The best coal boilers are priced at around $2,800 – $15,600, The cost of a coal boiler can vary depending on the size and type. Coal boilers are used to heat large buildings and businesses. Coal is the most efficient fuel for large-scale heating systems, but it has its drawbacks. Here we explain why you might want to consider using a coal boiler, what makes them so efficient, and how much they cost to run.
What are coal boilers?
A coal-fired boiler is basically a type of equipment used to generate heat by burning coal. It’s like a big furnace that heats up water to produce steam. It can then be used for various purposes like heating buildings or generating electricity. People use coal-fired boilers because they’re an older and established way to produce heat and energy. Гэсэн хэдий ч, they can also be a bit polluting since burning coal releases emissions into the air.
Working Principle.
Coal boilers are a type of heating system that uses coal as fuel. They are fueled by burning coal and then using the heat generated from this process to produce hot water, which is then circulated throughout the home. In addition to using coal for heat, some boilers can also be used as an air-conditioning unit in summer months by circulating cold air throughout your home.
Boiler systems come in a few different variations: there are those that utilize gas or oil as their primary source of fuel. There are those that use electric resistance coils to generate heat, and there’s even one (called an integrated producer) that combines all three forms of energy so you don’t have to switch fuels when your needs change!
Application Field.
- Power Generation: Coal-fired boilers are widely used in power plants to generate electricity. The steam produced by these boilers drives turbines connected to generators, producing electrical power.
- Industrial Processes: Many industries, such as manufacturing, chemical processing, and paper production, require steam for their processes. They provide the necessary heat to create steam for these industrial applications.
- Халаалт: Coal-fired boilers are also used to provide heating for residential, commercial, and institutional buildings. They can be used in central heating systems to distribute warmth throughout large areas.
- Cement Industry: The cement manufacturing process involves high-temperature processes that require a significant amount of heat. They are often used to provide the heat needed for cement production.
- Нэхмэлийн үйлдвэр: Textile factories use steam for various processes, such as dyeing, drying, and finishing. They can supply the necessary steam for these operations.
- Food Processing: Certain food processing operations, like cooking and sterilization, require steam. They can be employed to provide the heat needed for these processes.
- Pulp and Paper Industry: In addition to producing steam for various processes. They are used in the pulp and paper industry for tasks such as pulp digestion and paper drying.
- Химийн үйлдвэр: Chemical manufacturing processes often require high temperatures for reactions and other operations. They can provide the necessary heat for these processes.
- Oil Refineries: Some oil refineries use coal-fired boilers for heating and other energy-intensive processes.
- Steel Industry: Coal-fired boilers can be used in steel production for processes like heating furnaces and powering machinery.

Generally, the efficiency of coal-fired boilers can range from around 70% руу 90%. Modern high-efficiency designs achieve the higher end of this range.
To provide some context, let’s compare the efficiency of coal-fired boilers to other common heating and energy sources:
Natural Gas: Natural gas-fired boilers are known for their relatively high efficiency. Modern gas-fired boilers can achieve efficiency levels of around 90% or even higher. This is due to the cleaner and more complete combustion of natural gas compared to coal.
Газрын тос: Oil-fired boilers typically have efficiency levels similar to those of coal-fired boilers, ranging from 70% руу 90% depending on the specific design and technology used.
Цахилгаан: Electric boilers are often considered highly efficient because they convert nearly all of the energy they consume into heat. Гэсэн хэдий ч, the overall efficiency of an electric boiler is influenced by the source of the electricity. If the electricity is generated from fossil fuels like coal or natural gas, then the efficiency at the power plant needs to be taken into account as well.
Types of Coal.
When it comes to choosing coal for your boiler, there are three main types: hard coal, soft coal, and pulverized coal.
Hard coal is the best option for boilers as it provides a high heat output. It’s also very efficient in terms of space, as you can use up to 30% less hard coal than other types of fuel.
Soft coal doesn’t give off as much heat as hard or lignite coals but still produces plenty of energy with its medium-low calorific value (about 4500kJ/kg). This makes soft coal suitable for small boilers that don’t need too much power from their fuels.
Pulverized coal is a good option for those who want to save money on their heating bills. It has the lowest calorific value of all three types of coal, at around 4000kJ/kg. The pulverized coal is the lowest quality coal and has a low flammability rate. It’s best used for heating large buildings such as schools, hospitals, and factories.
How Much Coal is Needed For a Coal Boiler?
If you’re considering a coal boiler, how much coal is needed for a boiler?
The answer is that it varies depending on the size of your home and many other factors. Most boilers are sized to burn 1 ton of coal per day. A ton of coal will last one to two days depending on how cold the weather is and whether or not you have backup heating in case there’s no fuel available in your area.
1 ton of coal is roughly equivalent to 2-3 tons of wood, so if you want more heat than this then perhaps a wood stove would be better suited for your needs. You should also consider that it takes longer to get started with a new boiler than with any other type of heating system – up to 24 hours during which time they won’t produce hot water or heat at all.
Coal Boiler Cost
The cost of a coal boiler can vary depending on the size and type. Жишээлбэл, an coal boiler installed in your backyard will cost more than one that’s installed indoors and connected to your home’s water heater.
The average price of a small coal boiler is around $3,000, while large models typically cost between $5,000 болон $8,000 or more. The most expensive option is an industrial-sized model that costs as much as $15,000 depending on its size and features!
To help you decide how big your home needs to be heated by this renewable energy source, here are the costs for some common sizes:
- Small (1 ton = 12000 BTUs): These are designed for a small house or cabin up to 1000 square feet. They use four cubic feet of wood per hour and can run 24/7 without any problems as long as they have adequate access to wood and water supply nearby. The average price is around $800-$1200 depending on model type (e.g., wall mount vs air cooled).
- Medium (2 tons = 24000 BTUs): Suitable for homes with living areas between 1200 – 1500 sq ft or larger cabins with loft space included in total square footage count such as doublewide mobile homes where loft area counts towards overall floor area calculation making it more expensive than normal square footage based calculations would be otherwise.”
