Heat is vital in everybody's everyday lives. Whether it be heat to heat up our environments, or heat to be able to cook food, we all utilize it to some extent in our day to day activities. Water and steam are great heat carriers and are not damaging to our environment. The boiling point of water at atmospheric pressure is 100 ° C or 212 ° F. By pressurizing the boiling system by providing it an airtight seal, we can really increase the boiling point. This is how pressure cookers work. An airtight vessel to increase the pressure to increase the boiling point. This makes the food cook in a much shorter time than if an open saucepan were to be utilized. How does this compare with a commercial boiler?
How does an Industrial Boiler Work?
Well, for a start, industrial boilers can handle pressures much higher than a pressure cooker. Industrial boiler systems are often made by welding together thick steel plates, enabling extremely high pressures to be made. It has to be made extremely strong to cope with the high pressure, as failure to do so will result in forces near to a taking off bomb!
The function of a boiler is to either produce warm water or steam. Warm water boilers heat water for the purpose of domestic or industrial heating and warm water supply. Steam boilers generate steam in order to power turbines for power generation and different other commercial heating applications. To imagine the results of steam generation utilizing a boiler, think of the steam powering a turbine. When the steam travels through the blades of a turbine, the force turns the blades and accelerates the turbine. Steam contains a huge amount of energy, so it makes the turbine quite efficient and depending on the fuel utilized to boil the water, rather energy efficient too.
What are the Different Types of Boilers?
There are various types of boilers for all sorts of different applications. We are going to cover a number of the various types, including how each of the techniques is able to generate heat, so you can familiarise yourself, and be able to properly recognize them.
1. Fire-Tube Boiler
The normal make up of a Fire-Tube boiler is:
-- Water tank functioning as a boiler
There are tubes going through the water tank carrying the heat from the furnace, and the smokestack vents the heat and gases brought on by the heating effect so that the pressure does not continue to rise above the desired level. The fuel is burned inside the furnace. The tubes move the heat of the heater through the water in the tank. Once it is heated, the steam created is moved along downstream. Fire-tube boilers tend to be the most affordable type of boiler to produce, as they have a fairly easy building and construction but are usually limited for low to medium pressure applications due to the thickness of the outer shell consisting of the water.
2. Water-Tube Boiler
Now that we have covered the fire-tube boiler, let's take a look at a water-tube boiler.
The design is fairly comparable to a fire-tube boiler, however instead of the heating system heating fire tubes to heat water in a tank, the heater heats up water tubes inside the furnace. In the same way, a fuel source is burned in the heating system, triggering the water tubes inside to warm up. Once again, when the water is boiled, steam is produced and moved downstream. A water-tube boiler is more thermally effective than a fire-tube boiler, but they are more intricate to construct and the quality of the water can be a limiting factor. The water may require filtering to run most effectively.
Which Type of Fuels do Boilers Use?
Combustion is the procedure of burning a fuel source. To produce a reaction, there must be a fuel source, heat, and an oxidizing agent. Boilers can be created to burn a particular fuel, utilizing any number of different technologies, however the main component to think about here is the heat source, or otherwise known as the fuel.
The fuel is among the most essential aspects of a boiler and is what burns inside the boiler to produce the heat. There are many different sources that can be utilized.
Coal is a standard fuel source. In commercial boiler applications, the coal tends to be ground to a great powder as it burns better than conventional bricks.
Electric can be used as a heat source, either by resistance heating coils or electrode systems. Electric would generally only be used for smaller sized industrial or domestic usage. Electrode type applications require very high water quality and conductivity to work successfully. Upkeep is crucial to electrode type applications too, as cleaning up the insulators is needed to prevent arcing between the electrodes.
Gas-fired boilers work by using either gas or natural gas, whereas oil-fired boilers work utilizing fuel or petroleum-based fluid.
To create heat, we need a fuel source. By heating tubes of water, and using fire tubes to warm a tank, steam is produced at very high pressures to produce enormous quantities of energy!
