4. ABSTRACT
A Dust collector is a system used to enhance the quality of air released from
industrial and commercial processes by collecting dust and other impurities
from air or gas. Designed to handle high-volume dust loads, a dust collector
system consists of a blower, dust filter, a filter-cleaning system, and a dust
receptacle or dust removal system.

CHAPTER 1
INTRODUCTION
As per “THE INDIAN BOILERS(AMENDMENT ) ACT2007
A ‘Boiler’ means a pressure vessel in which steam is generated for use external
to itself by application of heat which is wholly or partly under pressure when
steam is shut off but does not include a pressure vessel
With Capacity less than 25 ltrs (such capacity being measured from the
feed check valve to the main steam stop valve);
With less than 1 kilogram per centimeter square design gauge pressure &
working gauge pressure; or In which water is heated below one hundred degree
centigrade .

1.1 BOILER
FIG.1.1
1.1.1 FUNCTION OF BOILER
The main function are
1. Generate the steam at desire pressure.
2. The steam generation rate is high.
3. Provide a appropriate surface area to transfer heat from gas to water.
4. Safely operation
5. Convert steam into super heated steam if desire.
6. Avoid the explosion due to high pressure inside the boiler.
13. 3
1.1.2 TYPES OF BOILERS
Though there are many types of boiler
According to the axis of boiler:
1. Horizontal boiler
2. Vertical boiler
3. Inclined boiler
According to fire:
1. Externally Fired boiler
2. Internally fired boiler
According to pressure of boiler:
1. High Pressure boiler
2. Low pressure boiler
According to circulation of water:
1. Forced circulation boiler
2. Natural circulation boiler
14. 4
According to circulation of gases:
1. Fire tube boiler
2. Water tube boiler
1.1.3 ADVANTAGES OVER OTHER TYPES
1.Lower operating costs.
2.Reduces risks.
3.Increased productivity.
4.Improved product quality.
5.Improved health and safety.
6.Work safe compliance.
7.Better morale and employee retention.

1.2 DUST COLLECTOR
A dust collector is a system used to enhance the quality of air
released from industrial and commercial processes by collecting dust and other
impurities from air or gas. Designed to handle high-volume dust loads, a dust
collector system consists of a blower, dust filter, a filter-cleaning system, and a
dust receptacle or dust removal system. It is distinguished from air cleaners,
which use disposable filters to remove dust.
FIG 1.2
16. 6
1.2.1 FUNCTIONS OF DUST COLLECTOR
under the function of centrifugal force, the dust is gathered upon the inner wall
of the cyclone dust collector, and then upon the function of gravity, the dust
finally falls down and comes out through the discharging hole. The water
vapour goes out into the atmosphere through the top tube
1.2.2 TYPES OF DUST COLLECTOR
1.Inertial separators
2.Fabric filters
3.Wet scrubbers
4.Unit collectors
5.Electrostatic precipitators
17. 7
1.2. ADVANTAGES OF DUST COLLECTOR
1. Reduces the risk of fire and dust explosion.
2.Enhances safety: Increases visibility at the work place.
3.Dust suppression prevents unpleasant odors.
4.Reduces site maintenance and cleaning costs.
5.Reduces equipment wear hence saving money.
6.A healthier workplace helps boost employees' morale.
7.Reduces waste of valuable materials.

CHAPTER 2
METHODOLOGY
A fabric filter consists of several filter bags made of filter
cloth sewn into cylindrical shapes and support frames that support the filter
cloth. Process gas is filtered on the surface of the filter cloth, and purified gas
flows out.
The collected dust is removed from the filter cloth through cleaning methods
such as the pulse-jet method and the pulsative reverse pressure method.
2.1LINE DIAGRAM OF PROCESS:

2.3 WORKING PRINCIPLE:
It is distinguished from air cleaners, which use disposable filters to remove
dust.Cyclone dust collector consist of intake tube, exhaust pipe, cylinder, cone
pipe, dust bucket.
Cyclone dust collector has the features of simple structure, easily
manufacturing, easy installation and maintenance, low invest cost and
maintenance cost, etc. It is widely used to separate the dust from the water
vapour inside the airflow.
The airflow with dust is rotating in high speed in the cyclone dust collector,
under the function of centrifugal force, the dust is gathered upon the inner wall
of the cyclone dust collector, and then upon the function of gravity, the dust
finally falls down and comes out through the discharging hole. The water
vapour goes out into the atmosphere through the top tube.

2.4 WORKING PROCESS:
The basic working principle of boiler is very very simple and easy to
understand.The boiler is essentially a closed vessel inside which water is
stored.Fuel (generally coal) is bunt in a furnace and hot gasses are produced.
These hot gasses come in contact with water vessel where the heat of these hot
gases transfer to the water and consequently steam is produced.Then this steam
is piped to the turbine.There are many different types of boiler utilized for
different purposes like running a production unit, sanitizing some area,
sterilizing equipment, to warm up the surroundings etc.Then process goes
through the plate arrangement in the tank which is filled with water.the dust
particles in the air will be cleaned when they go zig zag in water.If the air is not
cleaned properly in the plate.Then the air will be cleaned before it goes out of
the chimney.

CHAPTER 4
CONCLUSION
From the above process we can control the air pollution due a boiler steam.By
this we can prevent the environment from being pollute
4.1 SCOPE FOR A FUTURE WORK
Future scope of our project is to be sure to protect yourself and your employees
when working with products that produce dust. The health risks of not having
clean air that is free from irritants and toxins can be devastating and even life-
threatening. To see how a cyclone dust collector can improve your indoor air
quality, contact a industrial ventilation professional today.

ADVANTAGES:
1.Lower operating costs.
2.Reduces risks.
3.Increased productivity.
4.Improved product quality.
5.Improved health and safety.
6.Worksafe epa compliance.
7.Better morale and employee retention.
DISADVANTAGES:
1.Steam output pressure cannot be very high since the water and steam are
enclosed in the same vessel
2.The steam received from the fire tube boiler is not very dry.
3.The efficiency of heat transfer is bad since the heat exchanger does not use
thermal radiation.
