Kettle and its Accessories

  Definition of Kettle :-

•  A Kettle is an enclosed volume in which a chemical reaction takes place.
• MOC of Kettle:

1. SS
2. MS
3. MSGL 
4.  HDPE
5. FRSVE
6. Hetron

Body of Kettle

 Its is mainly hemispherical dish end cylinder with limpet or jacket around it.

 

Accessories on Kettle

1. Motor

2. Gear Box

3. Lantle assembly

4. Mechanical seal/Gland filling

5. Thermo well

6. Level transmitter

7. Agitator

8. Baffles

9. Flush bottom valve

10. Dip pipe or Diverter 

1.Motor

• Its is use for driving Agitator in Kettle as it convert electrical energy to mechanical.

• Mainly Motor of All kettle are Having 1440 RPM , but some time as per requirement we use 2900 RPM motor

• Depend on Zone of classification we use FLP or Non FLP motor.

• Some motor shaft have gear mounted and some having pulley .

2.Gear Box

• Mainly use for reducing speed of agitator from speed of motor.

• Gear ratio is depend on application and process requirement.

• Maintenance:

1. Check for any oil leakage

2. Top up oil if level got lowered.

3. Check foundation bolts

4. Check belt condition is applicable

3.Lantle Assembly

• Its is mainly for holding shaft at centre of the kettle and give bearing in it for shaft in bearing housing in it.

• Maintenance:

1. Do greasing to bearings in bearing housing.

2. Check bearing housing bolt condition and its tightness.

3. Check condition of coupling bolts and its tightness.

4.Mechanical seal

• It use for avoiding fumes from reactor inside to come out from reactor.

•  It also help for keeping shaft concentric and avoid run out of shaft.

• Types of agitator seal

1. Single dry mechanical seal  

2. Double mechanical seal

Dry mechanical Seal

5.Thermo well

• It is for measuring temperature of chemical inside the kettle

• cylindrical fittings used to protect temperature sensors installed in industrial processes

• Typically a thermowell is made from metal bar stock

• A thermowell acts as a barrier between a process medium and the sensing element of a temperature measuring device.

• Silicon oil is use for enhancing heat transfer from process fluid to RTD rod

6.Level transmitter

 

• This instrument is for level indication inside kettle

• It may be mass or radar type
