A boiler is a device which utilizes the energy extracted from the combustion heat to produce steam. The steam is then used to undertake the desired residential functions.
There are different types and sizes of boilers available in the market, depending upon the heating output, types of combusting material and the emission controls.
Some boilers only produce hot water while others produce steam.
The boilers can be classified into three basic types such as:
- Fire tube boilers
- Water tube boilers
- Electric boilers
In the fire tube boilers, the gases circulate in the tubes submerged in water. These gases, after continually passing the tubes, circulate their heat to the water through the tube walls. This causes the water to boil and the boiler operation is performed.
There are water filled tubes in the water tube boilers, through which the gas flows. These water filled tubes are connected to large containers known as drums. The electric boilers use electricity to perform the required operation. These boilers are used for most of the HVAC applications.
The residential boiler piping schematics is an important point to consider for the efficient operation of the boilers. A well integrated piping system ensures the proper functioning of the feed water systems, fuel and the steam system. Water is being fed to the boiler through the feed water system. There are valves in the feed water system, which automatically adjust as per the requirement of steam.
The fuel system is a means to provide the required fuel to the boiler in order to undergo the required operation. And, the steam generated is carried through the steam system to the specified point of output. HVAC Design services helps clients to come up with accurate and efficient residential boiler piping schematics.
There are certain important points to consider regarding the residential boiler piping schematics for the efficient functioning of the boilers. The circulating pump should be placed downstream of the expansion tank so as to ensure that the head pressure developed by the pump adds to the fill pressure of the system.
