Main Boiler: Explore its Need
Whether it’s a home or an industry, the need for the boiler is something unavoidable. The most common function for any boiler is to provide the central heating mechanism for a home, business facility, commercial complex, hospital, etc. Nowadays, there are many boilers companies in the market, but Main boilers are the most popular and preferred one among people. These boilers are available in many different combinations such as combi eco elite, combi boilers, etc.
The simple basic functions and mechanism of the boiler work together to create a contained, heat-generating combustion process. These boilers are available as both gas as well as oil central heating boilers. Boilers are like the heart of the home or can be described as the engine of a car; it provides the heat that the facility/place needs to warm up itself.
The size of the boiler has to be matched to the size of the facility or place, i.e., if the boiler is oversized, the fuel bills will be excessive, and if it is undersized, it may not generate enough heat in winter. The ideal size of a boiler is the one that moves easily on the coldest day of any year. Mostly the boilers are oversized by a minimum 30%; it is mainly because of systems calculation with a card calculator. They are always over calculated to be on the safe side.
Now, almost all the makes of boilers emphasis on energy conservation, and the heat loss calculation can be done very accurately that it avoids the need for an oversized-boilers. This eventually allows the smaller radiators and less water in the system that in turns reduces the costs of a smaller boiler during both installation and fuel bills.
For any boiler, there is nothing to be done with the number of radiators fitted to the system. All this depends upon the power of the pump and circulation of the water with the proper size of the pipe as it determines the number of radiators it can have. But the overall output of the radiator, pipes and cylinders are identified with the size of the boiler.
To be more precise in defining a boiler, we can say that the boiler is not the heating system, but it is just a part in the global heating system. These boilers are available with a standard guarantee and are easy to install and service. Generally, a heating system boiler is consisting of four main parts,
1) Boiler/burner combination
2) Piping with pumps and valves
3) Radiators and convectors
4) Control equipment with thermostat and outside temperature control
About Main Boiler with its Different Types
When it is about the main boilers, it is a company that is in the market for about 75 years and has a hands-on experience producing a variety of boilers. In general, there are two types of boilers, i.e., fire-tube and water-tube. This can be further classified as ‘high-pressure’ or ‘low-pressure’ and ‘steam boiler’ or ‘hot water boiler’.
Boilers that work higher than 15 psig are known as ‘high-pressure’ boilers. A hot water boiler is not a boiler, but it is a fuel-fired hot water heater. It is mainly because of its similarities in many ways to a steam boiler. There are different kinds of boilers such as steel boilers, cast Iron boilers, steam and condensate boiler system and hydronic boiler system, etc. Let’s explore more about the mostly used boilers in detail,
Fire Tube boilers:
In these boilers, the hot gas is available inside them, i.e., fire and the water has been made to surround the fire tubes. As the fire is inside the tubes, this boiler is known as a fire tube boiler. Now, the heat from the hot gases is allowed to manage through the walls of the tube to the water.
Water Tube Boilers:
Here the water is available inside the tubes, and the fire or the hot gas is made surrounded the water tubes.
Cast iron boilers:
These boilers may be used in steam heating or hot water applications within the scope and service restrictions of ASME BPV Code section IV. Cast-iron boilers can be found in any heating boilers for almost any application.
They are the popular replacement for large welded steel boilers that are installed during the construction of a building. They are usually installed in existing boiler rooms by moving the individual sections through the openings of doors or windows.
Steam and Condensate Boiler system:
These boilers are usually used to provide a source of hot water for facility heating and process needs. In steam and condensate systems, the heat is added to water in a boiler that causes the water to boil and form steam. Here, the steam is piped to points that require heat, and as the heat is transferred from the steam to the building area, the steam condenses to form a condensate.
In the low-pressure steam heating application, the steam distributes the piping to the boiler and see to it that the steam distributed to the pipe acts as the condensate return piping (single-pipe system).
Hydronic Boiler System:
The hydronic boiler system just heats the water and allows it to move through sealed pipes to radiators throughout the place or facility. This sealed system can also be used to heat towel rails, floor slabs, swimming pools, etc.
It heats the water at its source via super energy efficient gas boilers. Once the water is used, it is returned for reheating via a recirculating system. The heating system is separate to the homes domestic hot water supply. Here, the panel radiators operate as ‘heat emitters’ in each room, that pushes out the natural radiant heat evenly.
The recent technology enables the heat to be delivered precisely when and where it is needed. A feature of a hot water system is an expansion tank that can accommodate the expansion of the water in the system as the water is heated.
These are some of the main types of boilers that have discussed above. Thus, hope article would have given you some idea about what is a boiler and different types of boilers.
