargo and maintain always  positive pressure inside the tank.

O2 analyser.

• It will analyse the oxygen content flowing with gas 

Temperature recorder.

• If ig gas above 57°c it will not allow the gas to cargo tank.

Bleed valve 

• Its a three way valve  .if o2 content is High in ig gas it will open the valve send the gas to atmosphere.

Deck seal.

• It is a non return valve.which will not alow the gas back.

Non return valve.

• Secondary valve . preventive the back flow of gas.

Pv valve

• Safety fitted in the tank to prevent the exclusive vacuum and pressure build-up in the cargo tank it will release the pressure to atmosphere.

Pv breaker.

• Which is fitted in common ig line. When suddenly increase of vacuum and pressure it will open and release the pressure and vaccum.

Mast valve 

• Common ventilating system for cargo tanks . While loading and unloading it should be open.

Deck isolation valve.

• It will isolates the ig line from ig plant.

Vapour line 

• To receive shore supply of ig gass 
• To discharge ig gas to shore storage tank

PORTABLE FIRE EXTINGUISHER MECHANICAL FOAM

MECHANICAL FOAM

• used for classA and ClassB fires
• 74g of co2 cartage will be used @36 bar pressure
• 97% of water and 3% of AFF ( aqueous Film forming foam)
• Duration 60sec 
• length of flow 6meter
• AFF contain- surfactant such as sodium alkyl sulfate, fluoro surfactant such as fluoro telecom atomic  acid.

Safeties

• Safety pin
• Relief valve

PORTABLE EXTINGUISHERS WATER TYPE FIRE EXTINGUISHER

 WATER TYPE FIRE EXTINGUISHER

• Used for classA and ClassB fires like (wood, paper)
• Should use Minimum 9 to maximum 13.5 lit capacity of water as per the solas regulation.
• 74g of cg cartage should be used 
• Duration 60 seconds lenth of the 6 meter 
• Pressure will difference as per the capacity and weight of the cylinder.

Safeties

• Relief hole, and safety pin 

Maintenance

• Weekly:
• Check and clean the nozzle and seal.

• Monthly:
• Check internal and external 
• And co2 cartage and safety pin and weight

• Yearly
• Pressure test @ 36 bar
