kivihiillilämmitys

Kivihiillilämmitys refers to the heating of buildings or spaces using coal as a fuel source. This method has been historically significant in many parts of the world for both residential and industrial heating. Coal combustion releases thermal energy which can then be used to warm air or water, which is then circulated through a building's heating system.

The process typically involves a coal-fired boiler or furnace. Coal is fed into the combustion chamber, where it burns. The heat generated is transferred to water or air, which is then distributed via pipes or ducts. The byproducts of coal combustion, primarily ash and flue gases, need to be managed and vented.

While effective, kivihiillilämmitys has environmental drawbacks. The burning of coal releases pollutants into the atmosphere, including sulfur dioxide, nitrogen oxides, particulate matter, and greenhouse gases like carbon dioxide. These emissions can contribute to air pollution, acid rain, and climate change. Due to these environmental concerns, many regions have phased out or are phasing out coal for heating purposes, opting for cleaner alternatives such as natural gas, electricity, or renewable energy sources. However, in some areas, particularly where coal is readily available and affordable, it may still be used for heating.
