Boilers produce steam using heat from fuel combustion. Water tube boilers have tubes that carry water and shells that carry hot gases, allowing for higher steam pressures and capacities than fire tube boilers which have tubes that carry hot gases and shells that carry water. Key components of boilers include shells, burners, drums, furnaces, safety valves, and feed pumps. Boilers are classified by their tube configuration and common types include water tube, fire tube, and vertical or horizontal orientations. Water tube boilers have advantages over fire tube in steam generation speed, capacity, efficiency and maintenance access.
Boilers are most important part of Chemical Industry. 99 % boilers used in Pakistan Chemical Industries are water tube boilers because of their high efficiency and safety. So we should have clear understanding about the boilers.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
2. What is a boiler?
Boiler is an apparatus to produce steam. Thermal energy
released by combustion of fuel is used to make steam at
the desired temperature and pressure.
The steam produced is used for:
(i) Producing mechanical work by expanding it in steam
engine or steam turbine.
(ii) Heating the residential and industrial buildings
(iii) Performing certain processes in the sugar mills,
chemical and textile industries.
4. Boiler properties

conditions.
b). Accessibility: the various part of boiler should be
accessible for repair & maintenance.
c). Capacity: Should be capable of supplying Steam
according to the requirements.
d). Efficiency: Should be able to absorb a maximum amount
of heat produced due to burning of fuel in the furnace.
e). It should be simple in construction.
f). Its initial cost and maintenance cost is low.
g). It should be capable of quick starting and loading.
6. Fire Tube Boilers
The combustion gases pass inside boiler tubes, and heat is
transferred to water on the shell side.
• Relatively small steam capacities (12,000
kg/hour)
• Low to medium steam pressures (18 kg/cm2)
• Operates with oil, gas or solid fuels
8. Water Tube Boilers
In this type of boiler water passes through the tubes while the
gases remain in the shell side, passing over the tube surfaces
• Used for high steam demand and pressure requirements
• Capacity range of 4,000 – 120,000 kg/hour
• Combustion efficiency enhanced by induced draft fans.
• Lower tolerance for water quality and needs water

valve that automatically opens when
pressure attains the valve setting.
Used to prevent excessive pressure
from building up in a boiler.
STEAM SEPARATOR - A device
for removing the entrained water from
steam.
14. BOILER MAIN
COMPONENTS
STRAINER - A device, such as
a filter, to retain solid particles
allowing a liquid to pass.
SIGHT GLASS- A glass tube
used on steam boilers to give a
visible indication of the boiler's
water level
15. BOILER MAIN
COMPONENTS
DRAIN - A valve connection
at the lowest point for the
removal of all water from the
boiler.
FEED PUMP - A pump that
supplies water to a boiler.
16. BOILER MAIN
COMPONENTS
Ash Pit
The ash pit is the space where
ashes accumulate under the
fire. The ashes fall through the
fire grate into a (often)
removable box.
Grate
The Grate is a series of bars or
narrow plates in the bottom of
the fire box. The ashes fall
through the grate into the ash
pit.
17. BOILER MAIN COMPONENTS
Pressure Gauge. This
indicates the pressure of the
steam in the boiler.
Fusible Plug . A fusible plug
operates as a safety valve when
dangerous temperatures,
rather than dangerous
pressures, are reached in a
closed vessel.
18. BOILER MAIN COMPONENTS
Feed Check Valve. The
high pressure feed water is
supplied to the boiler
through this valve. This
valve opens towards the
boiler only and feeds the
water to the boiler.
Steam Stop Valve.
It regulates the flow of
steam supply outside.
19. Type of fire tube boiler
Cochran Boiler
It is a multi-tubular vertical fire tube
boiler having a number of horizontal
fire tubes. This is the modification of a
simple vertical boiler where the heating
surface has been increased by means of
a number of fire tubes.
It is very compact and requires
minimum floor area.
Any type of fuel can be used with this
boiler.
Well suited for small capacity
requirements.
20. Type of fire tube boiler
Lancashire Boiler
It is stationary fire tube, internally fired, horizontal,
natural circulation boiler. This is a widely used boiler
because of its good steaming quality and its ability to
burn coal of inferior quality.
This boiler is set in brickwork forming external flue so
that the external part of the shell forms part of the heating
surface.
22. Type of fire tube boiler
LOCOMOTIVE
BOILER.
Locomotive boiler is a
horizontal fire tube type
mobile boiler. The main
requirement of this boiler
is that it should produce
steam at a very high rate.
Therefore, this boiler
requires a large amount of
heating surface and large
grate area to burn coal at
a rapid rate.
23. Type of water tube boiler
Simple vertical boiler
A vertical boiler is a type of water-
tube boiler where the boiler barrel
is oriented vertically instead of the
more common horizontal
orientation. Vertical boilers were
used for a variety of steam-
powered vehicles and other mobile
machines, including early steam
locomotives.
24. Type of water tube boiler
Stirling boiler
The Stirling boiler is an early
form of water-tube boiler, used to
generate steam in large land-
based stationary plants.
Stirling boilers are one of the
larger arrangements for a water-
tube boiler. They consist of a
large brick-built chamber with a
sinuous gas path through it,
passing over near-vertical water-
tubes that zigzag between
multiple steam drums and mud
drums.
25. Type of water tube boiler
Babcock and Wilcox boiler
The longitudinal drum boiler
is the generally accepted
standard of Babcock &
Wilcox construction. The
cross drum boiler, though
originally designed to meet
certain conditions of
headroom, has become
popular for numerous classes
of work where low headroom
is not a requirement which
must be met.
26. MERITS OF WATER TUBE BOILERS
OVERFIRE TUBE BOILERS
1. Generation of steam is much quicker due to small
ratio of water content to steam content. This also helps
in reaching the steaming temperature in short time.
2. Its evaporative capacity is larger and the steam
pressure range is also high-200 bar.
3. Heating surfaces are more effective as the hot gases
travel at right angles to the direction of water flow.
27. MERITS OF WATER TUBE BOILERS
OVERFIRE TUBE BOILERS
4. The combustion efficiency is higher because complete
combustion of fuel is possible as the combustion space is
much larger.
5. The thermal stresses in the boiler parts are less as
different parts of the boiler remain at uniform temperature
due to quick circulation of water.
6. The boiler can be easily transported and easily its
different parts can be separated.
28. MERITS OF WATER TUBE BOILERS
OVERFIRE TUBE BOILERS
7. Damage due to the bursting of water tube is less
serious. Therefore, water tube boilers are sometimes
called safety boilers.
8. All parts of the water tube boilers are easily accessible
for cleaning, inspecting and repairing.
9. The water tube boiler's furnace area can be easily
altered to meet the fuel requirements.
29. Demerits :
1. It is less suitable for impure and sedimentary water, as a
small deposit of scale may cause the overheating and
bursting of tube. Therefore, use of pure feed water is
essential.
2. They require careful attention. The maintenance costs
are higher.
3. Failure in feed water supply even for short period is
liable to make the boiler over-heated.
