Title of micro project:-Prepare Report on
different boiler mountings

Brief
introduction:

The various boiler mountings and accessories that are used in
steam boilers are water level indicator, pressure
gauge, safety valves, stop valve; blow off Valve, feed check valve, fusible
plug, air pre-heater, super heater,
economizer and feed pump. The boiler mounting and
accessories are used
in steam boilers for its proper, efficient and satisfactory working. In this article, we will discuss the functions of each of
them

Aim of Micro-Project:-

·             
To study the working and function of mounting
& accessories in boiler.

·             
To know about different boiler mounting

FUNCTION, LOCATION, AND WORKING OF
MOUNTINGS AND ACCESSORIES.

A) SAFETY VALVE: The function of the safety valve
is to permit the steam in the boiler to escape
 to the atmosphere when pressure in the steam space in the
boiler. The safety valve operates in
. the principle that a valve is pressed against its seat
through some agency such as start, screw or
spring by external weight or
force, when the steam force due to boiler pressure acting under
the valve
exceeds the external force, the valve gets lifted off its seat and some of the
steam
rushes out until normal pressure is restored again.

‘WATER LEVEL INDICATOR:
The
function of the water level indicator is to ascertain constantly
exactly the
level of water in the boiler shell. It is fitted in the front of the boiler
from where
easily visible to the operator. he unit consists of a strong
glass tube who
se ends pass through stuffing boxes consisting of heat
resisting rubber packing to prevent leakage
steam and air. The flanges are bolted to front end plate of
the boiler, the upper flange being fitted to e steam space
and the lower to water
space
in the boiler.

FUSIBLE PLUG: The function
of the fusible plug is to extinguish the fire in the event of the boiler
shell failing
below a certain specified limit. We know that when the water on heating
transforms
into steam, the level of water in the boil. If the water is not
replenished
and the steam generation continues then the parts, which
have been uncovered by water
uncovered by water may get overheated and subsequently
are melted. To safeguard against
this eventuality
we use fusible plug.

PRESSURE GAUGE: Each boiler
has to be provided
with a pressure gauge, which record the pressure at
which the
steam is being generated in the boiler.

3.

5. Blow off Valve

6.

Pressure gauge is usually mounted at the Iron!: top of the boiler shell or
drum. The gauge should to
clearly visible to the attendant so that he can easily
record the pressure reading.

The function of various boiler mountings and accessories
are

1.Water
Level Indicator

It is fitted in front of
the boiler and generally present two in number.

It is
used to indicate the water level inside the boiler. It shows the
instantaneous level of water
that is present inside the steam boiler which is necessary for
its proper working.

2.Pressure
gauge

It is also present in front of the boiler.

It is
used to measure the pressure of the steam inside the boiler.
The pressure gauges
generally used are of Bourden type

3.Safety Valves

Safety valves are attached to the steam boiler chest.

It is used to prevent explosion due to excessive internal pressure.
When the internal pressure
inside the boiler exceeds its working
pressures than the safety valves blow off the steam and
maintains the internal
pressure.

Generally two safety
valves are present on a boiler.

4.Stop Valve
(steam stop valve)

It is usually fitted on the
highest part of the boiler with the help of a flange. The main function of
the stop valve is

To
control the flow of steam from the boiler to the main steam pipe.
To
completely shut off the steam supply when required.

5.Blow
off Cock

It is fitted at the bottom of the boiler
drum.
The functions of blow-off Valve is

To
empty the boiler whenever required.

To
discharge
the
scale, mud and sediments which gets collected at the bottom of the boiler?

6. Feed Check Valve

     It is non-return valve and fitted to a screwed spindle to
regulate the lift.

It is
fitted to the shell slightly below the normal water level of the boiler. A
boiler must have its
spindle lifted before the pump is
started.

Aim of micro- project

·   To study the working and function of mounting &
accessories in boiler.

·   To know about different boiler mounting
