Coal burning boilers are a popular choice for those heating their homes and businesses. They’re highly efficient, able to produce large amounts of heat at a low cost. But how do coal burners work? What are the different types of coal? And how much does one cost? Let’s find out!

How does a coal burning boiler work?
A coal-fired boiler works by burning coal to produce steam, which is used to drive a turbine. The turbine produces electricity that’s fed to your home as alternating current (AC).
As you might imagine, a process this complex requires several steps. Here’s how they break down:
- Coal is burned in the boiler of the power plant and produces carbon dioxide gas and heat energy. The heat is transferred from the firebox via pipes called “flues” through either water tubes or flue gas passageways in order for it to reach its maximum temperature.
- The hot gases then travel through large fans until reaching an area where they’re forced into combustion chambers with openings where burners are positioned so as not only keep flames strong enough but also move them toward walls where there’s no oxygen available yet still give off enough pressure needed for efficient heating purposes without overheating any part within itself (this includes other sections near yours).
What are the different types of coal?
There are a few different types of coal. The most common, and the type that you’re likely to encounter during your search for a boiler, is anthracite. Anthracite is hard and black with a high carbon content. It’s very dense and can burn at temperatures above 1,500 degrees Celsius (2,732 degrees Fahrenheit).
Anthracite is often referred to as “hard coal” and other varieties are considered “soft.” Soft coals have lower carbon contents than hard coals; they also tend to be less dense. Bituminous coal has a medium-high carbon content and burns at temperatures from 900°C to 1600°C (1,652°F – 3137°F). Lignite is softest of the three types mentioned here; it’s commonly called brown or sub-bituminous due its dark brown color.
How does a coal burning boiler burn?
When you light a fire, you’re actually starting combustion—an exothermic reaction that releases heat and produces ashes (carbon dioxide). The carbon in your coal is burnt to form carbon dioxide and ash (inorganic material such as minerals). This reaction occurs at high temperatures in airtight furnaces where there is sufficient oxygen available to support combustion.
The hot gases produced by combustion rise up through brickwork and pass through flues or ducts that lead outside your home before exiting through chimneys or stacks on top of buildings. As these gases rise they transfer heat into structures around them which means they don’t need any extra fuel to keep themselves warm; they just need enough oxygen (and sometimes steam) so they can continue burning efficiently without getting too hot or decreasing their effectiveness over time!
Are coal burning boilers efficient?
Are coal burning boilers efficient? The answer is yes. Coal burning boilers are more efficient than wood burning boilers, gas burning boilers and oil burning boilers. This is because the heat generated by coal is used to produce steam which turns the generator for electricity production. In comparison with wood-fired boilers, coal-fired ones do not require a chimney to exhaust gases produced during combustion into atmosphere. Instead of releasing this carbon monoxide and sulphur dioxide into your home’s living space or garden; these gases are piped away from your property through flues (tubes) fixed above ground level.
Is it cheaper to burn coal or wood?
The answer to this question is simple: coal is always cheaper than wood.
- Coal is cheaper to buy. Coal prices are typically fixed, while wood prices vary from season to season and from region to region.
- Coal is cheaper to transport because it’s heavier and easier to handle than wood.
- Coal costs less money for storage, as well as the time it takes for you to fetch it from the storage site and bring it home or load into your stove, etc…!
- Finally, burning coal is usually more efficient and therefore cheaper than burning wood: You get more heat out of each pound of coal than out of each pound of wood!
How much does a coal burning boiler cost?
A new coal-fired boiler can cost anywhere from $8,000 to $100,000 depending on the size and brand of the unit. The average price for this type of boiler is around $20,000. The cost depends on factors such as:
- Size: Smaller spaces usually require smaller boilers that don’t need to heat as much water at one time; therefore they will be cheaper than large ones with larger capacities.
- Efficiency: More efficient boilers are more expensive because they require less fuel and produce less waste heat during operation.
The coal burning boiler is a great choice for homeowners who want to save money on their heating bills and still get the power they need. It’s also very easy to maintain, as long as you keep up with annual maintenance checks from a professional technician.
