Cleaning chimneys and stoves is important, and it adds to the cost of burning wood. Coal, in contrast, generates no creosote. Coal ignites at a temperature more than 100 degrees higher than wood, and it requires a hot bed of wood coals to get it started. Being far denser than wood, coal burns more steadily and longer.
Does coal or wood produce more heat?
Wood can be a bit more variable in heat production. While coal tends to burn hotter, we know enough about various kinds of wood and how to treat them to create hot-burning, consistent logs from the cultured forests grown.
Why is it better to burn wood than coal?
Burning wood is not CO2 free; it releases carbon, stored over the previous decades, in one quick burst. For an equal amount of heat or electricity, it releases more CO2 than burning gas, oil and even coal, so straight away we have more CO2 in the air from burning wood.
Is fire hotter than coal?
Are Coals Hotter Than Flames? No, given all else being equal, coal has the same potential heat as the wood beginnings, but due to the lack of oxygen and surface area, they produce less heat. Yellow flames show they’re hotter than the red coals.
Is coal a good heat source?
Coal was a dominant source of heat for American homes for much of the late 19th and early 20th centuries. But coal, primarily used today in power plants and steelmaking, has not been used for heating on a large scale for decades.

Does coal burn cleaner than wood?
* Also, dry wood lights easily, but a coal fire requires much more kindling to get it going. Further, wood burns cleanly, while coal smoke is considered dirty. If you do use coal, anthracite is a relarively clean-burning fuel with a low sulfur content.
How long will a ton of coal last?
Results may vary, but the average burn time between loads ranges from 8-24 hours. These burn times may exceed the averages, depending on the situation as every situation is different. How many BTU’s are in Anthracite Coal? There are around 13,500 BTU per pound of Anthracite Coal.
Can you burn coal and wood together?
Burning coal and logs together can produce a gorgeous fire, with the aroma and long flames of a log fire, combined with the high heat output and longevity of solid fuel. Your fire can burn hotter, and for longer.
Why do coals stay hot?
Embers (hot coals) can exist within, remain after, or sometimes precede, a fire. Embers are, in some cases, as hot as the fire which created them. This is because embers radiate a more consistent form of heat, as opposed to an open fire, which is constantly changing along with the heat it radiates.
Why do coals glow red?
(i) A coal or charcoal burns with just a glow red and gives out heat without flame however LPG burns with flame, this is because a flame is produced only when gaseous substances burn. When wood or charcoal is ignited, the volatile substance present in it vapourizes and burns with a flame in the beginning.
How hot can wood coals get?
The gases burn and increase the temperature of the wood to about 600 degrees Celsius (1,112 degrees Fahrenheit). When the wood has released all its gases, it leaves charcoal and ashes. Charcoal burns at temperatures exceeding 1,100 degrees Celsius (2,012 degrees Fahrenheit).
What type of coal is best for heating?

What is the major disadvantage of using coal for energy?
