Before investing into any boiler unit of any brand,
we believe, an individual must have an idea about what is the unit; he/she is
going to buy, composed of in order to gain the maximum access over the system
and for not getting fooled by the sellers during the purchase.
article is especially composed to serve the readers with all the facts and
figures they must know about their systems, being a buyer.
A boiler is an independent combustion system that
sustains in the form of a closed vessel that is used to heat water or other
liquids or generate steam by direct application of the energy from the
combustion of fuels using electricity or nuclear energy.
For the sake of
intense understanding of the unit, the boilers are a part of the hydronic
heating system that operates to heat the house by using water to transfer heat
to a distribution source, like a radiator. These boilers are a part of the
heating system that heats the water to be distributed.
Common Boiler Outlets
The Hydronic heating system comes with 3 main
- Radiators- The water, after being boiled is pumped into the
radiators or the baseboard heaters, to give off the heat energy produced.
- Baseboard heating- Baseboard heaters, works similar to the
radiators and are installed to help the boiler heat water and send it to the
distribution channels through pipes that form the supply lines.
- Hydronic radiant floor heating-
The Hydronic radiant floor system pump the heated water from a boiler through a
tubing laid in a pattern under the floor.
All the boilers with different designs come with one
thing in common, ‘its basic parts’ that includes a burner, a combustion
chamber, heat exchanger and the pluming apparatus. Besides the basic elements,
a boiler system accommodates a bunch of other key constituents that perform
individual roles in its functioning that are worth considering.
the burner plays the heart of the boiler as it is meant to initiate the
combustion reaction within the unit. To be demonstrated technically, the
thermostat sends an electric message to the burner, according to the system
requirements for the production of heat, which then pumps the fuel in, from an
outside source, to get ignited by the burner.
chamber- whole of this reaction takes place in the combustion chamber that is
willingly and carefully constructed with cast iron to make it strong enough to
endure the temperature that can rise to several hundred degrees, usually in a
very short time. The heat generated in the process by now is transferred to the
system’s heat exchanger.
exchanger- the heat exchanger allows the heat from the combustion chamber to
heat the water in the boiler’s tank. It works to transfer the heat from the
burner to the water without getting into any direct contact with the fluid. The
heat exchanger is made of cast iron or steel to house the burner and the
process of combustion. In case of the hydronic heating system, this boiling
water is then pumped into the baseboard heaters or radiators through pipes to
give off the heat energy produced.
lines- the heated water or steam is pumped to the distribution sources through
the pipes that are marked as the supply lines.
lines- the cooled water or steam that cools down into the state of water, is
then send back to the system through a piping (or return lines), for the
purpose of re-heating.
validating its resemblance to the name, the firebox is the area where the fuel
comes in contact with the flame, producing heat to boil the water in the
boiler. Most of them are designed to be in the shape of the box, thus defining
These are actually the refractory materials that are used to fill up any gap or
openings that might occur in the firebox in order to ensure that the fire stays
in the box.
pumps- these pumps are used to inject the hot water or steam to the
distribution points in the house, via the supply lines to ensure proper
circulation in the process.
sources- In order for a boiler to heat the water or convert it into steam, a
fuel source is required to release its energy in the form of combustion. Though
boilers can run on a number of fuel sources including coal and wood, heating
oil, kerosene and liquid propane are still in common.
tank- A small tank that is placed off the main boiler, is used to protect the
system from excessive pressures.
valve- The Backflow valve is a safety device that is installed in order to
ensure the flow of water in a single direction.
aerators/Condenser- the deaerators and the condenser tanks, are used to preheat
a boilers feed water system n order to remove the oxygen from the water. To be
noted, each of the two can only be used in the steam boilers, with an
eliminated use in the hot water or oil systems. With an identical construction,
each of the two is diverged on the roads of objective. However, the principals
of thermo and vacuum are taken much into consideration while designing either
of the tanks.
For a detailed study
principle- A tank running on the thermo principle is connected to the
atmosphere and happens to be found mostly in smaller tanks where the steam is
used to maintain a temperature of around 105°C, to remove oxygen from water.
principle- A vacuum is created in the tanks by the use of an ejector pump which
causes the tank water to start boiling as a result of low temperature, which in
return, removes the air from the water. This principle is preferably used for
the steam turbine applications.
than this, there are 3 backbone components of any boiler system-
Feed Water System- It works on the regulation of the feed water to convert the
fluid into steam. There are 2 types of feed water system- in a boiler-
Additionally, there are two main sources of feed water-
steam returned from the processes
water arranged from outside the boilers plant processes
Steam System- the steam systems are meant to be responsible for the collection
and control of all the generated steam, via pipes, throughout the process,
using parts such as valves, steam pressure gauges etc.
Fuel systems- Fueling, being the heart of the process, consist of all the
necessary components to feed fuel to generate the required heat.
Each of these facts, as recommended, should be
considered by the customers, at least once before going to make a purchase.
