The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam. All but a small fraction of the world's primary energy comes from fuels, and about three-quarters of that fuel ends up going into a boiler (the remainder goes into internal combustion engines , which use the fuel differently).
Coal Boilers – Coal fired boilers use coal as their fuel source. Coal is a popular choice because it is typically a relatively inexpensive fuel source. Coal has a reputation of being a “dirty” fuel source, but when handled and combusted correctly it can actually be a relatively clean, low-polluting option.
I have never run out of coal and never had to run cold in the house. My oil fired boiler has to stay on line to make hot water and uses about 1 gallon per day. When the O/S temps go below the minus zero mark the furnace does kick on to supplement the basement circulator and add some heat to the floor above where we live.
