What is a coal fired hot water boiler?
coal fired boiler for sale
A coal fired hot water boiler is a type of boiler that generates heat to produce hot water and steam. The heat generated by the combustion of the coal is used to heat water. As with any other type of heating system, there are many benefits associated with using coal fired hot water boilers in your home or business.

How does a coal fired hot water boiler work?
Coal fired hot water boiler system
A coal fired hot water boiler is a configuration of the boiler system in which flue gases from the furnace pass through burners and then into the heat exchanger. The combustion air (oxygen) is usually provided by an air blower or fan.
There are two types of burners: natural draft and forced draft. In a natural draft boiler, air enters at the bottom of the firebox and passes up through openings in channels or tubes, which direct it to burners that heat liquid or gas to produce steam for power generation or heating purposes. Natural circulation occurs when heated water vapor rises within tubes inside boilers because rising temperatures cause changes in their physical properties such as density and viscosity; this causes buoyancy within them. Forced-draft boilers use fans to circulate air through them; they do not need any sort of external source for oxygen supply as with natural circulation systems

High efficiency coal fired hot water boiler
This is a good question. A coal fired hot water boiler’s efficiency is around 80%, while oil fired hot water boilers are approximately 70% eficiente.
The lower efficiency of an oil fired hot water boiler may be due to the higher combustion temperatures that require a large amount of additional fuel to be burned in order to keep up with the heat output needed for your home’s hot water needs.
Por outro lado, coal fired boilers typically produce lower temperatures than oil burners (around 300 graus Celsius) which means they don’t need as much supplemental heating from external sources like gas or electricity in order to maintain their high output levels.
